DynaFlow TM User Manual - Maintenance
for a total of 32 seconds without faulting. As soon
as the controller senses flow from the master
CHANNEL, the timer is reset and will start once
again the next time a trigger signal is received
with no master CHANNEL flow.
Corrective Action:
In most cases, this fault is generated by the master
CHANNEL flow meter gears not turning (usually
stuck). Try flushing the system and watch the flow
rate or flow volume on the operator interface. If
there still is no flow, disassemble and clean the
flow meter. If this still does not correct the prob-
lem, see the section in this manual on FLOW
TOO LOW FAULTS. If this fault occurs while the
operator was not trying to spray, then the air flow
switch may be defective. This can be verified by
the GUN status on the operator interface.

INSTRUCTIONS
Control Panels
There is no maintenance schedule for control
panels other than good housekeeping practices.
These include.
• Keeping the door closed at all times. This
will maintain the dust-tight environment
required by the electronic printed circuit
boards.
• Plug all unused access holes into the cabinet
in order to keep contamination out.
• Use the following guidelines for cleaning
the Operator Interface:
Use cleaning solution specifically formu-
lated for computer monitors, a mild win-
dow cleaner, or isopropyl alcohol. DO
NOT use solvents. Most importantly,
use a clean, soft paper towel or tissue
and use very light force.
Fluid Control Components
It is recommended to record system settings such
as fluid supply and air supply pressures, etc.
Reference the appropriate service literature for
maintenance instructions.
