Faults, Causes Of Faults And Rectification Of Faults - Siemens SENTRON 3VA1 Manual

4.6.3.3

Faults, causes of faults and rectification of faults

"Device defective" refers to a fault or defect in the motor operator which cannot be rectified.
The device must be replaced. This can be caused by a defective microswitch, for example.
"Internal error" refers to faults which can be rectified (e.g. an undefined switching position,
fault on automatic RESET, excessively long switching times). If the motor operator fault
condition cannot be rectified by (remotely) switching it ON/OFF again, the following actions
are necessary:
● Ensure that the rotary switch for RESET mode is in a defined state (1, 2 or 3)
● Correct the switching position manually (manually charge the stored energy and operate
the ON/OFF button).
