MOMB transponder badge readers.
MOTB enables control of the automation, by entering one of the memorised
numerical codes on the keypad.
MOMB enables control of the automation by simply placing the memorised
transponder bade close to the automation.
These devices have an individual code, which is recognised and memorised by
the control unit during the phase for learning all connected devices (see para-
graph 4.4).
This prevents an fraudulent attempts to replace a device or use of the automa-
tion by unauthorised persons. For further information, refer to the instruction
manual for MOTB and MOMB.

8.3.4 - STOP Input

The Stop input causes the manoeuvre to stop immediately followed by a short
reverse run. Devices with normally open NO or normally closed NC contact out-
puts, optical devices (Opto Sensors), or devices with 8.2 kΩ constant resist-
ance output such as sensitive edges can be connected to this input. The con-
trol unit, during the learning phase, recognises the type of device connected
and activates a STOP command when any variation in the learnt status occurs.
When set accordingly, more than one device can be connected to the STOP
input, also different from one another;
• Several NO devices can be connected in parallel, with no limit to the number;
• Several NO devices can be connected in series, with no limit to the number;
• Two devices with an 8.2KΩ constant resistance output can be connected in
parallel; multiple devices must be connected "in cascade" with a single
8.2KΩ termination resistance;
• An NO and NC type combination is also possible, placing the 2 contacts in
parallel. In this case, a 8.2 KΩ resistance must be placed in series with the NC

Flashes • Programming of functions in progress.
• If this flashes together with L2 this indicates that the device learning phase must be performed (see paragraph 4.4).
Quick flash After control unit start-up, it indicates a memory error regarding the devices connected. At the same time, the "Bluebus" led emits
a diagnostic signal: 5 flashes - pause of 1 second - 5 flashes. In this case the learning phase for connected devices must be
performed (see paragraph 4.4).
Led 2 Description
Off During normal operation, indicates "Re-close after photo" not active.
On During normal operation, indicates "Re-close after photo" active.
Flashes • Programming of functions in progress.
• If this flashes together with L1 this indicates that the device learning phase must be performed (see paragraph 4.4).
Quick flash After control unit start-up, it indicates a memory error regarding the positions. At the same time, the "Bluebus" led emits a diagnostic
signal: 5 flashes - pause of 1 second - 5 flashes. In this case the learning phase for the Opening and Closing positions must be
performed (see paragraph 4.5).

contact; this also enables the combination of 3 devices: NO, NC and 8.2 KΩ.
Caution – If the STOP input is used to connect devices with safety functions,
only the devices with a constant resistance of 8,2 KΩ or OPTO SENSOR opti-
cal devices guarantee adeguate safety levels against faults.
For connection of an optical device type OPTO SENSOR make the connections
as shown in Figure 51. The maximum current provided on the 12 Vdc line is 40
mA.

8.4 - Diagnostics

Some devices are able to emit signals that serve to recognise their state of
operation or possible faults.

8.4.1 - Signals of control unit

The leds of the terminals and the keys on the control unit (fig. 52) emit special
signals both to indicate normal operation and possible faults. Tables 14 and 15
describe the cause and solution for each type of signal.
Solution
Check for presence of the power supply; check that the
fuses are not blown; in this case, identify the cause of the
fault and then replace with versions with the same
specifications.
This indicates a serious fault; try switching off the control
unit for a few seconds; if the condition persists there is a
fault and the electronic board needs to be replaced.
Normal operation of control unit
A variation to the status of the inputs SS, STOP, OPEN,
CLOSE, activation of the photocells, or when the radio
transmitter is used, is normal.
This is the same signal of 1 second as on the flashing light
(See table 15)
