The pressure imbalance function (status code
24, page 43) detects conditions that can cause
off-ratio spray, such as loss of feed pres-
sure/supply, pump seal failure, clogged fluid
inlet filter, or a fluid leak.
The pressure imbalance default is factory-set
at 500 psi (3.5 MPa, 35 bar). For tighter ratio
error detection, select a lower value. For
looser detection or to avoid nuisance alarms,
select a higher value.
a. Turn main power switch OFF .
Motor must rotate counterclockwise
when viewed from shaft end. See Con-
nect electrical cord, page 25.
If display pressure is greater than
desired pressure, reduce the hydraulic
pressure and trigger gun to reduce
pressure.
