Description
The given compressor is not running and cannot run without
intervention. Further information is provided by the sub-mode:-
The compressor has been shutdown on a latching diagnostic.
The compressor has been shutdown due to a command from the
TechView Service Tool to be "locked out" and inoperative. This setting
is nonvolatile and operation can only be restored by using TechView
to "unlock" it.
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:
The compressor has been shutdown on a diagnostic that may clear
automatically.
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.
The given compressor is not currently running but can be expected to
start at any moment given that the proper conditions occur.
The given compressor is going through the necessary steps to allow
it to start. (This mode is short and transitory)
The given compressor is currently running. Further information is
provided by the sub-mode:
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.
The given compressor is currently running, but its capacity is being
actively limited by the controls. Further information is provided by the
sub-mode:
The compressor is running and its capacity is being limited by high
currents. The current limit setting is 120% RLA (to avoid overcurrent
trips) or lower as set by the compressor's "share" of the active -
current limit (demand limit) setting for the entire chiller.
