Master/Slave Configuration; Interlock Connection - FAAC B680H Manual

9. MASTER/SLAVE CONFIGURATION

If the installation contemplates the gate area being covered by two
opposing barriers, a Master / Slave configuration may be used for
the boards which will activate the two barriers. This configuration
permits connection of the command and safety signals to be simplified
(they are all connected to just one board), also ensuring perfect
synchronisation of the two automated systems.
"MASTER device" means the board to which all the pulse generators
and safety devices are connected.
"SLAVE device" means the board which is controlled by the MASTER
through pulse inputs, while the safety inputs are bypassed.
The electrical connections and the parameters needed for correct
functioning of the system in a Master / Slave configuration are shown
in the following diagram:

10. INTERLOCK
The interlock function enables two in-line barriers to be
managed (see fig.) so that opening of one is subordinated to
closing of the other. Operation can be one-way or two-way.
For in-line barriers, set OUT1 INTERLOCK to parameter 18 (see
2 LEVEL PROG.) on both boards and connect them as in figure.
