Errors and technical changes reserved
Note:
The items listed under “Electrical connection” must be observed during commissioning.
Commissioning
Procedure
5. Starting the device:
Switch on the operating voltage.
Warning:
If the “Automatic start” starting behavior is set, the safety
contacts will close immediately.
If the “Monitored manual start” starting behavior is set, close
the start button to close the safety contacts.
LEDs
K1
and
K2
are lit.
6. Triggering safety function:
Open the emergency stop circuit by actuating the connected
safety switch. The safety contacts open immediately.
7. Reactivation:
Close the emergency stop circuit. If “Automatic start” is
selected, the safety contacts will close immediately.
If the “Monitored manual start” starting behavior is set, close
the start button to close the safety contacts.

Monitored manual start.
It is monitored that the start
button was opened before the
emergency stop button closes.
(Prerequisite: operating voltage
must not be interrupted.)

Automatic start.
Max perm. delay during closing
of the safety switches on S12
and S13:
S12 before S13: 300 ms
S13 before S12: any
Warning:
Safety contacts switch
immediately when the
power supply is connected.
Depending on the application or the result of the risk assessment according to EN ISO 13849-1, the device must be wired as
shown in Fig. 1 to Fig. 11.

Voltage „+V“ according to techn.
Data)
Notice:
In order to activate earth fault monitoring, S10 must be
connected to PE (protective earth) on the AC 115/230 V
devices. With AC/DC 24 V, connect PE only to the power
supply unit according to EN 60204-1
Corresponded to the application, the starting circuit have to
be wired according to Fig. 6 or Fig. 7.

(category 4, up to PL e)
1. Input circuit:
Depending on the risk evaluation choose one of the wiring
diagrams in „Applications“ (Fig. 1 to 5).
2. Choose start mode:
Connect the start button with S11 and S21 for monitored
manual start or connect S21 with S12 directly for automatic
start (Fig. 6 or 7).
Warning:
If “Automatic start” is set, bear in mind that the safety con-
tacts will switch immediately after the power supply is
connected. If “Monitored manual start” is set, the start
button must be opened after wiring.
3. Feedback loop:
If external contactors or extension modules are used,
connect them according to Fig. 8 or Fig. 9.
4. Power supply:
Connect the power supply to A1 and A2 (Fig. 10).
Caution:
Power must not yet be activated.
