Table 4-2 Ramp Mode
Event From To Description
START key O.F.F. mode RAMP mode Starts Ramp mode if user programmed
ramp minutes does not equal zero. The
large display shows requested current from
the T3000. The requested current value is
based upon the user programmed values
of Ramp current and Ramp minutes. The
Ramp current is divided across the Ramp
minutes and is distributed in a linear
progression increasing from zero to the
user programmed value of Ramp current
just as the Ramp minutes value is reached.
For example, at 25% of elapsed time, the
current request will be at 25% of the
programmed value of Ramp current. 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). Upon entry into
the Ramp mode, the time counts down
from the user programmed value of Ramp
minutes, measuring remaining time until
zero is reached.
Ramp minutes=0 RAMP mode MAN mode Ends Ramp mode and automatically starts
the Manual mode (see Manual mode
START).
STOP key RAMP mode O.F.F. mode Ends Ramp mode. The pendant STOP key
provides this same function.
START key RAMP mode MAN mode Ends Ramp mode and automatically starts
the Manual mode (see Manual mode
START) retaining the last current value
held in the Ramp mode.
Err: open boat RAMP mode O.F.F. mode Error ends RAMP mode.
Err: hot “ O.F.F. mode “
INTERLOCK RAMP mode O.F.F. mode Interlock at logical high ends RAMP mode.
