Mix Manifold Valve Settings
To open dose or purge valves, turn hex nut (E) counter-
clockwise. To close, turn clockwise. See Table 7 and
F
IG. 59.
Table 6: Dynamic Dosing Troubleshooting Guide
(for complete system troubleshooting, see Table 11 beginning on page 83)
Warning/Alarm Message Solution
B Pressure Too Low (see F
IG. 56) • Increase B pressure.
• Clean restrictor or use a larger size.
• Verify B valve is opening properly.
B Pressure Too High • Increase A pressure or decrease B pressure.
• Use a smaller restrictor.
Off Ratio Low • Increase A pressure or decrease B pressure.
• Use a smaller restrictor.
Off Ratio High • Increase B pressure.
• Clean restrictor or use a larger size.
• Verify B valve is opening properly.

Valve Setting Function
Dose
(F
IG. 59)
Hex nut (E) 1-1/4 turns out
from fully closed
Limits maximum fluid flow rate into integrator
and minimizes valve response time.
Purge
(F
IG. 59)
Hex nut (E) 1-1/4 turns out
from fully closed
Limits maximum fluid flow rate into integrator
and minimizes valve response time.
Shutoff
(SVA and
SVB, F
IG. 67)
Fully open during Run/Mix
operation
Closes component A and B ports to integrator
during ratio check or meter calibration. Open
ports during Run/Mix operation.
Sampling
(RVA and
RVB, F
IG.
67)
Fully closed during Run/Mix
operation
Open to dispense component A and B while
calibrating meters. Do not open sampling
valves unless fluid shutoff valves are closed.
