1. GENERAL INFORMATION 1.1 PULSE RADAR GAUGE DESCRIPTION: The evo 2600 utilizes pulsed Frequency Modulated Continuous Wave (FMCW) technology operating in the K-Band frequency range of approximately 26GHz. By utilizing such technology, the evo 2600 is able to provide a standard accuracy of +/- 3mm. The Kband 26GHz frequency allows the radar to produce narrower conical beam angles than a standard 6GHz frequency radar gauge. This allows the radar gauge to be installed close to the tank walls and will help reduce interference from obstructions inside the tank. Another added benefit is the reduced size of the antenna due to the narrower beam angle, which also allows for easier installations than standard radar level gauges. There are numerous antenna configurations available for the evo 2600. The different antenna options include a standard 316SS conical horn antenna, parabolic antenna, and planar antenna. Each antenna can accommodate specific applications and process conditions. In its standard configuration, the evo 2600 is a two-wire loop-powered device. As with all L&J engineering products, the evo 2600 supports a multitude of digital protocols and external power supply options. This allows the user to easily interface the evo 2600 with any existing or future inventory management system. The evo 2600 uses L&J's communication highway module that allows you to easily switch protocols if your applications changes. A wireless version of the radar gauge is also available.

1.2 FACTORS AFFECTING ACCURACY: Outside influences can affect the accuracy of the installed radar gauge. These influences include but are not limited to the following: Surface Conditions - This includes foaming, boiling, heavy vapors and turbulence at the product surface that could degrade the quality of the signal being reflected. Antenna Conditions - The size and shape of an antenna affect the quality of the transmitted and received signals. A more focused signal (like with the parabolic antenna) gives a stronger reflection. Other influences include to a lesser extent, dirt or condensation on the antenna and the size and shape of the point of entry into the tank. Distance - For a greater distance there is a greater loss to the signal due to normal absorption by the air and vapors. Reflected energy will be weaker at greater distances. Dielectric Constant - Every product has a dielectric. A product with a high dielectric constant (like Water with 80) will reflect more energy while a product with a low dielectric constant (like hydrocarbons with 1.7 to 3.5) will reflect less energy. A higher dielectric constant means greater accuracy and reliability.

Obstructions - The presence of support structures, pipes, tubes, heaters and mixing blades can adversely affect the level reading because those items reflect the signal which would normally reflect from the liquid surface. Datum - The datum, or mounting height of the radar gauge should be constant and stable regardless of the liquid level in the tank, weight on top of the tank, or pressure inside the tank. Since the principle of operation involves measurement of the distance between the datum and the liquid surface, a stable mounting point is critical.

1.3 BACKGROUND OF THE USER: It is assumed that the person using this guide have some familiarity with the functions and operations of the total operating system in general, in that the radar gauges are only one component part of a much larger tank gauging system. For this reason, the person maintaining the equipment should become familiar with other equipment connected to and working in conjunction with the evo 2600. The person maintaining the equipment will find it helpful to have actually operated the equipment before receiving maintenance responsibility.

2.2 MECHANICAL MOUNTING AND LOCATION: The evo 2600 Radar Gauge can be adapted to mount on a number of different tank configurations. Typical mounting configurations include, but are not limited to: 1) Fixed Roof 2) Spherical 3) Still Well (existing on tank) 4) Integral Still Well (float and tape retrofit) Each of these installations is covered in detail for application with the standard conical antenna. Refer to addendum supplied with the evo 2600 if your mounting configuration is not covered in this section. The Radar Gauge must be mounted to a mating flange of the same size as is supplied with the gauge. The standard mounting connection is 2" NPT. Other flange configurations and material are available using adapter flanges. Use caution when tightening the flange - excessive or uneven torque can stress and crack the flange/housing! Use of an appropriate gasket is required to prevent leaking, especially in high-pressure applications. The mounting must be level on the tank and of sufficient strength to support the weight of the gauge. The opening in the tank must be free of any obstructions and allow for free two-way propagation of the radar beam. If this is not possible, then special profiling software is available to allow the radar gauge to "look around" obstructions. Be aware that depending on the nature of the obstruction, some degradation of accuracy may occur in the immediate vicinity of the obstruction. The Radar Gauge should be oriented to allow for easy viewing of the display. Before applying power, the explosion-proof dome on the electronics chamber end should be removed and the boards and cable(s) (if equipped) checked to make sure nothing has come loose or damaged in shipping. The evo 2600 was designed for both high pressure and low-pressure tanks. The internal configuration of all models includes a waveguide adapter to transfer the RF energy to/from the antenna. The waveguide adapter physically isolates the tank pressure from entering the electronics chamber. Make certain the unit you are installing is rated for the intended application. CAUTION! The Radar Gauge is shipped with the antenna removed. The antenna may be damaged when transporting or moving the gauge with the antenna mounted. Install the antenna as shown in the drawings shipped with your gauge.

2.2.1 Fixed Roof Installation (See Drawing Page 11, Figure 1.A) STEP 1 - Check inclination of mounting flange. For maximum accuracy, it should be 0-4o inclined toward the center of the tank. The antenna's field of view should be free of interfering obstructions. If the above requirements cannot be met, contact the factory for assistance.

STEP 2 - Install the gauge by mounting on available flange or NPT fitting. (Skip if antenna fits through opening) STEP 3 - Install the antenna on the bottom face of the waveguide adapter using the mounting screws provided. STEP 4 - If antenna fits through opening, install the radar flange on the mounting flange. Use an appropriate sealing gasket (not supplied) for the application involved (product type, pressure, temperature, etc.). Tighten the mounting bolts - DO NOT OVERTIGHTEN OR DAMAGE TO HOUSING MAY OCCUR. STEP 5- Install conduit and all conduit seal-offs or cable glands. Seal-offs must be installed within 18" of all condulet openings. Seal-off must be properly packed after installation of field wiring. STEP 6 - Follow start up procedure described in this manual.

