7.4 FUNCTIONAL CHARACTERISTICS

OPERATION:
When either the remote or the low voltage pushbutton panel are used to
control the barrier, operation is as follows:
the first command opens the barrier until motor time elapses or the arm
reaches its opening limit position; the second command closes the barrier;
if another command is transmitted during the Opening movement, the
control unit disregards the command; if a command is transmitted during
the Closing movement the control unit reverses the movement direction.
AUTOMATIC CLOSING:
The control unit can be set up to close the barrier automatically without
sending any additional commands.
Selection of this type of operation is described in Pause time programming
mode.
EMERGENCY STOP INPUT:
The control unit allows the connection of an emergency stop pushbutton
(NC). Pressing this pushbutton irrespective of the current operating mode
of the control unit will cause barrier movements to stop immediately. An
additional barrier movement command will be valid, provided the emergency
stop input is deactivated and, in any case, the control unit will perform the
barrier opening cycle after preflashing for 5 seconds.
Important: in Master/Slave applications, if you want to stop the Barriers
simultaneously, the Emergency Stop Inputs of the Master and Slave control

units must be interconnected.
PHOTOCELLS:
Photocells can be powered by and connected to the control unit in
accordance with directive EN 12453.
• Input DS1 (NC)
Tripping of the photocells during opening is disregarded, while during
closing it causes reversal of the direction of movement.
• Input DS2 (NC)
Tripping during opening causes momentary stopping of the barrier; once
the photocell is freed, the control unit resumes the opening movement.
Tripping during closing causes reversal of the direction of movement.
IMPORTANT: in Master/Slave applications tripping of input DS2 causes
exclusively reversal of the direction of movement in the closing stroke.
OPENING AND CLOSING LIMIT SWITCHES:
The control unit allows the connection of Opening and Closing limit
switches (NC). Tripping of the limit switches in the associated operating
cycles causes immediate stopping of barrier movement.
ADJUSTMENT OF MOTOR SPEED DURING THE "NORMAL" CYCLE:
The electronic control unit is equipped with a "SPEED" trimmer for
adjustment of Motor Force during the Normal cycle.
ADJUSTMENT OF MOTOR SPEED DURING THE "SLOWDOWN"
CYCLE:
The electronic control unit is equipped with a "SLOWING" trimmer
adjustment of Motor Force during the Slowdown cycle.
OBSTACLE DETECTION:
The electronic control unit is equipped with a "SENS" trimmer, completely
managed by the microprocessor, for adjustment of the opposing Force
required to detect the presence of an obstacle. The max. sensitivity
regulation in clockwise direction can be obtained with a trip time ranging
from 0.1 seconds to 7 seconds. Detection of an obstacle is indicated
visually by quick flashing of all the main menu LEDs.
IMPORTANT: The detection of an obstacle during the closing cycle inverts
the operator movement and during the opening cycle it stops all motion.
MOTOR ENCODER:
The default control unit has one encoder connected. The use of Encoders
facilitates the work of the control unit in the Obstacles Detection function
and ensures enhanced precision during execution of arm movements.
FLASHING LIGHT:
The control unit features an output to control a 24 V
light. Operation of the flashing light depends on the movement of the motor
and automatic closing, which, if selected, enables the flashing light also
during the pause time.
WARNING LIGHT / TRAFFIC LIGHT
The control unit allows a 24 V indicator light to be connected to display
the status of the automation system.
Indicator light off: barrier moving/closed - Indicator light on: barrier open
Using the dedicated TRAFFIC LIGHT ADAPTER, the traffic light output
can be used to control the operation of an access signal (traffic light), for
example a Red/Green traffic light.
OPERATION WITH TIMER:
The control unit allows a timer to be connected in place of the open – close
pushbutton. E.g.: at 08.00 am the timer closes the contact and the control
unit commands an opening movement; at 06.00 pm the timer opens the
contact and the control unit commands a closing movement. From 08.00
am – 06.00 pm at the end of the opening cycle the control unit disables the
flashing light, automatic closing and the remotes.
BUFFER BATTERY:
The control unit is equipped with a built-in 27.4 V
keep a full charge on the two 12V batteries connected in series. The
batteries allow the barrier to perform several complete open/close cycles
in emergency mode. The Flashing Light and LED strip output will operate
only for the first 4 seconds of the movement when mains power is absent.
CONTROL OF MOTOR ROTATION DIRECTION
Important Note: make sure the settings of dip-switch SW1 are
changed with the control unit off and then repeat the control unit
programming procedure.
