QDA1
Differential
Pressure D
Over A
There is a leak on the
second component side.
Check the system for
internal and external
leaks on all manifolds
and plumbing for the
second component.
QDB1
Differential
Pressure D
Over B
QDC1
Alarm
Differential
Pressure D
Over C
Differential pressure
is low between driving
component and second
component. This alarm
is active only during Mix
mode.
The second component
side pump is cavitating.
Check paint supply on
the second component
side, increase paint
supply pressure.
QAD2
Differential
Pressure A
Over D
There is a leak on the
driving component side.
Check the system for
internal and external
leaks on all manifolds
and plumbing for the
driving component.
QBD2
Differential
Pressure B
Over D
QCD2
Alarm
Differential
Pressure C
Over D
Differential pressure is
high between driving
component and second
component. This alarm
is active only during Mix
mode.
The driving component
side pump is cavitating.
Check paint supply on
the driving component
side, increase paint
supply pressure.
