Comunello Automation CU - 24V - HP Instructions D'utilisation Et D'installation page 37

- Slow blinking: opening movement;
- Rapid blinking: closing movement.
7.2.12 OPERATION WITH TIMER:
The control unit allows a timer to be connected in place of the open – close
push-button.
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.
7.2.13 ELECTRIC LOCK CONTROL OUTPUT:
The control unit features an output to control a 24V DC 15W max. electric lock.
The command is switched on at each initial opening movement for a period of
2 seconds.
7.2.14 BUFFER BATTERY:
The control unit is equipped with a built-in 24 V maintenance battery charger.
The control unit allows the connection of a buffer battery of 7Ah recommended
capacity, which will allow a number of emergency manoeuvres at reduced
speed. The flashing light, if present, in the absence of mains voltage, will
work only for the first 4 seconds of the manoeuvre.
7.3 DIP-SWITCHES AND TRIMMERS ADJUSMENTS
Important Note: change the settings of dip-switches SW1 and SW2
with the control unit off and only subsequently repeat the control unit
programming procedure.

MOTOR CONSID. MOTORS
The electronic control unit is equipped with a dip-switch SW1 that is
used to select operation with 1 or 2 motors and to define which of the
two starts first and which starts second.
7.3.2 MOTOR 1 AND MOTOR 2 STROKE DIRECTION
SW2 SW2

The electronic control unit is equipped with dip-switches that can be used to
change the stroke direction of each connected motor without rewiring the electrical
connections: dip-switch 1 controls Motor 1 while dip-switch 2 controls Motor 2.
7.3.3. DECELERATION (SLOWING):
The motors 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 the control unit allows programming of

deceleration in the required points (immediately before full opening and full
closing); in addition, using the "SLOWING" trimmer the force intensity can be
adjusted during the deceleration phase in three fine adjustment level settings.
7.3.4. MOTOR SPEED ADJUSTMENT (SPEED):
The electronic control unit is equipped with a "SPEED" trimmer for adjustment of
the speed delivered by the Motors, completely managed by the microprocessor.
Adjustment can be performed in a range 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 speed control is enabled.
Important notes:
- Initial starting torque is disabled automatically if the Soft Start function is
enabled;
- If the "FORCE" trimmer is adjusted, the self-learning procedure must be
repeated because the movement and deceleration times may change.
7.3.5. 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 notes:
-the detection of the obstacle causes the brief reversal of the motion during
closing and opening.
- In the absence of limit switches connected to the control unit the detection
of the obstacle always causes the brief inversion of the motion except in the
last 5 sec. of the stroke in which it makes a stop.
- In the absence of encoders and electronic limit switches, the detection
of the obstacle takes place by current measurement. To guarantee this
functionality it is necessary to adjust the slow-down trimmers as follows:"
Minimum recommended settings for obstacle / limit switch
MODEL
SLOWING 80% 30% 80% 30%
SPEED 50% 20% 50% 20%
In the absence of encoder and limit switch, in the last 5 seconds of the motor time,
the stop of the leaves is interpreted as the limit switch.
7.3.6 BLACK-OUT
In case of power failure and subsequent reactivation of the mains voltage, the
first maneuver will be opened with a fixed and reduced speed compared to the
trimmer SPEED ; when the presence of a mechanical blockage is encountered,
in the absence of an electric limit switch, the leaves do not go into obstacles, but
execute a STOP. While sending a later input, the leaves always close at a reduced
speed until they are completely closed. The following movement will be done with
the speeds defined by the trimmers.
8 DETAILED DESCRIPTION
PROGRAMMING
PROGRAMMING:
SELECT key: it determines the type of function to be memorized, as indicated
by the blinking of the LED.
By pressing the key several times, it is possible to scroll the menu and move to
the desired function. The selection remains active for 10 seconds, displayed by
the flashing LED; when this interval elapses, the control unit exits programming.
SET key: it confirms and changes the programming according to the type of
function determined by the SELECT key.
Following confirmation, the respective LED remains on / off for about 2 sec. and
then starts flashing again.
Important notes:
- the function of the SET key can also be replaced by the remote control if
previously programmed (LED L2 CODE TX lit).
- Programming enabled only with the closure of N.C contacts enabled.
