OPERATING MODE
- There are 6 distinct operating modes read at startup.
Settings must be made by dip-switches (micro-switches) before
switching on:
1) ON / OFF (no dimming) (factory settings) ;
2) PUSH dimming (OFF regulation, 2-100%) - three profiles: slow,
fast, up/down;
3) DALI (OFF regulation, 2-100%)
-Power on: 100%,
-System fail level: 100%;
4) 1-10V dimming , brightness reduction down to a minimum
without ever switching off;
5) 0-10V dimming , brightness reduction until complete shutdown;
6) SLAVE.
The 1-10V / 0-10V and PUSH operating modes are in alternative
between them.
- Dimming time (min-max; max-min): slow profile: 8 seconds;
fast profile: 5 seconds; up/down profile: 8 seconds.
- Low level in Push is different from 0 to distinguish it from OFF.
Restarting after power failure:
-If in 1-10V / 0-10V dimming mode, the input value is read according
to the programming;
-If in PUSH dimmer mode, it starts from the last data set;
-If in DALI dimmer mode, it starts from the last data set.

PUSH MODE (Setting via DIP-SWITCH)
- Short press the key for ON / OFF (ramps on and off
shutdown).
- Long press of the key for dimmer.
- Storage of the last dimming data. At each ON the driver starts
from the last data set.
- Alignment procedure (necessary to compensate for errors of
synchronization when there are many drivers in parallel): from
position OFF / ON keep the key pressed for a long time (30sec) the
drivers will be 100%; the next time the key is pressed, the luminous
flux will start to decrease according to the set profile.
- Maximum recommended cable length PUSH: 15 meters.
- Maximum number of recommended power supplies: 10.
SLOW PROFILE (SLOW) (Setting via DIP-SWITCH)
- With each pressure, the dimming continues up to the maximum level
(or minimum), after about 1sec, is reversed.
Time from minimum to maximum: 8 seconds.
FAST PROFILE (FAST) (Setting via DIP-SWITCH)
- With each pressure, the dimming continues up to the maximum level
(or minimum), after about 1sec, is reversed.
Time from minimum to maximum: 5 seconds.
UP / DOWN PROFILE (UP / DOWN) (Setting via DIP-SWITCH)
- With every pressure the dimming reverses the sense. Arrived at the
level minimum (or maximum), the state is maintained.
Time from minimum to maximum: 8 seconds.
MODALITY 1-10 V (passive / active)
- Potentiometers up to 100 Kohm can be used. The brightness
of the LEDs varies proportionally to the signal sent to the terminal
from 2 to 100%.
- The brightness of the LEDs changes proportionally or
logarithmic depending on the model of potentiometer used
(recommended logarithmic).
- Set dip-switch 5 to ON position (1-10V for passive resistor)
for resistive potentiometers: (Iout max 1,4mA).
- Set dip-switch 5 to the OFF position (1-10V for active systems)
for active systems (Konnex interfaces, EIB, touch screen
potentiometers, PC, home automation systems, etc.):
(Input impedance 100 Kohm).
MODALITY 0 - 10V (passive / active)
- 0-10V systems can be used. The brightness of the LEDs varies from
0 to 100% proportionally to the signal sent to the terminal.
- Set dip-switch 5 to ON position (0-10V for passive resistor)
for passive systems; you still have the possibility to switch off
completely also using resistive potentiometers: (Iout max 1,4mA).
- Set dip-switch 5 to the OFF position (0-10V for active
systems) for all active systems (Konnex interfaces, EIB, touch
screen potentiometers, PC, etc.): (input impedance 100Kohm).
SLAVE MODE
- The SLAVE function can only be used in the presence of power
supplies with MASTER function (eg LE42DP).
Note: In the case of incorrect setting of the Dip-Switches, when
switched on, the Driver starts and flashes LEDs with frequency
1sec ON and 1sec OFF.
