ACTIVATION BOARD
The board is powered at 24 V and controls
the activation of various users and sensor
signals.
The LED indicators signal the following:
- DL1 (38) reset LED
- DL2 (19) run LED flashes during normal
operation
- DL3 (15) yellow power LED indicates pres-
ence of +5 VDC
- DL4 (17) yellow LED - flow meter impulses
- DL5 (15) not used
- DL6 (21) red LED indicates that the
espresso heating element is working
- DL7 (20) red LED indicates that the steam
heating element is working (if present)
relay
function
RL1: Grinder
RL2: Coffee release electromagnet
RL3: Grinder 2*
RL4: Coffee release electromagnet 2*
RL5: Water pump
RL6: Motor mixer
RL7: 230 V safety relay
RL9: 24 V safety relay
RL11: Grinder reverse rotation relay
* models with double coffee beans
The RL7 safety relay interrupts the pro-
tector conductor (230 V) when the door is
opened.
The RL9 safety relay interrupts the 24V
when the door is opened.
model
identification
The J20 connector (with jumpers) allows to
identify the model of the equipment.
