Stopped
Stopped
Mains voltage too low
Check the phases 3L2 and 5L3
Phase(s) missing,
Mains frequency out of range,
Too much interference
Check the phases
Check the phases
Running
Stopped
Phase(s) missing
Load missing,
Short-circuited thyristor
Check the motor connections and the
solid state switches
Bypass missing (its checking is
required by the corresponding option)
Check the bypass connections or if not
used, cancel the checking option
Stopped
Check if the connection between 5 and
6 of the control terminal block is
correctly done. Check as well if the
load current is sufficient.
Disconnect the softstarter from the
mains for a while
Stopped
Stopped
Stopped
The solid state switches can not close
Microcontroller malfunction
A problem occurred on the mains (no
voltage or a phase missing, …)
then disappeared
but the control voltage was applied
A problem occurred on the load
(temporary disconnection,…)
then disappeared
Remove the control for a while
Remove the control for a while
Stopped
but the control voltage was applied
