AC Traction Motor The AC traction motor is a three-phase AC induction motor. The motor does not include motor brushes or a commutator. An AC induction motor oper ates on three-phase AC power provided directly by the controller. The motor speed is control led by the motor controller and can be cha nged by the frequency of the AC power supplied to the motor. A speed sensor has been built into one of the motor bearings which provides feedback to the motor controller allowing software to continually monitor motor direction and revolutions per minute (RPM). Using this feedback system, the AC motor control can provide much better vehicle top speed control than the older DC SEM systems.

Controller The motor controller conver ts DC power from the truck battery to three-phase AC power at the frequencies and currents necessary to drive the trac tion motor. A bearing in the traction motor provides feedback of speed, rotation direction, and temperature directly to the motor controller.

The motor controller receives power through the main contactor which is controlled by the key switch. The controller receives inputs from the control handle and the hand rail switches to control lift truck functions. NOTE: There are no serviceable parts in the motor controller. No attem pt shoul d be made to open repair, or otherwise modi fy the cont roller. Doing so may damage the controller and/or lift truck. Removing the cover from the controller will void the warranty.

Service PC Connection The lift truck is equipped with a connection point to connect a laptop computer with ETACC software installed. This connection can be used to adjust certain lift truck parameters and to assist with troubleshooting the lift truck.

Parameters GENERAL

Parameters can be adjusted through the dash display. The factory default values listed in Table 1 are

A parameter is a measurement or a setting that defines a lift truck function. A specific functio n parameter works with other function parameters to control the operation of the lift truck.

the recommended settings for new units. These settings will give satisfactory performance for most applications.

WARNING The parameter for each function has a value range so the motor controller can be used on different models of lif t trucks. This variati on is needed for lift trucks of different sized and operation voltag es. Adjustment of a function to the wrong number value for your lift truck model can cause the truck to operate diff erently than normal. This differe nt operation of the truck can cause an injury. NOTE: Table 1 shows the factory default setting for each parameter that is adjustable by the user.

WARNING If any of the parameter values are changed, the operators must be told the lift truck will operate differently. NEVER adjust any of the following parameters without using the procedures and setting s given in this section. Function Parameter Descriptions in this section contains descriptions for the different parameters. These parameters can also be accessed using the ETACC PC software.

Parameter Description PARAMETERS WARNING If any of the parameter values are changed, the operators must be told the lift truck will operate differently. NEVER adjust any of the following parameters without using the procedures and settings given in this section. Parameters can be adjusted through the dash display LCD. These parameters can also be accessed using the ETACC PC software.

Extended Shift This parameter when on, will reduce traction performance by 15% to provide extended battery shift life. The parameter may be set to the OFF or ON condition.

Walk Speed (Both Directio ns) This parameter sets the maximum truck speed for forward and reverse directions when the truck is in “Walk” mode. Increasing the setting will incr ease the truck speed. Decreas ing the setting will decrease truck speed.

Hi Speed (FWD) This parameter sets the maximum forward speed of the lift truck whe n the truck is in “Ride” mode. Increasing the setting increases the speed. Decreasing the setting will decrease the speed.

Hi Speed (REV) This parameter sets the maximum reverse speed of the lift truck whe n the truck is in “Ride” mode. Increasing the setting increases the speed. Decreasing the setting will decrease the speed.

ParameterDescription

Minimum Acceleration This parameter sets the minimum acceleration rate of the lift truck when the truck is in traveling at the lowest throttle. Increasing the setting increases the minimum rate of acceleration. Decreasing the setting will decrease the minimum rate of acceleration.

Maximum Acceleration This parameter sets the maximum accelera tion rate of the lift truck when the truck is traveling at maximum throttle. Increasing the setting increase the maximum rate of acce leration. Decreasing thes setting will decrease the maximum rate of acceleration.

Plugging This parameter contr ols the maximum rate of deceleration when the speed control is fully moved to the opposite direction from the direction of travel while the truck is moving . Increasing this setti ng will increase the rate of deceleration. Decreasing the setting will reduce the rate of deceleration.

ADS-Neutral This parameter controls the rate of deceleration when the speed control is returned to the neutral position and the ADS-Throttle parameter is set above 1. Setting the value at 1 will res ult in no effec t on the rate of deceleration; the truck will coast until it comes to a stop. Increasing the valu e will incr ease the rate of decel eration. Decreasing the value will decrease the rate of deceleration.

ADS-Throttle This parameter controls the rate of deceleration when the speed control is partially reduced and the ADS-Throttle parameter is set above 1. Setting the value at 1 will result in no effect on the rate of deceleration; the truck will coast until it reaches the lower throttle speed. Increasing the value will increase the rate of decel eration. Decreasing the value will decrease the rate of deceleration.

Pick Acceleration This parameter controls the rate of acceleration when the coast control switc h is activated. Increasing the value will increase the rate of acceleration.

2200SRM1352

Decreasing the value will decrease the rate of acceleration.

Pick Deceleration This parameter controls the rate of deceleration when the coast cont rol switch is relea sed. Increasing the value will increase the rate of deceleration. Decreasing the value will decrease the rate of deceleration. Setting the value at 1 will result in no effect on the rate of deceleration; the truck will coast until it comes to a stop.

Battery Full Voltage This is the battery voltage in millivolts at which the battery is considered fully charge d. Increasing the setting increases the voltage. Decreasing the setting reduces the voltage.

Lift Interrupt This is the battery voltage in millivolts at which the battery is considered 80% discharged. Increasing the setting increases the voltage. Decreasing the setting reduces the voltage.

