Operation
312065V 29
Change pressure imbalance
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.
Table 2Available Pressure Imbalance
Settings
1. Turn main power switch OFF .
2. Press and hold or , then turn main
power switch ON . Display will read dP500
for psi or dP_35 for bar.
3. Press or to select desired pressure
differential (100-999 in increments of 100 psi, or
7-70 in increments of 7 bar). See Table 3.
* Factor default setting.
4. Turn main power switch OFF to save
changes.
Spraying
1. Engage gun piston safety lock.
2. Close gun fluid manifold valves A and B.
3. Attach gun fluid manifold. Connect gun air line.
Open air line valve.
4. Set PRESSURE RELIEF/SPRAY valves (SA, SB) to
SPRAY .
5. Check that heat zones are on and temperatures are
on target, see Set temperatures, page 27.
6. Press motor to start motor and pumps.
