Master/Slave Configuration - FAAC B680H Manual

9. MASTER/SLAVE CONFIGURATION

If the installation requires 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
master board and = on the slave board.
The master and slave operators communicate via the 2Easy BUS. Connect them as shown below:
MASTER board

BUS
Any input signal 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 automation 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 operators, 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
2. Bring the arm to the fully closed position with the "Mt" parameter of the Base configuration level or by operating the manual release device.
3. Access Base programming on the MASTER device and repeatedly press the F button until you reach the parameter
the + and - buttons at the same time until both operator arms begin opening slowly.
4. Upon reaching the fully open position, both operators will stop automatically.
5. The operators will then begin the beam closing movement.
6. Upon reaching the closed position, the movement will stop automatically.
7. Press the F button to exit the procedure, and confirm you wish to save the data. Check that the current status of the operators shown
00
on both displays is (closed) and that the arm is in the closed position. If the arm is open and the display is showing
adjust the correct direction of movement of the motor again as in step 1 of the procedure.

In MASTER / SLAVE operation mode the two devices will remain independent in terms of their configuration, the forces and speed of move-
ment, 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 configuration menus. The following table indicates the
structure of the menus of a board configured as a SLAVE device.
