Installation & Adjustments
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, or close to the door plane of vertically
sliding doors. If the light curtain is placed in the door plane, it is important that the lowest part
of the door leaf will efficiently obstruct the light beams over a height of 55 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
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.
1
Use the brackets supplied with the light curtain (at least 2 pcs, with max distance of
135 cm) to mount the transmitter (SGT) and receiver (SGR) facing each other and
correctly aligned.
2
Correct alignment is achieved when the front cover of the light curtains are parallel
and when a virtual line connecting top of the transmitter and receiver are
perpendicular to both transmitter and receiver front cover. (Within 2 deg.)
3 The light curtain has to stand on the pin in the bottom, in order to ensure that the
protective field is correctly positioned and in compliance with EN 12445
4 Wire the sensor according to the wiring diagram.
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.
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 Trin order to ensure that
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 TON .
When the test input of SGT/R is deactivated the output will be switched back within a certain
maximum time TOFF.
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 “.

How the test inputs are to be operated depends on digit 0X on transmitter (SGT) and X9 on
receiver (SGR) in the model code;
SGT 15-xxx-0xx-x1-E-0X-xx
SGR 15-xxx-0xx-x1-E-X9-xx
Make sure no object is present in the detection area when test is done.

Dynamic Blanking Function
Dynamic Blanking Function
All the infrared light beams can be blanked out (made inactive) without de-energizing the
output of the receiver by moving a non-transparent object, as the door leaf, between the SGR
and SGT from top of the rails (wire end) and downwards to the lowest beam. It is important
that one beam always is obstructed during the blanking. Beams are blanked in (activated)
when the door motion is reversed.
Make sure that the lowest beam is kept well obstructed, when door has finished closing.
The light curtain supports partial opening of the door, for energy saving. The test is done, when
the door is in the top position in the detection zone. The blanked beams are ignored.
Maximum closing speed (Note 1) 0.9 m/s
There is no restriction on maximum speed when the door is opening
Note 1: For SG 15 systems with fewer than 56 channels the maximum allowable speed will be higher.
Notice that the actual speed of the bottom door edge can fluctuate for a non-rigid door construction
and it is advised that the door speed therefore has to be set lower than 0.9 m/s, in order not to
exceed the maximum speed limit of the light curtain while the door is closing.
Be aware that side to side movements of a round bottom door edge will also contribute to the
fluctuation of the obstruction speed. It is therefore best to have a horizontal straight edge for
obstruction of the light beams.
Troubleshooting
Troubleshooting
Probable Reason Corrective Action
1. Symptom: Red LED on SGT/R is constant on. All other LEDs are off.
Error found during test process Check supply and cable to the SGT/R.
Or replace the rail(s).
2. Symptom: Red and green LEDs on SGT is constant on.
Error found during test process Replace the SGT rail.
3. Symptom: Red and green LEDs on SGR is constant on.
Error found during test process Replace the SGR rail.
4. Symptom: Yellow LED on SGR is flashing
Cross talk from another light curtain, or
other powerful light sources. Change position of the SGT and SGR rails.
5. Symptom: Yellow LED on SGR is constant off. Red LED is off.
Rails are out of sensing range Check the sensing range and power to the SGT.
6. Symptom: After start up, red LED on SGR continues to flash quickly. Green LED is on.
Rails are out of sensing range or
SGT is not turned ON or an object is
obstructing one or more beams.
Check the sensing range and for objects
between the SGT and the SGR.
Check SGT is powered or replace rails.
7. Symptom: After start up, green LED on SGT/R is on. Yellow LED on SGR is off.
Test input is constant activated under and
after start up. Deactivate the test input on SGT/R.
Disposal
Disposal
The light curtain should only be replaced if a similar protection device is installed. Disposal
should be done using the most up-to-date recycling technology according to local rules and
laws.
