7.3 Potential-free switching contacts and universal power supply
The ULSG switchgear provides potential-free output contacts and a universal power supply (either 230 VAC, 115 VAC, or
24VDC connection). The ULSG switchgear performs the power failure bridging of 20 ms pursuant to EN 60204 and is
thus suitable as the power supply for ULVT light barriers.

Connection examples
230 VAC connection / external contactors
control hazardous movement
Having pressed the start button with a free
protective field, the potential-free output contacts
13-14 and 15-16 close and the connected
contactors K1 and K2 respond. When activating
the closing movement via contactors K1 and K2,
the respective make contacts of K1 and K2 must
be switched in series!
The connecting pin 2 (EDM = contactor check)
on the receiver also provides an additional
check of the contactors or hydraulic valves
which activate the hazardous movement.
If the protective field is penetrated, the output
contacts are opened and the movement
interrupted.
Operation can only be continued once the start
button has been pressed. The activation of a
new operating stroke or a hazardous movement
will only be performed if both or valves K1 and
K2 had fallen when the protective field, and the
protective field is subsequently free again.
In the operating mode without restart interlock,
the connecting pin 1 (start) on the receiver must
be left free.
24 VDC connection / the output contacts 13-
14 and 15-16 directly control the hazardous
movement
Control of the hazardous movement of the
operating material is performed directly via the
potential-free output contacts 13-14 and 15-16.
The activation of the hazardous movement is
implemented as described in the above
example.
In the operating mode without restart interlock,
the connecting pin 1 (start) on the receiver must
be left free.

When performing electric welding work on the machine, the terminal strip of the
switchgear is to be removed, otherwise the vagrant welding currents may cause
destruction of the installed electronics.
Cable routing: Separately from power lines.
The hazardous movement must only be activated via output contacts 16-17 and
20-21. The output contacts are potential-free, monitored, guided make contacts
are must be loaded with max. 2 A/250 VAC or 60 VDC, 30 W. With inductive load,
the load (not the contacts) is to be switched at the same time as the spark

To increase the switching reliability, collateral contacts should be used on
