123	RUN CAPACITY	HIGH COMPRESSOR	123->Surge Prevention Override:	Check for high condenser water temperatures or
	LIMITED	LIFT	Lift Too High For Compressor.	low suction temperature.
124	RUN CAPACITY	MANUAL GUIDE	124->Run Capacity Limited:	Target guide vane point has been forced in
	LIMITED	VANE TARGET	Manual Guide Vane Target.	MAINSTAT screen. Release force to continue
				normal operation.
125	RUN CAPACITY	LOW DISCHARGE	No messages.	Check oil charge.
	LIMITED	SUPERHEAT		Check refrigerant charge.

*[LIMIT] is shown on the CVC/ICVC 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 pressure, temperature, voltage, etc., at which the control has recorded at the time of the fault con- dition.
