For a synchronized operation of two or more road barriers (up to 7) a main barrier has to be designated (i.e. connected
to the controls) as MASTER by setting dip-switch S5 to "M" (to left).
The other barriers have to become SLAVES by setting S5 to "S" (to right).
To connect two opposite barriers:
The Master barrier operates independently from the Slaves and vice-versa the Slave barriers depend on the Mas-
ter.
The Master barriers must be connected to the input controls and any accessories (e.g. photocells, electrolock, edge,
radio receiver).
To connect three (or more) road barriers:

The Slave barriers MUST only have the limit switches and only if required, inputs STEP BY STEP, OPEN, CLOSE, STOP,
PHOTOC. and EDGE, the battery charger, electrolock, beacon and Barrier Open Light and the dip-switches next to the
terminal block have to be set to ON to inhibit the normally closed inputs (i.e. 1 STOP, 4 PHOTOCELL, 5 EDGE).
N.B.: If the MASTER is programmed with AUTOMATIC CLOSE, the SLAVES must not be enabled.
the MASTER is programmed with Warning, it also has to be programmed on the SLAVES
N.B.: It is best to use a 2x1mm shielded cable for connections and always keep the power cables separate from the
control and serial communication cabling to avoid interference, using 2 individual conduits.