2.2.2 Spherical Tank Installation (See Drawing Page 11, Figure 1.C) The same mounting instructions for the fixed roof tank apply, with the exception that a 02o inclination from the tank's centerline is required.

2.2.3 Still Well Installation (See Drawing Page 11, Figure 1.B) STEP 1 - Check inclination of mounting flange. For maximum accuracy it should have a 02o inclination from centerline of still well pipe. The antenna's field of view should be free of interfering obstructions. If the above requirements cannot be met, contact the factory for assistance. STEP 2 - Install the antenna on the bottom face of the waveguide adapter, using the mounting screws provided. STEP 3 - 5 Same as 2.2.1-Fixed Roof Installation

2.2.4 Floating Roof Installation Consult factory for floating roof installations.

2.2.5 Riser and Cleaning Hatch Installation (See Drawing Page 11, Figure 1.D) 2.2.5.1 RISER Most tanks are fitted with a short riser pipe for the installation of equipment. The opening of the antenna should be flush with or protrude through the tank opening below the tank roofline. 2.2.5.2 CLEANING/GAUGING HATCH

Fax: (708) 236-6006


Page |13

A cleaning/gauging hatch may be implemented using a hinged base or manhole cover that would allow full access to the interior of the antenna and base when opened. The wiring conduit to the gauge must be an approved, flexible type.

2.2.6 Installation With Integral Stilling Well Antenna for Tape and Float Retrofit: Refer to drawing 811541 in Drawing Section at the end of the manual. During final factory testing, each stilling well is assembled and each section is labeled to identify the order in which to connect the pipes and connectors together. Additionally, the overall correct length is confirmed. Complete pre-shipment assembly also enables the orientation of the reflector to be set before mounting on the tank. A small amount of blue thread locker already holds the reflector in position. The programmed datum needs to be the distance from the top of the bell reducer (see drawing 841193) to the bottom of the tank. Add 5 inches to the distance from the top of the NPT pipe inlet to the tank bottom (measurement “H” on drawing 841193). Erroneous levels may be reported if the liquid level drops below the end of the stilling well pipe and the reflector is not positioned properly. Assembly Steps:

1)

Thread the 3” long pipe nipple (490503) into the 1.5” NPT tank entrance fitting. Next, join the 2” to 1.5” pipe reducer (571958) to the nipple. Use appropriate thread sealing methods and tighten these parts to final tightness.

2)

Apply blue thread locker to the threads on the end of the terminal still well pipe marked A2.

3) 4)

Thread still well pipe connector (571953) end marked A2 0.75” onto still well pipe.

5)

Continue assembling pipes in the correct order as determined by the factory markings. Ensure blue thread locker is applied to all thread ends. It is very important to ensure the pipe sections are butted together tightly inside the couplers. It is very important that no gap is present between the pipe sections. Also ensure the couplers have approximately the same thread engagement on the pipe section they are coupling.

6) 7)

Using blue thread locker join still well flange (571952) with the 12” launch section (571955).

8)

Now, thread the radar gauge into the 2” to 1.5” pipe connector using suitable thread sealant. Note: the entire stilling well will rotate as the EVO 2600 housing is turned into the reducer. The final rotational position needs to have the blue mark on the evo 2600 housing facing away from the tank side wall and or any bottom structures in the tank.

At this point during the assembly 2 persons are required to proceed. Lower the section(s) in the tank and have the second person hold it to prevent it from falling into the tank.

Align the blue mark on the radar gauge housing with the blue mark on the flange. Attach the Still well antenna flange to the radar unit with (4) 6-32x5/8” (515958) Screws and lock washers (515560). The blue marks will indicate the open direction of the reflector. The reflector’s opening needs to be rotated away from the tank wall or any other obstructions near the tank bottom.

3. LOCAL INTERFACES 3.1 LOCAL DISPLAYS The evo 2600 is locally programmable via the MCG 2150 IR Calibrator. It also provides a 98x64 pixel graphics LCD display.

3.2 SAFETY GUIDELINES – GENERAL The level display field can show one of the following error codes to indicate device malfunction. Any display panel that shows the gauge level can display these values instead.

Level Field Shows 995.000 996.000 997.000 998.000

Description Internal Error No Target Found Slope Error Distance to Target Greater Than Datum

994.000 IF Signal Level Too Low 4. START-UP AND INITIALIZATION 4.1 REQUIRED PROGRAMMING: STEP 1: Set the DISPLAY UNITS (Function 002) STEP 2: Set the DATUM LEVEL (Function 003) STEP 3: Set the MIN SEARCH LEVEL (Function 004) STEP 4: Set the MAX SEARCH LEVEL (Function 005) STEP 5: Set the SEED LEVEL (Function 006) The Setup Wizard (function 001) for the evo 2600 Radar Gauge was developed to simplify initial startup and calibration. The wizard will step the user through the primary options or functions listed above (only 1-5) that need to be programmed for proper gauge operation and measurement. Even though the programming menu system provides individual functions for setup as shown above, the preferred method to set these values is to use the e.CAL Setup Wizard.

