Table 7.2 Error code related troubleshooting chart
Code Error/event Possible cause/solution
10 CPU1 ROM checksum error Faulty U17 Chip on CPU/power supply board.
12/13 NV RAM error Pump must be reinitialized, see page 7-25.
14 Main audio alarm failure Faulty speaker, faulty audio chip (U16), faulty capacitor (C18), or
transistor Q8, Q9, Q12, and or
Q13 (all on CPU/power supply board).
19 Air detect test failure Open wires to optical emitter/detector, faulty emitter/detector, faulty
transistors Q102, Q106 on I/O Board, contamination/debris blocking
optical emitter/ detector path.
20 No flow above pump circuit Empty bag contact out of adjustment (must be calibrated at the
error Service Centre).
21 Display board communication Fluid contamination on Display board - replace board
error and perform ‘Occlusion Alarm Adjustment’. Faulty resistors R29,
R87, R92, R93 on CPU/power supply board, faulty ribbon cable
connection (P200) on CPU /power supply board.
22 Display digit, 0-9 Voltage to LED’s on display board too high or too low, Replace
display board and perform ‘Occlusion Alarm Adjustment’.
23 Display LED error, 0-6 Either Hold, Run, AC, Battery, Primary, or Secondary LED faulty.
28 Motor stall/interrupter Loose motor coupler.
31 Micro/Macro discrepancy Incorrect jumper configuration - jumper JP10 should be removed
error /open for 3000/500, intact/shorted for 3100/505 (if the JP10 jumper
configuration must be changed, the pump history must be
reconfigured at the Service Centre).
32 Pressure plate position switch Check Pressure plate position switch calibration (refer to
change during RUN pressure plate position sensor breakopenpoint in functional test),
inspect door and hinges for damage.
33 Corrupted triple redundant Pump must be reinitialized, see page 7-25.
variable in NVRAM
38 NV RAM error Pump must be reinitialized, see page 7-25.
40 Pressure plate position Check pressure plate position switch calibration (refer to pressure
switch = 1 when door is open pressure plate position sensor breakopenpoint in functional test).
42 Safety clip in place when door Cam housing switch out of adjustment.
43 Service due Service due date reached. Service pump/reset service due date.
65 Stop pumping - occlusion Refer to ‘Occlusion alarm adjustment’.
67 Stop pumping - no flow Empty bag contact out of adjustment (must be calibrated at the
above pump Service Centre).
69 Stop pumping - loading Check pressure plate position switch calibration (refer to pressure
problem plate position sensor breakopen point in functional test), check
motor connection to I/O board at P103.
72 Stop pumping - Safety clip Check motor connection to I/O board at P103, check wire connection
to Safety clip switch.
