not in place.
See Voltage Loss
Troubleshooting, page 75 .
The ES request input does not
recognize a signal and does not
raise the ground rod. Use the Status screen to see
whether the system detects
the ES request input. See
Status Screen 1, page 50 and
Status Screen 3, page 51 .
Low or no spraying voltage.
Incorrect voltage level display Check system voltage using a
probe (236003).
Calibrate the bleed resistor as
described in
Calibrate the Bleed
Resistor, page 58 .
Check or replace the kV
board as described in
Replace a kV Board, page 105 .

Paint goes backward toward the
paint supply. Faulty inlet valve and check valve. With the shuttle down, test the
Shuttle Fluid In, Pump Fluid In, and
Pump Pressure valves individually
on Maintenance Screen 4. If fluid
is in valves at the same time as
there is pump pressure, this can
result in fluid back-flowing if a
check valve is not present.
See Maintenance 4: Fluid Valve
Resets and Test, page 61 .
Check for a leaky check valve.
