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.
2 Wire the sensor according to the wiring diagram.
Make sure the load does not exceed 200 mA.
3 Check for correct wiring before turning power on. Select time-out function if required.
4
When the power on indicator (green LEDs) are on, the system is operating.
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).
Note:
In dynamic installations:
- For initial setup, ensure that the doors where the light curtains are installed, are in the
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 SGT 1
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.
Indicators
Troubleshooting
Probable Reason
Corrective Action
1. Symptom: Output changes when doors are closing.
Misaligned detectors.
Align detectors.
The doors are vibrating when closing. Place the detectors further apart from each other.
2. Symptom: Status indicator (Red LED) is constant on.
TX is not emitting.
Check supply and cable to the SGT.
SGT is disabled.
Enable the SGT.
The upper channel is blocked.
Remove obstruction.
2a. For “A1” models (46 mm channel spacing).
More than 4 channels blocked.
Remove obstruction.
2b. For “B1” models (92 mm channel spacing).
More than 2 channels are blocked.
Remove obstruction.
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).
Remove obstruction or prepare to replace the
faulty detector.
3b. On “B1” model (92 mm channel
spacing), up to two non-adjacent channels
have been blocked or damaged
(time-out function activated).
Remove obstruction or prepare to replace the
faulty detector.
4. Symptom: Status indicator (Red LED) is flashing and output is not working.
Two adjacent channels are blocked.
Remove obstruction or replace detectors.
Lower channel blocked
5. Symptom: Output indicator (Yellow LED) is flashing
Severe electrical interference. Remove SGR and SGT supply cable from high
voltage cables.
Severe ambient light. Change position of SGT and SGR.
Cross talk from another light curtain. Change position of SGT and SGR.
Red LED: Status indicator
SGT SGR
Yellow LED: Output indicator
Green LED: Power on indicator
