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
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
Only applicable for ON/OFF control.
FAILSAFE MODE

ATTENTION Applies for all output types except Three Position
Step Control.

ATTENTION PWR OUT must be configured for FSAFE.
PROPORTIONAL BAND
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%
