7.10 LL Logic
LL-low, low AL1-very low, AL2-low.
In this logic if “UP Scale” condition has been selected than in OPEN sensor
condition ALARM 1 and ALARM 2 will be in the NORMAL condition and will work
according to the following tables 7.4, 7.5, 7.6, 7.7.
If “DOWN Scale” Condition has
been selected for this logic than in OPEN sensor condition ALARM 1 and ALARM 2
will be in the ABNORMAL State of operation.

Table 7.1.
Note : If maximum value of zero and span then process value will display OVER/UNDER
message until value crosses 5% of selected group of mV(15mV or 30mV or 75mV). If
value of zero and span is less than maximum value of zero and span then process value
will display open message until value crosses 5% of selected group of mV (15mV or 30mV
or 75mV). Process value greater than5% of selected group of mV (15mV or 30mV or
75mV) then display will show OPEN message. Retransmission o/p will follow 5% of
display range and then it will give fixed o/p depending up on input OPEN sensor selection.
