ELECTRICAL CONNECTIONS

4

IMPORTANT!

 – All electrical connections must be made while discon-

nected from the grid and the buffer battery (if any).

01.

 Insert all the cables for connecting up the devices, leaving them 20 to 30 

cm longer than necessary. Refer to table 5 for the cable type and figure 2 

for connections.

02.

 Use a clamp to hold together all the cables that enter the gearmotor, and 

place the clamp underneath the hole through which the cables enter.

03.

 Connect up the power cable to the terminal provided, as shown in figure 11, 

then use a clamp to lock the cable onto the first cable ring.

04.

 Connect up the other cables as shown in figures 12 and 13. Terminals are 

removable for greater convenience.

05.

 After making connections, lock the cables you have collected together in 

place using the rings provided (fig. 12), and anchor the excess part of the 

antenna cable to the other cables.

To connect up 2 motors on opposite doors, refer to section “8.1.5 NAKED in 

Slave mode”.

.1 - Description of electrical connections

• FLASH

 = output for one or two “LUCYB” or similar type flashing lights with 

single 12V maximum 21W bulb.

• 

OGI

 = Open Gate Light” output. An indication lamp can be connected (24V 

max. 4W). It can also be programmed for other functions; see paragraph “7.4 

Level two functions”.

• 

BLUEBUS

 = compatible devices can be connected up to this terminal. They 

are connected in parallel using two conductors only, through which both the 

electricity supply and the communication signals travel. For more useful infor-

mation about BlueBUS see also Paragraph “8.1.1 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 STOP see also Paragraph “8.1.2 

STOP Input”.

• 

Sbs

 = 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 movement. It is 

possible to connect “Normally Open” devices up to this input.

• 

CLOSE

 = input for devices which control only the closing movement. It is 

possible to connect “Normally Open” devices up to this input.

• 

AUX_IN (Auxiliary Input) 

= input for devices that block or stop the mano-

euvre in progress; Normally Closed (NC) contacts can be connected to this 

input; using Oview, the input function can be changed; the input is factory 

configured to ALT.

• 

AERIAL

 = aerial connection input for radio receiver; the aerial is incorporated 

in the flashing light; alternatively, an external aerial can be used.

The manufacturers recommend you position the leaf at approximately half tra-

vel before starting the checking and start up phase of the automation. This will 

ensure the leaf is free to move both during opening and closure.

5.1 - 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, 

alternatively, if the leaf has to move right during opening, the selector must be 

moved towards the right as shown in Figure.

FINAL CHECKS AND START UP

5.2 - Power supply connection

IMPORTANT!

 – The connection of NAKED 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 cur-

rently in force.

As soon as NAKED is energized, you should check the following:

01.

 Make sure that the “BLUEBUS” LED flashes regularly, with about one flash 

per second.

02.

 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.

03.

 Make sure that the flashing light connected to the FLASH output and the 

lamp LED connected to the “Open Gate Indicator” (OGI) 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 electrical connections more 

carefully.

Please refer to Chapter “9.1 Troubleshooting” for further information about find

-

ing and analysing failures.

5.3 - Recognition of the devices

After connecting up the power supply, the control unit must be made to reco-

gnise 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.

01.

 Press  keys 

[

s

]

 and 

[Set] 

and 

hold them down.

02.

 Release the keys when L1 and L2 

LED’s start flashing very quickly 

(after approx. 3 s).

03.

 Wait a few seconds for the control 

unit to finish recognizing the devi-

ces.

04.

 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 “8.1.6 Recognition of Other Devices”.

5.4 - Recognizing the length of the leaf

After recognizing the devices, L3 and L4 LED’s start flashing; the control unit 

must recognize the length of the gate. During this stage, the length of the leaf 

is measured from the closing limit switch to the opening limit switch. This mea-

surement is required to calculate the deceleration points and the partial opening 

point.

01.

 Press  keys 

[

s

]

 and 

[Set] 

and 

hold them down

02.

 Release the keys when the ma n-

oeuvre starts (after approx. 3 s)

03.

 Check the manoeuvre in pro-

gress is an opening manoeuvre. 

Otherwise, press the 

[Stop]

 key 

and ca refully check Paragraph 

“5.1 Choosing the Direction”, 

then re peat the process from 

Point 1.

04.

 Wait for the control unit to open 

the gate until it reaches the ope-

ning limit switch; the closing 

ma noeuvre will start immediately 

af ter wards.

05.

 Wait for the control unit to close 

the gate.

If the above conditions are not satisfied, you should immediately switch off the 

power supply to the control unit and check the electrical connections more 

carefully. For more useful information see also chapter “9.1 Troubleshooting”.
If it is necessary to adjust limit switch positions more finely, use the 2 adjust-

ment knobs (

fig. 14 

and

 15

) in the gearmotor, as follows:

01.

 Press 

s

 or 

t 

on the unit to open or close the leaf on the basis of the posi-

tion to be defined.

02.

 Remove the cover locking the 2 adjustment knobs (

fig. 14

).

03.

 Identify the adjustment knob with the arrow indicating the direction of the 

limit switch to be adjusted and turn it half a turn (about 3 cm travel of the 

gate) 

fig. 15

.

04.

 Next, on the unit, press 

s

 or 

t 

again to open or close the door to adjust 

the new position. Repeat as necessary until the door has the desired limit 

switch.
