Before performing any troubleshooting
procedures:
1. Relieve pressure.
See
Pressure Relief Procedure, page 49
2. Turn the main power switch OFF.
3. Allow equipment to cool.
Try the recommended solutions in the order
given for each problem, to avoid unnecessary
repairs.

The k-factor entered in the
ADM is incorrect.
Update the k-factor. See
Increase the feed pump
pressure.
Install a larger feed pump.
Clean the y-strainer filter.
Install a smaller mix chamber
in the spray gun.
Cavitation is reducing the
pump performance.
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.
Place the heated hose on flat
ground. Spray material into a
waste container until all air has
left the 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.
The material flow and ratio are
not displayed on the ADM.
The flow meter is disabled.
Enable the flow meter on
System Screen 1.
The flow meter repeatedly
disables itself.
The inlet sensors are disabled.
Enable the inlet sensors. Inlet
sensors must be enabled for
the flow meter to function.
