Electrical Connection; Connection Of Multiple Sensors Per Sensor Circuit - ELMON rail 35-82 Manuel D'utilisation

ELMON rail 35-32 / ELMON rail 35-82
Safety Relay

8.2 Electrical connection

• Connect 24 V DC or AC supply voltage to terminals B1 B2 or 230 V AC supply voltage (115 V ELMON rail
35-82) to terminals A1 A2
• During use mains voltage it´s advisable to include a delay fuse protection of 1 A.
• Connect sensor to terminals X1 X2 and Y1 Y2; connect 8.2 kΩ resistor to any unused inputs.
• Connect the control circuits to be monitored to terminals 13 14 and 23 24.
• 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 and 23 24 are closed. The actuation of a sensor
results in the opening of the respective relay contact 13 14 or 23 24.
Sufficient fuse protection must be provided on all output contacts with capacitive and
inductive loads.

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.
An unused input can be bridged with an 8.2 kΩ resistor.
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
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.
