Sets the full scale (20 mA) output of the pressure transducer that
is connected to the analog input terminal programmed for
Water Lvl Scale
"WaterLvl/Suction" (H3-oo = 23).
Note:
Sets the amount of water above the sensor to which the drive
will attempt to regulate.
Water Lvl Setpnt
Sets the level below which the amount of water must drop for
the time set in Q4-05 to put the drive to sleep.
Sets the length of time that the drive will delay after the water
level drops below the level set in Q4-04 before going to sleep.
WL Sleep Dly Tm
Sets the level above which the water needs to rise for more than
the time set in Q4-07 for the drive to wake up after being put to
sleep via parameter Q4-04, Minimum Water Level.
Sets the length of time that the water level set in Q4-06 must be
WL Wake-up Time met for the drive to wake up after being put to sleep via
parameter Q4-04, Minimum Water Level.
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.
Setting this parameter to 0.0 will disable the function.
Low Level Detect
Note:
Sets the length of time that the water level must fall below the
level set in Q4-09 to trigger the drive to respond. Applicable
Low Lvl Det Tm
when Q4-11 = 2 or 3.
Selects drive response when the water level drops below the
level set in Q4-09 for the time set in Q4-10.

0: No display (digital output only)
0: No Display
1: Alarm only
1: Alarm Only
2: Fault
2: Fault
3: Restart (time set by Q4-12)
3: Restart (Q4-12)
Note:
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

Description
1 PSI = 2.308 feet of water
Q4-10 detection time delay is only applicable
when Q4-11 = 2 or 3.
Q4-10 detection time delay is only applicable to
settings 2 and 3.
