On the electronic board there is a trimmer that allows you to set the duration of the shutdown delay
(Factory setting on 3 minutes.) By acting on this trimmer it is possible to modify the delay time, up to 20
About a minute (Fig.20a).
LL MOTION
Factory settings
- appliance type (dip switch: mod.100 or 120: fig.18);
- switch-off delay (trimmer): full scale anticlockwise: 3 minutes (fig.19)
- 1 speed: position A of the jumper (fig.20).
Possible settings
- This model has 2 dip-switches. The position of switch 1 identifies the type of appliance (100 or 120: fig. 18) and MUST
keep the setting provided by the manufacturer. The setting of switch 2 has no effect whatsoever on the operation of the
appliance.
- Trimmer setting (fig.19). There is a trimmer on the PCB that enables adjusting the duration of the switch-off delay (from
3 to 20 minutes: clockwise = increase the delay, anticlockwise = decrease the delay).
- Jumper setting (fig.20). The motor has one operating speed: V. By appropriately setting the jumper as described in the
following table B it is possible to determine which of the two speeds Vmin and Vmax will be the actual operating speed
of the appliance.
NB: when the supply voltage is applied the appliance starts up in "Test Mode" for a time of approximately 1 min 30 sec.
In the first 30 seconds of operation in "Test Mode" the signal supplied by the MOTION module is ignored and the motor
runs at the speed set with the jumper. In the remaining 60 seconds the motor will only start after a signal from the
MOTION module, at the speed set with the jumper; when there is no signal from the MOTION module, the motor will stop
immediately (time lag for switching off = 0). At the end of the "Test Mode" phase, the appliance will go into normal
operation.

Wiring diagrams

When using the wiring diagram in Figure 22 b, the humidity control cannot be disabled (models 100-120 LL T HR); you
need to set the "Timer" operating mode (switch 6 = OFF in "DIP-switch" Table).
