Chapter 1 System Description 1
The Engine Safety System, DPS 2100 In parallel to the Bridge Manoeuvring System, DMS, the Engine Safety System, DPS, is installed. It monitors, controls and protects the propulsion plant absolutely independent from the DMS. It protects the plant against inadmissible operating states in that way, that an alarm is not created until one of the limit values are exceeded. All limits are set to a value that poses no danger to the propulsion engine, if they are exceeded. The alarms are optically indicated on the assigned Operating Panel, ECR, acoustically by buzzer. For an overview see Fig. 1 - 1.
Fig. 1 - 1, Overview Engine Safety System The limit values, delay times and consequences of the individual measuring points are written in the Parametertable (pls. refer to chapter 7). The parameters are part of the

software and stored on the DZM module. In case of exceeding very important, or at least dangerous limit values as high cooling water temperature, low lub oil pressure etc., the DPS will not only activate an acoustical- and optical alarm. In these cases the Engine Safety System, DPS, will send two signals to the Bridge Manoeuvring System: - a SHUT DOWN request inclusive a SHUT DOWN alarm The alarm is every time active before the real action is carried out by the DPS and in parallel by the DMS. The hardware configuration consists of: -
a group of electronic modules installed in the Propulsion Control Cabinet, PCC
-
the Operating Panel, located in the ECR
-
the illuminated EMERGENCY STOP pushbuttons, located in each wing console, on the bridge console, on the ECR console and on the local panel in the engine room
1.1 The Electronic Modules The electronic components basically consists of three electronic modules. They are also located inside the Propulsion Control Cabinet, PCC. The electronic modules are:
-
the Speedrelay Module, DZM 402 This module is the central module of the DPS and contains the software for the DPS 2100. It is also responsible for speed sensing and overspeed monitoring.
-
the Input / Output Module, IOM 402 This module has 16 digital inputs and 12 solid state outputs. The in- and outputs are designed for line break monitoring.

1.3 Stop by Shut Down criteria For all shut down criteria required by the engines manufacturer single inputs are provided by the DPS 2100. If one or more shut down criteria become active, the shut down of the engine is carried out by energizing the stop valves for the different cylinder groups simultaneously. The general arrangement is shown in Fig. 1 - 3.
1.4 EMERGENCY STOP (push buttons and overspeed) For the manual release of an Emergency Stop of the propulsion engine several push buttons are available as described above. The manual released Emergency Stop is hardwired from one contact of each push button to the solenoid. A second contact is wired to the electronic modules as an input and rerouted to the solenoid via an output. An automatic release of an Emergency Stop is carried out, if overspeed is detected by the DPS 2100. The overspeed output contact is set, which also is directly wired to the emergency stop solenoid.

1.5 Engine speed sensing 1.5.1
Measuring principle Impulse transmitters will sense teeth on the flywheel or on an engine internal toothwheel. Two sensors with a 90 degrees (electrical) phase shift are necessary for calculation of speed and sense of rotation. For the frequency range used for slow as well as medium speed engines the time interval between impulses shall be used as the basis for calculation of speed as well as direction. Both sensors are used for calculation of speed such that in case one sensor fails no interruption of speed calculation will occur. The mechanical arrangement is shown in Fig. 1 - 5.
A = Distance from tooth to tooth a = 1/4 * A (+/- 20%) B = Adjustable from 1 to 4 mm

Sensor supervision As a standard 3-wire proximity sensors will be used where monitoring for signal line wire breakage is difficult. Therefore, the two sensors shall monitor each other crosswise for missing impulses, additionally a plausibility check shall monitor for loss of impulses when there should be impulses according to operating condition of engine. Margins for supervision to be sufficient high to prevent alarm during non-continuous engine shaft movement e.g. before stopping. Sensor failure to be alarmed. If no backup from overspeed switch is provided, speed sensor failure will cause a general fault with condition "freeze".
1.5.3
Fast filtering The Speed signal is represented by the mean value of the engine speed for one ignition. Therefore, the time sum for 360 deg / number of cylinder is used for the calculation of the speed signal.
1.5.4
One turn counter A one-turn signal is necessary for slow turning purposes and for stroke counting. Signal to come on after a complete turn continuously in one direction.

