Setup Lists
You will not see every parameter listed here. These vary depending on the features enabled on your device.
Input Error Power What the controller outputs will do when an
input error switches control to manual mode.
Off, sets output power to
0% (62)
Bumpless transfer, main-
tains same output power,
if it was less than 75% and
stable, otherwise 0% (14)
Fixed Power, sets output
power to Fixed Power set-
ting (54)
User, sets output power to
last open-loop set point the
user entered (100)
User 7013
Fixed Power Manual output power level that will take effect
if an input error failure occurs while User Fail-
ure Action is set to Fixed Power.
Set Point Open Loop Limit

0.0 7011
OpLoop Detect Enable Open Loop Detect Enable. Select Yes to de-
tect conditions that prevent the process from
changing in specified time frame by a specified
amount when PID power is at 100%. An open
loop detect error will disable the control loop.
No (59)
Yes (106)
No 8039
OpLoop Detect Time Open Loop Detect Time. Process must deviate
by the Open Loop Detect Deviation value in the
specified time, while at 100% PID power, oth-
erwise an Open Loop Detect event is triggered.
0 to 3,600 seconds 240 8040
OpLoop Detect Dev Open Loop Detect Deviation. Process must
deviate by this value in the Open Loop Detect
Time while at 100% PID power to prevent an
open loop error.
