Master/Slave Configuration - 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 one controlled by the MASTER via the
2Easy BUS.
Setting the two boards as master and slave must first of all be performed
in base level programming by setting the value
Ct SL
board and = on the slave board.
The electrical connection provides for the two automation systems to
communicate via the 2Easy BUS using a polarised connection (see
fi gure).
Any input signals present on terminal J1 of the SLAVE
board will be ignored; connect all control and safety
signals to the MASTER board.
When the BUS connection is made, the SLAVE automa-
tion system will synchronise with the MASTER. Ensure
there are no people or other obstacles in the range of
action of the beam.
To set up the automation systems, proceed as follows:
1. Check that the open/close movement is consistent with the button
pressed (+ / -) on both barriers via the "Mt" parameter of the base
configuration level; if not, the motor wiring must be adjusted by
inverting the two conductors L1 and L3 as shown in Fig. 14, Ref.
2. Bring the automation systems to the fully closed position with the
"Mt" parameter of the Base configuration level or by operating
the release device as indicated in sections 6 and 7 on page 4.
3. Access Base programming on the MASTER device and repeat-
edly press the Fbutton until you reach the parameter
press the + and - buttons at the same time until both automation
systems begin opening slowly.
4. On reaching the fully open position, both automation systems will
stop automatically.
5. The automation systems will then begin the beam closing move-
ment.
6. On reaching the closed position, the movement will stop auto-
matically.
7. Press the F button to exit the procedure, and confirm you wish
to save the data. Check that the current status of the automation
system shown on the display of both automation systems is
(closed) and that the rod is in the closed position. If the rod is open

In MASTER / SLAVE operation mode the two devices will remain
independent in terms of their configuration, the forces and speed of
movement, the loop detectors and configurable outputs.
The MASTER will, however, overwrite the operational logic on the
SLAVE and reading of the SLAVE inputs will be prevented.
When a device is configured as SLAVE, the unused parameters will
be hidden in the programming menus. The following table indicates
the structure of the menus of a board configured as a SLAVE device.