Chapter 2 Functions and Indications 2
Functions and Indications The DPS 2100 provides the function -
Shutdown
The input channelse on the central module DZM 402 for the speed measurement via pick up's are fixed. Also the output channels for speed indication and emergency stop on overspeed are fixed. The remaining input channels on the IOM 402 modules are freely configurable for shutdown via parameter (Please. refer to the parameter table).
On occurrence of a Shutdown criterion, the particular function becomes active, taking the parameter setting for the input channel into account. On principle, optical and acoustic signals are output in case the engine safety system DPS responds. Operation and indication are effected via the Operating Panel in the ECR and, contrary to this, via illuminated pushbuttons and LED displays in the engine room. The optical alarms as well as system conditions are simultaneously displayed at all places of indication (bridge, ECR, engine room ). The acoustic alarms are given only at the place of indication from which the ship is operated (e.g. operation from the bridge). This also applies to the acknowledgement of alarm signals as well as to control functions ìCancelî and ìResetî. When there are no system faults and alarms respectively available at the system, then the following view appears on the display of the Operating Panel as shown in Fig 2 - 1.

Automatic Shutdown In case of an automatic shutdown the propulsion system is immediately stopped. The signal acts directly on the shutdown system of the main engine. All control elements and indications for the automatic shutdown are arranged on the bridge, in the ECR and in the engine room.
2.1.1
Shutdown If a shutdown criterion occurs, first of all a pre-alarm is activated. The delay time for the pre-alarm can be adjusted via parameter. If the pre-alarm is activated, an acoustic and optical alarm is given on the ECR panel and in the engine room. With the pre-alarm activation, the delay time (e.g. 8 sec., set via parameter) for the shutdown intervention starts to count down. On the display
Shutdown in 8 s appears in the third line The cause for the initiation e.g.
ìCam Shaft Lub.Oil Press. low appears in the fourth line. Indication ìShutdown in 8 s means, that the shutdown will be active in 8 seconds. The

Alarm- Shutdown can be activated, as an option. The horn signal is reset on the Operating Panel by activating the key for acoustic acknowledge. Optically acknowledgement is possible in the alarm list only. By activating key for optical acknowledge the alarm is optically acknowledged. In doing so, LED ALARM changes into current brightness steady light. After expiry of the shutdown delay time, the shutdown process is started and optically indicated on the bridge panel , on the ECR panel and in the engine room.

Manual Emergency Stop In addition to the automatic shutdown there are emergency stop pushbuttons for the manual shutdown on the bridge, in the ECR and in the engine room. In order to avoid any unintended activation the pushbuttons are equipped with cover plates. The classification societies require an independent shutdown initiation. For that reason the emergency stop pushbutton contains two independent switches. One stop signal acting directly on the stop valve and the other stop signal going into the safety system. The emergency stop is indicated on the Operating Panel in plain text as shown in Fig 2 13. In addition an alarm is given and the LED ALARM is flashing with full brightness, the LED in key panel ALARM LIST changes into red steady light. The LED in the
SHUTD. ACTIVE - key is illuminated. The initiation places for manual emergency stop are indicated in the alarm list. When the emergency stop is removed, the shutdown has to be reset as described before.
Alarm Indication and acknowledgement The Alarms are divided into the two groups
Engine faults, leading to shutdown and
System faults, e.g. line breaks, module failure

Speed Indication Beside the speed indication at the Operating Panel the system provides two ± 10V analogue outputs for external speed indication via instruments. The first output is switched to three connection points on terminals. If the DZM 402 fails, the Speed Indication is switched over to the indication signal coming from the DMS as an input. This redundance guarantees a high availability of the Speed Indication at all relevant places. The second output is also led to terminals, directly as voltage output (± 10V) and converted - as current output (4 - 20 mA). In addition to the above described speed indication, the speed is indicated directly via a 4-digit display at the DZM 402. Negative values indicate astern running. The general configuration of the Speed Indication is shown in Fig. 2 - 16. The arrangement of indication instruments is shown in Fig. 2 - 17 as an example.

