QTA1, QTA2, QTA3, or
QTB1
Dose Time Error
The gun trigger is active, but
no A pulses (QTA1, QTA2,
QTA3) or no B pulses (QTB1)
are detected during the dose
time selected.
System is in Mix mode and gun is only
partially triggered, allowing air but no fluid
to pass through gun.
Fully trigger the gun.
Fluid flow rate is too low. Increase flow rate.
Flow meter or cable failed or flow meter
clogged.
To check meter sensor operation,
remove meter cap to expose sensor.
Pass a ferrous metal tool in front of the
sensor.
If there is a meter or cable failure, you
will see a large difference between the
amount of fluid dispensed and the flow
meter volume displayed by the Display
Module. Clean or repair meter as nec-
essary.
Slow actuation of component A or B
valves.
See Ratio Low Error and Ratio High
Error, pages 61-62.
The supply pump is not turned on. Turn on the supply pump.

air flow switch.
Check the air lines for leaks and repair.
The air flow switch is stuck open. Clean or replace air flow switch.
QLAX or QLBX

(QLBX) measures fluid with all
valves closed.
Pressure on circulation system is fluctu-
ating and generating meter pulses.
Replace check valve in front of meter.
Valve is leaking. Replace valve seat, valve, or valve
seal.
Gun, manifold, or line is leaking. Repair leak downstream of meters.
