3.16.2 External
Rampdown
while not in Persistent Mode
When external rampdown is initiated with the magnet
not
in
PERSISTENT mode, the persistent switch is either off or not installed so
there is no need for persistent switch heating. The power supply is already
at (and in control of) the magnet current, so the Model 430 Programmer
executes an ordinary rampdown:
1. The rampdown begins immediately at the ZEROING CURRENT
mode described on page 93 (step 4 of section 3.16.1, “External
Rampdown while in Persistent Mode”):
2. The sequence continues as described for the magnet in persistent
mode (section 3.16.1, steps 5 through 6).
Note
After rampdown, the external rampdown signal MUST be cleared
before continuing. Further operator control is inhibited until the
external rampdown signal is cleared.
3.17 Summary of Operational Limits and Default Settings
Table 3-7 provides a summary of the operational limits and the default
setting for all Model 430 Programmer parameters. If the user attempts to
enter a value outside of the limits, the Model 430 Programmer will beep
once and revert to the previous setting.
References to the specifications indicate that the absolute limit is
determined by the specific configuration of the Model 430 Programmer
purchased.
