Grounding
Check Resistance
Have a qualified electrician check resistance between
each ProControl component and true earth ground. If
resistance is greater than 1 ohm, a different ground site
may be required. Do not operate the system until the
problem is corrected.
Pressure Relief
Procedure
NOTE: The following procedures relieve all fluid and air
pressure in the ProControl 1KS system. Use the proce-
dure appropriate for your system configuration.
Single Color Systems
1. While in Mix mode (gun triggered), shut off the fluid
supply pumps/pressure pots. Close all fluid shutoff
valves at the pump outlets.
2. With the gun triggered, push the manual override on
the A dose valve solenoid to relieve pressure. See
F
IG. 2.
NOTE: If a Dose Time alarm (E-7, E-8) occurs, clear
the alarm.
3. Do a complete system purge, following the instruc-
tions under Purging Using Recipe 0, in the Pro-
Control 1KS Operation Manual.
4. Shut off the fluid supply to the solvent purge valve
(SPV) and the air supply to the air purge valve
(APV), F
IG. 3.
5. With the gun triggered, push the manual override on
the A purge valve solenoid to relieve air and solvent
pressure. See F
IG. 2. Verify that solvent pressure is
reduced to 0.
NOTE: If a Purge Volume alarm (E-11) occurs, clear
the alarm.
Systems with Color Change and Dump
Valves
NOTE: This procedure relieves pressure through the
dump valves.
1. Complete all steps under Single Color Systems,
page 10.
2. Shut off all color and catalyst supplies to the valve
stacks.
3. Press and hold the dump valve A solenoid override,
F
IG. 2.
4. See F
IG. 2. Open the color change module. Using
the solenoid identification labels as a guide, press
and hold the override button on each color solenoid
until flow from dump valve A stops.
5. Press and hold the dump valve A solenoid override,
F
IG. 2.
6. Press and hold the A side (color) solvent solenoid
override until clean solvent comes from the dump
valve, then release.
7. Shutoff the solvent supply to the color/catalyst
change stack solvent valves.
8. Press and hold the A solvent solenoid override and
dump valve override until solvent flow from the
dump valve stops.
Your system must be grounded. See the Grounding
instructions in your ProControl 1KS Installation man-
ual.
To ensure proper grounding, resistance between Pro-
Control components and true earth ground must be
less than 1 ohm.
Relieve pressure when you stop spraying, before
changing spray tips, and before cleaning, checking, or
servicing equipment.
