All The main processor has successfully come out of a
reset and built its application. A reset may have been
due to a power up, installing new software or
configuration. This diagnostic is immediately and
automatically cleared and thus can only be seen in the

The Starter module status reported back that it is
stopped when the MP thinks it should be running and
no Starter diagnostic exist. This diagnostic will be
logged in the active buffer and then automatically
cleared. This diagnostic could be caused by intermittent
communication problems from the Starter to the MP, or
due to misbinding.

The inferred Saturated Evap Refrigerant Temperature
(calculated from suction pressure transducer dropped
below the Low Refrigerant Temperature Cutout Setpoint
for 1125°F-sec (25°F-sec max rate) while the circuit was
running. The minimum LRTC setpoint is -5°F (18.7 Psia)
the point at which oil separates from the refrigerant.
During the time that the trip integral is non zero, the
unload solenoid(s) of the running compressors on the
circuit, shall be energized continuously and the load
solenoid shall be off. Normal load/unload operation will
be resumed if the trip integral decays to zero by temps
above the cutout setpoint. The integral is held
nonvolatily though power down, is continuously
calculated, and can decay during the circuit's off cycle as
conditions warrant.
