Short Circuit Thyristor
One or more of the internal
control thyristors (SCRs) have
failed short circuit.
The Unit has detected that the
SCRs are not operating as
expected.
ISOLATE MOTOR
Disconnect supply. Check by
measuring the resistance
between L1-T1 L2-T2 L3-T3
(Anything < 10R is assumed
short circuit).

Low Current Trip
The motor current has been
lower than the low trip level for
the low trip time.
This trip is not active during
soft start and soft stop and is
"off" by default.
If the low current trip is not
required turn "off" in "Trip
Settings".

The motor has been held in
current limit longer than the
"Start current limit Time".
It is likely that the current limit

the application.
Increase the current limit level
or timeout period.

Overload Trip
The "Overload" has exceeded
100%.

an application that is outside
its capacity or it is starting too
often.
Refer to the overload trip
curves to determine whether
the Unit has been sized
correctly.
