Troubleshooting
P7000, P6000, TIVA, TCI & TIVA 36/106 1000SM00012 Issue 8
Use this troubleshooting guide to help identify the cause of errors and faults which may occur as a result of damage to
the pump or failure of an internal component. The following table lists the error codes and describes what action to take
to resolve the problem. A general fault diagnosis checklist is also provided. For information on alarm procedures and
messages, refer to the relevant
Directions For Use
(
DFU
).
Introduction
Error Codes
Error Failure Action/Replace
ER1 LINEAR SPEED Excessive linear movement
detected
Check for contamination or damage to the linear potentiometer.
Run the linear potentiometer self test using access code
176
. If not
linear, replace.
ER2 LINEAR SPEED Insufficient movement
detected
ER3 MOTOR Too many motor encoders Check mechanism is not slipping or opto flag loose.
Check motor and mechanism, replace as necessary.
Check connections between flexible circuit and control PCB.
Check flexible circuit, replace if faulty
Replace Control PCB. ER4 MOTOR Too few motor encoders
ER5 RAM Failure of RAM Check backup battery and replace if necessary.
Check EPROM socket, display spacers and torsion spring upgrades in
'Spare Parts Replacement Procedures' in Chapter 6.
ER6 WATCHDOG Watchdog failure too slow Replace Control PCB
ER7 WATCHDOG Watchdog failure too fast
ER8 HARDWARE Power on/off fault On Mark II hardware only. Power off occurred within 3 second power
down cycle of soft power off.
Fault in the soft power on/off circuitry.
ER9 MOTOR Motor direction Check motor wires are connected correctly.
Check RL1 and TR3 on Control PCB and replace as necessary.
Replace motor gearbox or Control PCB.
ER10 VREF VREF failure Replace PCB.
ER11 BEAM CURRENT
MONITORING
Beam failure Replace Beam bond assembly.
ER12 BEAM AMPLIFIER OFFSET Amp failure Replace Beam bond assembly.
Replace Control PCB.
ER13 MOTOR No motor rotation Check transistors TR6, TR10, TR11 on Control PCB and replace if faulty.
Replace motor gearbox.
Replace Control PCB.
ER14 MOTOR Motor rotating when
switched off
ER15 WATCHDOG Watchdog failure Check for radio frequency interference (RFI). replace Control PCB.
ER16 PLUNGER STUCK Plunger stuck at power up Check nothing is holding the plunger in and power on.
Replace flex circuit plunger optic.
Replace Control PCB.
ER17 HARDWARE Display fault Replace Display Board.
ER21 CRC FAILURE CRC failure Replace EPROM
Replace Control PCB.
ER22 STACK OVERFLOW Stack error Check for RFI.
Replace Control PCB.
ER23 OPTO FAILURE Opto failure Check optos in Self Test
123
. replace if faulty
Check opto signals to Control PCB, replace Control PCB if unable to
track fault.
If the nature of the problem is unclear, step through the
SELF TEST
routine to check that the main
functions of the pump are operating correctly. The
SELF TEST
routine exercises all the sensors in the
pump to verify that they are functioning accurately. See Chapter 3, 'Routine Maintenance' for details.
The
ERROR LOG
records the ten most recent malfunction codes. To review the
ERROR LOG
, go to the
SERVICE ACCESS
menu by entering the access code
