SECTION 5 - DISPLAY MESSAGES
Evaporator Refrigerant Temp Out of Range
The Evaporator Refrigerant Temperature RTD is indi-
cating a resistance that is less than 60 Ohm, or greater
than 160 Ohm. This is outside the normal operating
range of the temperature RTD. This is generally indi-
cates a defective sensor, shorted or loose wire.
Evaporator Refrigerant Temp Temp Low
This message is generated when there is a warning of
an impending trip at 35°F.
Evaporator Refrigerant Temp Very Low
This message is generated when there is a warning of
an impending trip at 34°F.
Primary Discharge Temp Out of Range
The Primary Discharge Temperature RTD is indicating
a resistance that is less than 60 Ohm, or greater than
160 Ohm. This is outside the normal operating range
of the temperature RTD. This is generally indicates a
defective sensor, shorted or loose wire.
Primary Discharge Temp Low
This message is generated when there is a warning of
low discharge superheat.
Primary Discharge Temp Very Low
This message is generated when there is a danger of a
defective sensor.
Primary Discharge Temp High
This message is generated when there is a warning of
an impending trip greater than 210°F.
Primary Discharge Temp Very High
This message is generated when there is a danger con-
dition above 220°F.
Secondary Discharge Temp Out of Range
The Secondary Discharge Temperature RTD is indicat-
ing a resistance that is less than 60 Ohm, or greater
than 160 Ohm. This is outside the normal operating
range of the temperature RTD. This is generally indi-
cates a defective sensor, shorted or loose wire.
Secondary Discharge Temp Low
This message is generated when there is a warning of
low discharge superheat.
Secondary Discharge Temp Very Low
This message is generated when there is a danger of a
defective sensor.
Secondary Discharge Temp High
This message is generated when there is an impending
trip of greater than 210°F.
Secondary Discharge Temp Very High
This message is generated when there is a danger con-
dition above 220°F.
Subcooler Dropleg Temp Out of Range
The Subcooler Dropleg Temperature RTD is indicating
a resistance that is less than 60 Ohm, or greater than
160 Ohm. This is outside the normal operating range
of the temperature RTD. This is generally indicates a
defective sensor, shorted or loose wire.
Oil Sump Temp Out of Range
The Oil Sump Temperature RTD is indicating a re-
sistance that is less than 60 Ohm, or greater than 160
Ohm. This is outside the normal operating range of the
temperature RTD. This is generally indicates a defec-
tive sensor, shorted or loose wire.
Oil Sump Temp Low
This message is generated when there is a warning of
an impending trip less than 70°F, inicating that there is
too much refrigerant dissolved in the oil.
Oil Sump Temp Very Low
This message is generated when there is a low tem-
perature of less than 55°F.
Oil Sump Temp High
This message is generated when there is a warning of
an impending trip greater than 180°F.
Oil Sump Temp Very High
This message is generated when there is a trip caused
by a temperature greater than 185°F.
