7.6 - Master - Slave mode

This operating mode is used if it is necessary to automate 2 counterposed
barriers which perform synchronised movements . In this mode, a barrier works
as Master and commands the manoeuvres, while the second works as Slave
and carries out the commands sent from the Master barrier; by default all the
barriers are set as Master .
To configure the barrier as Slave it is necessary to activate the level 1 function
"Slave Mode" (see Table 7) .
The connection between Master and Slave takes place through the BusT4 with
the dedicated Master/Slave connector .
Important! – Should the Oview programmer be used, it is necessary
to modify the parameter "Griup" or "Address" of one of the 2 barriers.
This is to avoid the simultaneous communication of the 2 control units
with the Oview programmer.

Warnings
• All the devices, including the radio receiver, must be connected on the Master
barrier;
• If the buffer battery is used, each barrier must have its own;
• In the Slave barrier it is possible to carry out the following connections:

- its own flashing light (Flash)
- its own Pole Open Indicator (S .C .A .)
- pole lights
- its own sensitive edge (Stop)
- its own command device (P .P .), which commands the total opening of
the Slave pole only
- the Open and Close inputs are not used
- the Loop1 and Loop2 inputs programmed with "Open" mode
- the receiving radio
To install 2 barriers and program them with "Master - Slave" mode, proceed
as follows:
01. Install the 2 barriers (fig. M) .
It is not important which of the two works as Master or Slave; it is neces-
sary to assess the convenience to create the electrical connections and
that the "Step-Step" command that will carry out the Slave barrier will pro-
vide the total open of the Slave pole only;
02. Connect the two control units one to the other through the Master/Slave
connector (fig. 54), respecting the polarity indicated;
03. At this point, carry out the other electrical connections (fig. 54), referring to
the indications contained in chapter 4 - Electrical connections;