The DZM402 module is mainly intended for applications where a quick speed measurement by means of pick-ups must be realized, e.g. the safety system for large diesel or for main engine control systems. The DZM402 assembly is a central unit with 4 galvanically decoupled digital inputs. Two inputs are designated for pick-ups. The measured speed can be displayed on ±10V instruments via 2 analog outputs. One output can also drive a current of 0(4)-20mA. 4 relays and 2 solid-state relays are available for messages and control systems. 16 LEDs as status signals can be used as well. The module has two galvanically decoupled interfaces (RS485) for the purposes of networking the assemblies as well as one for testing or extending (TTL signals). There are four keys and a 4-digit display for parameter inputs and operational status displays. The assembly can be extended by a maximum of another four digital input/output modules and one analog input module (AEM402). It is also possible to connect two SEM402 assemblies with two RS485/ 422 interfaces each to the analog bus. The module is organized by a single-chip microcontroller (HC11). There are 2K EEPROM, a maximum of 32K RAM and a maximum of 72kbytes flash EPROM available for the program. The controller organizes the interface and the extension busses. The digital inputs are filtered and transmitted to the master via the interface upon request. The module can be extended by 1 interface modules,

Chapter 5 Maintenance and Trouble Shooting (on Board) 5
Introduction The Maintenance and Trouble Shooting instructions are based on the alarms, indicated at the Operating Panel. In the following the alarms, the possible reason for the alarm and the recommended actions are described.
5.1 Alarms 5.1.1 OVERSPEED The actual speed has exceeded the overspeed limit. The output contact OVERSPEED SHUT DOWN is closed as long as overspeed is sensed and opened with an adjustable delay (normally 10 sec). If the DMS detects overspeed alone or prior to the DPS, the DPS will alarm line break of the emergency stop valve.
Reason The DPS detects overspeed -
because the engine speed really exceeded overspeed limit
-
because the parameter for overspeed limit in the DPS is set to a lower value as required
Recommended Action: -
Check parameter setting for the Overspeed limit in the DPS.

5.1.2 PICK UP 1 FAULT/PICK UP 2 FAULT The alarms indicate -
missing pulses from speed sensor 1
-
missing pulses from speed sensor 2
If one sensor fails, the DPS works on the other speed sensor alone.
Recommended Action: -
Check the distance of the alarmed speed sensor (pick-up) to the teeth of the flywheel.
5.1.3 PICK UP 1 WB The alarm indicates a line break of speed sensor 1 signal
Recommended Action: -
Check the cabling from the pick-up to the DZM402 of the DPS
-
Check the jumper setting of X19 for npn/pnp pick-up on the DZM402
5.1.4 PICK UP 2 WB The alarm indicates a line break of speed sensor 2 signal
Recommended Action: -
Check the cabling from the pick-up to the DZM402 of the DPS
-
Check the jumper setting of X19 for npn/pnp pick-up on the DZM402

5.1.5 IOM/N Xn.m WB The alarm indicates a line break at a digital input or output on module IOM402, where -
N assigns the number of the respective IOM-module
-
n assigns the terminal block on the IOM and
-
m assigns the terminal number on the terminal block
Examples: IOM/1 X5.2 indicates a line break for the first IOM402 on digital output terminal block X5, terminal number 2. For the output destination (valve coil) pls. refer to the ships related wiring diagrams. IOM/1 X3.5 indicates a line break for the first IOM402 on digital input terminal block X3, terminal number 5. For the input (sensor contact, pushbutton) pls. refer to the ships related wiring diagrams. The reason for the alarm can be: -
a real line break at the assigned input/output
-
nothing is connected to the input, but the line break monitoring is released by parameter setting. The outputs required by system configuration are always monitored for line break.
Recommended Action: -
Check the cabling from the sensor contact or the pushbutton to the input
-
Check the cabling from the output to the respective destination
-
Check the parametersetting for the assigned input

