Diagnostics
This output is true whenever there is any active diagnostic that requires a
manual reset to clear, that affects either the Chiller, the Circuit, or any of the
Compressors on a circuit. This classifi cation does not include informational
diagnostics.
This output is true whenever there is any active diagnostic that could
automatically clear, that affects either the Chiller, the Circuit, or any of the
Compressors on a circuit. This classifi cation does not include informational
diagnostics.
This output is true whenever there is any diagnostic affecting any component,
whether latching or automatically clearing. This classifi cation does not include
informational diagnostics
This output is true whenever there is any diagnostic effecting Refrigerant Circuit
1, whether latching or automatically clearing, including diagnostics affecting the
entire chiller. This classifi cation does not include informational diagnostics.
This output is true whenever there is any diagnostic affecting Refrigerant Circuit
2 whether latching or automatically clearing, including diagnostics effecting the
entire chiller. This classifi cation does not include informational diagnostics.
This output is true whenever the chiller has been running in one of the
Unloading types of limit modes (Condenser, Evaporator, Current Limit or Phase
Imbalance Limit) continuously for the last 20 minutes.
This output is true whenever any compressors are running (or commanded
to be running) on Refrigerant Circuit 1, and false when no compressors are
commanded to be running on that circuit.
This output is true whenever any compressors are running (or commanded
to be running) on Refrigerant Circuit 2, and false when no compressors are
commanded to be running on that circuit.
This output is true whenever any compressors are running (or commanded to
be running) on the chiller and false when no compressors are commanded to be
running on the chiller.
This output is true whenever the chiller has reached maximum capacity or had
reached its maximum capacity and since that time has not fallen below 70%
average current relative to the rated ARI current for the chiller. The output is
false when the chiller falls below 70% average current and, since that time, had
not reestablished maximum capacity.
