In the following discussion, the fine adjust knob
15
can optionally
be used for ramp rate adjustment if the persistent switch is
heated (or if no persistent switch is installed). If the user attempts
to edit ramp rate segments using the fine adjust knob while an
installed switch is cooled, the Model 430 Programmer will
produce one beep to indicate an error
16
. Similarly, if the switch is
heated (or no switch is installed), attempting to use the fine
adjust knob for PSw P/S ramp rate will produce one beep
17
.
Pressing
SHIFT
and then
RAMP RATE
will access the ramp rate
menu. The numeric and
ENTER
keys (or the fine adjust knob)
are used to set the segment #1 ramp rate to a value of 0.2 A/sec.
The right arrow key is pressed once to access the segment #1
range display. The numeric and
ENTER
keys (or fine adjust
knob) are used to set the segment #1 current range upper bound
to a value of 55 A.
Pressing the right arrow key accesses the next (second)
segment ramp-rate display. The segment #2 ramp rate is set to a
value of 0.1 A/sec.
The right arrow key is pressed once to access the segment #2
range display. The segment #2 current range upper bound is set
to a value of 58 A.
15. See page 55.
16. Since the PSw P/S ramp rate is active in that scenario, and not the segmented ramp rate.
17. Since the standard segmented ramp rate is active in that scenario, and not the PSw P/S ramp
rate.
