* [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.

Sensor Alert
High Discharge Temp CMPD [VALUE]
exceeded limit of
[LIMIT*]. Check dis-
charge temperature. Discharge temperature exceeded the alert
threshold. Check entering condenser water
temperature.
Sensor Alert
High Bearing Tempera-
ture MTRB [VALUE]
exceeded limit of
[LIMIT*]. Check thrust
bearing temperature. Thrust bearing temperature exceeded the
alert threshold. Check for closed valves,
improper oil level or temperatures.
Condenser
Pressure Alert
Pump Relay Energized CRP High Condenser
Pressure [LIMIT*].
Pump energized to
reduce pressure. Check ambient conditions. Check con-
denser pressure for accuracy.
Recycle Alert Excessive Recycle
Starts Excessive recycle
starts.
The machine load is too small to keep the
machine on line and there have been more
than 5 restarts in 4 hours. Increase
machine load, adjust hot gas bypass,
increase RECYCLE RESTART DELTA T.
