AFFZP0BB – ACE3 – User Manual
Troubleshooting
Set the two parameters with the same value, according to the adopted encoder.
29)
CONTACTOR CLOSED
Cause
Before driving the LC coil, the controller checks if the contactor is stuck. The
controller drives the power bridge for several dozens of milliseconds, trying to
discharge the capacitors bank. If the capacitor voltage does not decrease by
more than 20% of the key voltage, the alarm is raised.
Troubleshooting
It is suggested to verify the power contacts of LC; if they are stuck, is necessary
to replace the LC.
30)
CONTACTOR OPEN
Cause
The LC coil is driven by the controller, but it seems that the power contacts do
not close. In order to detect this condition the controller injects a DC current into
the motor and checks the voltage on power capacitor. If the power capacitors
get discharged it means that the main contactor is open.
Troubleshooting
-
LC contacts are not working. Replace the LC.
-
If LC contacts are working correctly, contact a Zapi technician.
31)
CONTACTOR DRIVER
Cause
The LC coil driver is not able to drive the load. The device itself or its driver
circuit is damaged.
Troubleshooting
This type of fault is not related to external components; replace the logic board.
32)
LC COIL OPEN
Cause
This fault appears when no load is connected between the NLC output (A16)
and the positive voltage (for eKEY).
Troubleshooting
-
Check the wiring, in order to verify if LC coil is connected to the right
connector pin and if it is not interrupted.
-
If the alarm is still present, than the problem is inside the logic board;
replace it.
33)
MC-EF COIL SHOR.
Cause
This alarm occurs when there is an overload of the MC driver (A16) and EB
driver (A17). As soon as the overload condition disappears, the alarm will be
removed automatically by releasing and then enabling a travel demand.