4.2 OVERVIEW: The evo 2600 radar gauge incorporates an infrared communications link that allows programming and internal parameter changes required for commissioning or setup. Programming using this infrared (IR) capability requires a MCG 2150 remote calibrator. The MCG 2150 is a small handheld, battery-operated device, similar to a television remote control, which is used, for menu access, numeric data entry and 5911 Butterfield Road, Hillside, IL, 60162

parameter selection. Designed with safety in mind, the MCG 2150 does not require the 2600’s cover to be removed. The evo 2600 implements a simple IR programming menu system. This is a passwordprotected feature that prevents unauthorized configuration changes to the 2600. Once accessed, the programming menu system enables previewing current settings and changing selected parameters and functions. All user-programming settings are held in non-volatile flash memory

4.3 HOW TO GAIN ACCES TO THE PROGRAMMING MENU FROM THE DISPLAY WITHIN THE EVO 2600 ENCLOSURE: The following is a step-by-step procedure to gain programming menu access.

Step 1:

Aim the MCG 2150 at the infrared receiver from a distance of no greater than 3 feet, then press and hold down the STOP key on the MCG 2150 for a minimum of 3 seconds.

Step 2:

Next press and hold down the ENT key for 1 second then release. The enter pass code screen should appear. This also can take a few seconds to occur. If access was unsuccessful start over with step 1.

Step 3: Key in the pass-code and then press the ENT key. The default value for the User pass-code is 100 and the default supervisor pass-code is 200. These pass-codes are user changeable.

Step 4:

After the correct pass-code is entered, a parameter preview panel will be displayed. The preview panel shown is the last program function changed if the power was not cycled.

Step 5:

Press the UP or DOWN keys on the 2150 to navigate to the desired function. Press ENT to access the function.

Selection list: A selection List allows the user to scroll through a list of values. When the value is displayed that the user wants, press the ENT key. Pressing the UP or DOWN displays the next item in list.

Up and Down:

This entry method allows the user to change a value by pressing the UP to increase or DOWN to decrease the displayed value. When the Correct value is displayed press the ENT key to store the new setting.

Digits:

In Digits entry, the user must press digit keys to enter a value and then press the ENT key to store it. Note the ‘<‘ key moves the cursor one character to the left. Functions requiring digit entries are required to have all digit fields filled with a number. Always enter leading zeros if the number desired is smaller than the prompted entry field.

Exiting a Function or the Program Menu:

Pressing the STOP key from within a function will exit that function returning you to the preview panels. Pressing STOP from within the preview panels will exit the programming menu system altogether.

How to Go to a Function Quickly:

Instead of scrolling to the desired function by pressing the UP or DOWN keys within the preview panels, the user can enter in a function number directly. From any preview panel press ANY number key and a three-digit function number prompt will appear. Enter the desired function number with any leading zeros and press the ENT key to go directly to that function.

4.4.1 Steps to gain access to the MCG 2600 programming menu from the ground level display (GLD): The following is a step-by-step procedure to gain programming access from the ground level display. Step 1: Aim the MCG 2150 remote at the infrared receiver on the GLD from a distance of no greater than 3 feet. Now, press and hold down the STOP key until an “*” character appears in the lower left corner of the GLD display. This can take up to a few seconds. You now have 5 seconds to complete the next step. Step 2: Next, press and hold down the ENT key for a minimum of 2 seconds then release. At this point the “PLEASE WAIT” message will be shown for a short amount of time. Next, the enter pass code screen should appear. If access was unsuccessful start over with step 1.

Step 3: Next, key in the operator, supervisor or service pass-code and then press the ENT key. The default value for the operator pass-code is 100 and the default value for the supervisor pass-code is 200. Three digits must be keyed in. Step 4: After the correct pass-code is entered, a parameter preview panel will be displayed. Step 5: Press the UP or DOWN keys on the 2150 to navigate to the desired function number. Note: The response to all key presses (up, down, number press etc…) can take up to 0.5 seconds to appear on the display after the key is released. Step 6: Pressing STOP from any preview panel will exit programming.

4.4.2 Contrast Adjustment on the Ground level Display: The GLD has a local programming mode that allows the user to change the contrast on the GLD’s display. The following is a step by step procedure to gain access to the contrast function within the GLD. Step 1: Aim the MCG 2150 remote at the infrared receiver on the GLD from a distance of no greater than 3 feet. Now, press and hold down the STOP key until an “*” character appears in the lower left corner of the GLD display. This can take up to a few seconds. You now have 5 seconds to complete the next step. Step 2: Next, press and hold down the RESERVED key for a minimum of 2 seconds then release. At this point the “ACCESS ###” prompt will be shown. Next, enter pass code 100 (unchangeable by user) and press ENT. Step 3: At this point the display will show “01 CONTRAST Cur= ENTER” Press ENT to access the contrast function. Step 4: Use the UP or DOWN keys to adjust the contrast. Press ENT or STOP to exit and save new setting. If no keys are pressed for a short period of time the contrast function will automatically exit. Press STOP is exit the local GLD programming mode.

5. PROGRAMMING FUNCTIONS 5.1 Function 01-e.CAL INTUITIVE SETUP WIZARD: The setup wizard for the evo 2600 radar gauge was developed to simplify initial startup and calibration. The wizard will step the user through the primary options and functions that need to be programmed for proper gauge operation and measurement. The setup wizard prompts the user to set the following five functions. 1. 2. 3. 4. 5.

Display Units Datum Level Minimum Search Level Maximum Search Level Seed Level

Each of the required programming functions presented by e.CAL can be programmed individually and separately from the wizard by navigating to its respective function within the normal programming menu function list. The preferred method to set these values is to use the e.CAL setup wizard. The e.CAL wizard only provides basic setup to configure the evo2600 to gauge the product level. Any other required features and options must be configured and or enabled thru individual functions that are accessed through the programming menu.

