ELMON board 32-302
Safety Relais

8.2 Supply voltage

The 230 V supply voltage must be connected to terminals L1 and N. Connect 24 V supply voltage to terminals
24 V AC/DC .

8.3 Connecting the sensor

Connect the sensor for channel 1 to terminal pair STATIONARY Opening. Connect the
sensor for channel 2 to terminal pair STATIONARY Closing.
If a channel is not used, it must be connected to an 8.2 kΩ resistor.
8.4 Connecting multiple sensors per sensor circuit
ASO sensors must not be connected in parallel.
One or more sensors can be connected to sensor input . For this purpose, the individual sensors are connec-
ted in series according to figure 1.
Safety edges SENTIR edge:
Up to five SENTIR edge may be connected in series. The maximum total length oft the SENTIR edge shall
not exceed 100 m.
The length of one SENTIR edge may be up to 25 m .
The total cable length oft the in series connected SENTIR edge must not exceed 25 m.
Safety bumper SENTIR bumper:
Up to five SENTIR bumper may be connected in series. The maximum total length oft the SENTIR bumper
shall not exceed 15 m.
The length of one SENTIR bumper may be up to 3 m .
The total cable length oft the in series connected SENTIR bumper must not exceed 25 m.
Safety contact mat SENTIR mat:
Up to ten SENTIR mat may be connected in series. The maximum total area shall not exceed 10 m
The maximum size of an SENTIR mat is 1350 x 2350 mm. The total cable length oft the in series connected
SENTIR mat 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.

Figure 1: Connection of multiple sensors; in this example: safety contact edge
For the voltage supply, either mains voltage (230 V AC 50/60 Hz) or low
voltage (24 V AC/DC) may be used.
When supplying with 24 V AC/DC, the voltage must comply with the require-
ments for Safety Low Voltage (SELV). The supply line to the switching unit
must be protected with an appropriate fuse.
Never apply both voltages simultaneously!
