8. Commissioning

8.1 Prerequisites

• When supplying via terminals B1 and B2, the voltage must comply with the requirements for safety low
voltage (SELV).
• Cables installed outdoors or outside of the switching cabinet must be protected appropriately.

8.2 Electrical connection

• Connect 24 V DC or AC supply voltage to terminals B1 B2 or 230 V AC (115 V AC for version SK 34-82) AC
voltage to terminals A1 A2
• Connect sensor to terminals X1 X2 and Y1 Y2 ; connect 8.2 kΩ resistor to any unused inputs.
• Connect the control circuit that is to be monitored to terminals 13 14
• Connect the test signal supplied by the primary control to terminals T1 T2 and select the waveform via
DIP slide switch S1.
• For error lock with manual reset: connect release button for manual reset to terminals Z1 Z2 and select
the function via DIP slide switch S2.
The supply voltage at terminals B1 B2 is not galvanically isolated from the sensor inputs.
Following successful commissioning, relay outputs 13 14 are closed. Actuation of a sensor causes the relay
contact to open.

8.3 Connection of multiple sensors per sensor circuit

ASO sensors must not be connected in parallel.
One or more sensors can be connected to sensor inputs X1 X2 or Y1 Y2. For this purpose, the individual
sensors are connected in series according to figure 1.
Safety edges SKL:
Up to five SKL may be connected in series. The maximum total length oft the SKL shall not exceed 100 m.
The length of one SKL may be up to 25 m.
The total cable length oft the in series connected SKL must not exceed 25 m.
Safety bumper ASB:
Up to five ASB may be connected in series. The maximum total length oft the ASB shall not exceed 15 m.
The length of one ASB may be up to 3 m.
The total cable length oft the in series connected ASB must not exceed 25 m.
Safety contact mat ASK:
Up to ten ASK may be connected in series. The maximum total area shall not exceed 10 m
The maximum size of an ASK is 1350 x 2350 mm.
The total cable length oft the in series connected ASK must not exceed 25 m.
Before connecting the sensors that are connected in series, it is recommended that the resistance value of the
arrangement is to be measured. The resistance must be 8.2 kΩ ± 500 Ω when the sensor is inactive and must
not exceed 500 Ω when it is active.
