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
