Immediate Latch a. The Suction Refrigerant Pressure (or either of the compressor
suction pressures) dropped below 10 Psia just prior to compressor
start (after EXV preposition). b. The pressure fell below 16 Psia while
running after the ignore time had expired, or fell below 10 Psia (or 5
Psia in software prior to Oct'02) before the ignore time had expired.
The ignore time is function of outdoor air temperature. Note: Part b. is
identical to Low Evaporator Refrigerant Temperature diagnostic except
for the trip integral and trip point settings.

Immediate Latch Compressor current exceeded overload time vs. trip characteristic.
For A/C products Must trip = 140% RLA, Must hold=125%, nominal
trip 132.5% in 30 seconds

Immediate Latch Memory error criteria TBD
Info Latch MP has determined there was an error with the previous power down
store. Starts and Hours may have been lost for the last 24 hours.
Immediate Latch MP has an invalid configuration based on the current software
installed
Info Latch MP has determined there was an error with a block in the Non-Volatile
memory. Check settings.
Info Latch MP has determined there was an error in a sector of the Non-Volatile
memory and it was reformatted. Check settings.
Info NonLatch 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 Historic
Diagnostic List in TechView
Immediate Latch The Intermediate Oil Pressure Transducer for this cprsr is reading a
pressure either above its respective circuit's Condenser Pressure by
15 Psia or more, , or below its respective Suction Pressure 10 Psia or
more for 30 seconds continuously.
