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.
PEDESTRIAN OPENING:
By means of the remote (CODE P. LED lit) the remote control makes it
possible to drive the Operator for a programmable time, typically to allow
pedestrian access.
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 immediate stopping of the gate movement. An
additional gate movement command will be valid provided the emergency
stop input is deactivated and, in any case, the control unit will execute the
gate opening cycle with 5 seconds preflashing.
IMPORTANT: Jumper this input if it is not to be used.
PHOTOCELLS:
Photocells can be powered by and connected to the control unit in
accordance with directive EN 12453.
Tripping of the photocells during opening is disregarded, while during
closing it 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 each command.
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.
IMPORTANT:
• If limit switches are connected to the control unit detection of an obstacle
will always result in movement reversal during closing and reversal for 2
seconds during opening.
• If there are no limit switches connected to the control unit 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 Operator 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.
OPENING AND CLOSING LIMIT SWITCHES:
The control unit allows the connection of two Opening and Closing limit
switches (NC). Tripping of the limit switches in the associated operating
cycles causes immediate stopping of the gate movement.
IMPORTANT: Do not jumper these inputs if they are not used
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
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 in emergency mode. If fitted, a Flashing Light will operate only for the
first 4 seconds of the movement when mains power is absent.
PROGRAMMING:
SELECT key: selects the type of function to store; the selection is indicated
by blinking of the LED.
Press the key repeatedly to go to the desired function. The selection
remains active for 10 seconds shown by blinking of the LED; when this
interval elapses the control unit returns to the original state.
SET key: programs the information in accordance with the function type
preselected with the SEL key.
IMPORTANT: The SET key function can be replaced by the remote if
programmed beforehand (CODE LED lit).
Programming enabled only when safety devices are not active.
