DESCRIPTION OF OPERATION
OPERATION
- Single leaf logic: only the output indicated with M1 is activated
- Two-leaf logic: both outputs M1 and M2 are activated (M2 leaf
delayed on opening)

- High deceleration speed
- Low deceleration speed
- Final closure stroke active: at the end of the closing cycle, full
power is applied for 2s to the motors to improve electric lock
closure.
- Final closure stroke not active.
FINAL CLOSURE
STROKE
- Release stroke activated: the electric lock is activated during a
brief phase of closure against the stops, and is deactivated shortly
after start-up of M1.
- Release stroke deactivated: the electric lock is activated shortly
before start-up of M1, and is deactivated shortly after start-up of
M1

WARNING: Microswitches must only be adjusted when the control unit is disconnected from the
power supply; any new microswitch settings are applied on subsequent start-up.
After making new settings on microswitches, we recommend repeating the work time programming
procedure (see control unit programming).
!
WARNING:
During deceleration, the force is reduced and therefore the speed depends on the characteristics
of the motor and gate. AN EXCESSIVELY LOW DECELERATION SPEED COULD PREVENT
SMOOTH LEAF MOVEMENT IF NECESSARY, DISABLE BY MEANS OF DIP2 OF SW2.

DECELERATION
SETTINGS
- Deceleration deactivated.
- Deceleration activated.
- Start-up torque activated: on start-up motors are powered up at
the maximum voltage for 2s.
RECOMMENDED ABOVE ALL IN WINTER
- Start-up torque deactivated: on start-up motors are powered up at
the voltage set by means of the potentiometer.
WARNING: in this case there may be difficulties with start-
up above all if a low force level is set

ATTENTION: The motors MT/30/2 and MT/38/1 arriving against the stop block while slowing
down are subjected to vibrations – not damaging – but that might cause some noise.
In order to avoid the noise:
deactivate the slowing down function – dip2 SW2 in ON-, in this case the leaf arrives against
the stop block at normal speed
!
