Safety Relay

8. Error diagnosis

Only the green Power LED may illuminate if the supply voltage has been correctly connected . If one of the
other LEDs illuminates, there is an error in the system which can be pinpointed with the aid of the LED.
LED
LEDs are not illuminated
LED Actuate is illuminated
LED Fault is illuminated
*
If the error is not in the wiring, the function of the electronics can be tested by connecting an 8.2 kΩ
resistor to the respective input X1 X2 on the switching unit. If the electronics work perfectly after
performing the test, the sensors must be checked using an ohmmeter. To do this, the connection of the
sensor to the safety relay must be disconnected and connected to an ohmmeter . The resistance must
be 8.2 kΩ ±500 Ω when the sensor is inactive and must not exceed 500 Ω when the sensor is active.

Error correction
Check connections and supply voltage:
12-24 V AC/DC: 12-24 V AC/DC
Tolerance range: +10%
L1,N,PE: 230 V AC 50-60 Hz
Check connections, wiring and supply
lines of the sensor (squeezed or brittle
supply lines, etc.). Check sensor*
Check setting of DIP slide switch. Adjust
or check the test signal of the primary
PLC/controller and set the DIP slide
switch appropriately.
Check connections, wiring and supply
lines of the sensor (squeezed or brittle
supply lines, etc.). Check sensor*