5.1.1 Steps To Start The e.CAL Setup Wizard: To start e.CAL you need to gain access to the IR programming menu. The following is a step-by-step procedure to gain access. Step 1: Aim the MCG 2150 infrared remote control at the infrared receiver from a distance of no greater than 3 feet, then press and hold down the STOP key on the MCG 2150 for a minimum of 3 seconds. Step 2: Next press and hold down the ENT key for 1 second then release. The enter pass code screen should appear. This also can take a few seconds to occur. If access was unsuccessful start over with step 1.

Step 3: Key in the supervisor pass-code and then press the ENT key. The default value for the supervisor pass-code is 200. Three digits must be keyed in. Step 4: After the correct pass-code is entered, a parameter preview panel will be displayed. The preview panel shown is the last program function changed if the power was not cycled. Step 5: Press the UP or DOWN keys on the 2150 to navigate to function number 1. Press ENT to launch the setup wizard.

The following panel is shown when the setup wizard starts.

5.1.2 The e.CAL Setup Wizard Prompts: STEP 1: SET THE DISPLAY UNITS: The first e.CAL panel allows the user to set the display/data entry units.

This function allows the user to set the display format for the level and temperature. Press the 1 key to change the units or the 0 key to move to the next prompt. The bottom of the display shows the currently programmed value. Type of Entry: A new format is selected from the selection list via the UP & DOWN keys. Display formats include: Selection FFF-II-16 FFF-II-32 FFF.TTT MMM.MMM



Description Feet Inches and 1/16th’s Feet Inches and 1/32nd’s Feet and 1/1000th’s of feet Meters and Millimeters



This function sets the engineering units for every level entry prompt and data display. When set for MM.MMM, all prompts and displays that show a temperature will be in degrees C, otherwise the temperatures will be in degrees F.



After selecting either yes or no, the wizard will move on to Step 2.

STEP 2: SET THE DATUM LEVEL: The second panel allows the user to set the datum level. The datum level, or top reference level, is usually the height of the mounting flange.

The evo2600 radar gauge measures the distance from the antenna to the product surface. This range is subtracted from the user programmed datum level. This difference is the tank INNAGE and is displayed on the LCD as level in the engineering units as set by the first wizard step. 

It is very important that the datum level be a very accurate measurement.



Pressing the < key will return to the previous step.



Leading zeroes are required when entering a new level.

STEP 3: SET THE MINIMUM SEARCH LEVEL: This function allows the user to set the minimum level reading for the radar gauge. If the level drops below this point, it is ignored and the radar gauge will search for a new level within the range between the minimum search level and the maximum search level. This is useful for ignoring reflections from the tank bottom or from other possible hard obstructions near the bottom.



The minimum search level is automatically set to zero after a new datum is programmed during wizard step 2.









The minimum search level must be less than 10% of the programmed datum.

Fax: (708) 236-6006


Page |22

STEP 4: SET THE MAXIMUM SEARCH LEVEL: This function allows the user to set the maximum level reading for the radar gauge. If a level greater than this value is measured, it is ignored and the radar gauge will search for a new level within the range between minimum search level and the maximum search level. This option is useful for ignoring reflections at the top of stilling wells (flanged-T, ball valve, etc.) and other disruptions above the normal operating level.



The maximum search level is automatically set to 99% of the datum after a new datum is programmed during wizard step 2. If the automatically calculated maximum search level (99% of datum) is greater than the desired maximum fill level of the tank, use the wizard value.









The maximum search level must be greater than 75% of the programmed datum and less than 99% of the programmed datum.

STEP 5: SET THE SEED LEVEL AND CALIBRATE: This function directs the internal tracking algorithm to search for the target echo at the user-entered location (INNAGE level). This function should be used if the evo 2600 has not locked onto the product level but a false echo. It is important the datum level is as accurate as possible.

IMPORTANT – The level entered in as the seed level must be obtained from another accurate measurement source, such as a sight glass or hand gauged measurement. The seed level is entered as INNAGE. 





After seeding a new level, the tracking algorithm in the evo2600 searches for a signal return precisely at the user entered level. If no echo is found that crosses the minimum

Page |23

peak threshold, tracking will continue to search within the range bounded by the minimum and maximum levels. If the radar gauge cannot lock on to the correct level, use the e.WAVE graphical display function to view and determine the location and validity of reflections in the signal spectrum. When a valid reflection is located in the signal spectrum the following panel will show the location of the reflection.

At this point in time the level reported should be very close to the actual level in the tank. The level reported after seeding should be within +/- 12 inches of the actual innage level in the storage vessel. Either a large error in the programmed datum or poor installation resulting in large false echoes can cause tracking to misreport the level. The calibrate function allows the user to "digitally" calibrate the evo 2600 to a level obtained from another accurate measurement source. Calibration in this manor internally calculates an offset, which is added or subtracted to the level. Type of Entry: Digit Entry (Engineering units for entry set by function 02) Default Value: 0 Notes: Entering a value of 128-00-00 for formats of FF-II-16 or 32nds will clear softcal. Entering a value of 128.000 for formats FF.TTT and MM.MMM will clear softcal.

5.2 Function 02-SET UNITS FOR DISPLAY: This function allows the user to set the display format for the level and temperature. Type of Entry: A new format is selected from the selection list via the UP & DOWN keys. Display formats include: Selection FFF-II-16 FFF-II-32 FFF.TTT MMM.MMM

Description Feet Inches and 1/16th’s Feet Inches and 1/32nd’s Feet and 1/1000th’s of feet Meters and Millimeters

Key Usage Notes: This function sets the engineering units for every level entry prompt and data display. When set for MM.MMM, all prompts and displays that show a temperature will be in degrees C, otherwise the temperatures will be in degrees F.

