Maintenance
What to Do in
Case of a Fault?
Once per month, the device must be checked for proper
function and for signs of tampering and bypassing of the
safety function (to do this, check the wiring of the device
and activate the emergency stop function. Check the delay
time).
The device is otherwise maintenance
free, provided that it was installed proper-
ly.
Note:
Additional data can be requested from the manufacturer for
applications that deviate from these conditions.

What to Do in
Case of a Fault?
If the fault still exists, perform the steps listed under
“Commissioning Procedure”.
If these steps do not remedy the fault either, return the
device to the manufacturer for examination.
Opening the device is impermissible and will void the
warranty.
Device does not switch on:
•
Check whether the 2-hand button of correct function.
•
Check whether the wiring.
•
Check the supply voltage on A1 and A2
•
Is the feedback loop closed?
