Troubleshooting
- Check if there is a short circuit or a low-impedance conduction path between
the negative of the coil and -B.
- Collect information about:
o the voltage applied across the EVP2 coil,
o the current in the coil,
o features of the coil.
Ask for assistance to Zapi in order to verify that the software diagnoses are in
accordance with the type of coil employed.
- If the problem is not solved, it could be necessary to replace the controller
184
EVP2
DRIVER
OPEN
Cause:
The EVP2 driver is not able to drive the EVP2 coil. The device itself or its driving
circuit is damaged
Troubleshooting:
This fault is not related to external components. Replace the logic board.
185
TILLER
ERROR
Cause:
Input mismatch between Hard&Soft input and tiller input : the two inputs are
activated at the same time.
Troubleshooting:
- Check if there is wrong connection in the external wiring.
- Using the
“
Tester
”
menu of the controller verify that what the controller sees
in input is in accordance with the actual state of the external switch inputs.
- Check if there is short circuit between A6 and A1
- In case no failures/problems have been found, the problem is in the controller,
which has to be replaced.
186
WAIT
MOT.P
STILL
Cause:
If DC Pump option is set to ON, the software expects the voltage on -P output to be
at a
“
steady state
”
value, before switching the LC on.
If the voltage is different, it could be due to the fact that the motor connected to -P
is not still. For this reason, the software waits 30 seconds for the voltage to be at
the
“
steady state
”
value (and for the pump motor to be still).
After this time, the software assumes that the problem is not due to the fact that the
pump motor is not still, and show the PUMP VMN NOT OK alarm.
Troubleshooting:
- If the motor connected to -P is still moving, just wait for it to be still.
- If not, in 30 seconds the alarm PUMP VMN NOT OK will appear.
187
LIFT+LO
WER
Cause:
Both the pump requests (LIFT and LOWER) are active at the same time.
Troubleshooting:
- Check that LIFT and LOWER requests are not active at the same time.
- Check the LIFT and LOWER input states through the TESTER function.
- Check the wirings.
- Check if there are failures in the microswitches.
- If the problem is not solved, replace the logic board.
