OPERATING FEATURES:
Step-by-step operation:
By using either the radio-control ( CODE led on ) or the low
voltage buttons to activate the gate, you obtain the following
action:
the first impulse activates the opening mechanism until the
motor time expires or the opening limit switch is reached, the
second impulse closes the gate. If an impulse is sent before
the motor time expires or one of the two end runs are reached,
the control unit will stop both opening and closing movements.
An additional control re-starts motion in the opposite direction.
Automatic closing :
The control unit closes the gate automatically without sending
additional commands.
The choice of this operating mode is described in the
instructions for setting the delay period.
Pedestrian Passage:
The control unit allows, using either the radio-control (P.
CODE led on) or the Pedestrian button, the Motor to run
for a programmable amount of time.
Blocking Device Input :
The control unit allows the blocking button connection (NC).
Tripping during any operating phase of the control unit causes
movement to stop immediately. An additional movement control
will be valid as long as you have disabled the blocking input,
and, in any case, the unit will carry out the opening stage
automatism with pre-flashing for 5 seconds. If the automation is
fully open, in this case, it will carry out the closing phase.
Attention: Jumper this input if not used.
Photocells:
The control unit allows Photocells to be powered and
connected in accordance with directive EN 12453.
- DS Input (NC)
Photocell operation is ignored during opening, whereas during
closing they will reverse the direction of movement.
To provide operation that meets EN 13849-1 Category 2, a test
is carried out on the photocells prior to every manoeuvre. The
control unit will only start the manoeuvre if the test is passed:
otherwise the control unit will not enable any movement, and
for every command all of the programming leds will flash,
signalling an alarm situation.
Opening and Closing Limit Switch:
The control unit allows the Opening and Closing Limit Switch
connection (NC). When it is triggered during the respective
operating phases, movement stops immediately.
Attention: Leave these inputs free if not used.
Motor Power and Speed adjustment:
The electronic control unit is equipped with a VR1 trimmer to
adjust motor Power and Speed, fully managed by the
microprocessor. The adjustment can be made within a range of
50% and 100% of the Maximum Power.
Nevertheless, every movement has an initial surge, powering
the motor for 2 seconds at the maximum power even if motor
power adjustment is enabled.
Attention: You will need to repeat the teach-in phase if you
wish to adjust the VR1 trimmer as operation and deceleration
times may be affected.
Obstacle detection:
The electronic control unit is equipped with a VR2 trimmer to
adjust the Counter Power required to detect the obstacle, fully
managed by the microprocessor.
The adjustment can be made by setting a time interval
between a minimum of 0.1 seconds and a maximum of 3
seconds.
Note: by setting the VR2 trimmer at the minimum, the
obstacle detection function is excluded.
Attention:
- When limit switches are connected to the control unit, the
detection of an obstacle always causes the motor to change
direction during the closing phase, and also during the
opening phase, for 2 seconds.
- When no limit switches are connected to the control unit, the
detection of an obstacle always causes the motor to change
direction during the closing phase (except for the last 5
seconds of the operation when it performs a Stop) and to
change direction for 2 seconds during the opening
phase(except for the last 5 seconds of the operation when it
performs a Stop).
Motor Encoder:
The control unit can have an Encoder integrated to the Motor.
Encoders can be used by the control unit for its Obstacle
Detection function to guarantee greater precision when
operations are being carried out.
Deceleration:
The motor deceleration function is used on the gates to stop
them from reaching their final position at a high speed in the
opening and closing phases.
The control unit allows deceleration to be programmed for the
desired points (before the gates are completely open or closed)
during Motor Timer programming (see Main menu).
If you are using the "Automatic programming" function (see
menu 2) it is also possible to include a deceleration phase (see
Main menu).
Operation with TIMER:
The control unit can have a timer set up instead of an openclose control button.
Example: at 08:00 the timer closes the contact and the control
unit opens the gate. At 18:00 the timer opens the contact and
the control unit closes the gate. During the interval between
08:00 and 18:00, at the end of the opening phase, the control
unit disables the flashing beacon, automatic closing and radio
controls.
Open Collector OUT 1-4 Output Operation:
The control unit has 4 open collector outputs to manage
auxiliary functions:
Out 1: Out 1 will be active in flash mode, only during the
Opening phase.
Out 2: Out 2 will be active in flash mode, only during the
Closing phase.
Out 3: Out 3 will be steadily active, only during the Pause
phase.
Out 4: Out 4 will be steadily active, only when the gate is
closed.
Integration of the RTX 2278 - RTX2252 safety system.
