9.2.5 Learning of other devices
Normally the learning of devices connected to “BlueBUS” and
the “STOP” input takes place during the installation stage; how-
ever, if new devices are added or old ones removed, the learn-
ing process can be redone.
Start the procedure by activating parameter Set 1 (refer to the
chapter “PROGRAMMING“).
m
After having added or removed devices, the auto-
mation test must be carried out again as specied
in the “Testing” paragraph.
9.3 GEARMOTOR IN SLAVE MODE
When properly programmed and connected, the motor can
function in the SLAVE mode; this operating mode is used when
two counterposed barriers must be automated and the barri-
ers must move in a synchronised manner. In this mode, one
motor functions as a MASTER and commands the manoeuvres,
while the second motor functions as a SLAVE, executing the
commands transmitted by the MASTER (all motors devices are
MASTERS by default).
The connection between the SLAVE and the MASTER is made
by connecting terminals 1-2 of the MASTER to terminals 1-2 of
the SLAVE using two cables.
l
It is not important which motor functions as MAS-
TER or SLAVE; the choice must take into account
the ease of the connections and the fact that the
“Step-by-Step”, “Open” and “Close” commands on
the SLAVE device allow for commanding the SLAVE
barrier only.
Perform the following operations to install two motors in MASTER
and SLAVE mode:
1. install the two motors
2. connect the two motors as shown in “Figure 47”
3. select the direction of the opening manoeuvre of the two
motors (see paragraph “Choosing the direction“)
4. make the other electrical connections (refer to the chapter
“ELECTRICAL CONNECTIONS“)
5. power the two motors (see paragraph “Power supply
connection“)
6. in the SLAVE barrier:
– perform learning of the connected devices (see para-
graph “Device learning“)
– perform learning of the opening and closing positions
(see paragraph “Learning of the mechanical stop po-
sitions“)
– adjust the force and speed
– activate the “SLAVE mode” parameter (refer to the
chapter “PROGRAMMING“)
– error “E5” will appear to signal a Master-Slave commu-
nication error, because the MASTER barrier has not yet
been paired with the SLAVE barrier
m
Bear in mind that during operation all the settings
made on the SLAVE barrier are ignored, since those
made on the MASTER barrier prevail, with the ex-
ception of the speed, slowdown speed, slowdown
position and force settings, which have an impact
on the SLAVE barrier only.
7. in the MASTER barrier:
– perform learning of the connected devices (see para-
graph “Device learning“)
– perform learning of the opening and closing positions
(see paragraph “Learning of the mechanical stop po-
sitions“)
8. send a command from the MASTER control unit to com-
plete a manoeuvre and verify that it is carried out also by
the SLAVE barrier.
In connecting the two motors in SLAVE-MASTER mode, verify
that:
– all devices must be connected to the MASTER motor (as
shown in “Figure 47”), including the radio receiver
– when using back-up batteries, each motor must have its own
battery
On the SLAVE motor it is possible to connect:
– an own warning light (Flash)
– an own Open Gate Indicator (OGI)
– boom lights
– an own sensitive edge (Stop)
– own control devices (SbS, Open and Close) that command
the SLAVE barrier only
– the Loop1 and Loop2 inputs programmed with the “Open”
and “Close” modes.
