Note on pushbuttons lock:
Access to main functions can be locked upon the position of the hardware lock jumper located in the front view of the
instrument head, behind the main cover, or by software activation (with ValVue software or a HART handled terminal).
When set to the secure position, shorting the two-pin header, no change of setting parameter is allowed (no access to Setup
and Clear Errors menus). It is not allowed to write any new data into the instrument memory. Pushbuttons, ValVue and any
HART
®
handheld are locked out, except to read data (normal, view data and view errors menus). In such case, LOCK
message is indicated on LCD display when user presses a button.
This hardware lock jumper must be set in the secure (locked) position to be used as a SIL 2 instrument.
