Pressing ENTER key will take the interface down into a hierarchy of
parameter selection menus (act, treat, days, probe and spnew setting).
Pressing ENTER key in any of the parameter selection menus com-
mits to selection of the currently displayed parameter and causes the
interface to descend into the next parameter selection menu. All
parameter selection menus alternate between a blank display and the
current selection in the right hand display.
Pressing CODE SELECT key in a selection menu cancels the current
selection activity and ascends back up to the next higher selection
menu (or to Cd51 display mode if that is the next higher).
If the operator does not press any key for five seconds the interface
reverts to normal system display and the current selection menu is
cancelled, but any previously committed changes are retained.
Available parameters and parameter ranges are a function of configu-
ration options and previously selected parameters as indicated
above.
Parameter with the exception of “Act” may not be altered if Cd51 is re-
entered if “Act” is “On”. When ACT has completed including reaching
the new setpoint “done” on the left display and the MONTH DAY of
completion on the right display will be displayed as the second entry
in the menu. Turning ACT off clears this entry. This action also resets
Cd51 to initial time remaining. ACT must then be turned on to view or
modify the additional parameters.
Whenever any auto Pre-trip test or Trip Start is initiated, ACT mode
goes to OFF.
