The machine operating data can be checked by means of luminous
warning lights called LEDs. 3 LEDs are installed on a small
electronic board called “LED board”, and are characterized by
different colours:
red, yellow and green.
A red LED is also present on the card.
The only unit equipped with a LED board is the Cassette
42GW----K (inside the grille). The other machines can be externally
fit with this board.
The operation of the LEDs on the board is the following:
• in the event of alarm (diagnostic message active) the red LED
starts flashing and the LED installed on the card flashes with the
same frequency.
• When the anti-freeze protection is active, the red LED remains
constantly ON.
• If the window contact is active, the red LED on the board remains
ON.
• If a communication problem occurs, the red LED remains ON.
• When operating in Occupied mode, the green LED on the LED
board remains constantly ON.
• When operating in Unoccupied mode, the yellow LED on the LED
board remains ON.
• When the unit is disabled by a control on the CCN communication
bus, all LEDs on the LED board remain OFF.
