Operation
Shift Key Commands : Increment Field
When a quench detection has occurred, the Model 430 Programmer will
respond to no further input until the
RESET QUENCH
SHIFT-key is used,
or until the quench condition is cleared by a remote command. See Refer to
3.7.4
Increment Field SHIFT-key
The
INCR. FIELD
SHIFT-key is used to manually increase the field. This
is done at the defined ramp rate.
When the
INCR. FIELD
SHIFT-key is used, the current/field begins
ramping up. If the
INCR. FIELD
SHIFT-key is used again (while the
current/field is manually ramping up), the ramping will be paused.
Alternately, the
RAMP / PAUSE
key may be pressed to pause manual
ramping. Manual ramping will continue until paused or the
Current
Limit
1
or Magnet Current Rating is achieved.
3.7.5
Field <> Current SHIFT-key
The
FIELD <> CURRENT
SHIFT-key is used to toggle between the use of
field units, either kG (kilogauss) or T (tesla), and the use of current units
(A)
2
. If the Model 430 Programmer is using field units (either kG or T) and
the
FIELD <> CURRENT
SHIFT-key is used, the Model 430 Programmer
will begin using current units (A). Conversely, if the Model 430 is using
current units (A) and the
FIELD <> CURRENT
SHIFT-key is used, the
Model 430 will begin using field units (either kG or T).
Note
The Model 430 Programmer cannot use field units unless a valid
coil constant has been entered
3
.
3.7.6
Decrement Field SHIFT-key
The
DECR. FIELD
SHIFT-key is used to manually decrease the current/
field. This is done at the defined ramp rate.
When the
DECR. FIELD
SHIFT-key is used, the current/field begins
ramping down. If the
DECR. FIELD
SHIFT-key is used again (while the
current/field is manually ramping down), the ramping will be paused.
Alternately, the
RAMP / PAUSE
key may be pressed to pause manual
ramping. Manual ramping will continue until paused or the
Current
Limit
4
or Magnet Current Rating is achieved.
1. Refer to section 3.10.2.4 on page 56.
2. The value is always displayed in current (A) when an installed persistent switch is in
the
cooled state
since the value represents power supply current only, independent
of magnet current/field.
3. Refer to section 3.10.2.2 on page 54.
4. Refer to section 3.10.2.4 on page 56.
