What to Do in the Event of a Fault
In case of a fault, use the checklist to determine whether a fault with the ZPA motor control
module can be remedied.
If none of the information specified in the checklist solves the problem, in the event of queries
contact Fuchs via your sales office. Have the type designation and firmware version of
the product ready.
In the following checklist, "x" represents the channel for the LED descriptions and can be either
"1" or "2".
Checklist
Fault
Possible cause
Remedy
No LED is lit.
The power supply is not
connected or is connected
with reverse polarity.
Check the connection of the
power supply.
ZPA motor control module is
not working, the four yellow
LEDs (X1 IN ... X2 OUT) are
flashing.
An invalid (reserved)
operating mode has been
selected.
Use rotary switch S3 to select
a valid operating mode. After
the correction, you must
disconnect the power supply
for a short period of time to
implement the change.
DC roller motor is not running,
even though the relevant LED
"MOTx" is lit and the
associated LED "ERRx" is not
lit.
An invalid speed setting has
been selected.
Set a valid speed using rotary
switch S1. After the correction,
you must disconnect the
power supply for a short
period of time to implement
the change.
DC roller motor is not running,
even though the relevant LED
"MOTx" is lit. The associated
LED "ERRx" lights up
permanently.
The DC roller motor reports a
fault, for example due to
blocking or the DC roller motor
is not connected correctly.
Check the connection of the
DC roller motor. You may have
to briefly disconnect the power
supply of the module to reset
the fault in the DC roller motor.
DC roller motor is not running,
even though the relevant LED
"MOTx" is lit. The associated
LED "ERRx" is flashing.
The internal safety fuse of the
module for the DC roller motor
is faulty, for example due to
overcurrent.
Replace the ZPA motor
control module. Check the
current consumption of the
DC roller motor causing the
problem before the next
commissioning.
The conveyed product is not
detected in a zone. The
relevant LED "INx" of the zone
is not lit.
The corresponding zone
sensor is faulty or not
connected correctly.
Check that the zone sensor is
connected correctly. Check
that the zone sensor is
functioning correctly.
The conveyed product does
not exit the zone. The zone is
not receiving a release signal
from the downstream zone.
The associated LED "X1
IN"/"X2 IN" is not lit.
The zone coupling signal lines
are not connected correctly.
The logical zone
interconnection is not correct.
Make sure that the zone
coupling to the downstream
zone is connected correctly
and the downstream zone
sets the release signal
(associated LED "X1
OUT"/"X2 OUT" of the zone
coupling is lit).
Check the setting of the
conveyor direction on the
corresponding ZPA motor
control modules.