5.3 Function 03-SET THE DATUM LEVEL: This function allows the user to set the top reference for all evo 2600 Radar Gauge measurements. Type of Entry: Digit Entry Default Value: 20-00-00 Feet Note: The SETUP WIZARD prompts the user for setting this value.

5. 4 Function 04-SET THE MINIMUM SEARCH LEVEL: This function allows the user to set the minimum valid level reading for the radar gauge. If a level moves below this value, the level is ignored and the radar gauge will search for a new level within the valid range between Min Search Level and Max Search Level. Useful for ignoring reflections from the bottoms of tanks due to suction, heating coils, supports, etc. Type of Entry: Digit Entry Default Value: 00-00-00 Note: The SETUP WIZARD prompts the user for setting this value.

5.5 Function 05-SET THE MAXIMUM SEARCH LEVEL: This function allows the user to set the maximum valid level reading for the radar gauge. If a level greater than this value is measured, it is ignored and the radar gauge will search for a new level within the valid range between Min Search Level and Max Search Level. This option is useful for ignoring disruptions at the tops of stilling wells (flanged -T, ball valves, etc.) and other disruptions above the normal operating level. Type of Entry: Digit Entry Default Value: 2-00-00 Note: The SETUP WIZARD prompts the user for setting this value

5.6 Function 06-SET THE SEED LEVEL: This function directs the internal tracking algorithm to search for the target echo at the user-entered location (level). This function should be used if the evo 2600 has not locked onto the product level but a false echo. It is important that before the Seed Level is adjusted, that all steps outlined in section 6.1 have been performed. The Datum level must be set correctly prior to setting the Seed Level. IMPORTANT – The level entered in as the seed level must be obtained from another accurate measurement source, such as a sight glass or hand gauged measurement. The seed level is entered as INNAGE. Type of Entry: Digit Entry

5.7 Function 07-LEVEL CALIBRATION: This function allows the user to "digitally" calibrate the evo 2600 to a level obtained from another accurate measurement source. Calibration in this manor internally calculates an offset, which is added or subtracted from the level. Type of Entry: Digit Entry (Engineering units for entry set by function 02) Default Value: 0 Entering a value of 128-00-00 for formats of FF-II-16 will clear softcal. Entering a value of 128.000 for formats FF.TTT and MM.MMM will clear softcal. Important Information: Generally, the software calibration feature (function 006) should only correct the level by a small amount (less than 1 foot). If the level displayed without softcal applied is incorrect by a large amount, this indicates a possible datum entry error or internal tracking has locked onto a false echo. Correct datum measurement and/or try to seed with correct level.

5.8 Function 08-ADJUST THE DISPLAY CONTRAST: This function allows the user to set the contrast for the LCD display in the evo enclosure. Type of Entry: The UP and DOWN keys change the contrast setting. Adjustment range is 0 – 100 percent

5.9 Function 13-SET THE OPERATOR PASSCODE: This function allows the user to change the menu password for entry into the group of user programming functions. Type of Entry: Digit Entry Default Value: 100 (accepts 0 – 999 numeric only)

5.10 Function 20-e.WAVE GRAPHICAL PROFILE: One of the evo 2600's evolutionary features is the new e.WAVE graphical LCD display. In the case of special applications or circumstances, the e.WAVE display provides a graphical profile of the radar signal inside of the tank to ensure there are no unforeseen obstructions or intrusions in level gauging applications. The e.WAVE display allows the radar unit to be fine-tuned to cancel out any obstructions or other disturbances in the tank. To enable the e.WAVE display for analysis use the MCG 2150 remote calibrator to gain access to the programming menu. Use the supervisor or factory access pass code and navigate to function number 20 and press enter to enable the graph. The graph will exit automatically on device malfunction.

Photograph of the e.WAVE Display as Seen On The Ground Level Display

The graph provides a data plot of the signal spectrum sampled by the radar gauge. It shows the relative magnitude and position of the signal return from the product surface as well as any other reflections due to obstructions or other anomalies in the tank. It also gives an indication of spectral purity and signal quality as shown by the sharpness and narrowness of the peak. Graph User Controls and Item Descriptions The graph vertical axis units are magnitude. The numeric values shown are magnitude divided by 100. The dashed line is the minimum peak magnitude as set by function 28. In the picture above the min peak magnitude is programmed to 625. The horizontal axis units are in feet or meters. The areas on the photograph of the display that show 04 and 09 feet are the start and end units for the horizontal axis shown. These values will change as the graph scrolls left and right. Each vertical spectrum bar is 3 pixels wide and is referred to as a bin. Each bin is approximately equal to 61mm or 0.2 feet. The graph provides a somewhat coarse peak location. It is not the intention of the graph for the user to locate peaks in very small measurement units. Each horizontal division on the grid is 1 foot or 0.3048 meters. The photograph shows that the target is about 7.5 feet away from the antenna. The left side of the graph is closer to the antenna. Please remember that all distances related to both types of profiling are measured starting at the antenna (graph left side) going down to the bottom of the tank (graph right side). Located in the lower left corner of the display is a small ramp icon. This icon flashes on and off indicating the radar gauge is sweeping and acquiring the range to target. In the photograph a small letter “M” is shown near the bottom center of the display. This icon indicates the profiling type is set to “MANUAL”. The “A” icon will be shown in place of the “M” when the user has selected “AUTO” as the profiling type.

