IMPORTANT FOR the INSTALLER
−Before automating the gate, check that it is in good conditions, in compliance with the Machinery Directive and with EN 12604.
−Check that the location where the installation is located enables compliance with operating temperature limits specified for the device.
−The safety of the final installation and compliance with all prescribed Standards (EN 12453 - EN 12445) is the responsibility of the person who assembles the various parts to construct a total closing.
−Once installation is finished, it is recommended that all necessary checks be performed (appropriate programming of the control panel and correct installation of safety devices) to ensure that compliant installation has been performed.
−The control unit does not have any type of isolating device for the 230 Vac line. It is therefore the responsibility of the installer to set up an isolating device inside the system. It is necessary to install an omnipolar switch, surge category III. It must be positioned to provide protection from accidental closing, pursuant to point 5.2.9 of EN 12453.
−For the power supply cables, use flexible cables in an insulating sheath in harmonised polychloroprene (H05RN-F) with a minimum conductor section of 1mm2
−The various electrical components external to the control unit must be cabled in accordance with standard EN 60204-1 as amended, and as set forth in point 5.2.7 of EN 12453. Power cables may have a maximum
diameter of 14 mm. The fixing of power and connection cables must be secured through the use of "optional" cable glands supplied. Pay careful attention when fastening the cables so that they are anchored in a stable manner.
Furthermore, care is required when drilling holes in the outside casing where connecting and power supply cables will pass, and when assembling the cable glands, so that everything is installed so as to maintain the panel's IP protection characteristics.
−The assembly of a push button panel for manual control must be completed positioning the push button panel in such a way that the user is not placed in a dangerous position.
−The rear part of the casing is equipped with
fittings for wall mounting (it is possible to drill holes for installation with plugs, or there are already holes available for installation with screws). Plan and implement all necessary measures to achieve an installation that does not alter the IP protection.
−The gear motor used to move the gate must comply with the requirements of point 5.2.7 of EN 12453.
−The D.S. Power Supply output must be dedicated to the power supply of the photocells only. It cannot be used for other applications.
−With every operation cycle, the control unit performs the photocell operating test, ensuring protection against the rupture of Category 2 crush-proof devices, in accordance with point 5.1.1.6. of EN 12453. Accordingly, if the safety devices are not connected and/or are not working, the control unit is not enabled for operation.
−The safety function ensured by the control unit is active only during closing, therefore, protection on opening must be ensured in the installation phase with measures (guards or safety distances) independent of the control circuit.
−For proper functioning of the radio receiver, if using one or more control units, the installation at a minimum distance of at least 3 metres one from the other is recommended.

OPERATING CHARACTERISTICS:
Automatic Operation:
By using both the radio control ( CODE LED on ) and the low voltage push button panel ( PUL ) to activate the gate, the following functioning is obtained:
the first impulse commands the opening mechanism until motor time expires. The second impulse commands gate closing. If an impulse is sent before the motor time has expired, the control unit will reverse motion direction both for opening and closing.
Step-by-step operation:
By using both the radio control ( CODE LED on ) and the low voltage push button panel ( PUL ) to activate the gate, the following functioning is obtained:
the first impulse commands the opening mechanism until the motor time expires. The second impulse commands gate closing. If an impulse is sent before the
motor time has expired, the control unit will stop the motion during opening and closing phase. An additional control restarts motion in the opposite direction.
Automatic closing :
The control unit closes the gate automatically without sending additional commands.
Selecting this operating mode is described under the instructions for setting the pause time.
Pedestrian Passage:
The control unit allows only Motor 1 to be activated using either the radio control ( CODE PED. LED on) or the push button panel ( PED ), for the programmed time. ( T.MOT. PED. LED ).
Safety device 1 :
The control unit allows Photocells to be powered and connected in accordance with directive EN 12453.
If the device trips during opening, it is ignored. If it trips during closing, gate motion is reversed.
The control unit compulsorily requires the use of photocells, connected to dedicated inputs, otherwise the unit is not enabled for operation.
Safety device 2:
The control unit allows Photocells to be powered and connected in accordance with directive EN 12453.
If the device trips during opening, the gate stops momentarily. Once freed, the control unit continues the opening phase. If the device trips during closing, gate motion is reversed.
The control unit compulsorily requires the use of photocells, connected to dedicated inputs, otherwise the unit is not enabled for operation.
Adjusting Power and Initial Surge:
The electronic control unit is equipped with a "POWER " 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 Motor Time programming procedure if you wish to adjust the "POWER", as operation and deceleration times may be affected.
Obstacle detection:
The electronic control unit is equipped with a "SENSITIVITY" 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 "SENSITIVITY" trimmer at the minimum, the obstacle detection function is excluded.
Warning:
-During the slowed motion phase the obstacle detection function is always disabled.
-The obstacle detection function always causes motion reversal during the closing phase (except in the last 5 seconds of operation, in which case it stops) and reversal for 2 seconds during the opening phase (except in the last 5 seconds of operations, in which case it stops).
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). It is also possible to select the motor power to which the deceleration phase between 6 different levels of power is carried out (see Extended menu 3). The intermediate level is set during factory configuration.
