Parameter Definition

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).

Time Duplex

On-Off Duplex

Position Proportional and Three Position Step

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.

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 Input 1 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—Atpower-up, the controller will go to manual and the output to the value set here. (NOTE 1)

POWER-UP PRESET AUTOMATIC OUTPUT—Atpower-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:

PROPORTIONAL BAND selects units of percent proportional band for the P term of the PID algorithm.

Where: PB % = 100 % FS GAIN

GAIN selects the unitless term of gain for the P term of the PID algorithm.

Where: GAIN = 100 % FS PB%
