Operation
Setup Menu : Misc
the general user cannot execute those commands and/or modify
those settings. The implementation of settings protection in the
Model 430 Programmer is very flexible; it allows as many or as few
commands and/or settings to be locked as the magnet system
administrator desires. The magnet system administrator may lock
all but a few commands/settings, so that, for instance, the general
user has access to only the RAMP / PAUSE and RAMP TO ZERO
keys. Conversely, the administrator may lock, for instance, only the
Current Limit setting from use by the general user.
If an attempt is made to use a locked command or setting, the
Model 430 Programmer beeps twice; the command is not accepted
and the setting is not altered.
When ENTER is pressed to change settings protection, the
password must be correctly entered before settings protection can
be edited.
Using the keypad, type the numeric password (up to 4-digits) and
press ENTER . The default password is 1234. If an incorrect
password is entered, the Model 430 Programmer beeps and again
prompts for the password. Once the password has been correctly
entered, the protection value (Locked or Unlocked) can be edited for
each setting (see sections 3.10.3.6.1 through 3.10.3.6.25 below). The
default protection value for all settings is Unlocked.
Note
Once the password has been correctly entered, if no keys are pressed
for one minute, the Settings Protection submenu will be exited, and
the password must be entered again if further changes to settings
protection are desired.
If the correct password has been forgotten, contact AMI Technical
Support for assistance. To change the password, see
section 3.10.3.7 on page 71.
