Inputs, Outputs, Timers, and Other Control Logic
Rotating Default Display (Only on Models With LCD)
When IN101 = 0, the following will display on the front-panel display
(assuming 51NP= 180 A primary, and 51QP = OFF):
If the pre-label is longer than six characters, the string is processed as if there
were only six pre-characters.
To illustrate this, continuing from the above example:
SET T
DP1_0 = NEUTRP=;;51NP;A
with IN101 deasserted, will display:
The addition of the = sign caused the number of pre-characters to exceed six,
so the processing logic stops there, and will display the first six characters
followed by the setting values. The post character(s), A in this case, are
ignored.
Examples With ;;;xxx; Control Strings:
Use the ;;; control string to decrease the display resolution, and make more
characters available for labeling purposes. Use the table above to determine
the appropriate numerical setting variable. The following setting example
allows 9 characters of label text:
SET L
DP1 = IN101
SET L
DP2 = IN101
SET T
DP1_0 = 51THXYZ=;;;000;A
The pre-label characters are: 5, 1, T, H, X, Y, Z, =. The post-label character is
A. The total number of label characters is 9.)
SET T
DP2_0 = 51ABCD=;;;001;AP
When IN101 = 0, the following will display on the front-panel display
(assuming 51AP = 720 A primary, and 51BP = 600 A primary):
PTO= 720.00AP
GND PU 121.20
NEUTRP 180.00
N SEQ= OFF
NEUTRP 180.00
N SEQ= OFF
51THXYZ= 720A
51ABCD= 600AP
