Adjustment
On the SG1 no initial set up or adjustments are required, due the automatic signal-tracking
(AST) feature, that adjusts automatically each individual beam on the system.
1 Mount the transmitter (SGT) and receiver (SGR) facing each other and correctly aligned.
Wire the sensor according to the wiring diagram.
2
Make sure the load does not exceed 200 mA.
3 Check for correct wiring before turning power on. Select time-out function if required.
When the power on indicator (green LEDs) are on, the system is operating.
4 1.- If the Status indicator (red LED) is constant on the SGR cannot see the SGT.
2.- If the Status indicator (red LED) is flashing slowly one or more beams are blocked
(only if time-out is enabled).
In dynamic installations:
- For initial setup, ensure that the doors where the light curtains are installed, are in the
Note: fully open position.
- In order to prevent vandalism Telco recommends that the detectors are placed at least
5 mm in the door.
Time-out function
On "A1" model (46 mm channel spacing), up to 4 non-adjacent channels can be ignored with
time-out function enabled, when obstructed for more than 10 seconds.
On "B1" model (92 mm channel spacing), up to 2 non-adjacent channels can be ignored with
time-out function enabled, when obstructed for more than 10 seconds.
This function can be enabled (White wire disconnected) or disabled (White wire connected).
Test Input
The transmitter can be externally disabled and enabled, via the control wire, for test purposes.
Make sure no object is present in the detection area when transmitter is disabled for test.
When the transmitter is disabled, the receiver will change output.

Troubleshooting
Probable Reason
1. Symptom: Output changes when doors are closing.
Misaligned detectors.
The doors are vibrating when closing.
2. Symptom: Status indicator (Red LED) is constant on.
TX is not emitting.
SGT is disabled.
The upper channel is blocked.
2a. For "A1" models (46 mm channel spacing).
More than 4 channels blocked.
2b. For "B1" models (92 mm channel spacing).
More than 2 channels are blocked.
3. Symptom: Status indicator (Red LED) is flashing but correct function of light curtain.
3a. On "A1" model (46 mm channel
spacing), up to four non-adjacent channels
have been blocked or damaged
(time-out function activated).
3b. On "B1" model (92 mm channel
spacing), up to two non-adjacent channels
have been blocked or damaged
(time-out function activated).
On
4. Symptom: Status indicator (Red LED) is flashing and output is not working.
Two adjacent channels are blocked.
Lower channel blocked
Off
5. Symptom: Output indicator (Yellow LED) is flashing
Severe electrical interference.
Off
Severe ambient light.
Cross talk from another light curtain.
