Software alarm codes & displayed messages
Note: The alarm codes are intended only for fault finding and diagnostic purposes and are therefore not displayed directly to the
user. The alarm history log stores the last ten alarm codes in a "first in, first out" sequence once the maximum ten codes have been
exceeded.

Alaris® GW Volumetric Pump
Troubleshooting
Troubleshooting
Description
The pump has been left unattended
for 2 minutes and the infusion has not
started.
A bolus is being administered.
Communications failure with external
memory.
Fatal micro-controller failure.
Indicates end of infusion.
Motor controller is out of bounds.
Internal battery depleted /
disconnected.
Battery voltage threshold of 7v
reached. approximately 30 minutes of
running time left.
Upstream occlusion/air-in-line.
Downstream occlusion IV line
pressure exceeds limit threshold.
Indicates the pump is on hold.
Door is open whilst pump is infusing.
IV set used fails automatic set test
(incorrectly loaded).
Pressure sensor failure.
Power failure on AC power.
Safety circuit supply failure.
Motor is idle at very low infusion
rates.
Motor controller drive voltage limit
exceeded.
Incorrect number of encoder steps/
revolutions.
Encoder rotation time incorrect for
set rate.
Micro-controller stack overflow.
Communication failure with external
real time clock (RTC).
Hardware initiated motor brake.
No. of encoder revolutions too high.
Troubleshooting Guide

Press to temporarily silence for 1 minute.
boL display replaced with a volume counter during infusion.
Replace the Control PCB.
Replace the Control PCB. If pump does not subsequently
power up, replace the pressure sensor / encoder assembly.
Re-program the VTBI to resume infusion.
Check the mechanical parts around the gears / encoder for
obstructions.
Charge pump for 12 hours, check mains, battery fuses and
battery.
Charge pump for 12 hours, check mains, battery fuses and
battery.
Check AIL sensor function.
Check pressure and recalibrate.
Audible alarm after 2 minutes.
Check door magnet or sensor is flat against case.
Check the function of the pressure sensor.
Replace pressure sensor/encoder assembly. If error recurs,
replace the Control PCB.
Check cables around the power connector to Control PCB.
Ensure battery is connected. Check PSU Comms PCB and
replace if necessary. If error recurs replace Control PCB.
Ensure JP12 is firmly connected. Check voltage on real-
time clock battery. If low, power-up in technician mode to
recharge whilst connected to AC mains. If problem persists,
replace the Control PCB.
Check around the motor assembly, check for loose wires.
Check for mechanical obstruction around the gear area.
Check cabling to motor. Apply grease to pumping finger
cams as per Chapter 6. Replace the pressure sensor / encoder
assembly, if necessary. If error recurs, replace the Control PCB.
Check for damaged/distorted motor encoder wheel. Replace
the pressure sensor/encoder assembly, if necessary. If error
recurs, replace the Control PCB.
Withdraw the pump from service and ensure it is inspected
by a qualified service engineer.
