Display window
The display window presents screens of information to the operator. Each screen of
information displays on the LCD that is back-lit and consists of four rows, each row being 20
characters long. Refer to Figure 10 for an illustration of the display window.
Each area of information on the screen is a field. Some fields are for display only and are not
changeable. However, fields that display a blinking cursor are data fields that the operator
can change to a new value.
The upper left-hand corner of each screen displays the current screen number that can range
from 000 to 999. Not all possible screen numbers are valid. If you enter an invalid screen
number, a “MENU DOES NOT EXIST” message displays.
The upper right-hand corner displays the Alarm signal. This displays as an “A”. This field
displays on every screen except password.
The cursor underlines its current location.
Each screen has display fields and sometimes data fields. The display fields are not
selectable or adjustable. Data fields enable the operator to enter data. Use
SELECT to move
to the beginning of a data field.
Security access level can effect whether you can enter data into a specific data field. For
example, alarms can be set at the supervisor security level but not at the operator security
level. If you attempt to enter an item that requires a higher security level, the “ACCESS
DENIED” message displays or the screen remains blank.
