Cause:
The traction rotor is stuck or the encoder signal is not correctly received by the
controller.
Troubleshooting:
Please check if the sign of FREQUENCY and ENCODER on the tester menu
are the same and different than zero during a traction request.
28) “EVP DRIVER OPEN”
Cause:
The EVP driver is damaged or the EVP coil impedance is too law.
Troubleshooting:
Please check the EVP coil impedance.
If the EVP impedance is OK, the problem is inside the controller.
29) “MANY PUMP REQS”
Cause:
More than one pump functions were requested at the same time.
Troubleshooting:
Just one pump function at a time can be requested. Please reset all the
requests and try again.
30) “PUMP INC START”
Cause:
This is a warning for a pump incorrect starting sequence.
Troubleshooting:
The possible reasons for this alarm are:
A) Pump request active at keyon.
B) Pump request active without man presence.
Check the wirings. Check the micro-switches. It could also be an error
sequence made by the operator. A failurw logic is possible too. When all of the
above conditions were checked and nothing was found, replace the controller.
31) “PUMP VACC RANGE”
Cause:
The voltage on CNC#9 is outside of the parameters range.
Troubleshooting:
If the EVP TYPE parameter is set to ANALOG, please acquire again the values
of MIN LOWER and MAX LOWER.
If the controller is in Combiacx configuration and the PROPORTION. LIFT
parameter is set to ON, please acquire again also the values of MIN LIFT and
MAX LIFT.
32) “PARAM RESTORE”
Cause:
This warning appears when the controller restored the default values.
Troubleshooting:
If a CLEAR EEPROM was mode before the last keyon-recycle, this warning just
means that the EEPROM was correctly cleared. A travel demand or a pump
request cancel the alarm.
If this alarm appears at keyon without any CLEAR EEPROM request by the
operator, there could be a problem inside the controller.
33) “WAIT MOT.P. STILL”
Cause:
If TRUCK TYPE option is set to LEVEL = 1, the software expects the voltage on
