3.3.2 Synchronism connection
For the Synchronism operation between two Transmitters, it is necessary to interconnect the
terminals 2
“SYNC”
and 1
“GND”
of terminal block MS2 of both Transmitters.
It is also necessary to select one Transmitter as “
Master
” and the other as “
Slave
”, by means of
jumper Jp1.
•
Jp1 =
“IN”
position, the terminal 1 of MS3 is the input for an external synchronism signal,
so the Transmitter is “
Slave
”.
•
Jp1 =
“OUT”
position, the terminal 1 of MS3 is the output for the synchronism signal
internally produced, so the Transmitter is “
Master
”
Remark:
the cable connecting the two transmitters, must be as short as possible and not more
than 10 meters. If cables longer than 10 meters are required, it is necessary to use the
synchronism repetition circuit mod. SYNC 01.
3.3.3 Stand-by connection
For the Stand-by function activation, it is necessary connect to ground the terminal 5 “STBY” of
MS2 terminal block for the receiver circuit and connect to ground the terminal 7 “STBY” of MS4
terminal block for the transmitter circuit.
Remark:
the Stand-by operation, doesn’t inhibit the barrier functionality, but deactivate the record
of events into “historical file” (TX and RX) and in the monitor file (RX).
3.3.4 Test connection
The Test function will be activated connecting to ground the terminal 5 “TEST” of the terminal
block MS2 on Transmitter circuit. If the test procedure is successful done, the alarm relays on
Receiver circuit will be activated later 10 second.
Remark:
for high risk protection it’s necessary a Periodic Test for the equipments. By means for
these control panel will be able to detect tamper action. For the Test function activation
it witch have CORAL-Test instrument; it’s possible to test the microwave barrier,
temporary switching-off the transmitter.
