3) If using buffer batteries, secure the relevant support in
position B with four Ø3.5x9.5 self-tapping screws
(supplied) in the crossover holes of the guides of the
sealed enclosure. NB.: the support is sized to house 2
batteries (not supplied) with characteristics and
dimensions specified on the table in paragraph 2.
4) Position the batteries on the support.
5) Secure the control unit in position C with four Ø4.2x13
self-tapping screws (supplied), placing the spacers
between the board and the guides of the sealed
enclosure.
Procedure for securing the encoder on the gearmotor
(Fig.2):
1) Using the four Mx10 screws C (supplied), secure board B
on cover A, locating the spacers D between cover
and board.
2) Using the M4x30 screw F (supplied), secure encoder E directly on the thread on the rotor of the gearmotor.
3) Wire up terminal board G as described below.
4.1
TERMINAL BOARD M1
4.1.1 Earth
Dedicated terminals or mass cable. Connect earth to a 115/230V~ source.
N.B.: this connection is absolutely necessary for a proper functioning of the control bord.
4.1.2 22V power supply
Terminals "1-2". This is the input to which the secondary winding of the transformer, powered at 22 V~ 50/60 Hz, should be
connected. When power is supplied by the transformer, this is signalled by the POWER LED lighting up.
4.1.3 Batteries
Terminals "3-4". The control unit is designed to operate with two floating batteries (optional item) with minimum characteristics
as indicated on the table in paragraph 2. When powered, the control unit keeps the batteries charged. The batteries begin
to operate when the transformer no longer supplies power.
N.B.: power supplied by batteries should be considered an emergency situation – the minimum number of gate operations
is about 10/15. In any event, the number of possible operations depends on the quality of the batteries, structure of gate,
and time elapsing since mains power failed, etc, etc..
N.B.: observe the power polarity of the batteries
4.1.4 Accessories
Terminals "5-6". Output for powering external accessories (24 Vdc).
N.B.: Maximum load of accessories is 500 mA.
4.2
TERMINAL BOARD M2
4.2.1 Gearmotor
Terminals "7-8". Connect the motor to a power supply of 24Vdc 70W max.
4.2.2 Flashlight
Terminals "9-10". Use a flashing-light with steady light (flashing is produced by the control unit) on operating voltage of 24
Vdc 15W max. It is useful to connect it before programming, as it indicates its phases. It produces a pre-flashing steady light
for 0.5 seconds when opening, and for 1.5 seconds when closing. If the automatic logic is ON, when it reaches the opening
stop-point, the flashing-light stays on with a steady light for 5 sec signalling to the user that it will close automatically. When
the gate is open, the flashing-light is OFF, and only flashes when the safety devices are engaged for a maximum time of 10
sec, after which the flashing-light goes OFF even with the safety devices engaged.
4.3
TERMINAL BOARD M3
4.3.1 Encoder
Terminals "11-12-13". Use the encoder supplied with the control unit. Connect the return signal from encoder terminal "11"
to terminal "11", connect encoder terminals "12-13" to terminals "12-13".
NB.: the control unit will not operate without an encoder.
NB.: observe the encoder's cable terminals
4.3.2 Start
Terminals "14-18". Any device (e.g. push-button, remote control, etc.) can be connected to this circuit. By closing a contact,
the circuit generates a pulse for total opening and/or closing of the gate. Its operating mode is set by dip-switch 3 – see the
relevant paragraph.
N.B.: a START pulse during the pedestrian stage always has priority over that stage
N.B.: to install several pulse generators, connect the contacts in parallel.
4.3.3 For pedestrian use
Terminals "15-18". Any device (e.g. push-button, remote control, etc.) can be connected to this circuit. By closing a contact,
the circuit generates a pulse for partial opening (30% of total opening ) of the gate.
N.B.: a START pulse during the pedestrian stage always has priority over that stage
N.B.: to install several pulse generators, connect the contacts in parallel.
