setting (optional)
The pressure imbalance function (status code 24)
detects conditions that can cause off-ratio spray, such
as loss of feed pressure/supply, pump seal failure,
clogged fluid inlet filter, or a fluid leak.
NOTE: Code 24 (pressure imbalance) is set to an alarm
as the default. To change to a warning, see Reactor
Repair-Parts manual 312066.
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.
