Safety Relay ESM-BL2..
Setup procedure
Notice
The items listed under Electrical connection must
be observed during setup.
1. Wiring emergency stop circuit:
Wire the emergency stop circuit according to the
required Performance Level determined (see Fig.
5 to Fig. 7).
2. Wiring start circuit:
Wire the start circuit according to Fig. 8 or Fig. 9 to
set the starting behavior.
Attention: If Automatic start is set, bear in mind that
the safety contacts will switch immediately after the
power supply is connected. If Monitored manual start
is set, the start button must be opened after wiring.
3. Wiring feedback loop:
If your application provides for external contactors
or expansion modules, connect them to the device
according to Fig. 10 or Fig. 11.
4. Wiring power supply:
Connect the power supply to terminals A1 and A2
(see Fig. 12).
Attention: Wiring only in de-energized state.
5. Starting the device:
Switch the operating voltage on.
Attention: If the Automatic start behavior is set, the
safety contacts will close immediately.
If the Monitored manual start behavior is set, close
the start button to close the safety contacts.
LEDs K1 and K2 illuminate.
6. Activating safety function:
Open the emergency stop circuit by actuating the
connected safety switch. The safety contacts open
immediately.
7. Reactivating:
Close the emergency stop circuit. If Automatic
start is selected, the safety contacts will close
immediately.
If the Monitored manual start behavior is set, close
the start button to close the safety contacts.
What to do in case of a fault?
Device does not switch on:
Check the wiring by comparing it to the wiring
f
diagrams.
Check the safety switch used for correct function
f
and adjustment.
Check whether the emergency stop circuit is
f
closed.
Check whether the start button (with manual start)
f
is closed.
Check the operating voltage at A1 and A2.
f
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.
Is the feedback loop closed?
f
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
bypassing of the safety function. The device is
otherwise maintenance-free, provided that it was
installed properly.
Disposal
Pay attention to the applicable national regulations
and laws during disposal.
