; *************** TRIP CHANNEL #32 ****************
; PRECAT RIGHT BANK VALVE SENSE LOW FAULT ********
; Fault on bad LOW Valve sense.
; TRIP ENABLE *************************************
; Select minimum controlled valve opening setpoint.
;
; When controller outputs valve opening % above this
; setpoint, LOW VALVE SENSE TRIP is ENABLED; below
; this setpoint, TRIP is DISABLED.
;
; Thus, a LOW VALVE SENSE TRIP is recognized when
; the controller outputs a valve opening greater
; than the setpoint but a valve low current condition
; is detected; the TRIP is ignored when the controller
; intentionally outputs a low valve opening.
;
; Examples:
;
; 1) Controller @ Startup outputs 10% valve opening
; --> LOW VALVE SENSE TRIP DISABLED b/c controller
; valve output of 10% is less than 35% setpoint
;
; 2) Controller @ Run outputs 55% valve opening
; --> LOW VALVE SENSE TRIP ENABLED b/c controller
; valve output of 55% is greater than setpoint
; If valve low current condition detected,
; LOW VALVE SENSE TRIP is recognized
;
; Min Val Max Val
; 0 -> 35 (default) -> 100 (in valve opening %)
