Time -Delayed Safety Relay ESM-TE3..
Maintenance
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).

Safety
Characteristics
According to
EN ISO 13849-1
The device is certified according to EN ISO 13849-1 up to a
Performance Level of PL e.
Device cannot be switched on again after an emergency
stop:
•
Check whether the emergency stop circuit was closed
again.
•
Was the start button opened before closing of the emer-
gency stop circuit (with manual start)?
•
Is the feedback loop closed?
•
Is the power supply present during the time sequence?
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 the wiring of the ESM-TE3..and the basic device
by comparing it with the wiring diagrams (also see user
information for the basic device).
•
Check the safety switch used on the basic device for
correct function and adjustment.
•
Check whether the emergency stop circuit of the basic
device is closed.
•
Check whether the start button on the basic device (with
manual start) is closed.
•
Check the operating voltage at A1 and A2 on the basic
device and on the ESM-TE3...
•
Is the feedback loop closed?
What to Do in
Case of a Fault?
The device is otherwise maintenance free, provided that it
was installed properly.
