Normal Start-Up Procedure
Before attempting start-up:
• Inspect the entire system and make sure
that all air and fluid hoses are in place and
secure, and that all other system compo-
nents are in good condition.
• Review and perform any required preven-
tive maintenance procedures.
• Inform personnel in the immediate area
that the system is being started.
• Observe the operation of the system as it
is started and be ready to shut it down in
the event of a problem.
The following procedure assumes that the system
was running normally when previously operating.
This is only a recommended procedure. Variance
from this procedure is dependent on the installa-
tion, operation and protocols.
1. Turn on the main power disconnect to the
fluid control panel.
2. Turn ON the panel power switch.
3. Verify that the Operator Interface is operating
normally and that there are no errors.
4. Turn ON the factory air supply to the E/P
transducers and any other pneumatic control
circuits.
5. Supply fluid pressure to the system.
6. Turn ON any auxiliary equipment that may
be interlocked with the fluid flow controller such
as the booth exhaust.
7. Perform a system flush of each GUN.
8. LOAD the material to be sprayed. This may
be controlled automatically or manually depend-
ing on the system.
9. A "dummy" JOB can be run to verify the op-
eration of the entire coating system before
spraying production parts. In general, the longer
a system is shutdown, the more importance
should be placed on the start-up procedure.
Normal Shutdown Procedure
The shutdown procedure should be basically op-
posite of the start-up procedure. The degree or
level to which the system is shutdown depends on
how long the shutdown is to last. The following are
considerations when shutting down the system.
1. Place the system in a safe mode when per-
sonnel will not be present for extended periods
of time.
2. It is recommended to keep fluid loaded in the
flow meters to prevent the gears from sticking
during start-up. Generally this is the flushing
solvent.
• Verify that the local Operator Interface is
working properly and that no errors are be-
ing reported. Refer to the "Operator Inter-
face" manual for additional information.
• Turn ON the system host controller (PLC
or PC) and verify proper operation. Con-
figure the flow controller. This is usually
performed at the local Operator Interface
panel, but can be through the system con-
troller depending on the installation. Refer
to the "Operator Interface" manual for addi-
tional information.
• Turn ON the factory air supply to the E/P
transducer(s) and adjust the regulator to
90 psi minimum, 110 psi maximum.
• Turn ON the fluid supply pressure to the
material regulator or color change valves.
• Inspect the air and fluid system for any
leaks and fix before continuing. Fluid should
NOT be flowing through the system at this
point.
• Perform a system flush, one GUN at a
time.
• Load paint.
• Perform a calibration check of each CHAN-
NEL.
• Verify operation of any safety or system
interlocks.
• Perform and verify remaining system oper-
ation. This includes any automatic opera-
tions such as a color change sequence.
• Observe the fluid flow response of each
GUN. Refer to "Operator Interface" manual
and related sections of this manual.
