E-7: DOSE TIME A ALARM and E-8: DOSE TIME B ALARM
E-7: gun trigger input is active (AFS or Integration) and fewer than 31 A meter pulses were detected during the
dose time selected.
E-8: gun trigger input is active (AFS or Integration) and fewer than 31 B meter pulses were detected during the
dose time selected.
Cause Solution
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.
Dose time setting is too short for the current flow rate. Increase the dose time setting.
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 dif-
ference between the amount of fluid dispensed and the
flow meter volume displayed by the EasyKey. Clean or
repair meter as necessary. Also see meter manual
308778.
Follow Meter Calibration procedure, page 65.
Slow actuation of component A or B valves. See E-3: RATIO HIGH ALARM and E-4: RATIO LOW
ALARM, pages 82-83.
The supply pump is not turned on. Turn on the supply pump.
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.
System is in Mix mode with 0 volume entered for Min
Material Fill Volume (see Option Screen 1, page 32),
and Fuse F1 is blown.
Verify condition of fuse and replace if necessary. See
Repair-Parts manual.
