The Local Operator Interface (LOI), shown in Figure 6-3, utilizes a bright blue
gas-fluorescent display. Intensity is adjustable. There is an Infrared LED
source and a detector for each key. The detectors can detect a finger placed
above the button through the glass window. There is no need to open the
instrument in bad weather in order to access the electronics.
The Local Operator Interface (LOI) has a lockout feature that prevents nui-
sance actuation by someone brushing against the glass window, raindrops,
dirt, insects, etc. This lockout mode is automatically established when no but-
tons are pushed for 30 seconds (default). This countdown to lockout is con-
figurable.
In order to unlock the display, input a "Z" pattern. First, push the top left (gray)
arrow, then the top right, followed by the bottom left and finally the bottom
right. The "LK" notation in the upper right corner of the display will now dis-
appear. Push the gray arrow at the top left hand corner once more to enter
into the menu structure. Once one moves deeper into the menu structure,
additional time is provided to the user so that the lockout initiation does not
become a nuisance. This additional "revert" time is defaulted at one hour and
is also user configurable.
