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
