General Instructions and Precautions
Even though the light curtain has a high degree of immunity to ambient light sources, it is
recommended to avoid direct exposure to sunlight and interference from flashlights or other
infrared light sources (such as other photoelectric sensors).
If the front cover or the opto components of the light curtain become contaminated, then they
have to be cleaned with a slightly damp cloth. Do not use organic solvents or detergents.
Ensure that the light curtain is mounted so that it is mechanically stable during operation.
Severe rain and snow may be detected due to the high sensitivity of the system.
SG 17 Master/Slave Configuration (installation of double light curtains)
It is possible to mount 2 light curtains in line with thick and heavy doors.
The two light curtains sets must then have a common 0V - GND, + supply, SGT control input
and synchronisation connection as shown below.
The polarity's connection defines the Master set and the Slave set. The set connected with the
standard polarity will act as Master set. And the set connected with the reversed polarity will
act as Slave. A SG 17 set connected as a slave (reversed polarity) will not run without
connection to a SG 17 Master set.
Note: Please check the polarity of the load when connecting it as PNP or NPN on the receiver
in slave mode (SGR slave). The SG 17 slave set is powered with the connections inverted
(+ blue and - brown).
SG 17 Master/Slave wiring
Installation and Adjustment
No initial set up or adjustments are required, due to the automatic signal-tracking (AST)
feature, which automatically adjust each individual channel on the system.
Mount the transmitter (SGT) and receiver (SGR) facing each other and correctly
aligned.
1 The bottom beam is 35 mm above ground if the rails stand on the ground on the pin.
The pin can partially or completely be cut off if the light curtain needs to be lowered
relative to support structure.
Fix the mounting clips in line and parallel.
2
The maximum distance between the points of fixture should not exceed 135 cm.
Wire transmitter and receiver according to the wiring diagram.
3
Make sure the load does not exceed 100 mA.
4 Check for correct wiring.
5 Turn power on.
When the power on indicators (green LEDs) is on, the system is operating.
6
No initial set up or adjustments are required.
