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.
LED
No LED The supply voltage is missing,
illuminates too low or has been connected
incorrectly
green LED Internal error is indicated by the
flashes cyclically number of pulses.
(pulse output)
red LED The corresponding safety sensor
is illuminated detected as having been actuated.
(CH1 or CH2)
red LED sensor circuit interrupted , Sensor(s)
flashes fast not connected,
(CH1 or CH2) connected incorrectly or faulty.
red LED error lock
flashes slowly
(CH1 or CH2)
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.

12. Taking out of service and disposal

The products manufactured by ASO are intended solely for commercial use (B2B). At the end of use, the
products are to be disposed of according to all local, regional and national regulations. Products can also be
returned to ASO, which will then dispose of them properly.
