13.1.6 Six Blinks Alarms
1) STBY I HIGH
CAN Bus Code = 53
- Cause: This alarm occurs two ways:
1) In the initial rest state after key on, if the outputs of the current
amplifiers are not comprised in the window 2.2 to 2.8 Vdc.
2) After the initial diagnosis this alarm occurs when the outputs of
the current amplifiers at rest have a drift larger than ±0.15 V.
- Remedy: It is necessary to replace the controller.
2) VMN NOT OK
CAN Bus Code = 32
- Cause: This alarm occurs in the initial rest state after key on if the outputs
of the motor voltage amplifiers are not in the window from 2.2 to
2.8 Vdc.
- Remedy: It is necessary to replace the controller.
3) LOGIC FAILURE #3
CAN Bus Code = 17
- Cause: This alarm occurs in the rest state if the output of the voltage
amplifier of the phase Vu-Vw have a drift larger than ±0.25 V.
- Remedy: It is necessary to replace the controller.
4) LOGIC FAILURE #4
CAN Bus Code = 16
- Cause: This alarm occurs in the rest state if the output of the voltage
amplifier of the phase Vw-Vv have a drift larger than ±0.25 V.
- Remedy: It is necessary to replace the controller.
13.1.7 Thirty-two Blinks Alarms
1) DATA ACQUISITION
MDI-PRC Code = 245
- Cause: This alarm occurs two ways:
1) When hardware setting AUTOTEACHING is turned On and the
key recycled. Then, during the consequent autoteaching
procedure, a DATA ACQUISITION alarm occurs
2) When acquiring the motor resistance or when adjusting the
parameters to compensate for the gain of the current amplifiers
(maximum current factory adjusted).
- Remedy: Recycle the key.
13.1.8 No Blink Alarms (Warning)
These alarms do not cut the truck off; they only reduce the truck speed. So they
warns the operator of a particular state in the truck.
1) STEER HAZARD
CAN Bus Code = 85
- Cause: This is just a warning to inform that the steering controller is
limiting the angle in the steering direction. No speed reduction
occurs on the traction.
