This message indicates the system oil pressure, suc-
tion pressure, and discharge pressure at the time of the
fault.
This message shows the system oil temperature, suction
temperature, and discharge temperature at the time of
the fault.
These messages indicate compressor suction gas sat-
u ra tion temperature and superheat at the time of the
fault.
This message indicates compressor discharge gas sat-
u ra tion temperature and superheat at the time of the
fault.
This message indicates the compressor slide valve po-
si tion at the time of the fault. 0 steps equals minimum
capacity and 75 steps equals fully loaded.
This message indicates the EEV preheat % and the suc-
tion superheat.
This message, which is only displayed if the unit is in
R-407C mode, indicates the refrigerant temperature at
the inlet of the evaporator.

This message indicates the EEV PILOT So le noid Valve
and the economizer Thermal Expansion Valve So le noid
Valve position: ON = Energized / OFF = De-En er gized
(OFF) at the time of the fault.
This message indicates the stage of condenser fan op-
er a tion on the system and the status of the com pres sor
heat er at the time of the fault. See Section 8.4 for de tails
of fan staging.
This message indicate whether the WYE-DELTA out-
put to the compressor was energized at the time of the
fault
This message indicates whether the discharge cooling
solenoid was energized at the time of the fault and if the
WYE-DELTA output to the compressor was energized.
