Operation
There are five basic keypad operations: direct operation, menu navigation, number
entry, alpha-numeric entry and setting selection.
D Direct Operation: the key function occurs as soon as you press the key; these
include the Setpoint, P, I, D, Manual Out, and All Off keys.
D Menu Navigation: each menu has a list of configurable parameters. Menus that
apply to multiple entities (for example, Input Setup could apply to Input A, B, C, or
D) have a first level selection to determine which entity to configure (for instance,
Input C). Once the first level selection is made, the list of menu parameters is dis-
played. The parameter labels are displayed on the left, and the current value of
each parameter is displayed on the right. In this screen, use the and keys to
move the highlight up or down, respectively. Press Enter to enter the setting
mode for the highlighted parameter. The type of setting mode depends on the
type of parameter highlighted. The possible setting modes are: Number Entry,
Alpha-Numeric Entry, and Setting Selection. Refer to the respective entry mode
descriptions below. During menu navigation, press Escape (Exit Menu) to per-
form the Exit Menu function; this will not cancel any setting changes.
D Number Entry: allows you to enter number data using the number pad keys. Num-
ber pad keys include the numbers 0–9, +/-, and the decimal point. The propor-
tional control parameter is an example of a parameter that requires number
entry. During a number entry sequence use the number entry keys to enter the
number value, press Enter to accept the new data. Press Escape once to clear the
entry, and twice to return to the Menu Navigation mode.
D Alpha-Numeric Entry: allows you to enter character data using the number pad
keys, and the andkeys. The input sensor name is an example of a parameter
that requires Alpha-Numeric Entry. Press or to cycle through the upper and
lower case English alphabet, numerals 0 through 9, and a small selection of com-
mon symbols. Press Enter to advance the cursor to the next position, or to save
the string and return from Alpha-Numeric Entry mode if in the last position. Press
Escape to move the cursor back one position, or to cancel all changes and return
from Alpha-Numeric Entry mode if at the first position. Press any of the number
pad keys, except for +/-, to enter that character into the string and advance the
cursor to the next position automatically, or to save the string and return to
Menu Navigation mode if in the last position. Use the +/- key to enter the
whitespace character.
