4. CONNECTIONS AND OPERATION

4.1. TERMINAL BOARD CN1

4.1.1. Power supply 22V

“VAC -VAC” terminals. The secondar y circuit of the 24V~ 50/60 Hz transformer should be connected to this input. Power supplied by the
transformer is signalled by the lighting of the “ALIM” LED located under the terminal board.

4.1.2. Batteries

“+BAT - -BAT” terminals. Connect the power cables of the buffer batteries (optional) to these terminals. The control unit is designed to
operate with two buffer batteries, with the minimum characteristics shown on the table in paragraph 2. During normal operation, the unit
keeps the batteries charged and these start operating if no power is supplied to the transformer.

N.B.:

• Power supplied by batteries only should be considered an emergency situation. The number of possible manoeuvres is linked to the

quality of the batteries, the structure of the gate to be moved, the time elapsed since power cut occurred, etc, etc.

• Observe the battery power supply polarity.

4.1.3. Accessories

“+24V - -24V” terminals. The accessories power cables should be connected to these terminals.

N.B.:

• The maximum load of the accessories must not exceed 500 mA.

• The output of these terminals is DC - observe the power supply polarity of the accessories.

4.1.4. Earth

“ “ terminal. The control unit earthing cable should be connected to this terminal.

N.B.:

• This connection is absolutely necessary to ensure a correctly operating control unit.

4.2. TERMINAL BOARD CN2

4.2.1. Gearmotor 1

“APM1 - CHM1” terminals. For double leaf applications, connect to these terminals the gearmotor fitted on the leaf which must move
first. For single leaf applications, the gearmotor must be connected to these terminals. The maximum load of the gearmotor must not
exceed 70W.

4.2.2. Gearmotor 2

“APM2 - CHM2” terminals. For double leaf applications, connect to these terminals the gearmotor fitted on the leaf which must move last.
For single-leaf applications, nothing should be connected to these terminals. The maximum load of the gearmotor must not exceed 70W.

4.2.3. Electric lock

“ELS - ELS”terminals. The electric lock, if any, with 12 Vdc/~ power supply, should be connected to these terminals. To facilitate release of
the electric lock, the over-pushing stroke can be input by enabling parameter “F” (see paragraph 9).

N.B.:

• In double-leaf applications, install the electric lock on the leaf where gearmotor 1 is installed.

4.2.4. Flashing lamp / Courtesy light

“LAMP - LAMP” terminals. Both a flashing lamp and a courtesy light can be connected to these terminals, both with 24 Vdc power supply
and maximum 15W. To make this output operational, select parameter “G”, see paragraph 9.

Flashing lamp operation:

During normal operation, the flashing lamp provides a fixed pre-flashing of 1.5 seconds during both opening and closing. When the gate
is open, and the closing safety devices are tripped, the lamp flashes to indicate that a manoeuvre is taking place in the gate movement
area. We advise you to connect the flashing lamp before programming, because it indicates its phases. Use a fixed light flashing lamp;
flashing is controlled by the control unit.

Courtesy light operation:

The courtesy light stays lighted for a fixed time of 90 seconds from the OPEN pulse, after which it goes OFF. Use a lamp with 24 V power
supply and maximum 15W.

4.3. TERMINAL BOARD CN3

4.3.1. Motor 1 closing limit-switch

“COMF - FCC1” terminals. Normally closed contact. This is tripped and stops the closing motion of motor 1. The status of this input is signalled
by LED FCC1.

4.3.2. Motor 1 opening limit-switch

“COMF - FCA1” terminals. Normally closed contact. This is tripped and stops the opening motion of motor 1. The status of this input is
signalled by LED FCA1.

4.3.3. Motor 2 closing limit-switch

“COMF - FCC2” terminals. Normally closed contact. This is tripped and stops the closing motion of motor 2.The status of this input is signalled
by LED FCC2.

4.3.4. Motor 2 opening limit-switch

“COMF - FCA2” terminals. Normally closed contact. This is tripped and stops the opening motion of motor 2. The status of this input is
signalled by LED FCA2.

N.B.:

• If no limit-switch is used, jumper connect the inputs.

• The limit-switches cannot be used as the start of the decelerated section.

4.3.5. Motor 1 encoder

“ENC1” terminal. The signal received from the encoder installed on gearmotor 1 must be connected to this terminal. For operation and
activation of the encoder, see paragraph 6.

N.B.: If no encoder is used, do not, on any account, jumper-connect the inputs.

4.3.6. Motor 2 encoder

“ENC2” terminal. The signal received from the encoder installed on gearmotor 2 must be connected to this terminal. For operation and
activation of the encoder, see paragraph 6.

N.B.: If no encoder is used, do not, on any account, jumper-connect the inputs.
Attention: In two-motor applications, the encoder must be installed on both motors.

4.4. TERMINAL BOARD CN4

4.4.1. Total opening

“COM - OPEN A”terminals. Normally open contact. Connect, to these terminals, any pulse generator (e.g. push-button, key selector, etc.)
which, by closing a contact, generates a gate total opening or closing pulse. The operation of this generator is defined by parameter “D”,
see paragraph 9.

N.B.:

• A total opening pulse always has priority over pedestrian opening.

