Eliminating malfunctions
CAUTION
There is a malfunction on the compact starter.
A compact starter malfunction will cause the compact starter to shut down. Continuing to
operate the compact starter is extremely risky, as it can no longer be considered reliable.
Following a shutdown caused by a malfunction, you will need to replace the compact
starter.
In order to achieve a safe system status, you can continue operating the compact starter for
a short time. For this purpose, you will have to set the compact starter to "ready" again by
turning the actuator to the OFF position and then to the READY position.
Note
Once the malfunction has been reset, the white field will continue to be displayed in the
"RLT 0%" display window. The compact starter must be replaced.
