System Errors
58 3A0868G
QTA1 or QTB1
Dose Time Error
The gun trigger is active, but
no A pump (QTA1) or B pump
(QTB1) movement is detected
during the dose time selected.
System is in Mix mode and gun is only par-
tially triggered, allowing air but no fluid to
pass through gun.
Fully trigger the gun.
Fluid flow rate is too low. Increase flow rate.
Slow actuation of component A or B valves. See Ratio Low Error and Ratio High
Error, pages 56-57.
A or B pump has no air pressure. Verify that main air supply is turned
on and valves are open.
There is an air leak downstream from the
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
Leak Error
Pump A (QLAX) or Pump B
(QLBX) is running with all
valves closed.
A or B dose valve leak Replace valve needle and seat.
A or B pump is not seating and continues
to move/creep.
Replace pump packings, balls, and
seats.
DJA1 or DJB1
Linear Sensor Error
System does not detect the
pump A (DJA1) or pump B
(DJB1) linear position sensor,
or has an invalid position read-
ing.
Sensor not recognized by system.
Verify that sensor is plugged in. Verify
that sensor and AFCM are opera-
tional. Verify cable connections.
Replace any malfunctioning compo-
nent.
Magnet fell off.
Replace magnet and holder on top
side of air motor piston.
Sensor readings are out of range.
Verify that the sensor is threaded
down
completely.
DKA1 or DKB1
Reed Switch Error
System does not detect the
pump A (DKA1) or Pump B
(DKB1) reed switch sensor, or
detects an invalid state.
Reed switch installed backward.
Flip reed switch 180 degrees to align
with magnet in air valve.
Reed switches are stuck, or both reed
switches are on at once
Verify cable is connected on both
ends. Verify that reed switch, cable,
and AFCM are operational. Replace
any malfunctioning component.
Magnet in air valve not functioning prop-
erly.
Verify that magnet is installed prop-
erly and is operational.
P4A1 or P4B1
Pressure High Error
System detects a high pres-
sure reading on pump A
(P4A1) or pump B (P4B1).
Pump air pressure is set too high.
Reduce pressure on air supply to sys-
tem or pumps.
Thermal expansion occurring in lines.
Relieve pressure if system has been
idle. Decrease environmental
temperature.
Pressure transducer malfunction.
Replace transducer. Verify that cable
and AFCM are operational.
P6A1 or P6B1
Pressure Transducer Error
System does not detect pres-
sure transducer A (P6A1) or
pressure transducer B (P6B1).
Pressure transducer malfunction.
Replace transducer. Verify that cable
and AFCM are operational.
