PRIMARY MESSAGE
SECONDARY MESSAGE
ALARM MESSAGE/PRIMARY CAUSE
ADDITIONAL CAUSE/REMEDY
RUN CAPACITY LIMITED
HIGH CONDENSER PRESSURE
CRP [VALUE] exceeded limit of [LIMIT]*.
Condenser pressure override.
See Capacity Overrides, Table 4.
Correct operating condition, modify set-
point, or release override.
RUN CAPACITY LIMITED
HIGH MOTOR TEMPERATURE
MTRW [VALUE] exceeded limit of [LIMIT]*.
Motor temperature override.
RUN CAPACITY LIMITED
LOW EVAP REFRIG TEMP
ERT [VALUE] exceeded limit of [LIMIT]*. Check
refrigerant charge level.
RUN CAPACITY LIMITED
HIGH COMPRESSOR LIFT
Surge Prevention Override; lift too high for
compressor.
RUN CAPACITY LIMITED
MANUAL GUIDE VANE TARGET
GV
TRG Run Capacity Limited: Manual guide
vane target.
*[LIMIT] is shown on the LID as the temperature, pressure, voltage, etc., set point predefined or selected by the operator as an override, alert, or alarm condition. [VALUE]
is the actual temperature, pressure, voltage, etc., at which the control tripped.
