- 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.
14.1.7 Thirty-two Blinks Alarms
1) DATA ACQUISITION
MDI-PRC Code = 245
- Cause: This alarm occurs when the 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.
14.1.8 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.
2) WAITING DATA
CAN Bus Code = 237
- Cause: This warning occurs only if CAN BUS is PRESENT. At key-on the
eps-ac0 asks to the traction controller to send a list of parameters
via CAN Bus. From the request until the parameters are correctly
relieved, this warning occurs. The steer is not activated yet, and
the safety relays remain open when this warning is present.
3) WAITING FOR TRAC
CAN Bus Code = 239
- Cause: At key-on the eps-ac0 needs an assent from the traction controller
to close the safety contacts and to turn onto operational mode.
Until this assent is not relieved, this warning occurs. The steer is
not activated yet and the safety relays remain open when this
warning is present.
4) EPS NOT ALIGNED
CAN Bus Code = 238
- Cause: This is a real alarm that cut off the traction. It occurs at the initial
alignment if the straight-ahead condition is not matched within
6sec. Throughout this 6 secs delay, the steer is not activated yet,
the safety relays are open and the traction is stopped.
