Cycle interrupted after 5 attempts during the cycle, immediately if recognised
at the start of the cycle or during diagnostics.
To check the wiring, measure
(Ω) between the following wiring
connectors of the main circuit
board (Fig.4) and compare the
values with
the correct ones
(see page 40: point 4 - motor
parameters)
- between J11-2 and J11-5, a
value as in point 4 - B (Stator)
must be found
- between J11-1 and J11-5,
where featured, a value
as in point 4 – D must be found
(half field stator).
- between J11-3 and J11-4, a
value as in point 4- C (rotor)
must be found.
Are the values correct?
Replace the circuit board and
repeat the diagnostic cycle to
check for any further alarms.
Check the motor as
on page 40.
Is the motor ok?
The motor never runs
Replace the motor and
repeat the diagnostic
cycle to check for any
further alarms.
Check/replace the
wiring and repeat the
diagnostic cycle to
check for any further
alarms.
