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 the window opener Window Master. 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!
