EVOCA La Radiosa - Activation Board

05-2019 0073 00 77
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: it flashes during normal
operation;
-DL3 (15) yellow
powEr LED: indicates the
presence of +5 V DC;
-DL4 (17) yellow LED - flow meter impuls-
es;
-DL5 (15) not used;
-DL6 (21) red LED indicates that the coffee
heating unit heating element is working;
-DL7 (20) not used.

RL1: Grinder
RL2: Coee-releasing electromagnet
RL3: Grinder 2*
RL4: Coee-releasing electromagnet 2*
RL5: not used
RL6: Motor mixer
RL7: 230 V safety relay
RL9: 24 V safety relay
RL11: Grinder reverse rotation relay
* models with double coee beans
The RL7 safety relay interrupts the neutral
(230 V) when the door is opened.
The RL9 safety relay interrupts the 24V
when the door is opened.
