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.
