Installations & Adjustments
Installation
1
Connect the SGR detector to the RX connector input and the SGT detector to the
TX connector input.
2
Connect either AC power supply to the terminals marked 0 and 2, or connect 24 V
dc power supply to the terminals and -. DO NOT turn power on.
Warning:
DO NOT connect AC and DC power supply at the same time
3
Connect terminal to earth or machine frame.
4
Connect to relay on terminal NO, COM, NC or to transistor output on terminal SIG
(signal),
(ground) according to your application. For “safety” relay operation use
NO and COM outputs.
5
Connect to the Alarm and Time-out outputs on terminals AL, TO and
according
to your application.
6
Turn the gain potentiometer to max sensitivity (fully clockwise).
7
Make sure Operation Mode (SW2 DIP-switch nº 2 : OFF) has been selected. Make
sure Long Range has been selected (SW2 DIP-switch nº1 : ON).
8
Turn power on after double checking your wiring, and checking for correct power
supply voltage.
9
If the controller indicates a broken beam despite a clear optical path between the
detectors, switch to Diagnostic Mode. Wait approx. 15 sec. The RXERR and
TXERR LED’s will indicate the faulty detector. Change or clean the faulty detector
and switch to Operation Mode.
10
For operation at ranges below approx. 3 m it is recommended to adjust the
sensitivity, following the calibration procedure below.
Turn the potentiometer to minimum (fully anticlockwise), and then turn slowly
clockwise until the detector see each other. If the adjustment appears too delicate,
then switch to Short Range and re-adjust.
11
In applications with operation at short range it is recommended to use Automatic
Sensitivity Control Mode, to ensure that the light beams easily can be broken. If
there is a need for constant excess emitted power at short range, use Fixed
Sensitivity Mode.
12
Select Relay Mode and time-out according to your application.

Long/Short Range Selection
Long range
Enables the system to operate at 100% (maximum
range). Range up to 5 m.
Short range
Enables the system to operate at 60% of maximum
range. Range up to 3 m.
Diagnostic/Operation Mode SW2
Diagnostic
mode
This switch is only for service. When activated, the
controller initiates a self test. If there is any error in
transmitter or in the receiver, the TXERR LED or
RXERR LED are activated. For instance,
contamination on detectors, bad connections,…

Automatic Sensing/Fixed Sensing SW2
Automatic
Sensing
Control
Automatic Sensitivity Control Mode is
recommended in applications with operation at
short range, to ensure that the light beams easily
can be broken.
Fixed Sensing
Allows to adjust manually the sensitivity of the
system via the potentiometer.
Buzzer On/Off SW2
Buzzer On
Activates the buzzer in parallel with the output.
Buzzed Off
Deactivates the buzzer.
Time-out function SW1
After one or more beams (selectable from 0 to 32) have been broken for more than a preset
period of time (selectable from approx. 15 seconds to 10 minutes) the Controller
will ignore the broken beams, and thus allow the system to operate with the remaining light
beams.
The maximum number of channels time-out can be
selected from 0 to 32 by using the DIP-switches nº 1,2 and
3, on the SW1 switch. Please, refer to Fig. 1
The time-out delay time can be selected from approx. 15
seconds to 10 minutes by using the DIP-switches nº 5,6
and 7, on the SW1 switch. Please, refer to Fig. 1
