4. CONNECTIONS AND OPERATION
4.1. TERMINAL BOARD CN1
4.1.1. Power supply 22V
“
VAC-VAC
” terminals. The secondary 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. If no encoder is used, the input need not be jumper connected.
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. If no encoder is used, the input need not be jumper connected.
Attention: In two-motor applications, the encoder must be installed on both motors.
