and then the
PERSIST. SWITCH
CONTROL
key to turn on the persistent switch heater
current. Note that the Model 430 Programmer will enter the
HEATING SWITCH mode and disallow any ramping during
the switch heating period.
3. At the end of the switch heating period, the
MAGNET IN

430 Programmer will be in the PAUSED mode.
3.14 Ramping Functions Example
As an example of ramping to two target field/current settings, refer to
Figure 3-14 below. Each step is labeled as 1 through 8 in Figure 3-14. The
Model 430 Programmer, for the purposes of the example, is assumed to be
in the PAUSED mode at 0 A at the beginning of the ramping example.
Point 1
. The current is 0 A and the Model 430 Programmer is in the
PAUSED mode. The user sets the target field/current to 13.000 A. The
RAMP / PAUSE
key is pressed so that the PAUSED mode is no longer
active and the Model 430 begins ramping current.
Point 2
. The target field/current setting of 13.000 A is achieved and the
Model 430 Programmer switches to HOLDING mode.
Point 3
. The user changes the ramp rate setting. The user also sets a new
value of +40.000 A for the target field/current. As soon as the new target
field/current is entered, the Model 430 Programmer automatically begins
ramping at the specified ramp rate.