The “P” icon indicates that the stored profile array is valid. The icon “Px” indicates that the profile array is corrupt and cannot be used to cancel out unwanted reflections. The “PA” icon indicates that profiling is enabled and active. In place of the “PA”, the icon “PS” can be shown when a profile capture and save sequence has been initiated. No symbols shown indicate no capture sequence is active and profiling is disabled. The “OK” icon shows the IF signal magnitude. Values of HH, HI, LO and LL can be seen in this area as well. Before initiating any profiling action, the user should wait until the automatic gain control indicates OK IF status. The “^” character shows what peak the internal surface tracking algorithm has locked onto. Ideally, this location should be under the peak of the product level signal reflection. At locations near the antenna (graph left side) and at some distance (datum level) away from the antenna (graph ride side) small “+” characters will show the min and max search levels. The photograph is a snapshot of the spectrum in the middle of a 20-foot datum, thus the min and max search indicators are not present. The following MCG 2150 single key press commands are active when the graph is shown and when the user has entered programming using the supervisor or higher pass code. Generally, these single key press commands require that the key be held down for about 1 to 1.5 seconds if the ramp icon is flashing.

Auto Profile Details The following graphic shows the spectrum of a typical 20-foot high tank with a small obstruction within the radar emission cone. Auto profiling provides a single, continuous region from the antenna down to the auto level that can dampen or remove obstructions that show up in the measured spectrum. In a case where the magnitude of an obstruction crosses the min peak threshold, it is desirable to dampen or remove its signature from the spectrum to prevent the internal surface tracking algorithm from accidentally locking onto the obstruction and start to track it as the product level. Things You Need To Know: Generally to use auto profiling, the level in the tank should be somewhere near the bottom of the tank and the unit should be tracking the actual level and the IF gain should indicate OK. The actual product level must be below the auto level. In many types of storage vessels the sampled signal spectrum by a radar gauge can sometimes indicate an obstruction when there really isn’t one. This behavior is a result from multi-path microwave reflections inside the tank. Generally, where the multipath reflection appears in the spectrum is a multiple of the distance from the antenna to the actual product surface. Multi-path reflections are dynamic, and will move when the product level moves or maybe even disappear. Only use tank profiling to dampen or remove disturbances created from actual physical obstructions within the radar gauges emission cone. The actual graph display represented by the below graphic would show the “A” (AUTO) icon in the bottom center of the LCD. It also would show that profiling is disabled (missing “PA” icon) because of the obstruction shown in the spectrum below. Product Level Min Peak Magnitude

DATUM = 20 FEET

Before initiating an AUTO profile capture, ensure that the ramp icon has been blinking for a minimum of 10 or more scans, that tracking has locked onto the product level, and the IF level indicates OK. Next, confirm or enter the auto level. Initiate the capture sequence by pressing the number “2” key on the MCG 2150, the gauge will now take a snapshot of the empty tank spectrum from the auto level up to the top of the tank. This data is then saved in the non-volatile profile array and is then used on every subsequent sweep and sample range acquisition for obstruction removal and reduction if profiling is enabled. After the capture and save (registration) sequence is complete, enable profiling (shows “PA” icon). The obstruction will disappear or be significantly reduced from the spectrum on the graph.

A Note About The Tracking Character “^” If the peak that surface tracking has locked onto (“^” character) reaches 10 in magnitude, this indicates that this peak is the largest in the spectrum. If the tracked peak is lower than 10, it means a larger magnitude peak is present somewhere else in the spectrum.

Manual Profile Details Unlike AUTO profiling, MANUAL profiling provides up to 5 regions where the removal or dampening of unwanted reflections is performed. Each region is comprised of two user-entered levels. The first is the upper bound (graph right) and the second is the lower bound (graph left). The upper must always be larger than the lower. Read and understand the auto profiling section because it provides usage details and explanations applicable to the manual mode. Things You Need To Know: Not all regions need to be used and active regions can be different sizes. Unused regions need to be disabled. This is accomplished by setting BOTH the UBound and LBound levels to 0 for its respective region. Do not over-lap regions. Regions do not have to be in numerical order as they appear on the graph. You do not have to start with region #1. Use them in any order or combination. Active regions should reside between the minimum and maximum levels. The current product level can be anywhere within the datum range to perform manual profiling. The tank does not have to be empty or nearly empty to perform a manual profile. To use manual profiling, the profiling type must first be toggled to the manual type (Micon). Use the graph to identify the UBound and LBound levels surrounding the obstruction peak(s). Enter them using the profile level selection menu started by key press 7. The AUTO profile level marker is ignored in manual mode. Markers indicating the region bounds are not shown on the graph.

No character here indicates Tracking LOCKED, a “?” indicates LOST and a “!” indicates SEARCHING. The field showing 14-06-06 above is the level field. This is INNAGE. It’s not the distance from the antenna to the product level. The product level is shown here in the units programmed by the user. This field can also show an error code during device malfunction. The field showing 23 is IF amplifier gain A, the 159 is the IF gain B and the 89 is an 8-bit scan counter incremented every sweep. The 21567 field shows the magnitude of the sampled IF frequency. The internal AGC control algorithm automatically adjusts gains A&B to keep this value around 22000 counts. The 1000 field is the normalized track bin peak. When equal to 1000, this indicates the spectral peak magnitude that tracking has locked on is the largest peak in the bin array. When this value is less than 1000, it means a larger peak is present elsewhere in the array. The 010, 030 and 050 fields show the track min bin, the peak bin and the track max bin respectively.

