Installation & Adjustments
Installation and Adjustment
No initial set up or adjustments are required, due the automatic signal-tracking (AST) feature,
which automatically adjust each individual channel on the system.
Notice that the SG14 system must not be placed on moving doors.
1
Mount the transmitter (SGT) and receiver (SGR) facing each other and correctly
aligned. Telco recommends that the rails are placed at least 5mm from edges for
mechanical protection.
2
Wire the sensor according to the wiring diagram. Make sure the load does not
exceed 200 mA.
3
Check for correct wiring. Select blanking function if required.
4
Turn power on.
5
The status indicator (red LED) on the SGR will flash quickly when the AST is active.
6
When the power on indicators (green LEDs) are on, the system is operating.
If the Status indicator (red LED) is constant on the SGR cannot see the SGT.
7
Notice that the rails must not be moved after the power to the SGR is turned on.

Probable Reason
Corrective Action
1. Symptom: Status indicator (Red LED) on SGR is constant on.
TX is not emitting
Check supply and cable to the SGT
SGT is disabled
Enable the SGT
The lowest beam is blocked
Remove obstruction
2. 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

SGT Test Input
SGT Test Input
The transmitter can be externally disabled and enabled via the control wire (black wire) for test
purposes. To activate the test input, please refer to “Transmitter Model” table.
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 its output.
The test input on SGT14 has to be activated a certain minimum time T
r
in order to ensure that
the output of SG14 will switch.
On activation of the SGT14 test input, the output of the receiver will switch within a certain
maximum time T
ON
.
When the test input of SGT14 is deactivated the output will be switched back within a certain
maximum time T
OFF
.
The time T
r
is longer than T
ON
in order to ensure a complete test cycle of minimum duration.
Note:
Refer to “SGT test input response time table” & graph.
SGR Dynamic Blanking Function
Dynamic Blanking Function
All channels can be blanked without switching the output by moving a non transparent object
between the SGR and SGT from top of the rails and down to the lowest channel in one
movement.
All channels will stay blanked as long as the lowest channel at the bottom of the rails is
obstructed. Make sure that the lowest channel is well obstructed when all the channels are
blanked.
Minimum speed of the blanking object
0.05 m/s
Maximum speed of the blanking object
1.6 m/s
There is no restriction on maximum speed when removing the object.
Note:
Refer to “SGR blanking function response time” & graph.
Channel spacing

Minimum size of blanking object
