Compressor Modes Description
Top Level Mode
Sub-modes
Stopped The given compressor is not running and cannot run without inter-
vention. Further information is provided by the sub-mode:
Diagnostic Shutdown - Manual Reset The compressor has been shutdown on a latching diagnostic.
Service Tool Lockout The compressor has been shutdown due to a command from the
TechView Service Tool to be "locked out" and inoperative. This set-
ting is nonvolatile and operation can only be restored by using Tech-
View to "unlock" it.
Other sub-modes are possible in conjunction with at least one of
the above modes - See items below for their descriptions:
Diagnostic Shutdown - Auto Reset
Restart Inhibit
Run Inhibit The given compressor 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:
Diagnostic Shutdown - Auto Reset The compressor has been shutdown on a diagnostic that may clear
automatically.
Restart Inhibit The compressor is currently unable to start due to its restart inhibit
timer. A given compressor is not allowed to start until 5 minutes
has expired since its last start.
Auto The given compressor is not currently running but can be expected
to start at any moment given that the proper conditions occur.
No Sub Modes
Starting The given compressor is going through the necessary steps to
allow it to start. (This mode is short and transitory)
No Sub Modes
Running The given compressor is currently running. Further information is
provided by the sub-mode:
Establishing Min. Capacity - High Oil Temp The compressor is running and is being forced loaded to its step
load point, without regard to the leaving water temperature control,
to prevent tripping on high oil temperature.
Running - Limited The given compressor is currently running, but its capacity is being
actively limited by the controls. Further information is provided by
the sub-mode:
Capacity Limited by High Current The compressor is running and its capacity is being limited by high
currents. The current limit setting is 120% RLA (to avoid overcur-
rent trips) or lower as set by the compressor's "share" of the active
current limit (demand limit) setting for the entire chiller.
Capacity Limited by Phase Unbalance The compressor is running and its capacity is being limited by
excessive phase current unbalance.
Shutting Down The given compressor is still running but shutdown is imminent.
The compressor is going through either a run-unload mode or is the
active compressor in the operational pumpdown cycle for its circuit.
Shutdown is either normal (no sub-mode displayed) or due the fol-
lowing sub-modes:
Diagnostic Shutdown - Manual Reset The compressor is in the process of shutdown due to a latching
diagnostic.
