Description
The given circuit is not running and cannot run without intervention.
Further information is provided by the sub-mode:
The circuit is manually locked out by the circuit lockout setting - the
nonvolatile lockout setting is accessible through either the DynaView
or TechView.
The circuit has been shutdown on a latching diagnostic.
The given circuit is currently being inhibited from starting (and
running), but may be allowed to start if the inhibiting or diagnostic
condition is cleared. Further information is provided by the sub-
mode:
The circuit has been shutdown on a diagnostic that may clear
automatically.
The circuit is inhibited from starting (and running) by its "external
circuit lockout" hardwired input.
The circuit is inhibited from starting (and running) by command from
a Building Automation System via the digital communication link
(com 3 or com 5).
The given circuit is not currently running but can be expected to start
at any moment given that the proper conditions and interlocks are
satisfied.
The given circuit is going through the necessary steps to allow the
lead compressor on that circuit to start.
At least one compressor on the given circuit is currently running.
Further information is provided by the sub-mode:
The circuit is experiencing low system differential pressure and is
being force loaded, irregardless Chilled Water Temperature Control, to
develop pressure sooner.
At least one compressor on the given circuit is currently running, but
the capacity of the circuit is being actively limited by the controls.
Further information is provided by the sub-mode:
The circuit is experiencing condenser pressures at or near the
condenser limit setting. Compressors on the circuit will be unloaded
to prevent exceeding the limits.
The circuit is experiencing saturated evaporator temperatures at or
near the Low Refrigerant Temperature Cutout setting. Compressors on
the circuit will be unloaded to prevent tripping.
