Operating Instructions
Safety Contact Expansion ESM-TE3..
5. Setting time delay:
Set the desired time delay on the rotary knob and
seal the knob with the supplied sticker. (For fixed
time variant ESM-TE3..-05S this step is not required
because a fixed time delay of 0.5 seconds is set).
Attention: Tick marks should be regarded only as
a setting aid. Always make sure to measure the
time delay.
6. Starting the device:
Switch the operating voltage on.
Attention: If the Automatic start behavior is set
on the safety relay, the safety contacts will close
immediately.
If the Monitored manual start behavior is set, close
the start button to close the safety contacts.
The LEDs K1 and K2 on the safety relay and on the
ESM-TE3.. illuminate.
7. Activating safety function:
Open the emergency stop circuit by actuating the
connected safety switch. The safety contacts of the
safety relay open immediately; the safety contacts
of the ESM-TE3.. open after the time set on the
rotary knob elapses.
Attention: Measure the time delay.
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:
Check the wiring of the ESM-TE3.. and the safety
f
relay by comparing it with the wiring diagrams (also
see operating instructions for the safety relay).
Check the safety switch used on the safety relay
f
for correct function and adjustment.
Check whether the emergency stop circuit of the
f
safety relay is closed.
Check whether the start button on the safety relay
f
(with manual start) is closed.
Check the operating voltage at A1 and A2 on the
f
safety relay and on the ESM-TE3...
Is the feedback loop closed?
f
Device cannot be switched on again after an
emergency stop:
Check whether the emergency stop circuit was
f
closed again.
Was the start button opened before closing of the
f
emergency stop circuit (with manual start)?
Is the feedback loop closed?
f
Is the power supply present during the time
f
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 time delay.
The device is otherwise maintenance-free, provided
that it was installed properly.
Disposal
Pay attention to the applicable national regulations
and laws during disposal.
