3.6) Description of the electrical connections

The following is a brief description of the electrical connections; for
further information please read "7.3 Adding or Removing Devices"
paragraph.
FLASH: output for one or two "LUCYB" or similar type flashing
lights with single 12V maximum 21W bulb.
S.C.A.: "Open Gate Light" output. An indication lamp can be con-
nected (24V max. 4W). It can also be programmed for other func-
tions; see paragraph "7.2.3 Level two functions".
BLUEBUS: compatible devices can be connected up to this ter-
minal. They are connected in parallel using two conductors only,
through which both the electricity supply and the communication
signals travel. For more useful information about BLUEBUS see
also Paragraph "7.3.1 BLUEBUS".
STOP: input for the devices which block or eventually stop the
manoeuvre in progress. Contacts like "Normally Closed", "Normally
Open" or constant resistance devices can be connected up using
special procedures on the input. For more useful information about

4) Final checks and start up

The manufacturers recommend you position the leaf at approximately half travel before starting the checking and start up phase of the auto-
mation. This will ensure the leaf is free to move both during opening and closure.

4.1) Choosing the direction

The direction of the opening manoeuvre must be chosen depending
on the position of the gearmotor with respect to the leaf. If the leaf
must move left for opening, the selector must be moved towards
left as shown in Figure 18; alternatively, if the leaf has to move right
during opening, the selector must be moved towards the right as
shown in Figure 19

4.2) Power supply connection

!
The connection of ROBUS to the mains must be made
by qualified and experienced personnel in possession of the
necessary requisites and in full respect of the laws, provisions
and standards currently in force.
As soon as ROBUS is energized, you should check the following:
1. Make sure that the "BLUEBUS" LED flashes regularly, with about
one flash per second.
2. Make sure that the LED's on the photocells flash (both on TX and
RX); the type of flashing is not important as it depends on other
factors.

4.3) Recognition of the devices

After connecting up the power supply, the control unit must be made to recognise the devices connected up to the BLUEBUS and STOP
inputs. Before this phase, LEDs L1 and L2 will flash to indicate that recognition of the devices must be carried out.
1. Press keys [s] and [Set] and hold them down
2. Release the keys when L1 and L2 LED's start flashing very quickly (after approx. 3 s)
3. Wait a few seconds for the control unit to finish recognizing the devices
4. When the recognition stage is completed the STOP LED must remain on while the
L1 and L2 LED's must go off (LEDs L3 and L4 will eventually start flashing).
The connected devices recognition stage can be repeated at any time, even after the installation (for example, if a device is installed); for
performing the new recognition see paragraph "7.3.6 Recognition of Other Devices".
STOP see also Paragraph "7.3.2 STOP Input".
STEP-BY-STEP: input for devices which control Step-by-Step
movement. It is possible to connect "Normally Open" devices up to
this input.
OPEN: input for devices which control only the opening move-
ment. It is possible to connect "Normally Open" devices up to this
input.
CLOSE: input for devices which control only the closing move-
ment. It is possible to connect "Normally Open" devices up to this
input.
AERIAL: connection input for the radio receiver aerial (the aerial is
incorporated in LUCY B).

3. Make sure that the flashing light connected to the FLASH output
and the lamp LED connected to the "Open Gate Indicator" output
are off.
If the above conditions are not satisfied, you should immediately
switch off the power supply to the control unit and check the electri-
cal connections more carefully.
Please refer to Chapter "7.6 Troubleshooting" for further information
about finding and analysing failures.
