CONNECTIONS OF THE CN1 TERMINAL BOARD
1: Power supply 12-24 VAC-DC
2: Power supply 0V
3: “Normally open” contact output CH1
4: “Normally open” contact output CH1
5: “Normally open” contact output CH2
6: “Normally open” contact output CH2
INSTALLATION OF THE RECEIVER
It is very important to choose the place of installation carefully
in order for the transmitter and the receiver to function well.
Capacity is not only conditioned by the technical features of the
device, but also varies depending on the radio-electric
conditions of the site. The receiver has a tuned antenna.
The antenna must be positioned where it can be seen well
away from metal structures.
There must be a distance of at least 5 metres between the two
receivers if installation is to be successful.
POWER SUPPLY SELECTION
The power supply voltage can be selected by selection of the
Jumper J1:
Jumper J1: 12/24 VAC-DC power supply selection.
Pos. 1-2 = 12 VAC-DC.
Pos. 2-3 = 24 VAC-DC (default).
CH1 AND CH2 FUNCTIONING METHOD
The receiver can manage the two channels separately and also
allows to have different functioning modes:
Channel CH1: monostable functioning only with possibility
of activation of Long Distance Programming.
Channel CH2: by selecting Switch SW1, it is possible to
select the following functioning modes for channel CH2
(in long distance functioning mode it is monostable).
MONOSTABLE LONG DISTANCE PGM TEMP.120 SEC BISTABLE
(CH1 AND CH2)
PROGRAMMING MODE
The programming of the radio controls to be associated is the
Self-learning type and is performed with the antenna not
connected in the following way: press SEL once, the CODE
CH1 LED, it will start to flash and at the same time sends the
pre-selected code with the radio control to a distance of a few
metres. When the LED remains on, programming in the CH1
channel will be completed. To memorise a radio control code in
channel CH2, perform the same procedure described above
and pressing the SEL key twice.
The memorisation procedure can be repeated up to a max. of
500 codes. When the memory is full by repeating the
programming operation, the CODE CH1 AND CODE CH2
LEDs will start to flash very quickly, indicating that no more
memorisations can take place.
LONG DISTANCE PROGRAMMING METHOD
The long distance programming of radio controls is obtained by
selecting Dip Switch SW1 in long distance Pgm mode. In this
way the receiver allows programming of the transmission code,
without intervening directly on the SEL key.
The long distance transmission code is programmed as follows:
send a radio control code, previously-memorised in a channel,
continuously for longer than 10 seconds. At the same time the
receiver will enter the programming mode, as described below,
for both channels.
RESET
If the receiver must be restored to factory configuration (i.e. no
code memorised), press the SEL key continuously for 5
seconds. The CODE CH1 and CODE CH2 LEDs will flash three
times quickly and then switch-off.
