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

on the slave board.
The electrical connection provides for the two automation systems to communicate via the 2Easy BUS using a polarised connection:

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 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 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 repeatedly press the Fbutton until you reach the parameter
+ 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 movement.
6.
On 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 automation system
shown on the display of both automation systems is

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
