5.6 Notes
Signalling outputs must not be used in safety circuits.
Opening the front cover (see Fig. 2)
• To open the front cover, insert a slotted screwdriver in the top and
bottom cover notch and gently lift it.
• When the front cover is open, the electrostatic discharge requirements
must be respected and observed.
• After setting, the front cover must be fitted back in position.
Only touch the components after electrical discharge!
Setting the switch (see Fig. 3)
• The cross-wire short monitoring function (factory setting) is pro
-
grammed by means of the switch underneath the front cover of the
safety-monitoring module.
• The switch must only be operated in de-energised condition by means
of a finger or an insulated blunt tool.
• Pos. nQS (top): Not cross-wire short proof: QS-LED off
Suitable for 1-channel applications and applications with outputs
connected to potential in the control circuits.
• Pos. QS (bottom), Cross-wire short proof: QS-LED on
Suitable for 2-channel applications without outputs connected to
potential in the control circuits

6. Set-up and maintenance
6.1 Functional testing
The safety function of the safety-monitoring module must be tested.
The following conditions must be previously checked and met:
1. Correct fixing
2. Check the integrity of the cable entry and connections
3. Check the safety-monitoring module's enclosure for damage
4. Check the electrical function of the connected sensors and their influ-
ence on the safety-monitoring module and the downstream actuators
6.2 Maintenance
A regular visual inspection and functional test, including the following
steps, is recommended:
1. Check the correct fixing of the safety-monitoring module
2. Check the cable for damages
3. Check electrical function
The device has to be integrated into the periodic check-ups
according to the Ordinance on Industrial Safety and Health,
however at least 1 × year.
Damaged or defective components must be replaced.
