Flow Meter
Before perfo
rming any troubleshooting procedures:
1. Relieve Pressure. See Pressure Relief Procedure, page 49.
2. Turn main power switch OFF.
3. Allow equipment to cool.
Problems
Try the rec
ommended solutions in the order given for each problem, to avoid unnecessary repairs.
Problem
Cause Solution
The k-factor entered in the ADM is
incorrect.
Update the k-factor. See
Replace Flow Meter, page 64.
Increase
the feed pump pressure.
Install
a larger feed pump.
Clean th
e y-strainer filter.
Install a smaller mix chamber in
the spray gun.
Cavitat
ion is reducing the pump
perform
ance.
Condition the material in the drums
to the ambient temperature of the
proportioner.
Re-route the feed hoses to a lower
height.
Purge air from the system. Refer
to your ratio monitor manual for
instructions.
The material ratio is significantly
offset from 1 : 1.
Air is trapped in the system,
between the feed pumps and the
heated hose.
Pla
ce the heated hose on flat
gro
und. Spray material into a
was
te container until all air has left
th
e system.
Increase the feed pump pressure.
Install a larger feed pump.
The ADM displays low inlet
pressure alarms, but the inlet
pressure reading appears correct..
While spraying, the inlet pressure
drops below 30 psi.
Install a smaller mix chamber in
the spray gun.
T
he material flow and ratio are not
displayed on the ADM.
T
he flow meter is disabled.
E
nable the flow meter on System
Screen 1.
The flow meter repeatedly disables
itself.
The inlet sensors are disabled. Enable the inlet sensors. Inlet
