SVI II AP Instruction Manual
To determine how to display and select a specific parameter value or configuration option,
refer to the menu structure diagrams shown in Figure 52 on page 75 through Figure 55
on page 82. When using these diagrams as a map you can move through the menus to
the function you needed.
NOTE
If the pushbuttons are pushed after being locked by ValVue
software, the message LOCKED appears. Refer to the
ValVue User’s Guide for instruction about unlocking the
pushbuttons.
Pushbutton Locks and Configuration-Lock Jumper
Before performing any of these functions with the local display you must first ensure that
the pushbuttons are placed in the unlocked mode using ValVue Lite. The positioner ships
in the unlocked mode. See ValVue documentation for more details.
The SVI II AP offers several levels of plant security. It may be desirable, after initial setup,
to lock the pushbuttons so that the SVI II AP parameters cannot be inadvertently changed
by the buttons. Several levels of software modifiable pushbutton locks are provided.

Access
Allow Local Buttons: Buttons on the SVI II AP are fully enabled.
Lock Out Local Calibration and Configuration: Use the buttons to perform operations in
normal operating mode and manual mode. Do not go to configure or calibrate mode.
Lock Out Local Manual: Examine variables in normal operating mode but do not put the
valve in manual operating mode. Access to calibrate or configure modes is not available.
Security Level 0 Lock Out All Buttons: The buttons are disabled (level 0).
Hardware Configuration Lock
Additional security is achieved using the hardware configuration-lock jumper shown in
Figure 50 on page 66. When set to secure position, shorting the two-pin header,
configuration and calibration are not permitted by the local interface or by remote
communications. Pushbuttons, ValVue and GE's DPI620 are locked out, except to
examine configuration, calibration, and position. This is similar to Security Level 1 shown
in the Pushbutton Lock Security Level table.
The following pages display the menu structure for operating the SVI II AP using local
pushbuttons.
