Name Description
Sensor is reading a temperature outside the
normal operating range or has been determined
to be open or shorted.
Sensor is reading a temperature outside the
normal operating range or has been determined
to be open or shorted.
Sensor is reading a temperature outside the
normal operating range or has been determined
to be open or shorted.
Sensor is reading a temperature outside the
normal operating range or has been determined
to be open or shorted.
Warmer internal operating voltage is out of range.
Warmer internal reference voltage is out of range.
Data is written to and then read from RAM and
verified at power up.
A check sum is done on the memory at power up.
A check sum is done on the memory at power up.
This is a dual function failure. First, if the Warmer
is powered either by the battery or the
Controller/AC Power Pack and the output voltage
is too low, this fault code will be activated. It is
accompanied by a YELLOW power light on the
Warmer. Second, if this fault code occurs while
the Warmer is running from the Controller/AC
Power Pack and the RED power LED is flashing, it
is indicative of an Over- temperature fuse open
circuited.
This fault occurs every time the covers are opened
while heating.
Heater Control MOSFETs are checked to ensure
that they are performing as commanded by the
software. If the MOSFET does not respond as the
software has commanded, this fault is generated.
Test purposes only
This fault is active if the external crystal oscillator
fails.
This failure is indicative of it being too hot inside
the Warmer and is caused by operating in an
environment that is too warm.
A system clock failure has occurred.
The Controller/AC Power Pack is unable to
determine the fault.
