No LED will blink
OR

of total range
0 to 5V

0 to 10V
PV LOW
No LED will blink
OR
„ON‟ if PV value is greater or equal to 1 %
of total range
Note:
If set PV_low/PV_high for input type is less then maximum value of zero and span, then
process value will display readings upto Over / Under % range( Over and Under % range is user
settable) of display range(User set PV_High / PV_Low), then after it will show
oVER
/
UnDR
(OVER/UNDER) message until value crosses maximum value of Sensor range.
Note that
, for “over”
message, 1 to 100 LEDs of bar display will blink and 101
st
LED will be “OFF”. For “under” message, 1
to 100 LEDs of bar display will be “OFF” and 101
st
LED will be “ON”. If process value is greater than
maximum value of zero/span then display will show
oPEn
(OPEN) message.
Note that,
for PV
readings below PV Low value and upto minimum possible range of zero, bar display will behave same
as of
“under” reading. And for PV readings above PV High value and upto maximum possible range of
span, bar display will behave same as of “over” reading. Retransmission o/p (Optional) will follow
Over / Under % range of display range. When PV value shows Over /Under message , retransmission
o/p holds the same value of the last state which was occurred before Over / Under condition . When
the process value is OPEN then retransmission o/p will be depends upon OPEN sensor selection . In
case of linear inputs scaling is applied then during OPEN sensor condition it may not show
oPEn
(OPEN) message , instead it will show either
oVER
/
UnDR
(OVER/UNDER).
