Entry Description
UNITS LO xxxx –3000 to 30000
Note: Fixed at 0 when process input
linearization type is SQR ROOT.
OUTPUT LAST
FIXED
This is the output required during an input fault.
When an input failure is detected, controller is
put in manual and calculated output switches to
the fault output value.
FAULT OP xx 0 to 100%
If heat/cool is used, the output value (OV) can
be determined from heat output (HO) or cool
output (CO) and crossover value (CV) as
follows:
OV (Heat) = (((100-CV) × HO)/100) + CV
OV (Cool) = CV - ((CV × CO)/100)
LEVL PCT xx 0 to 100%
This is the percentage of input level used to
generate a fault condition and is calculated
using the configured input span.
For example, at the 10% level a fault in a 0 to 5
volt input (span is 5 volts) would trigger at
–0.01 (lower limit) and 5.5V and at the 20%
level it would trigger at –0.01 and 6.0V. At the
100% level, a 4 to 5V input with a span of 1V
would trigger a fault at 3 and 6V.
Limits on detection levels are:
Volt = –0.01 to 6.0V
millivolt = –10.00 to 130 mV
milliampere = –.20 to 55.00 mA
slidewire = –.1 to 1.200
RTD = –202 to 852°C, –332 to 1566°F
Thermocouple Type:
B = 370 to 1680°C, 698 to 3056°F
E = –210 to 1009°C, –346 to 1848°F
J = –210 to 1208°C, –346 to 2206°F
K = –210 to 1375°C, –346 to 2507°F
N = –10 to 1314°C, 14 to 2397°F
R = –30 to 1680°C, –22 to 3056°F
S = –30 to 1680°C, –22 to 3056°F
T = –210 to 410°C, –346 to 770°F
