Safety Relais

10. Commissioning and function testing
After a corresponding connection of all electrical connections and switching on the supply voltage, the
system / machine must be checked for correct functionality.
After successful commissioning, the safety
STOP1
and
STOP2
outputs are driven (relay contacts “closed”).
An operation of the signal transmitter causes an opening of the relay contacts.
The signaling relay (
AUX
connection) switches in accordance with the present DIP switch position. This is
indicated by means of the yellow
AUX
LED.
The safety system must be inspected by competent specialists at suitable intervals. The check must be
documented in a way that allows it to be traced at any time. The requirements of the system / machine
manufacturer are to be taken into account and observed.
11. Fault diagnosis
If the supply voltage is correctly wired and applied, only the green Power LED may be lit up. If the red LED
illuminates, there is a fault in the system which can be delimited by means of the LED.
* If the fault is not found in the wiring, the function of the electronic system can be checked by applying
a resistance of 8.2 kΩ to the sensor-input on the switching device. Subsequently, if the electronics work
perfectly, the sensor must be checked by means of an ohmmeter. For this purpose, the connection of
the sensor to the switching device must be separated and connected by means of an ohmmeter. In the
case of a non-operated sensor the resistance must be 8.2 kΩ ± 500 Ω. If the sensor is operated, the
resistance must not exceed 500 Ω.
12. Decommissioning and disposal
The products manufactured by ASO are exclusively intended for commercial use (B2B). At the end of use, the
products must be disposed of according to all local, regional and national regulations. ASO is also happy to
take back the products and disposes of them properly.
