Quench State Control and Queries
•
PSwitch?
Returns a “0” indicating the switch heater is OFF, or a “1” indicating the
persistent switch heater is ON.
•
PERSistent?
Returns the state of the "MAGNET IN PERSISTENT MODE" LED on the
front panel of the Model 430: ‘0” if the LED is OFF; “1” if the LED is ON.
4.5.8
Quench State Commands and Queries
The
QUench
commands control and query the quench state of the Model
430 Programmer. For further information regarding the quench detection
•
QUench {0|1}
Clears or sets the quenched state. Sending a “0” clears any quench
condition (equivalent to using the
RESET QUENCH
front panel SHIFT-
key). Sending a “1” sets a quench condition. Setting the quench state to “1”
is equivalent to a quench detection by the Model 430 Programmer — the
power supply output is forced to 0 V, the quench output of the rear panel
Quench I/O connector is asserted, and all ramping functions are disabled.
•
QUench?
Queries the quench state. If a “0” is returned, no quench condition exists.
If a “1” is returned, a quench detect has occurred and is still in effect.
•
QUench:COUNT?
Queries the number of recorded quench events.
4.5.9
Rampdown State Queries
•
RAMPDownFile?
Formats and sends the contents of the standard rampdown file as a
formatted ASCII text stream. This allows the user to view the state of both
the magnet and Model 430 Programmer during each recorded rampdown
event.
•
RAMPDownBackup?
Formats and sends the contents of the rampdown backup file as a
formatted ASCII text stream. When the number of recorded rampdown
events reaches 100, the standard rampdown file becomes the backup file,
and a new (empty) standard rampdown file is created. The standard
rampdown file contains data from the most recent rampdown events, and
the backup file (if it exists) contains data from the 100 rampdown events
preceding the oldest record in the standard rampdown file.
