Note 2 – If the Bluebus cable is longer than 20 m (up to max. 40 m), a cable with a larger cross-section is required (2 x 1 mm
Note 3 – These 2 cables can be replaced by a single 4 x 0.5 mm
Note 4 – These 2 cables can be replaced by a single 5 x 1.5 mm
IMPORTANT! – The cables used must be suited to the installation environment.

FLASH output for 1 flashing light with 12V (maximum 21W) bulb. [*]
ELS output for 12Vac (maximum 15VA) electric lock. [*]

input for compatible devices (MOFB, MOFOB, MOB and MOTB); they are connected in parallel using two conductors through which both the electricity supply and
the communication signals travel; no polarity needs to be observed. The electrical connection to be used is of the parallel type and no polarity needs to be observed.
BLUEBUS
During the learning stage, the control unit will recognise individually all devices connected to it thanks to a unique code. Each time a device is added or eliminated, it
will be necessary to make the control unit perform the learning operation (see paragraph 3.6).
input for devices that cause the immediate interruption of the manoeuvre in progress (with a short reverse run); NO and NC contacts, as well as devices with 8.2 kΩ
constant resistance output (sensitive edges) can be connected to this input. Each device connected to this input is recognised individually by the control unit during
the learning stage (paragraph 3.6); in this stage, if the control unit detects any variations with respect to the learned state, it causes a STOP. One or more devices of
the same or different kinds can be connected to this input:
– connect a number of NO devices in parallel without quantity limits;
STOP
– several NC devices can be connected in series, with no limits as to quantity;
– connect 2 devices with 8.2 kΩ constant resistance output in parallel. If there are more than 2 devices, they must be connected in a cascade with just one 8.2 kΩ
termination resistance;
– connect 2 NO and NC devices in parallel, placing a 8.2 kΩ resistance in series on the NC contact (this also allows for a combination of three devices NO - NC and
8.2 kΩ).
P.P.
input for devices which control Step-by-Step manoeuvres. NO contacts can be connected to this input.
OPEN input for devices which control only opening manoeuvre. NO contacts can be connected to this input.
CLOSE input for devices which control only closure manoeuvre. NO contacts can be connected to this input.
M1 output for gearmotor 1 (terminal 1, 2, 3).
M2 output for gearmotor 2 (terminal 4, 5, 6).
[*] – The FLASH, ELS and S.C.A. outputs can be programmed with other functions (see "TABLE 5 - 1st level functions"; or via Oview programmer, see chapter 7.2).
