Malfunction overcurrent
The locating current for the insulation fault location is
higher than the set limit value. The insulation fault loca-

ment is continued even if an insulation fault is still
active. The insulation fault location is only restarted
when the alarm message has been reset and there still
exists an insulation fault.
• Reset fault message by pressing the RESET button
• If the fault does not disappear after pressing the RESET button, the
device is defective. In this case, contact Bender Service.

more frequently
