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.
