*Selection here is used for both Loop 1 and Loop 2 if available. Also applies to Gain Scheduling on Loops 1 and 2.
NOTE 1: Does not apply to Three Position Step Control.
NOTE 2: If controller is in Manual upon failure, output will maintain its value at time of failure.
NOTE 3:These selections appear when:
1. Control Algorithm is selected for 3PSTEP.
2. Control Algorithm is selected for PD+MR and Output Algorithm is selected for Position Proportional.

Parameter
Definition
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:
PROPORTIONAL BAND selects units of percent
proportional band for the P term of the PID algorithm.
Where: PB % = 100 % FS
GAIN selects the unitless term of gain for the P term of the
PID algorithm.
Where: GAIN = 100 % FS
RESET UNITS—Selects units of minutes per repeat or
repeats per minute for the I term of the PID algorithm.
20 Repeats per Minute = 0.05 Minutes per Repeat.
REPEATS PER MINUTE—The number of times per
minute that the proportional action is repeated by reset.
MINUTES PER REPEAT—The time between each repeat
of the proportional action by reset.