• To connect several pulse generators, connect the devices in parallel.

4.4.2. Pedestrian opening

“COM - OPEN B” terminals. Normally open contact. Connect, to these terminals, any pulse generator (e.g. push-button, key selector, etc..)
which, by closing a contact, generates a gate partial opening or closing pulse. In double leaf applications, pedestrian opening corresponds
to total opening of leaf 1. In single leaf applications, pedestrian opening corresponds to about 30% of memory-stored total opening.

N.B.:

• A total opening pulse always has priority over pedestrian opening.

• To connect several pulse generators, connect the devices in parallel.

4.4.3. Stop

“COM - STOP” terminals. Normally closed contact. Connect, to these terminals, any safety device (e.g. pressure switch, safety edge, etc.)
which, by opening a contact, immediately stops the gate and disables all automatic functions. The status of this input is signalled by the
“STOP” LED. The gate resumes its memory-stored cycle only by means of another total or partial opening pulse.

N.B.:

• If no STOP devices are connected, jumper connect the input.

• To connect several STOP commands, connect the devices in series.

4.4.4. Closing safety devices

“COM - FSW CL”terminals. Normally closed contact. Connect, to these terminals, any safety device (e.g. photocell, safety edge, pressure
switch etc..) which, by opening a contact, affects the gate's closing motion, reversing it to the mechanical stop, or to the opening limit­switch. The status of this input is signalled by LED “FSW-CL”.

4.4.5. Opening safety devices

“COM - FSW OP”terminals. Normally closed contact. Connect, to these terminals, any safety device (e.g. photocell, safety edge, pressure
switch etc..) which, by opening a contact, affects the gate's opening motion, causing it to stop immediately. When the safety device has
been reset, the gate resumes its memory-stored cycle. The status of this input is signalled by LED “FSW-OP”.

N.B.:

• If no safety devices are connected, jumper connect the inputs.

• To connect several safety devices, connect the devices in series.

The control unit is designed to house a 5-pin radio-receiver module. Installation procedure: turn off power and fit the module in connector

CN5 on the control unit.

ATTENTION: To avoid damaging the receiver and thus irreparably compromising its operation, the receiver must be installed while

observing the fitting direction specified in paragraph 13 (connection lay-out).

This done, observe the radio-receiver instructions to store the radio control in the memory.

6. OPERATION WITH ENCODER OR AMPEROMETRIC OPERATION

The control unit has 4 DIP SWITCHES, which enable selection of either amperometric operation or operation with Encoder.

Operation with encoder provides greater safety in detecting obstacles and greater repeatability of the deceleration point.

N.B.: Operation with encoder requires mechanical stops, or limit-switches, for both opening and closing.

To select operation with encoder, position DIP-SWITCHES 1 and 2 to ON and DIP-SWITCHES 3 and 4 to OFF (Fig.02).
To select amperometric operation, position DIP-SWITCHES 1 and 2 to OFF and DIP-SWITCHES 3 and 4 to ON (Fig.03).

ATTENTION: For a correct programming procedure of the control unit, carry out this operation before programming the control unit

because it radically modifies its operation.

10. PROGRAMMING

N.B.:

• Before you begin programming, select the type of operation for the control unit: with or without encoder (see paragraph 6).

During the programming procedure, the control unit memory-stores the opening, closing mechanical stop points and any pause time
before re-closure.

1- Release the gearmotors, locate the leaves at half open point, and re-lock the operators.
2- Power up the control unit and check if value “ ” is shown on the display.
3- Press and hold down push-button P2 until the display shows the first parameter and relevant value.
4- Give an OPEN A command with any device connected to this input: the display shows value “ ”, and the leaves begin to move.

The first manoeuvre performed by the leaves must be closing. If this does not happen, stop the gate movement with a reset pulse. To

do this, make a bridge between the two “RESET” PINS, using the connector (see Fig.5). Cut

power and put the connector back in its normal position (Fig. 5). Then change over the

wires of the motor/s, which had performed the opening operation. Resume the

programming stage from point 1.
5- When the closing mechanical stop point is reached, the gearmotors pause for about 2

seconds, and then restart with a total opening manoeuvre up to the opening mechanical

stop point or up to the relevant limit-switch.
6- If automatic reclosure was not enabled, this means programming has finished, otherwise

the control unit begins counting pause time.
7- When the required time has elapsed, give another OPEN A pulse, and the gate will begin

to close.
8- When the closing stop has been reached, programming has terminated, and the display

shows value “ ”.

N.B.:

• The display shows value “ ” during the entire programming procedure.

• The flashing lamp stays lighted on a fixed light during the entire programming time.

• Leaf movement is decelerated during the programming procedure.

Fig. 5

This is a very important device for reasons of safety. Its setting stays unchanged long-term, without wear. It is active during both closing and
opening. When it operates, it reverses gate movement without disabling automatic closing if activated.
If the clutch operates several consecutive times during the closing movement, the control unit goes into STOP status, disabling any
automatic command. If the clutch operates several consecutive times, this means that the obstacle remains and it could be dangerous
to perform any manoeuvre. To restore normal operation, the user must give an OPEN A / OPEN B pulse.
