Note:
Additional data can be requested from the manufacturer for
applications that deviate from these conditions. 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?
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 by comparing it to the wiring diagrams.
• Check the safety switch used for correct function and
adjustment.
• Check whether the emergency stop circuit is closed.
• Check whether the start button (with manual start) is
closed.
• Check the operating voltage at A1 and A2.
• 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.
