Pushbutton Locks And Configuration-Lock Jumper; Hardware Configuration Lock - GE Baker Hughes Masoneilan SVI FF Installation And Operation Manual

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. The positioner ships in the
unlocked mode.
The SVI FF offers several levels of plant security. It may be desirable, after initial setup, to lock
the pushbuttons so that the SVI FF parameters cannot be inadvertently changed by the
buttons. Several levels of software modifiable pushbutton locks are provided.
Level
Allow Local Buttons
Lock Out Local Calibration and
Configuration
Lock Out Local Manual
Lock Out All Buttons

Hardware Configuration Lock

Additional security is achieved using the hardware configuration-lock jumper shown in
Figure 33 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 a handheld are locked out, except to examine configuration,
calibration, and position. This is similar to Security Level 1 shown in Table 28.
