The colour codes are only valid for the cable types
mentioned below "optional accessories"
For UL evaluated products we do recommend to use the
UL style cable 20549.
5. Set-up and maintenance
5.1 Check before start-up
Prior to start-up, the following items must be checked by the responsi-
ble person
Wiring check prior to start-up
1 The voltage supply is a 24V direct current power supply (see techni-
cal specifications), which meets the CE Directives, Low Voltage
Directives A power downtime of 20 ms must be bridged
2 Presence of a voltage supply with correct polarity at the SLG
3 The connecting cable of the transmitter is correctly connected to the
transmitter and the connecting cable of the receiver correctly to the
receiver
4 The double insulation between the light grid output and an external
potential is guaranteed
5 The outputs OSSD1 and OSSD2 are not connected to +24 VDC
6 The connected switching elements (load) are not connected to +24
VDC
7 If two or more SLG are used within close range compared to each
other, an alternating arrangement must be observed Any mutual
interference of the systems must be prevented
Switch the SLG on and check the operation in the following way:
The component performs a system test during approx 2 seconds after
the operating voltage has been switched on (indication through 7-seg-
ment display) After that, the outputs are enabled, if the protection field
is not interrupted The LED "OSSD ON" at the receiver is on
In case of incorrect functionality, please follow the instructions
listed in the chapter Fault diagnostic
5.2 Maintenance
Do not use the SLG before the next inspection is terminated
An incorrect inspection can lead to serious and mortal
injuries
Conditions
For safety reasons, all inspection results must be archived The operat-
ing principle of the SLG and the machine must be known in order to
be able conducting an inspection If the fitter, the planning technician
and the operator are different persons, please make sure that the user
has the necessary information at his disposal to be able conduct the
maintenance
