External Detector
The detector is the actual eye that receives the IR signal. A maximum of two
detectors can be used at the same time. There is an internal detector on the
circuit board of the receiver. If two external detectors are connected, the internal
detector must be disconnected. This is achieved using a jumper as shown in the
diagram.
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 an alternating relay contact. 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 V AC/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). The selection is also made during
programming whether the IR receiver 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 the
programming button 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
