63 Lithium backup battery voltage is
too low to back up the memories.
Check connector CN304 for
proper connection and continuity.
Plug CN304 in firmly.
Replace lithium backup battery.
Replace CPU board.
Replace Sensor board.
64 Malfunction in A/D converter
circuitry. A/D conversion for 0
through 3 channels did not
complete in 144 mS.
Turn pump off and back on. If failure recurs, replace CPU
board.
Replace Sensor board.
65 Malfunction in A/D converter
circuitry. A/D conversion for 4
through 7 channels did not
complete in 144 mS.
Turn pump off and back on. If failure recurs, replace CPU
board.
Replace Sensor board.
66 Supply voltage of CPU circuitry is
too high.
Turn pump off and back on. If failure recurs, replace Sensor
board.
67 Supply voltage of CPU circuitry is
too low.
Turn pump off and back on. If failure recurs, replace Sensor
board.
68 Malfunction in A/D converter
circuitry. A/D conversion for
channels 8 and 9 did not complete
in 72 mS.
Turn pump off and back on. If failure recurs, replace CPU
board.
Replace Sensor board.
69 Abnormal battery recharging
voltage.
Check calibration of DC Power
Supply board.
Recalibrate the board. If failure
recurs, replace CPU board.
70 Data in duplicate memory areas
does not agree.
Turn pump off and back on.
Check connections on CPU board.
If failure recurs, replace CPU
board.
71 Slave CPU received no data from
Master CPU.
Turn pump off and back on.
Check connections on CPU board.
If failure recurs, replace CPU
board.
72 Slave CPU received undefined
data 4 times from Master CPU.
Turn pump off and back on.
Check connections on CPU board.
If failure recurs, replace CPU
board.
73 Overcurrent to motor. Motor
current exceeds 1 A.
Check for loose motor coupler.
Check that connector CN201 is
seated firmly.
Check for loose encoder wheel.
Check for blown fuse F201 and
F202.
Apply a trace of Loctite 211 or
222 to coupling set screws and
tighten them to 5 kgf-cm (4.3
in-lb).
Secure encoder wheel.
Plug CN201 firmly.
Replace fuse if necessary.
Replace Sensor board.
Replace CPU board.
