ACTIVATION BOARD
This board activates, through relays, the equipment
working and the DC motors directly. It manages the sig-
nals originating from the cams and/or microswitches on
the various equipment. Furthermore, it controls the boiler
management board. The board works with 24 Vac for the
electronic parts and the payment systems.
The board management software is loaded directly,
(through RS232) on the microprocessor.
- The green LED 3 flashes during the normal operation
of the board;
- The yellow LED 6 indicates the presence of 5 Vdc.
- The red LED 4 is on during the board reset
- The red LED 2 (not used on this model), indicates the
operating status of the instant drinks boiler resistance.
- The red LED 5 indicates the operating status of the
instant boiler resistance.
- The green LED 8 (not used on this model) indicates the
pulses of the volumetric counter.
- The green LED 5 indicates the presence of 34Vdc.
- The green LED 7 indicates the presence of regulated
34Vdc.