By installing module RTX 2278 on the control unit, it is
automatically possible to use, via radio, the functions of the
safety system composed of transceiver RTX 2278 (Base) and a
maximum of 2 RTX 2252 transceivers (Sensor 1 and Sensor 2).
For more details on system operation, see paragraphs “RTX
2278 Base” and “RTX 2252 Sensor”.
Before starting any operation, the control unit carries out a test
to make sure module RTX 2278 is working correctly; this fulfils
EN 13849-1 Category 2 operation.
Commands from Sensor 1 are ignored during opening,
whereas during closing they will reverse the direction of
movement.
Commands from Sensor 2 will stop movement in both closing
and opening phases.
PROGRAMMING :
The SEL key:this selects the type of function to be memorised,
which is indicated by a flashing Led.
Repeatedly press the key to select the desired function. The
selection will remain active for 10 seconds, indicated by a
flashing Led. If no other operations are carried out during this
time, the control board will return to its previous state.
The SET key: this programs the information according to the
type of function previously selected with the SEL button.
IMPORTANT: The SET key function can also be replaced by
the radio-control, if previously programmed (CODE led on).

3) INB. CMD. AP: (Command inhibition during opening and
pause time, if entered)
The command inhibition function during opening and pause
time, if entered, is used when automation includes a loop
detector. During the opening or pause phase the control unit
does not consider the commands sent by the loop detector with
every passage.
The factory settings of the control unit have disabled command
inhibition during opening and pause time. If it is necessary to
enable it, do the following: use the SEL key to move to the
flashing INB.CMD.AP LED then press the SET key. The
INB.CMD.AP LED will light up steady. Repeat the procedure if
you wish to restore the previous configuration.
4) LAMP/CORT. : (Selection of the flashing light or the
courtesy light)
The control unit has a 230 Vac output, for connection to a
flashing light or a courtesy light.
The control unit is supplied by the manufacturer with the
Flashing function enabled. If you wish to enable the flashing
beacon function, including during pauses, proceed as follows:
using the SEL key to move to the LAMP/CORT flashing LED
then press the SET key, and the LAMP/CORT flashing LED will
switch on steady.
Repeat the operation if you wish to restore the factory setting.
If you wish to enable the courtesy light, repeat the operation
described above, pressing the SEL button twice instead of
once (making the LAMP/CORT LED flash rapidly). Repeat the
operation if you wish to restore the factory setting.
5) PGM. AUT. : (Automatic Programming):
With this control unit it is possible to carry out Automatic
Programming ( SIMPLIFIED).
First, move the gates to their half-way position, press the SEL
button until the PGM. AUT. LED flashes and then press and
hold the SET button down. The control unit completes the Auto
programming phase by executing a complete opening and
closing phase (hold the SET key down until Auto Programming
is finished). At the same time, the Deceleration cycle is
automatically configured at 15% of the complete cycle.
During Automatic Programming, you can use the radio-control
key on the control unit instead of the SET key, only if previously
memorised.
6) T. MOT and DECELERATION:
time of max 4 minutes)
(Programming a motor operation
The control unit is factory supplied with a predefined motor
operating time of 30 sec. without deceleration.
If it is necessary to modify the motor operating time,
programming must be carried out when the gate is closed, as
follows: use the SEL key to move to the flashing T.MOT LED,
then press the SET key briefly. The Motor will begin its opening
cycle. When it starts the initial point of deceleration, press the
SET key again. At the same time, the motor will decelerate until
it reaches the required position. Press the SET key to finish the
opening cycle. The T. MOT LED will then start flashing quickly.
Now repeat motor time programming and the deceleration
operation for the closing cycle. If you do not want the control
unit to decelerate, when the opening and closing phase is
finished, press the SET key twice during programming, instead
of just once.
During programming it is possible to use the radio-control key
located on the control unit, instead of the SET key, only if
previously memorised.

follows: use the SEL key to move to the flashing T.MOT PED.
LED, then press the SET key briefly. The Motor will start the
Opening cycle; press the SET key again at the point where you
wish to start deceleration: the T. MOT. PED. LED will start
flashing at a slower rate and the Motor will decelerate; when it
reaches the required point, press the SET key to finish the
Opening cycle. At this point the T. MOT PED. LED will start
flashing at its standard pace again and the Motor will begin the
Closing phase; repeat the above operations for the Closing
phase.
If you do not want the control unit to decelerate, when the
opening and closing phase is finished, press the SET key twice
during programming, instead of just once.
During programming it is possible to use the radio-control key
located on the control unit, instead of the SET key, only if
