Closed: Q1-03 or Q1-04 is PID Setpoint.
Function active in AUTO Mode during normal operation, also used with Pre-
Charge function. Function logic depends on P1-30, Low Water Digital Input
Configuration.
P1-30 = 0 (Normally open)
Closed: Low water level fault
Low Water Open: Reservoir/Tank is filled to normal level
P1-30 = 1 (Normally closed)
Closed: Reservoir/Tank is filled to normal level
Open: Low water level fault
Pre-Charge function: Function uses the low water level input as "Tank/Reservoir"
feedback to indicate that the water level has been reached.
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
High Water
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
Closed: Accumulated volume is reset to 0 and held at 0 if digital input remains

closed.
Closed: Prevents the drive from running when active for the time set in P4-26.
Must be inactive for the time set in P4-27 to allow the drive to run again.
Note:
Closed: Disables the secondary PI controller. Output behavior depends on the

setting of S3-12.
Closed: Enables the secondary PI controller. Output behavior depends on the
PI2 Disable N.C.
setting of S3-12 when open.
Closed: Changes the sign of the secondary PI controller input (reverse acting PI

control).
Closed: Resets the secondary PI controller integral value.

Closed: Locks the value of the secondary PI controller integral value.
PI2 Intgrl Hold
Description
Setting H1-oo = 88 and 89 simultaneously will trigger a "VLTS -
Volute-TStat Flt".
Setting H1-oo = 88 and 89 simultaneously will trigger a "VLTS -
Volute-TStat Flt".
Parameter P4-25 determines if this input is normally open or
normally closed.
