GB How to use IR-8M/16M 24V/120/230V
Description
IR-8M/16M 24V/120/230V is an 8/16-channel programmable IR receiver with
8/16 alternating relay switches. The receiver can be programmed with all
GewaLink channels, 4096 codes and Infra-code. The receiver relays can inde-
pendently be set for bistable (latching) or monostable (non-latching) function.
Detector Connection
The wires are colour-coded. Connect the wires as in the figure. If older types of
detectors without yellow leadings are connected, a resistor at each detector input
has to be removed. (Please contact GEWA for further information). Be careful
when connecting the leadings! Making the wrong connection may damage the
equipment. It is possible to connect up to two detectors. NOTE! The range is
reduced if the detector eye is covered or in any other way obscured by curtains
or furniture for example.
Relay Connection
The receiver has 8/16 voltage-free alternating relay switches which are
connected according to the figure. See technical data for max relay load. When
connecting inductive loads, motors and relays for instance, an interference
suppression device should be used. In order to meet the isolation requirements
when connecting both extra low and low voltage, there must be a distance
between these leadings that corresponds to one relay output (3 terminal blocks).
Alternatively, connect extra low and low voltage to different circuit boards
(applies to IR-16M). The leadings for extra low voltage shall have the same
isolation level as the low voltage leadings. Extra low voltage leadings can also
be protected by additional isolation.
Fuse
The in- and output on the IR-receiver must be externally protected by a 10 A
fuse in a fuse box.
Supply Voltage
The supply voltage of the receiver should be 24 V AC/DC (+/-20%), or 120/ 230
V AC. See instructions near the power supply terminal blocks. NOTE! The
power must be switched off when changing fuses or in any other way
working on the receiver.
