GB: English Instructions for Use GL-4M WM
Description
GL-4M is a programmable IR receiver with four relay outputs with alternating relay
contacts. The receiver has been modified to be used for window openers. The
receiver can be programmed with all GewaLink channels and one coded channel
(4096). The receiver's relay can be programmed to function in a bistable or a
monostable manner. The IR receiver has an internal IR detector that can be
disconnected.
Connections
All connections are attach by jacks, so that the connectors can be removed before
connecting wires.
The broken lines are links made in production underneath the circuit board.
The figure shows how wires are to be connected.
External Detector
The detector is the actual eye that receives the IR signal. A maximum of two external
detectors can be connected at the same time. There is an internal detector on the
circuit board of the receiver. This detector can be disconnected by cutting off the
lines on the circuit board. This is shown in the figure.
The colours of the wires are to be connected as shown in the figure when connecting
a detector. Make sure that the wires are correctly connected when connecting a
detector.
Note: the range will be reduced if the detector eye is covered or hidden in some way,
for example by curtains or by furniture.
Relay Connection
The receiver has four relays with alternating relay contacts. The maximum relay
loading is specified in the Technical Specifications.
Power Supply
The IR receiver and the window opener are supplied by 18V DC. Connect enclosed
power supply. Note the polarity!
