Error Diagnosis; Taking Out Of Service And Disposal - ASO Safety Solutions SK 31 Manuel D'utilisation

7. 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.

LEDs are not illumi-
nated
LED Actuate is illumi-
nated
LED Fault is illumi-
nated
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 ±100 Ω when the sensor is inactive and must not exceed 500 Ω
when the sensor is active.

8. 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.

Check connections, wiring and
supply lines of the sensor (squeezed
or brittle supply lines, etc.). Check

Check setting of DIP slide switch.
Adjust or check the test signal of the
primary PLC/controller and set the
DIP slide switch appropriately.
