OUT HYST
0.0 to 5.0% of PV Span
HYSTERESIS (OUTPUT RELAY) is an adjustable
overlap of the ON/OFF states of each control output.
This is the difference between the value of the
process variable at which the control outputs
energize and the value at which they de-energize.
Only applicable for ON/OFF control.
FAIL MODE
NON LATCH
LATCHING
FAILSAFE MODE
NON LATCH - when the controller has gone to
failsafe and the problem is corrected, the controller
will go to automatic mode on power up at the
setpoint that was being used.
LATCHING - When the controller has gone to
failsafe and the problem is corrected, the controller
will stay in manual mode.
FAILSAFE
0 to 100%
FAILSAFE OUTPUT VALUE — The value used
here will also be the output level when you have
Communications SHED or when NO BURNOUT is
configured and Input 1 fails.
PBorGAIN*
PROPORTIONAL BAND UNITS — Select one of
the following for the Proportional (P) term of the PID
algorithm:
PB PCT
PROPORTIONAL BAND — Selects units of percent
proportional band for the P term of the PID
algorithm.
Where: PB% = 100%FS
GAIN
GAIN
GAIN selects the unitless term of gain for the P term
of the PID algorithm.
Where: GAIN =100%FS
PB%
MINorRPM*
RESET UNITS — Selects units of minutes or repeat
per minutes for the I term of the PID algorithm. 20
Repeats per Minute = 0.05 Minutes per Repeat.
RPM
REPEATS PER MINUTE — The number of times
per minute that the proportional action is repeated by
reset.
MINUTES
MINUTES PER REPEAT — The time between each
repeat of the proportional action by reset.
*Selection here is used for both Loop 1 and Loop 2 if available. Also applies to Gain Scheduling on Loops 1 and 2.
