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.
Mount the transmitter (SGT) and receiver (SGR) facing each other and correctly
1 aligned. Telco recommends that the rails are placed at least 5mm from edges for
mechanical protection.
Wire the sensor according to the wiring diagram. Make sure the load does not
2
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.

Probable Reason
1. Symptom: Status indicator (Red LED) on SGR is constant on.
TX is not emitting
SGT is disabled
The lowest beam is blocked
2. Symptom: Output indicator (Yellow LED) is flashing
Severe electrical interference
Severe ambient light

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
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 is longer than T
r
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
Maximum speed of the blanking object
There is no restriction on maximum speed when removing the object.
Note: Refer to "SGR blanking function response time" & graph.
