4.1 Events and modes
Various events cause mode changes. Events can include: elapsed time decremented to
zero, amperage reaching a programmed value, an over-temperature condition, an open
boat condition, loss of interlock continuity, or user interaction with front panel or pendant
keys.
Following are specific events and their effects on the various modes.
Table 4-1 Manual Mode
Event From To Description
START key O.F.F. mode MAN mode Starts Manual mode if user programmed ramp minutes
equals zero. MAN indicator is illuminated. The large display
shows requested current from the T3000. The INC and DEC
keys are used to change the requested value that is
displayed. The pendant arrow keys provide this same
function. The small display shows alternating minute and
kilowatt values. Minute and kilowatt values can be
differentiated by the illumination of the Kw and MIN
indicators and by the position of the decimal point (x.xx=Kw
format / xx.x=MIN format). In Manual mode, the time counts
up, measuring elapsed time. Upon entry into the Manual
mode, previous elapsed time values, if any, are reset to
zero.
INC + DEC MAN mode
minutes > 0 MAN mode
minutes = 0 Elapsed time can be reset to zero by pressing both the INC
and DEC keys simultaneously. The pendant arrow keys
provide this same function.
