Setting 8C: Disable Pre-Charge
Close to disable pre-charge.
Settings 8D and 8E: Multi Setpoints 1 and 2
Settings 8D and 8E will override all other PID setpoints when closed.

Setting 8F: Low Water Level
Function is active in AUTO Mode during normal operation and is also used with Pre-charge function.
Function depends on P1-30, Low Water Digital Input Configuration, setting.
When P1-30 = 0 (N.O.): Closed: Low Water Level Fault. Open: Reservoir/Tank is filled to normal level.
When P1-30 = 1 (N.C.): Closed: Reservoir/Tank is filled to normal level. Open: Low Water Level Fault.
Pre-charge function uses low water level input as "Tank/Reservoir" feedback to indicate water level reached.
Setting 90: High Water Level
Function is active when the drive is running and depends on P1-31, High Water Digital Input Configuration, setting.
When P1-31 = 0 (N.O.): Closed: High Water Level Fault. Open: Reservoir/Tank is filled to normal level.
When P1-30 = 1 (N.C.): Closed: Reservoir/Tank is filled to normal level. Open: High Water Level Fault.
Setting 95: Remove Drive Disable
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:
Parameter P4-25 determines whether this input is Normally Open or Normally Closed.
Setting B0: Emergency Override Function
The Emergency Override function is activated by closing the digital input programmed for Emergency Override Forward Run
(H1-oo = AF) or Emergency Override Reverse Run (H1-oo = B0).
If H1-oo = 6A (Drive Enable) is programmed, it must be opened to disable the drive for Emergency Override to take effect.
Closing both Emergency Override digital inputs at the same time will trigger an External Fault (EF) error.
When the drive is in Emergency Override, the frequency reference source is dependent on parameter S6-02, Emergency
Override Reference Selection. When S6-02 is set to 0 (Use S6-01 Reference), the drive will run at the S6-01 setting. When
S6-02 is set to 1 (Use Frequency Ref), the drive will use the currently selected frequency reference (based on b1-01 and HAND/
AUTO) as the run speed.
An alarm will flash during Emergency Override indicating that the function is active and the direction the drive is commanded
to run.
Resettable faults occurring when Emergency Override is activated will be cleared.
The drive will perform unlimited speed search retries during Emergency Override.
When Emergency Stop is active and Emergency Override is activated, the drive will run in Emergency Override mode.
The CALL (Serial Communication Error) mechanism is deactivated when Emergency Override is activated.
The Emergency Override function has priority over the PID Sleep feature (b5-15/b5-16).
Setting AF: Emergency Override Forward Run
Enables Emergency Override Forward Run (Enabled when S6-01 = 1).
Setting B0: Emergency Override Reverse Run
Enables Emergency Override Reverse Run (Enabled when S6-01 = 1).
