Relay Connection; Power Supply; Programming - Gewa GL-4M Mode D'emploi

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. Inductive loads, such as
motors and relays, should be connected through a disturbance filter.

Power Supply

The receiver is powered with 12 - 24 VAC/DC (-10% - +20%).

Programming

The IR receiver can be programmed with GewaLink channels 0-127 (channel 62
has no function) or one coded channel (4096). There is one programming button
for each relay. The selection is also made during programming whether a
particular relay is to function in a monostable or a bistable manner.
Monostable functioning = The relay is activated as long as the key on the IR
transmitter is held down.
Bistable functioning = The relay is activated when the key on the IR transmitter
is held down and releases. The second time the key is held down and released,
the relay will be deactivated.
Program the receiver as follows:
Press the selected button on the IR transmitter and press at the same time one of
the programming buttons on the IR receiver. If the programming button is held
down for approximately 1 second, the unit is programmed with a monostable
function. If it is held down for approximately 2 seconds, the unit is programmed
with a bistable function.
The receiver confirms the programming by activating the relay and causing the
