Group 19, Motor Controls
SM 765, Sep ’06 Description • 19-1-3
Standard Fault Codes
The control has over 75 fault codes assist the service tech-
nicians and operators in the trouble shooting the vehicle.
If mis-operation of the vehicle occurs, a fault code will be
displayed on the Dash Display of the vehicle, or by plug-
ging the handset into the "B: plug of the master controller
and reading the fault code.
With the fault code number, follow the procedures out-
lined in Group 19, Section 03 ,"Fault Codes", section to
determine the problem and a solution.
Stored Fault Codes
This feature records the last 5 fault codes in controller.
The last 5 fault codes can be accessed through the alarm
log using a handset, or a laptop computer with the PcCon-
sole software and adapter cable. The faults are stored with
the hour meter reading when the fault first happened, the
number of time the fault has happened, and the tempera-
ture the first time the fault happened.
Hour Meter Readings
When the traveling speed is less than 0.5km/h, it displays
the accumulated operating hour.
Battery Discharge Indication (BDI)
Provides accurate battery state of charge information to
the vehicle operator, Features and Functions:
• Displays 100 to 0 percent charge in 10% incre-
ments.
• Lift Circuit is disabled at 10% discharge
Handset
This is a multifunctional tool used with the AC controls.
The handset (Clark part #8033636) has a display and a
key board for data entry.
Features and functions:
• Monitor existing fault codes for both traction and
pump controls.
• Monitor hour meter readings on traction and pump
controls.

Protection Features
Reverse Battery Polarity:
The MAIN CONTACTOR is there to protect the control-
ler against reverse battery polarity and for safety reasons.
Connection Errors:
All inputs are protected against connection errors.
Thermal Protection:
If the controller temperature exceeds 80° C, the maximum
current is reduced in proportion to the thermal increase.
The temperature can never exceed 100° C.
External Agents:
The controller is protected against dust and the spray of
liquid to the degree of protection meeting IP54.
Protection Against Uncontrolled Movement:
The main contactor will not close if:
− The power unit is not functioning
− The controller is not functioning perfectly.
− The output of the accelerator does not fall
below the minimum voltage value stored, with
1V added
− Running microswitch is in closed position.
Low Battery Charge:
When the battery charge is low, -66 Code, the maximum
current is reduced to half the maximum current pro-
grammed.
Protection against accidental startup:
A precise sequence of operations is necessary before the
control will start (SRO). Startup cannot occur if the
