General Instructions and Precautions
This light curtain can be used in industrial, commercial and garage doors and gates, as
described in EN 12453, when it is used as device type E according to clause 5.5.1. The light
curtain is intended to be mounted in the door plane of vertically sliding doors. It is important
that the lowest part of the door leaf will efficiently obstruct the light beams over a height of 50
mm.
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 photo sensors.
If the front cover of the light curtain becomes contaminated, they have to be cleaned with a
slightly damp cloth. Do not use organic solvents or detergents. If the light curtain is very
contaminated, the output may go into safe state and de-energize even after the cleaning, due
to safety reasons. The light curtain will automatically make the necessary internal adjustments,
and within less than a few minutes, the light curtain will be fully adjusted and resume normal
operation. Immediate adjustment can be forced by switching the light curtain off and then on
again.
Ensure that the light curtain is mounted, so that it is mechanically stable during operation.
The light curtain must not be placed on moving doors.
Severe rain and snow may be detected due to the high sensitivity of the light curtain.
Indicators
SGT SGR
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.
Use the brackets supplied with the light curtain (at least 2 pcs, with max distance of
1 135 cm) to mount the transmitter (SGT) and receiver (SGR) facing each other and
correctly aligned.
Correct alignment is achieved when the front cover of the light curtains are parallel
2 and when a virtual line connecting top of the transmitter and receiver are
perpendicular to both transmitter and receiver front cover. (Within 2 deg.)
The light curtain has to stand on the pin in the bottom, in order to ensure that the
3
protective field is correctly positioned and in compliance with EN 12445
Wire the sensor according to the wiring diagram.
4
Make sure the load does not exceed 100 mA.
5 Check for correct wiring.
6 Turn power on.
7 The status indicator (red LED) on the SGR will flash quickly when the AST is active.
8 When the power on indicators (green LEDs) is on, the system is operating.
9 Notice that the rails must not be moved after the power to the SGR is turned on.
Safety Test - SGT/R Test Input
The function of the light curtain has to be tested before any door closing cycle (EN 12978
2009, 4.4.3), by activating the test input of the transmitter and the receiver. The SGR and the
SGT test input wires must be connected together. The test is enabled and disabled via the
black (SGT) and white (SGR) control wire. (See "Wiring Diagrams" and table below).
Activation of the test input will initiate an extensive internal safety test in both the transmitter
and the receiver. A faulty receiver or a faulty transmitter will turn on red led and go into safe
mode; the transmitter will stop transmitting and the receiver will de-energise the output until
test is repeated again with success.
An external controller ensures that the receiver de-energizes the output when the test inputs
are activated and that the receiver energizes the output when the test inputs are de-activated
again.
The test input on SGT/R has to be activated a certain minimum time T
the test request is registered and a test sequence is initiated.
On activation of the SGT/R test input, the output of the receiver will switch within a certain
maximum time T .
ON
When the test input of SGT/R is deactivated the output will be switched back within a certain
maximum time T .
OFF
By only activating the test input on the SGT, a switch in output of the SGR should be observed.
If only the SGR test input is activated, no change in its output should be observed.
There must be at least 500ms from the start of one test pulse to the start of the next test pulse.
Note: Refer to "SGT/R Test Input Response Time ".
