HCM
Pressure Sensor
Error Inlet B
Bad sensor.
Check if the error follows
the inlet sensor. Disconnect
inlet sensor cables from
the HCM (connectors 8
and 9). Reverse A and B
connections and check if
the errors follows. If the
error follows the sensor,
replace the inlet sensor.
Pressure
difference between
Aand B material
is greater than the
defined value.
Ensure material flow is
equally restricted on both
material lines.
Pressure
imbalance is
defined too low.
Ensure that the pressure
imbalance value, on the
System Setup screen, is at
an acceptable maximum
pressure to prevent
unnecessary alarms and
abort dispenses.
Out of material.