The 001, 101 and 000 fields show the min search bin, the max search bin and the last value is always 0. The bottom line shows three error counters. The first is error count #1 and it is incremented when the sweep and sample command issued from the MSP to the DSP has failed. Error count #2 is incremented when the radar processing command has failed. The error count #3 indicates a checksum error on data downloaded from the DSP. Normally none of these counters should be changing.

This applies to most communication protocols. Most applications of the evo 2600 require this parameter set to 0. Type of Entry: Digit Entry Default Value: 0 (accepts 0 – 999 numeric only) Important Usage Notes for MODBUS USAGE ONLY: When the evo 2600 is configured for the MODBUS protocol, the polling master usually requires a minimum delay of 3.5 character times before the evo 2600 begins to transmit its message frame in response to a register query. When this “respond delay” function is programmed to 0 (AUTO MODE), the evo 2600 automatically delays its transmission to provide the Baud Delay in required 3.5 character idle line time as dictated by Rate milliseconds MODBUS specifications. The currently selected 300 128 baud rate controls the AUTO delay duration. The 1200 32 table below shows the AUTO delays for each of the 2400 16 baud rates that the evo 2600 can be programmed 4800 8 for. The user cannot change the AUTO delay durations. 9600 4 OVER-RIDE of AUTO mode: If a non-zero value is programmed into the “respond delay” function, the AUTO mode will be cancelled and the programmed respond delay will be used instead. EXERCISE GREAT CARE when canceling AUTO mode. Some MODBUS masters can tolerate a slave beginning its transmission without having a silent time greater than 3.5 characters present on the network after the master’s query. The evo 2600 allows the user to cancel AUTO mode and program the respond delay to a value (non-zero) well below the 3.5 character silence criteria or to a longer value to account for latency found in some systems. For polling systems that might have this relaxed capability, it is recommended to minimize the respond delay to maximize the data-polling rate.

7. MAINTENANCE

Warning! Remove power to the gauge before doing any maintenance. Replace the desiccant yearly. When changing the desiccant, check the inside of the gauge for water damage. If water damage is found, locate fault and correct. 7.1 L&J MAINTENANCE AND REPAIR PROGRAM: The L&J Engineering maintenance and repair program for the L&J Systems consists of both routine and preventive maintenance that, if performed properly, provide years of trouble free tank gauging. After completing a training session, the end user will be able to perform all routine and preventive maintenance. All L&J Engineering Systems provide self-checking diagnostics to alert the user of potential problems that can cause downtime. The diagnostics are incorporated into all of the field devices (gauges, transmitters, RTU’s, remote displays, etc.) and the main computer system. Field units are al l microprocessor-based. The microprocessor is programmed to perform the basic functions of measurement and control as well as to check all its internal devices to ensure that data being collected is correct. If the microprocessor detects any data within its measuring and control devices that are incorrect, it immediately begins displaying an error code on the local indicator (when available) and sends the error code to the main computer system. If the error is severe enough that continued use would affect operations, the device will disable itself or the computer will stop interrogating it.

Channel #1 Analog Output - Process Level The 2-wire 4-20ma current loop is output on TB2 terminals 5 and 6. Terminal 6 is the LOOP + and terminal 5 is LOOP -. Power required is 18-36 VDC at the transmitter terminals. This is the only output from this transmitter, representing the process level measurement and scaled according to the ZERO (PV Lower Range, function 44) and SPAN (PV Upper Range, function 45) settings. This output corresponds to the primary variable (PV). A fixed output current of 22.00 milliamps indicates device malfunction when loop signaling is enabled.

Device Variables: The evo 2600 does not support or expose any device variables. Re-mapping is not supported.

Dynamic Variables: The evo 2600 supports 2 dynamic variables, the PV and SV. The TV and QV are not supported and return NaN when queried. Re-mapping is not supported. The PV = Level and the SV = Optional Temperature. SV will return as 999.9 when not supported or during RTD malfunction.

Device Status: The EVO 2600 field device status is contained in the second data byte in a slave to master frame. This status byte indicates the current operating status for the device and is not associated with the completion of any command.

Required Programming Using MCG 2150 IR Remote: The evo 2600 MAX Encoder Transmitter requires the MCG 2150 infrared remote to program functions that are required for HART operation. This section only explains the programming functions related to HART communications.

Function 02 – SET UNITS FOR DISPLAY: The user can set any of these display formats with the MCG 2150: FFF-II-16 = Feet Inches and 1/16th’s (English) FFF-II-32 = Feet Inches and 1/32nd’s (English) FFF.TTT = Feet and 1/1000th’s of feet (English) HART Unit Code 44 MMM.MMM = Meters and Millimeters (Metric) HART Unit Code 45 Note: The evo 2600 supports 4 LCD display/data entry formats. All 4 of these are settable using the MCG 2150. Remote HART configuration is ONLY allowed to use the unit codes of 44 or 45. When the LCD display/user entry formats have been configured for any of the 3 English display units using the MCG 2150 and a HART master sets PV units to “feet”, the display will automatically reprogram the format for feet and thousandths.

Function 22 – SET ADDRESS: When configured for HART communications, the evo 2600 will accept polling addresses of 0 to 63 inclusive. For HART single drop transmitters this address is normally set to 0. For HART multi drop systems the address is set for values of 1-63. Notes: When a non-zero address is set locally using the MCG 2150, the analog output does not disable loop signaling. On the contrary, if a REV 5 HART master issues the write polling address command with a non-zero address, the evo 2600 MAX will automatically disable loop current signaling and the field device status bit 3 (mask 0x08) will be set indicating “loop current fixed”. The analog output is forced to 4.000 milliamps in this condition. The user can override this action see function 48.

