N° 7A-8A DOOR DELAY (MEC2000)
The duration of the delay is always proportional to the pulses read by the encoder during
the memorising operation.

N° 9A-10A ELECTRONIC TYPE CLUTCH
The MEC1000 / MEC2000 panel is fitted with an encoder that can control the effective
speed of the gate or the two gates independently in the case of swing gates.
The motor thereby becomes sensitive to any drops in speed that can be caused either by
an obstacle or the mechanical travel stop. This sensitivity can be adjusted to 4 levels with
dip-switches 9A and 10A. Fitters should opt for an average maximum power level.

N° 1B ON enables 2 motors.
OFF enables just one motor.
NB: 1 motor activates the relays of both motors in parallel but only reads from the M1 motor
encoder.
For use with 2-motor up-and-over doors.
When DIP 7A is OFF, the reversal stroke is enabled to prevent the motor from locking.
For use with sliding gates.
N° 2B ON enables the courtesy light.
OFF enables the electric lock.
Output 13/14.
N° 3B ON enables the pre-flashing function.
OFF disables the pre-flashing function.
N° 4B ON enables all the memorising functions.
OFF is the position at which it must stay when memorising operations have terminated (normal
opening and closing operation).
MEMORIZING WORK AND PAUSE TIME
Exit the automatic cycle and open the door a little.
NB: only for barriers, incline the bar to 45° from horizontal.
1- Move dip 4B to the memorising position, i.e., ON (fig. 11). The light will start flashing.
2- Give an impulse with the remote control unit or the open/close button (fig. 12). The gate should start
closing; if it opens, suspend programming by resetting the electrical panel (use the tip of a screwdriver to
short circuit the two metal reset pins for a second), and then switch off the panel and invert the motor.
3- About 2 seconds after closing (fig. 13), the gate opens automatically.
4- Wait for a certain amount of time T (as preferred) and then give an impulse to close the door.
T becomes the pause time before automatic closing (if programmed with dip 4A).
During all these phases the light keeps flashing.
5- Now that all the open/close phases have been memorised, move dip 4B to OFF (fig. 14).
6- During normal use, when the gate is closing it is supported, while in the opening phase it never reaches
the travel stop (ground supports).
After memorising has terminated, make the automatic system carry out a complete manoeuvre (open/close)
without activating any devices.
