Introduction:
ST-DOT-120 is an opto-electronic amplifier module for DIN-rail
mounting for use with DOT transmitters and receivers.
It is a single channel amplifier with relay output made for a variety of
supply voltages. It is quick and easy to install. Just connect power,
transmitter, receiver and output and it is ready to operate.
When transmitter and receiver do see each other the relay will be
standing N.O. When the light is interrupted the relay will switch to N.C.
Wiring:
Install receiver closest to the ST-DOT
120. (White wire)
Avoid running any wires close/in
parallel to any motor power cables i.e.
the output from a frequency inverter
drive.
Always use M15 type receiver when
using with frequency inverter
Avoid installing the receiver in direct
sunlight.

Alignment of photocells
During installation make sure that the transmitter and receiver are horizontally
aligned as illustrated below. The photocells can work with a slight offset
(depending on the distance in-between) but this is not recommended as the
sensitivity is affected.
The LED - Relay State will flash green when signal is OK and red if not OK. The green led will
flash faster the more signal there is present.
Installation of photocells
Drill a Ø13mm hole.
Install the photocell bracket and fasten
it bracket with two screws
Install the Photocell in the bracket so
that it is flush with the wall

Troubleshooting:
In case the photocells does not work as intended during day check if the
receiver is exposed to direct sunlight.
If this is the case try swapping the transceiver and receiver.
