FUNCTIONAL CHARACTERISTICS

AUTOMATIC OPERATION:
When either the remote or the low voltage pushbutton panel is used to
control the gate, operation is as follows:
the first command opens the gate until motor time elapses or until the gate
reaches its opening limit position; the second command closes the gate; if
another command is transmitted before motor time has elapsed or before
one of the two limiters has been reached, the control unit reverses the
movement direction during both opening and closing.
STEP-BY-STEP OPERATION:
When either the remote or the low voltage control pushbuttons are used to
control the gate, operation is as follows:
the first command opens the gate until motor time or until the gate reaches
its opening limit position; the second command closes the gate; if another
command is transmitted before motor time has elapsed or before one of the
limit stops has been reached, the control unit stops the movement. Another
command causes the gate to start moving again in the opposite direction.
Step-by-step 1 operations:
When either the remote or the low voltage control pushbuttons are used to
control the gate, operation is as follows:
the first command opens the gate until motor time or until the gate reaches
its opening limit position; the second command closes the gate; if another
command is transmitted before motor time has elapsed or before one of the
limit stops has been reached, the control unit stops the movement during
both opening and closing. Another command causes the gate to start
moving again in the opposite direction.
AUTOMATIC CLOSING:
The control unit can be set up to close the gate automatically without sending
any additional commands.
The selection of this type of operation is described in Pause time programming
mode (PAUSE TIME).

PHOTOCELLS:
Photocells can be powered by and connected to the control unit in
accordance with directive EN 12453.
• SAFE1 input (NC)
Tripping of the photocells during opening is disregarded, while during
closing it causes reversal of the direction of movement.
• SAFE2 input (NC)
Tripping during opening causes momentary stopping of the gate; once
the safety is freed the control unit resumes the opening movement.
Tripping during closing causes reversal of the direction of movement.
To allow operation in compliance with EN 13849-1 Category 2 a photocell test
is performed before each movement. The control unit enables the movement
only if the test is passed; if it is not, the control unit inhibits all movements and
an alarm condition is signalled by blinking of all the programming LEDs on
transmission of any command.
5W).
OBSTACLE DETECTION (SENS):
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 adjustment can be
made with a trip time from a minimum of 0.1 seconds to a maximum of 7
seconds. Detection of an obstacle will always result in movement reversal
during closing (except in the final 5 seconds of the movement, when it will
cause a Stop) and reversal for 2 seconds during opening (except in the final
5 seconds of the movement, when it will cause a Stop).
Obstacle detection system also works with automations without
encoder.
OPERATOR SPEED ADJUSTMENT (SPEED):
The electronic control unit is equipped with a "SPEED" trimmer for operator
speed adjustment, completely managed by the microprocessor. Adjustment
can be performed in a range of between 50% and 100% of maximum speed.
Initial starting torque can be set for each movement by feeding the operator at
full power for 2 seconds, even if operator force control is enabled. Note: initial
starting torque is disabled automatically if the Soft Start function is enabled.
IMPORTANT: If the "SPEED" trimmer is adjusted the self-learning procedure
must be repeated because the movement and deceleration times may
change.
DECELERATION:
The operators deceleration function is used on gates to prevent the moving
leaves from slamming at speed into the limit stops at the end of the opening
and closing strokes.
During Motor Time programming (see Main menu), the control unit also allows
programming of deceleration in the desired points (immediately before full
opening and full closing); in addition, using the "DELAY" trimmer the force
intensity can be adjusted during the deceleration phase.
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.
ELECTRIC LOCK CONTROL OUTPUT:
The control unit features a voltage-free output contact to power an electric
lock. The contact is closed at each initial opening movement for a period of
2 seconds.
BACK-UP BATTERY:
The control unit has an integral 13.7 Vdc battery charger (so also for 24V
Operators a 12V battery must be fitted). The control unit allows connection
of a back-up battery with maximum capacity of 7Ah, which will allow the
execution of several complete opening and closing cycles at reduced speed
