Hydaulic Circuit
This page allow to test the functionality of hydraulic circuit:
Info:
mA: indicates the maximum current (in mA) absorbed by the brew unit in motion. The value must
not exceed 300 mA
Encoder Pulses Home-Work: indicate the number of encoder pulses from Home to Work posi-
tion or vice versa. Move the brew unit from Home to work or vice versa and the measured value
must bein the range [2000 – 2100].
H/W: Becomes active when the Brew Unit reach HOME or WORK position
Pres: Becomes active if the Brew Unit is present in machine
DDr: Becomes active if the Dreg Drawer is present in machine
Door: Becomes active if the Frontal Door is closed

Boiler: when pressed activate/deactivate the boiler if the temperature is less than 90°C
Pump: when pressed activate/deactivate the pump
Ev S: when pressed activate/deactivate the Steam/Water electrovalve (24V Dc)
Ev D: when pressed activate/deactivate the discharge electrovalve (24V Dc)
Info:
p/s: indicate the current number of water fl ow expressed in pulses/sec. When is activated the
pump and one electrovalve the value measured must be equal to or greater than 10 p/s.
