Parameter
Definition
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.
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)
LATCHING—Controller goes to manual mode; If unit
was in Automatic mode, then the output goes to the
failsafe value. (NOTE 2)
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 the PV Source fails.
ATTENTION Applies for all output types except
Three Position Step Control.
THREE POSITION STEP FAILSAFE OUTPUT
0 PCT—Motor goes to closed position.
100 PCT—Motor goes to open position.
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.
POWER-UP PRESET MANUAL OUTPUT—At
power-up, the controller will go to manual and the
output to the value set here. (NOTE 1)
POWER-UP PRESET AUTOMATIC OUTPUT—At
power-up, the controller will begin its automatic
control at the output value set here. (NOTE 1)
PROPORTIONAL BAND UNITS—Select one of the
following for the Proportional (P) term of the PID
algorithm:
