ADJUSTMENT OF SENSITIVITY
EN 12445 requires that every automation system must pass impact tests measured with a special instrument.
Carry out the impact tests and change the encoder sensitivity through the trimmer SENS (part 10 fig. 1).
If adjustments are insufficient to make values fall within the graph indicated by the above standard, we
recommend installing a soft rubber profile on the leading edge of the gate in order to soften impact.
If the requirements of the standard can still not be met after having adjusted the sensitivity and mounted the
rubber profile, alternative devices must be mounted, such as a safety edge on the leading edge of the gate.
ELECTRONIC CLUTCH FUNCTION
This is an extremely important safety device. Calibration remains constant in time and is not subject to wear as
are mechanical clutches.
A. It is activated both during closing and during opening. When it cuts in, it inverts the direction without disabling
automatic closing if this has been enabled.
B. If it intervenes twice in a row, it automatically reverts to STOP mode, disabling automatic closing if this was
enabled. Intervening twice in a row means that the obstacle is permanent and any further movement could be
dangerous, forcing the user to give the close or open command.
C. If it intervenes three times in a row and for more than 120 seconds, the control unit runs an Emergency
procedure which slowly opens the gate all the way until it is flush with the end stroke and then closes it again
automatically if automatic closing mode has been enabled. In this way, if the end strokes have been lost, they
would be automatically resynchronized.
BLINKER FUNCTION
BRAIN LAMP Function: Besides being a safety device, the blinker gives both the end user and the installer
information on the gate operating status. Let's take a look at its function:
A. Pre-blinking is 0.5 second in opening mode and 1 second inclosing mode. For safety purposes this warns the
user that the gate will start moving shortly.
B. When gate automatic opening and closing are enabled (Dip 2 set to ON), the blinker remains on steady for 2
seconds indicating that the gate will be closed automatically.
C. When the gate is open, if a safety device cuts in, it flashes for 5 seconds and then goes off until the contact of
the safety device is reset.
D. It indicates the Programming phases described in the paragraph on Programming work times.
FINAL TEST AND INSPECTION
Always carry out a final test and inspection after having completed all the programming.
- Check correct operation of the protective devices (anti-crushing system, stop pushbutton, photocells,
safety edges, etc.).
- Check correct operation of the warning devices (flashing lights, open gate warning light, etc.).
- Check correct operation of the control devices (P/P button, remote controls, etc.).
