. If error persists, do checks below.

7-10, page 28.
b. Replace motor control board, page 28.
A and B pressures are imbalanced. Secure
bleed lines in grounded waste containers, or
route back to respective component A or B sup-
ply drum. Reduce pressure of higher component
by
slightly
turning PRESSURE RELIEF/SPRAY
valve for that component toward PRESSURE
RELIEF, until gauges show balanced pressures.
Turn PRESSURE RELIEF/SPRAY valve only
enough to balance pressure. If you turn it com-
pletely, all pressure will bleed off.
Jog and park modes may be run with pressure
imbalance.
E24 can be an alarm or a warning, as desired.
Set DIP switch on motor control board ON for
alarm, OFF for warning. See page 28.
