The 9800A does not display the last transaction during an AC power failure. This problem
pertains only to 9800A’s equipped with a battery back-up power supply.
Possible Cause
Checks Corrective Action
Battery not fully charged or
defective power supply PCB. If the 9800A had been off for a
very long time, the battery
probably isn’t fully charged.
After AC power is restored,
allow the 9800A to run for 24
to 36 hours, then turn AC
power off and make sure the
last transaction is displayed for
15 minutes minimum. Replace the power supply if
charging did not fix the
problem.
9800A does not display electronic totalizer data.
Possible Cause
Checks Corrective Action
Pump Handles are on. Check if pump handles are on. Turn pump handles off, if on.
Possible misalignment of
totalizer switch and magnet. Check alignment. Realign if needed.
Defective actuator. None. Replace actuator.
Defective totalizer sensor or
defective CPU PCB. Remove the totalizer cable
assembly from P6 of the CPU
PCB. Short the two pins
together on P6 of the CPU
PCB. Replace the totalizer cable
assembly if shorting P6
causes totalizer data to
display.
Replace the CPU PCB if
shorting P6 does not cause
totalizer data to display.
NOTE: Changing the pulser
rate switches may require
replacement of your Weights
and Measures seal.
Electronic totalizer data looks scrambled after a power failure.
Possible Cause
Checks Corrective Action
RAM memory IC not retaining
data. None. Replace RAM memory IC.
