Pushbutton Locks and Configuration-Lock Jumper

Before performing any configuration or calibration functions using the local display you must
first ensure that the pushbuttons are placed in unlocked mode using ValVue ESD. The
positioner is factory set in unlocked mode. See ValVue ESD On Line Help for more details.
The SVI II ESD offers several security levels. It may be desirable, after initial setup, to lock the
pushbuttons so that the SVI II ESD parameters cannot be inadvertently changed by buttons.
Several levels of software modifiable pushbutton locks are provided.
