Function active when the drive is running. Function logic depends on P1-31, High
Water Digital Input Configuration.
P1-31 = 0 (Normally open)
Closed: High water level fault
Open: Reservoir/Tank is filled to normal level
P1-31 = 1 (Normally closed)
Closed: Reservoir/Tank is filled to normal level
Open: High water level fault
