Sets the minimum speed at which the drive will run when the
drive is controlling the water level.
Level Min Spd When the drive is controlling pressure or if this parameter is set
less than P1-06 and P4-12, parameters P1-06 and P4-12 will be
used as the minimum speed.
Sets the level below which the water level must drop for the time
set in Q4-10 to trigger the drive response set in Q4-11.
Low Level Detect
Setting this parameter to 0.0 will disable the function.
Sets the length of time that the water level must fall below the
level set in Q4-09 to trigger the drive response set in Q4-11.
Low Lvl Det Tm
Selects drive response when the water level drops below the
Low Lvl Behavior
level set in Q4-09 for the time set in Q4-10.
0: No Display
0: No display (digital output only)
1: Alarm Only
1: Alarm only
2: Fault
2: Fault
3: Restart (Q4-12)
3: Restart (time set by Q4-12)
Sets the length of time that the drive will wait before attempting
an auto-restart of the Low Water Level fault.
WtrLvl Restart
This parameter is effective only when Q4-11 is set to 3 and
L5-01 is set to a value greater than 0.
Sets the proportional gain for the water level control.
Lvl Ctrl P Gain
Sets the integral time for the water level control.
Setting this parameter to 0.0 disables the water level control

Sets the full scale (20 mA) output of the pressure transducer that
Suction Scaling is connected to the analog input terminal programmed for
"WaterLvl/Suction" (H3-0o = 23).
Sets the amount of suction pressure to which the drive will
attempt to regulate.
Suction Setpoint
Sets the level below which the suction pressure must fall for
longer than the Q5-05 time to put the drive to sleep and turn off
Min Suction Pres
