Operating Instructions
Safety Contact Expansion ESM-TE3..
8. Reactivating:
Close the emergency stop circuit. If
Automatic start
is selected on the safety relay, the safety contacts
will close immediately.
If the
Monitored manual start
behavior is set, close
the start button on the safety relay to close the safe-
ty contacts of the safety relay and the ESM-TE3...
What to do in case of a fault?
Device does not switch on:
f
Check the wiring of the ESM-TE3.. and the safety
relay by comparing it with the wiring diagrams (also
see operating instructions for the safety relay).
f
Check the safety switch used on the safety relay
for correct function and adjustment.
f
Check whether the emergency stop circuit of the
safety relay is closed.
f
Check whether the start button on the safety relay
(with manual start) is closed.
f
Check the operating voltage at
A1
and
A2
on the
safety relay and on the ESM-TE3...
f
Is the feedback loop closed?
Device cannot be switched on again after an
emergency stop:
f
Check whether the emergency stop circuit was
closed again.
f
Was the start button opened before closing of the
emergency stop circuit (with manual start)?
f
Is the feedback loop closed?
f
Is the power supply present during the time
sequence?
If the fault persists, perform the steps listed under
Setup 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.
Maintenance
The device must be checked once per month for
proper function and for signs of tampering and by-
passing of the safety function. 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 properly.
Disposal
Pay attention to the applicable national regulations
and laws during disposal.
