7. INSTALLING THE CONTROL BOARD ENCLOSURE
The MASTER-B board positioning has to be decided before installing the control board enclosures since all accessories will be
connected to this board.
The MASTER-B board can be fitted either on the right or on the left side of the gate. You only have to decide to which leaf it will
be associated as shown in Fig. 5.
In double-leaf applications, the MASTER-B board always commands leaf 1. If you wish to command leaf 1 with the SLAVE-B board,
and leaf 2 with the MASTER-B board, you have to program the system in the appropriate way. (refer to chapter 12.4.1).
NB.: Leaf 1 is always the leaf that starts first on opening and is delayed on closing.
Leaf 2
SLAVE-B board
Install the enclosures of the MASTER-B control board (to which all accessories and pulse generators will be connected) and the
SLAVE-B units near the DOMO operators using 4 expansion bolts and their fixing screws. Route the electric cables to the bottom
of the box using adequate rigid and/or flexible tubes and proper joints (Fig. 6).
Leave the cables inside the enclosure lengthy enough to enable you to wire up.
NOTE:
TO ENSURE CORRECT OPERATION OF THE SYSTEM, DO NOT, FOR ANY REASON, EXTEND OR MODIFY THE OPERATOR
CABLES.
BEAR THIS IN MIND BEFORE INSTALLING THE ENCLOSURES.
