YES Start Learning the Process. After the
process has been learned the menu
item will revert to no.
no Learning will stay in present mode.
dFAC Damping factor, Select OFF, 1 to 7. Sets the ratio
of Rate to Reset for the SELF tunE mode. 7 =
most Rate. Factory set to 3. For a fast response
process the value should be lowered (less Rate).
For a slower process the value should be in-
creased (more Rate).
Pid Manually adjust the PID values. PID control consists of
three basic parameters, Proportional Band (Gain), Reset
Time (Integral), and Rate Time (Derivative).
#Pb1 (Option 948, 4-Stage Set Point) or
Pb1 Proportional Band (Bandwidth). Select 1 to 9999
°F, °C, or counts.
Pb2 Proportional Band (Bandwidth). Select 1 to 9999
°F, °C, or counts. Appears only if control is
equipped with second set point and Out2 is NOT
selected as ONOF.
#rES (Option 948, 4-Stage Set Point) or
rES Automatic Reset Time. Select OFF, 0.1 to 99.9
minutes. Select OFF to switch to OFS.
#OFS (Option 948, 4-Stage Set Point) or
OFS Manual Offset Correction Select OFF, 0.1 to 99.9%.
Select OFF to switch to rES.
#rtE (Option 948, 4-Stage Set Point) or
rtE Rate Time. Select OFF, 0.01 to 99.99 minutes,
Derivative.
SLO PID values are preset for a slow response process.
nor PID values are preset for a normal response process.
FASt PID values are preset for a fast response process.
Pid2 Linkage of PID parameters between SP1 and SP2: Select On or
OFF.
On
Applies SP1 rEs, rtE, Fbnd, and FrtE terms to SP2 for
heat/cool applications.
OFF SP2 functions without rEs, rtE, Fbnd and FrtE.
ArUP Anti- Reset Windup Feature: Select On or OFF.
On
When ArUP is On the accumulated Reset Offset value
will be cleared to 0% when the process input is not within
the Proportional Band.
OFF When ArUP is OFF, the accumulated Reset Offset
Value is retained in memory when the process input is
