LED Error Error correction
No LED
illuminates
The supply voltage is missing, too low
or has been connected incorrectly.
Check connections and supply voltage:
- 24 V DC at terminals +24 V 0 V
- Correct polarity? +24 V at terminal +24 V
Tolerance range: �10�
Green LED
flashes cyclically
(pulse output)
Internal error is indicated by the
number of pulses.

11. Error diagnosis
Only the green LED may illuminate if the supply voltage has been correctly connected. If one of the red LEDs
illuminate, there is an error in the system which can be pinpointed with the aid of the LED.
The yellow LEDs for the auxiliary outputs illuminate according to the DIP-switch settings.
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 sensor input on the switching unit. If the electronics work perfectly after performing the
test, the sensor must be checked using an ohmmeter. To do this, the connection of the sensor to the
switching unit 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.
