Condition / Response
When the fixed speed compressor XY was
commanded Off its proving input failed to prove Off
for 6 continuous seconds.
Circuit X compressors will be commanded Off.
Condenser fan operation and EXV valve control will
continue in case the compressor is physically On.
When the fixed speed compressor XY was
commanded On its proving input failed to prove On.
Circuit X operation will be inhibited.
When the fixed speed compressor XY has been OFF,
and its proving input has proven OFF, its proving
input unexpectedly proves On for 6 continuous
seconds.
It is assumed that a compressor has started un-
commanded, the diagnostic will be generated and the
circuit will be shutdown.
Circuit X operation will be inhibited.
A High condensate level was detected.
This diagnostic will be generated, and the unit will
shut down, if a high condensate level is detected for
the first two times within a 72 hour period. The
diagnostic will reset and the unit will be allowed to
start if the condensate level drops below the trip
point.
This diagnostic indicates a problem with the
mechanical float valve or the water drain piping.
However it is assumed that this is a temporary
problem and does not require service. If a third high
condensate level is detected within 72 a period a
Condensate Overflow Lockout diagnostic is
generated.
Note: VOM/EOM Behavior - During these modes this
diagnostic changes behavior to a warning
diagnostic and the active mode will be honored.
A High condensate level was detected.
The lockout Will be generated if a high condensate
level is detected a third time within a 72 hour period.
This is indicating a recurring problem with the
mechanical float valve or the water drain and may
require service.
Note: VOM/EOM Behavior - During these modes this
diagnostic is not generated and the active mode
will be honored.
If the Discharge Air Temperature exceeds 200F then
an Immediate Stop will be generated.
This must be from the Local Discharge Air
Temperature sensor (not an arbitrated value). Check
unit airflow, supply fan operation, sensor reading.
Unit operation is inhibited.
