EEPROM KO (Warning) Stored

217 ENC CAN KO (Alarm) Stored

Used only in SST/SSI models!

Cause: Can Encoder card (Model 10) does not respond via CAN-bus.

a) Check that connectors and cables are in order.

b) Change new Can Encoder card.

218 EPS REDUCTION (Warning)

Cause: Warning in the steering controller (EPS) what causes reduction of the steering functionality.

Connect handset to steering controller and check steering controller functionality.

219 ANGLE NOT VALID (Warning)

Cause: Steering system has not yet found the inductive sensors which calibrates the steering angle. Truck travel speed is reduced as long as this warning is active.

Connect handset to steering controller and check steering controller functionality.

220 MOT TH SENSOR KO (Alarm) Stored

Cause: Motor thermal sensor knockout. Motor thermal sensor either short or open circuited.

Check connector contacts and that cables are in order. Measure resistance of thermal sensor (580 ohm at 20°C)

221 LOAD SENS NOT OK (Warning) Stored

Cause: Load sensing pressure sensor out of range. Truck travel speed is limited to max load speed. a) Check that pressure sensor is calibrated correctly.

b) Check connector XB42 and that cables are in order.

c) Malfunction in the pressure sensor (Contamination can cause this problem) Change new pressure sensor.

222 EPS RELE OPEN (Warning)

Cause: Fault in EPS, which causes that the safety output is open.

Connect handset to the steering controller (EPS) and check the real fault.

223 SAFETY FEEDBACK (Alarm) Stored

Cause: This is a safety related test. The microprocessor has detected a problem on the feedback of electro valve driver.

This type of fault is not related to external components; so, when it is present it is necessary to replace the Combiac1 controller.

224 WAITING FOR NODE (Warning)

Cause: The controller receives from the CAN the message that another controller in the network is in fault condition; as a consequence the traction controller itself cannot enter an operative status, but has to wait for the other controller coming out from the fault status. The problem is inside the logic of the other controller; replace the Combiac1 controller.

225 CAN ENC KO DISP (Warning)

Cause: Display does not respond to the controller via CAN-bus.

a) Check that connectors and cables are in order.

b) Replace display

226 ACC OUT OF RANGE (Alarm) Stored

Used only in Stand on / Sit on Stackers! (Analog sensor)

Cause: Throttle minilever voltage out of range.

a) Teach minilever values again.

b) Check that connectors and cables are in order.

c) Change new minilever and teach new values.

228 TILLER OPEN (Warning) Not showed on Display

Cause: This is a warning, when the safety mat is not activated, after a fixed time in standby the main contactor open (30s).

After next travel request the warning disappear.

229 POS AUX SHORT (Alarm) Stored

Cause: The output of the built in smart driver, which supplies the positive to the electromechanical brake coil is high when the Tiller and H&S switch are open.

a) Check the wiring in order to verify that no extra positive supply is connected to the electromechanical brake when the Tiller H&S switch are open, at connector XA1 pin 30.

b) The driver circuit is damaged inside the Combiac1 controller, which has to be replaced.

231 COIL SHORT HW KO (Alarm) Stored

Cause: The hardware circuit which manages short circuit protections for the main contactor and the electromagnetic brake coils has a problem.

This type of fault is not related to external components; so, when it is present it is necessary to replace the Combiac1 controller.

232 WRONG SET POINT (Alarm) Stored

Cause: This is a safety related test. The microprocessor has detected a wrong traction function set point.

This is a internal fault of the Combiac1 controller, so it must be replaced.

233 POWER MOS SHORT (Alarm) Stored

Cause: Before switching the main contactor on, the software checks the power bridge: it turns on alternatingly the low and high side power mosfets and expects the phase’s voltage to decrease down to –BATT. If the phase’s voltage does not follow the commands, this alarm occurs.

This type of fault is not related to external components; so, when it is present it is necessary to replace the Combiac1 controller.

236 CURRENT GAIN (Alarm) Stored

Cause: The maximum current gain parameters are at default values, which mean the maximum current procedure has not been carried out.

This type of fault is not related to external components; so, when it is present it is necessary to replace the Combiac1 controller.

237 ANALOG INPUT (Alarm) Stored

Cause: This alarm occurs when the conversion of the analog inputs gives frozen values.

If the alarm occurs permanently, it is necessary to replace the Combiac1 controller.

239 PUMP WARNING (Warning)

Cause: This is a warning from the pump controller.

Connect the console to the pump controller and check the warning.