Function 23 – SET BAUD RATE: This setting MUST be set to 1200 baud for HART Communications.

Function 24 – SET PARITY: This setting MUST be set to ODD parity for HART Communications.

Function 44 – SET THE ANALOG OUTPUT ZERO LEVEL:



Phone: (708) 236-6000

Fax: (708) 236-6006


Page |45

This function allows the user to set the Analog#1 ZERO-scale output level. This programming function is also known as the Lower Range Value or LRV. Note: The LRV MUST be lower than the URV. This setting is also changeable from a remote HART master using command 35.

Function 45 – SET THE ANALOG OUTPUT SPAN VALUE: This function allows the user to set the Analog#1 SPAN-scale output level. This programming function is also known as the Upper Range Value or URV. Note: The URV MUST be greater than the LRV. This setting is also changeable from a remote HART master using command 35.

Function 48 – CONFIGURE THE ANALOG OUTPUT MODE: This function enables the user to continuously FORCE the loop current signaling to 4.000 milliamps. When in FIXED MODE, the analog output is frozen at 4.0 milliamps and DOES NOT FOLLOW THE ENCODER LEVEL! Two selections are available under this function: 1) TRACKS LEVEL (Normally set when HART SINGLE DROP, Polling address=0) 2) FIXED (Normally set when HART MULTI DROP, Polling address<>0) The HART device status bit 3 (mask 0x08) will be set which indicates “loop current fixed” when this parameter is set to FIXED. This function allows the user to override the action of a remote HART master setting a non zero address (REV 5 HART multidrop) which automatically would have set the analog output into fixed mode.

CAUTION! FOR HART SINGLE DROP MODE: CHANGING THIS SETTING CAN CAUSE SERIOUS PROBLEMS FOR PROCESESS DRIVEN AND CONTROLLED FROM THIS OUTPUT! WHEN SET TO FIXED MODE, A FAILURE WILL NOT CAUSE THE ANALOG OUTPUT TO DRIVE 22.00 MILLIAMPS. THE HART MASTER WILL HAVE TO POLL THE DEVICE STATUS BITS TO CHECK FOR DEVICE FAILURES.

Universal Commands: The evo 2600 supports all HART® Revision 6.0 Universal Commands per HCF_SPEC-127. These commands are summarized below including any applicable usage notes for the evo 2600. All commands described as “write” are write protected via a jumper. Consult document HCF_SPEC-127 for additional information about the following commands. Command #0: Read Unique Identifier Command #1: Read Primary Variable Note: The primary variable (i.e. PV) is Product Level (Vessel/Tank INNAGE). Command #2: Read Loop Current and Percent of Range Command #3: Read Dynamic Variables and Loop Current Note: This command returns PV and SV for a total of 14 response data bytes. See command #2 note pertaining to the loop current. Command #6: Write Polling Address Note: Polling addresses 0 – 63 inclusive are supported. HART® revision 5 compatibility is supported in the following ways: When the evo 2600 receives this command with a single data byte, it assumes a HART® revision 5 master is attempting to write data. Per revision 5, if the polling address being written is zero, the evo 2600 will enable current signaling (analog output follows process), if the polling address being written is non-zero, current signaling will be disabled and the field device status bit 3 (mask 0x08) will be set. Command #7: Read Loop Configuration Command #8: Read Dynamic Variable Classifications Note: The evo 2600 only supports the PV and SV. PV classification returns as “Length”. SV as “Temperature” The classifications for variables TV and QV return as “250” not used. Command #9: Read Device Variables with Status Note: The evo 2600 does not support any device variables. Thus, when device variable 0 is requested, the PV is returned. Command #11: Read Unique Identifier Associated with Tag Command #12: Read Message Command #13: Read Tag, Descriptor and Date Command #14: Read Primary Variable Transducer Information Command #15: Read Device Information Command #16: Read Final Assembly Number Command #17: Write Message Command #18: Write Tag, Descriptor and Date

10. MODBUS COMMUNICATIONS OPTION

GENERAL The evo 2600 implements the "Binary RTU Protocol" as described in "GOULD MODICON MODBUS PROTOCOL" document "PI-MBUS300revF".

SUPPORTED COMMANDS: FUNCTION 03 - READ HOLDING REGISTERS (16 Registers MAXIMUM) FUNCTION 04 - READ INPUT REGISTERS (16 Registers MAXIMUM) If the evo 2600 is programmed to display the level in English units, the level and temperature registers will be in English Units. The level register contains an unsigned integer representing total thirty seconds of an inch. The temperature register contains a signed integer representing total 1/10ths of degrees. If the evo 2600 is programmed to display the level as meters, the level and temperature registers will be metric Units. See register 30005/40005 for units flag bit. The data is populated into these registers as follows:

Register 30001/40001 - Product Level For example: evo 2600 display shows LEVEL = 41-10-05 <- Display format set to FF-II-16 30001/40001 = 0x3ECA 0x3ECA hex = 16074 decimal 16074 / 384 = 41.859375 feet (1 foot = 384 thirty seconds) A value of 0xFF00 hex (170 Feet) indicates a Level Error and is to be considered invalid. If the Units are Metric: For example: evo 2600 display shows LEVEL = 16.074 <- Display format set to MM.MMM 30001/40001 = 0x3ECA 0x3ECA hex = 16074 decimal = 16,074 Millimeters 16074 / 1000 = 16.074 Meters A value of 0xFF00 hex (170 meters indicates a Level Error and is to be considered invalid.
