N° 7 - 8 DOOR DELAY (MEC 2000)
The length of delay time is always in proportion to the pulses detected by the encoder in the memorization
manoeuvre. There are 4 different combinations to choose from. N.B. If dip-switch 1B is positioned on 1
MOTOR, and for the MEC 1000 version, this function is excluded.

N° 9 - 10 ELECTRONIC FRICTION
MEC 1000 and MEC 2000 type panels are fitted with circuits that can control the gate's actual speed or
independently control two wings of the same gate. The motor becomes highly sensitive to any reductions
in speed that could be caused by an obstacle or the mechanical end limit device.
This sensitivity can be adjusted on the four levels by means of dip switches 9 and 10.
Installers should choose a medium power level.

N° 1 ON 2 motors are enabled.
OFF just 1 motor is enabled.
NB: 1 motor activates the relays of both motors in parallel but only reads from the M1 motor
For use with up-and-over doors
When dip 7A is OFF, the reversal stroke is enabled to prevent the motor from locking.
ON enables the courtesy light.
N°2
OFF enables the electric lock.
As regards large folding industrial doors, dip 2B must be ON while the position of dip A is
irrelevant.
ON the pre-flashing function is enabled.
N°3
OFF function disabled.
ON all memorising functions are enabled.
N°4
OFF correct position when the memorising procedure has terminated.
After memorising, make the automatic system carry out a complete manoeuvre (open/close) without activating
any devices.
MEMORIZING WORK TIME AND PAUSE
Lightly open the gate.
NB: for the barrier, position the bar at 45° from the horizontal ground line.
1- Place the Dip-switch 4B on the MEMORIZING ENABLED position = ON position (fig. 12). The flashing light
turns on.
2- Press the OPEN/CLOSE* push button (fig. 13) and check on the gates that the first manoeuvre is a closing
one (for this reason it is recommended to start with the gates slightly open); if this is not the case, reverse
motor polarities.
