Appendix B: Warmer fault code table
Warmer Fault Code Displayed on Controller
# Name Description
10 Fluid out temperature sensor reading failure Sensor is reading a temperature outside the normal operating range or has been determined to be open or
shorted.
11 Fluid in temperature sensor reading failure Sensor is reading a temperature outside the normal operating range or has been determined to be open or
shorted.
12 Heater out temperature sensor reading failure Sensor is reading a temperature outside the normal operating range or has been determined to be open or
shorted.
13 Heater in temperature sensor reading failure Sensor is reading a temperature outside the normal operating range or has been determined to be open or
shorted.
20 Average VCC failure Warmer internal operating voltage is out of range.
21 Average TRef failure Warmer internal reference voltage is out of range.
30 RAM memory test failure Data is written to and then read from RAM and veried at power up.
31 ROM memory test failure A check sum is done on the memory at power up.
32 Flash memory test failure A check sum is done on the memory at power up.
40 OT fuse or low battery failure This fault code is indicative of a non-recoverable heater over-temperature, fuse open, condition.
41 Covers failure This fault occurs every time the covers are opened while heating.
50 Heater MOSFET failure or Circuit Breaker Trip This fault code is indicative of a Heater Over-temperature protection fault.
52 Clock oscillator failure This fault is activated if the external crystal oscillator fails.
53 Internal temperature ˚C failure This failure is indicative of the Warmer being too hot inside and is caused by operating in an environment that
is too warm.
54 Error clock failure A system clock failure has occurred.
99 General system fault The Controller is unable to determine the fault.
Please follow these instructions if any of the fault conditions listed above are displayed on the controller:
1. Thoroughly clean the warmer using the instructions provided in this manual (refer to section titled “Cleaning the enFlow IV uid/blood warming system
components.”)
2. Evaluate the exterior of the device. If there is any physical damage to the housings or power cord that would allow uid ingress into the device, or if
the heating element surface is physically damaged, deformed, or breached, then remove the device from service and return the device using the RGA
instructions provided in this manual (refer to “Servicing the enFlow IV uid/blood warming system components.”)
3. If there is no obvious physical damage to the device, then evaluate the device using the instructions in Appendix E and Appendix F.
4. If the device passes the evaluation, then it may be returned to normal use.