Entering Passwords
On principle the adjustment of parameters is blocked for unauthorized persons. Three password levels in this system are provided: -
Service Password For changing critical parameter values, e.g. the parameters for engine speed, the operator must know the Service Password. The Service Password should be known by commissioning personnel only. The Service Password also releases the parameters where the User Password or the Expert Password has to be known. The Service Password cannot be changed.
-
Expert Password If the Expert Password is known, the operator can change critical parameter values, e.g. the parameter values of shutdown. The Expert Password also releases the parameters where the User Password has to be known. The Expert Password can be changed by setting parameter number 4 to a value between 0000 and 9999. To do this, the Expert Password or the Service Password has to be known.
-
User Password If the User Password is known ,the operator can change non critical parameter values. The User Password can be changed by setting parameter number 5 to a value between 0000 and 9999. To do this, the User Password, the Expert Password or the Service Password has to be known.
To release a selected parameter for value setting, the key Edit
has to be pressed. If the adjustment of parameters is not released, the operator is requested to enter the correct password. The kind of request Service Password :

Note : The passwords always consist of four digits, i.e. also leading zeros have to be input, e.g. "0035". The input password releases parameter setting for a preset time, set in parameter Nr. 6. With every action during the parameter adjustment session, the time is set to this value. If no intervention takes place or the parameter adjust is left, the time is counted down. After expiry of the time, the release to change parameter values is cancelled. The next attempt to change parameters results in a password request on the level for the particular parameter. If the password for a low level parameter is set, and a parameter on a higher level is selected to change, the password for the higher level is requested.

Changing of Parameter Values
NOTE: Because the program uses the RAM-value, a change of a parameter effect s function immediately. Therefore changes only should be made on stopped engine. If the engine is running, changes should be made step by step with small changes on each step. To open a selected parameter for value setting, the key Edit
has to be pressed. If the adjustment of parameters is not released, the operator is requested to enter the correct password as described in part 6.1.2.1. After input of the correct password the selected parameter is displayed again. To open the parameter for value changing, the " EDIT" - key has to be activated again. Following this, in the display the cursor is indicated below the least significant digit of the parameter value. There are two possibilities to change the parameter value:
1. By activating the cursor keys " / " the selected digit is increased/decreased one by one with every key stroke. At a decade overflow/underflow the next higher digit is increased/decreased by one, e.g. 0 7 - 08 - 09 - 10 - 11 ... 10 - 09 - 08 ... To select the digit to be changed within the value display, use the
/ - keys to
shift the cursor to the desired digit. 2. By numerical setting of parameter value. To set the value, first the "0" - key has to be pressed, to open the value for changing. The actual parameter value is replaced by the cursor. Afterwards the desired value has to be set by using the alpha numerical keys (0 - 9). A parameter value can only be set within fixed margins. The upper and lower limit are recorded in the program and documented in the parameter list. If the value is set to more than "Upper Limit", the parameter value is set to "Upper Limit". If the value is set to less than "Lower Limit", the parameter value is set to "Lower Limit".

When the desired parameter value has been input, this must be completed by activating the key "ENT" to save the new value. By pressing the " ESC" - key the new parameter value entered is not accepted. The old value remains and display changes to "Old Value". Because the old parameter value (EEPROM) and the new parameter value (RAM) are displayed continuously during the parameter adjustment session, the operator is always informed about the old parameter setting and the change he made. To leave the parameter adjust, the " ESC" - key has to be pressed. Following this, the menu is displayed again as shown in Fig. 6 - 1. All changed parameters are now recorded in the EEPROM, in order to keep them even if the power supply is switched off.
NOTE: If the parameter adjustment session is not completed by pressing the "ESC" key, the session is automatically completed after expiry of the timeout, set by parameter Nr. 6. In this case also the menu is displayed and the changed parameters are written to the EEPROM.
This is also valid, if a parameter change was not completed by activating the "ENT" key, and the parameter was still opened for changing! The display at the parameter adjustment procedure is shown in Fig. 6 - 5.
