Flash Warning light
Output for warning light mounting a 12 V (maximum 21 W) lamp. The
output can be programmed (refer to the “ Level 1 programming (ON-
OFF) ” paragraph).

cable
Bluebus BlueBus
Input for compatible devices (MOFB, MOFOB, MOB and MOTB). The
devices must be connected in parallel through two conductors carrying
both the power supply and the communication signals. It is not necessary
to observe the pole markings. During the learning function, each device
connected to the control unit will be individually recognised thanks to a
univocal code. Whenever a device is added or eliminated, the control unit
must run the learning procedure (see “ Learning of connected devices ”
paragraph).

Stop Stop
CONFIGURATION 1:
Input for devices that through their intervention trigger the immediate
stoppage of the current manoeuvre followed by a brief reversal. NO
(normally open) contacts, NC (normally closed) contacts or devices with
8.2 kΩ fixed resistor output, such as sensitive edges, can be connected
to this input. Each device connected to this input will be individually
recognised by the control unit during the learning phase (see “ Learning
of connected devices ” paragraph). During this phase, if the control unit
detects any variation with respect to the learned status, it triggers a STOP.
One or more devices, even different from one another, can be connected
to this input: any number of NO inputs in parallel; any number of NC inputs
in series; 2 devices with 8.2 kΩ fixed resistor output in parallel. If there
are more than 2 devices, they must all be connected in cascade mode
with a single 8.2 kΩ terminating resistor; 2 NO and NC devices in parallel,
putting an 8.2 kΩ resistor in series with the NC contact (this also allows for
combining 3 devices: NO, NC and 8.2 kΩ).
CONFIGURATION 2:
Closes motor 2.
1 x 0.5 mm

SbS
Step-by-step
CONFIGURATION 1:
Input for a NO (normally open) button, for sending commands in step-by-
step mode.
CONFIGURATION 2:
Opens motor 2.
1 x 0.5 mm

Open Open
CONFIGURATION 1:
Input for command devices that trigger the opening manoeuvre only, when
they intervene. NO (normally open) contacts can be connected to this
input.
CONFIGURATION 2:
Closes motor 1.
1 x 0.5 mm
2
Close Close
CONFIGURATION 1:
Input for command devices that trigger the closing manoeuvre only, when
they intervene. NO (normally open) contacts can be connected to this
input.
CONFIGURATION 2:
Opens motor 1.
