Safet�� edges SKL:
Up to five SKL may be connected in series. The maximum total length oft the SKL shall not exceed 100 m.
The length of one SKL may be up to 25 m.
The total cable length oft the in series connected SKL must not exceed 25 m.
Safet�� bumper ASB:
Up to five ASB may be connected in series. The maximum total length oft the ASB shall not exceed 15 m.
The length of one ASB may be up to 3 m.
The total cable length oft the in series connected ASB must not exceed 25 m.
Safet�� contact mat ASK:
Up to ten ASK may be connected in series. The maximum total area shall not exceed 10 m
The maximum size of an ASK is 1350 x 2350 mm.
The total cable length oft the in series connected ASK must not exceed 25 m.
Before connecting the sensors that are connected in series, it is recommended that the resistance value of
the arrangement is to be measured. The resistance must be 8.2 k� ± 500 � when the sensor is inactive and
must not exceed 500 � when it is active.

6.7 Functional test

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

7. Error diagnosis

Onl�� the green Power LED may illuminate if the supply voltage has been correctly connected. If one of the
red LEDs illuminates, there is an error in the system which can be pinpointed with the aid of the LEDs.
If such an error is signalled, the connections of the individual sensors should be inspected. If the error is not
at the connections, the function of the electronics can be tested by connecting an 8 .2 k� resistor to all sensor
inputs on the electronics (terminals 3 10 and terminals 3 11) . If the electronics work perfectly after performing
the test, the sensors must be checked using an ohmmeter. To do this, the respective connection of the sensor
to the safety relay must be disconnected and connected to an ohmmeter. The resistance must be 8.2 k� ±500 �
when the sensor is inactive and must not exceed 500 � when it 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.
