9. 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 using the table.

[1] 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 appropriate input X1 X2 or Y1 Y2 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.
The constant flashing indicates error lock of the switching unit and requires manual release by actuating the
[2]
reset button. Evaluation of the reset button occurs dynamically; as a result, constant actuation or manipula-
tion of the reset button will be detected by the switching unit and release of the output circuits prevented.
The test of the safety system must be coordinated by the primary controller and be designed according to
[3]
the technical data specified in this documentation. If the test fails in spite of appropriate settings, there
is a defect in the switching unit.

10. 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 and supply voltage:
230 V 50/60 Hz at terminals A1 A2 or 24 V AC/DC at
terminals B1 B2. Tolerance range: ±10%
Check connections, wiring and supply lines of the
respective sensor for short circuit (squeezed or
brittle supply lines, etc.).
Check sensor. [1]
Check connections, wiring and supply lines of the
sensor for breakage (squeezed or brittle supply
lines, etc.).
Check sensor. [1]
Check operating mode, reset push-button, wiring
and supply line. [2]
Check DIP slide switch S1. Adjust or check the test
signal of the primary PLC/controller and set the DIP
slide switch appropriately. [3]
