E21: No component A
transducer
E22: No component B
transducer
E23: High pressure
E24: Pressure imbalance
a. Check transducer connection J3 at motor control
board, page 29.
b. Swap transducer connections (J3, J8). If error
moves to transducer B (E22), replace transducer
A, page 30.
a. Check transducer connection J8 at motor control
board, page 29.
b. Swap transducer connections (J8, J3). If error
moves to transducer A (E21), replace transducer
B, page 30.
Relieve pressure. Verify low pressure with analog
gauges. Turn main power OFF then ON
. If error persists, do checks below.
a. Check jumper on motor control board J10, pins
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.
