Parameter Definition
DEADBAND
DEADBAND is an adjustable gap between the operating ranges of
output 1 and output 2 in which neither output operates (positive
value) or both outputs operate (negative value).
–5.0 to 25.0 %
0.0 to 25.0 %
0.5 to 5.0 %
Time Duplex
On-Off Duplex
Position Proportional and Three Position Step
OUT HYST
0.0 to 100.0 % 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.
FAILMODE
NoLATCH
FAILSAFE MODE
NON LATCHING—Controller stays in last mode that was being
used (automatic or manual); If unit was in Automatic mode, then
the output goes to the failsafe value. (NOTE 1, NOTE 2)
LATCH
LATCHING—Controller goes to manual mode; If unit was in
Automatic mode, then the output goes to the failsafe value. (NOTE
2)
FAILSAFE
0 to 100 %
FAILSAFE OUTPUT VALUE—The value used here will also be
the output level when you have Communications SHED set to
failsafe or when NO BURNOUT is configured and Input 1 fails.
ATTENTION Applies for all output types except Three Position
Step Control.
0 PCT
100 PCT
THREE POSITION STEP FAILSAFE OUTPUT
0 PCT—Motor goes to closed position.
100 PCT—Motor goes to open position.
SW FAIL
0 PCT
100 PCT
Position Proportional motor position when slidewire fails.
0 PCT—Motor goes to closed position.
100 PCT—Motor goes to open position.
ATTENTION PWR OUT must be configured for FSAFE.
MAN OUT
0 to 100 %
POWER-UP PRESET MANUAL OUTPUT—At power-up, the
controller will go to manual and the output to the value set here.
(NOTE 1)
AUTO OUT
0 to 100 %
POWER-UP PRESET AUTOMATIC OUTPUT—At power-up, the
controller will begin its automatic control at the output value set
here. (NOTE 1)
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