Service Hour Reminder This parameter initiates a reminder when the hourmeter reaches a preset point indicating the lift truck is due to be servi ced. Within this menu, you can reset the Service Hour Reminder, change the service inter val hours, and turn the functi on ON or OFF. The normal factory default setting for the Service Hour Reminder is OFF and must be changed to ON for the function to be active. When the Service Hour Reminder is ON, the dash display will display a one-time message to the operator when the preset hourmeter reading has been reached. The lift truck will continue to operate normally until the hourmeter reaches 20 hours past the preset service interval. At this time the lift truck function speeds will be reduced until the Servic e Hour Reminder has been reset . The lift truck should be serviced and the parameter reset to the next hourmeter reading when service is due.

Troubleshooting

Troubleshooting GENERAL The controllers are sealed units with no serviceable components. Troubleshooting is usually limited to accessing status codes and following the diagnostic procedures listed in the status code charts. Use standard testing procedures to verify inputs and outputs when necessary.

CAUTION Never attempt to probe through the back of the connector plugs of the motor controller. The plug s are speci al seal ed plugs . Probing through the back of the plugs will destroy the seal and can caus e a short circu it. If a circuit must be tested for voltage, check for voltage at an amp-type plug, a switch, or a component. If a circuit is suspect, check the circuit for continuity from the front (pin end) of the plug. Standard probes are too large to be inserted into the center of the female pins (sockets) of the specia l sealed plugs and can expand the pins. Expanded pins will not provide goo d connections once the plug is reconnected. The connectors are shaped to allow the insertion of a flat blade screwdriver into the connector. After inserting the screwdriver into the attach probes with alligator clips toconnector, the shank of the screw driver to o btain readings . An additional method would be to use a breakout kit. If the controller detects an issue, a status code is displayed on the display panel. Once the status code number is obtained, follow the procedures outlined in the status code charts of this manual to determine the problem. NOTE: Due to the interaction of the controller with all lift truck functions, almo st any status code or controller fault could be caused by an internal failure of the controller. After all other status code procedures have been followed and no problem is found, the controller should be replaced as the last option to correct the problem. Tools and test equipment required are: • Clip Leads • Digital Multimeter (20,000 ohms per volt) • Basic Hand Tools

Check resistance on the proper scale from frame to power and controller terminals. Resistance of less than 20,000 ohms can cause misleading symptoms. Resistance of less than 1000 ohms indicates a short and should be corrected immediately. The on-board diagnostic system employed on this lift truck can assist in the troubles hooting process. Read and be familiar with the instructions for accessing and using the dash display diagnostic system. Prior to troubleshooting systems and components on this lift truck, ensure the battery is the correct voltage and is fully charged. Make sure the battery connector contacts are clean of corrosions and the battery polarity within the connector is correct. Inspect to ensure all fuses are correct and have not failed. Ensure the key switch is in the ON position when making voltage checks or checking the operator of a component. Many faults noted by lift truck systems are the result of loose wiring connection s and/or broken or shorted wiring within the lift truck. Begin the troublesh ooting process by carefully inspecting the wiring involving the device or devices noted by the on-board diagnostics system.

STATUS CODES Make sure the parameter values are correct for your lift truck to ensure the trouble is no t just an incorrect setting. See function settings to set the correc t parameter values. If there is no status code display and the lift truck does not operate correctly, there may be a fault in the controller. The status codes are numbers for malfunction or lift truck operation that are not correct and that the controller can sense . The contr oller will indic ate this code number on the LCD screen of the display panel. NOTE: There are identifiers to determine which device generated the code: Xy = XXXX (Co 23538) Co = Controller Ti = Control Module The controller senses the following types of malfunction: • Input voltages that are too high or too low • Input voltages in the wrong sequence or • Corr ect input voltages that occur at the wrong time

Dash Displ ay GENERAL The dash displ ay is a multifu nction devic e. It contains a truck status LED and an LCD which displays the performance mode indicator and the battery charge indicator. The menu system can be accessed through the dash display by starting the truck in service mode and entering the proper password. See Figure 4 .

• When the lift truck is operating normally, the LED will be solid green when the key is in the ON position. • If there is a fault noted by the lift truck controller and the controller has prevented traction and hydraulic functions, the LED will be solid red. • When the battery charge reaches 75% of full charge, the horn will sound and the LED will alternately blink from red to green. • If the controller has noted a condition that require the lift truck to operate at a reduced performance level, the LED will blink red.

PERFORMANCE MODE INDICATOR The performance mode indicator will show the current performance mode setting at truck startup. The indicator is a four bar display with the rabbit or highest performance level on the right and the "Turtle" or lowest perfo rmance level on the left . See Figure 5 . The performance model level can be changed using the lift and lower buttons on the steer handle as described in the Operating Manual unless the performance mode function has been locked by a supervisor or a technician. Refer to or User Interface , Technician Functions On-Board Dash Display 2200 SRM 1354.

Figure 4. Dash Display Screens

STARTUP When the key is turned to the ON position and the handle is in the full upright position, all segments of the d isplay will be illuminated and the horn will beep twice. The LED will flash red, green, and then go bla nk moment arily. Then the displ ay will show the truck mode setting and the hourmeter readin g.

STATUS LED The status LED is located in the top center of the display. When the key switch is in the ON position, the LED is on. The LED can indi cate in either re d or green depending on the information being communicated. • When the lift truck key is in the OFF position, the LED w ill be OFF .
