ONDITION
The device makes it possible to activate controls based on the
light detected through the integrated sensor. Sensor sensitivity
can be modified using the VR1 trimmer present inside of the
device. By using the SEL and SET programming keys it is
possible to select different types of operation. In the default
configuration the device is set at an intermediate sensitivity to
light through the VR1 trimmer and Monostable functioning with
NO contact output.

ENSITIVITY TO THE CAPTURED LIGHT
The device makes it possible to adjust Sensitivity of the light
captured through the VR1 trimmer. The switching on of the
LIGHT LED on the device indicates that the intensity of cap-
tured light exceeds the selected intervention threshold; in this
way we will have a reference to the current light conditions to
establish the desired one.

LED
SEL Key
: selects the type of function to memorise, the choice
is indicated by the flashing of the LED. By repeatedly pressing
the key, it is possible to position oneself on the desired func-
tion. The selection remains active for 15 seconds, displayed by
the flashing LED, after which the control unit returns to the
original status.
SET Key
: carries out programming of the function chosen with
the SEL key.
Indicator LED
LED on: option memorised.
LED off: option not memorised.
Flashing LED: option selected.

3) I. CMD Relay Output NO Relay Output NC
1) MONO
(Monostable Operation / Impulse 1 sec.)
The control unit is supplied with the Monostable operational
mode enabled (MONO LED OFF), meaning that the relay will
activate every time that the sensor determines that there is no
light, and will deactivate in the presence of light. When needing
an Impulse type of functioning, meaning that the relay is only
activated for one second each time that the sensor determines
that there is no light, programming must be completed in the
following way: position the SEL key on the flashing of MONO
LED then press the SET key, the MONO LED will simultane-
ously switch on permanently and the programming is com-
pleted. Repeat the procedure to restore the previous configura-
tion.
2) TEMP.
(Timer Function enabled / disabled)
The control unit is supplied with the Timer functioning disabled
(TIMER LED OFF).
When the device needs to be used with the timed function,
meaning that the control relay is active for the programmed
amount of time after the sensor has been activated.
Proceed as follows: position the SEL key on TIMER LED and
press the SET key to start programming, at the same time the
TIMER LED will start to double flash; every double flash of the
TIMER LED corresponds to an increase of 30 minutes up to a
maximum of 12 hours (24 double flashes), press the SET key
until the desired time is reached; at the same time the selected
value is saved and the TIMER LED will stay on.
It is possible to repeat the operation in case of an incorrect
programming.
Displaying the programmed Time
When verifying the previously programmed Time, it is possible
to display it in the following way: with the SEL key position
yourself on TIMER LED, the LED will start to double flash for
the number of times equal to the Time programmed in the
memory (every double flash of the TIMER LED corresponds an
increase of 30 minutes), (
example: 4 TIMER LED flashes =
120 minutes).
3) I. CMD
( Inversion of NO / NC control functioning )
The control unit is with a Normally Open output operational
mode (LED I. CMD OFF).
When needing an inverted mode of operation, with the control
output set at Normally Closed, proceed as follows: position the
SEL key on the flashing of LED I. CMD then press the SET
key, the LED I. CMD will simultaneously switch on perma-
nently and the programming is completed. Repeat the proce-
dure to restore the previous configuration.
