Safety light curtain
4.2 Activation of the contactor control (EDM) without software
The contactor control can be activated without PC software as of
firmware version 123 in diagnostic mode by means of cable bridges
(refer to wiring diagram)
To activate the EDM function without PC software, proceed in the fol-
lowing way:
Establish the connections in accordance with the wiring diagram,
see below, with two cable bridges
Both outputs OSSD1 and OSSD2 of the light curtain must be
separated from the machine control
1) Wire OSSD 1 + 2 to 24 V (pin 2 + 3 + 4)
2) Wire DIAG_IN to DIAG_OUT (pin 5 + 6)
3) Wire S1 or enabling button WA between pin1 and pin2

Execute the parameter assignment according to the following
instructions:
1 Power ON
2 The light curtain detects faults and the EDM programming mode is
activated
3 Red LED flashes for 10 seconds at 2 Hz and blue LED shows during
this period of time the current EDM state (supply state: OFF = EDM
not active)
4 The EDM programming is realised, when at the same time three
impulses are emitted by button S1 at 24V Impulse duration ON time
> 200 ms, OFF time > 200 ms
5 A successful EDM programming is confirmed by the green LED flash-
ing three times (1Hz) During this time, the blue LED shows the new
EDM state (ON = EDM active) After that, the OSSD fault mode of the
light curtain is activated The red LED flashes four times If the EDM
programming was not successfull or timed out, the OSSD fault mode
of the light curtain is immediately activated The red LED flashes four
times
6 Power OFF
7 Remove cable bridges PIN 2 + 3 + 4 and if necessary cable bridge
PIN 5 + 6
8 Wire OSSD 1 + 2 (pin 3 + 4)
9 Power ON
To reverse the EDM function, repeat the procedure step 27
If the programming was not successful, the procedure can also be
repeated
The state of the EDM function is shown in diagnostic mode through the
blue LED (ON = EDM active)
An EDM function, which is deactivated by means of the PC
software, can not be activated in this way

The cables (transmitter and receiver) are permanently fixed
to the sensors by means of an M16 x 15 cable gland
The colour codes are only valid for the cable types mentioned
below "optional accessories"
5. Set-up and maintenance
Please check the need / utilisation of the function (refer to
chapter "Functions") in your application prior to the instal-
lation The functions, which require the NSR-0801 BUS
converter for the parameter settings, must be activated,
before you possibly remove the cable connector To realise
the connection in the control cabinet, we recommend not
to remove the cable connector at the sensor with additional
cable socket (plug)
