ISK 77 / SPK 77 Inductive Safety Relay

9.5. Commissioning / functional test

The plant / machine must be tested for proper function after all of the electrical connections have
been established and the suppl�� voltage has been turned on.
• Actuate the sensors in sequence.
• Check the switching units for proper reaction.
The safet�� s��stem must be professionall�� inspected at appropriate intervals. The inspection must
be documented in such a wa�� as to be comprehensible at all times. The requirements of the plant/
machine manufacturer are to be taken into account and followed.

10. Error diagnosis

If the suppl�� voltage is both wired and applied correctl��, the decimal point must switch off c��clicall��
on the display only briefly. If an internal error has occurred, the error message is indicated by the
number of pulses.

If the error is not in the wiring, the function of the electronics can be tested b�� connecting an
8.2 kW resistor to the respective SCE input on the switching unit.

11. Taking out of service and disposal

The products manufactured b�� ASO are intended solel�� 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 properl��.
