6. Commissioning

6.1 Prerequisites

• The supply voltage used must comply with the requirements for Protective safety low voltage (SELV).
• Cables installed outdoors or outside of the switching cabinet must be protected appropriately.
• The limit values for the supply voltage and the switching capacity of the relay specified in the "technical
specifications" are to be observed.
6.2 Connecting the suppl�� voltage
• Connect 24 V AC/DC supply voltage to terminal pair 8 9 .

6.3 Connecting the sensors

Connect the sensor for channel 1 to terminal pair 3 11 .
If several SCEs are being used, they must be connected in series and the end edge
must be terminated using an 8.2 k� resistor.
Connect the sensor for channel 2 to terminal pair 3 10 .
If a channel is not used, it must be connected to an 8.2 kΩ resistor.
6.4 Connecting the control circuit
The control circuit to be monitored for channel 1 is to be connected to terminal
pair 4 5 and the corresponding control circuit for channel 2 is to be connected to
terminal pair 6 7 .
Both outputs are redundant and self-monitoring with forcibly actuated relays and
thus comply with the safety category 3 requirements in accordance with EN ISO
13849-1:2008 and the requirements of all relevant standards governing gates.
Upon successful commissioning, the outputs of the safety relays are activated (relay contact "closed"). An
actuation of the sensor causes the corresponding relay contacts to open.
