Sets the number of decimal places for the Water Level
parameters and monitor:
0: No Dec (XXXXX)

1: 1 Dec (XXXX.X)
2: 2 Dec (XXX.XX)
3: 3 Dec (XX.XXX)
When the amount of water above the sensor drops below this
level for more than the Q4-26 time, Water Level Control is
activated allowing it to affect the output frequency. When the
WaterLvl Act Lvl amount of water below the sensor rises above this level for more
than the Q4-26 time, Water Level Control is deactivated causing
it to have no effect on the output frequency.
Water Level Control is always active (if enabled) when set to 0.
When the amount of water above the sensor drops below the
Q4-25 level for more than this time, Water Level Control is
activated allowing it to affect the output frequency. When the
WaterLvl Act Dly
amount of water below the sensor rises above the Q4-25 level
for more than this time, Water Level Control is deactivated
causing it to have no effect on the output frequency.

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
all lag pumps.
Sets the length of time that the drive will delay after suction
pressure drops below the level set in Q5-04 before going to
SP Sleep Dly Tm
sleep.
Sets the level above which the suction pressure must rise for the
Wake-Up Pres time set in Q5-07 for the drive to wake up when it has been put
to sleep via parameter Q5-04, Minimum Suction Pressure.
Sets the length of time for which the pressure must rise above
SP Wake-up Time the level set in Q5-06 to wake up the drive when it has been put
to sleep via parameter Q5-04, Minimum Suction Pressure.
Sets the minimum speed at which the drive will run when the
drive is controlling suction pressure.
Suction Min Spd When the drive is controlling outlet pressure or this parameter
is set lower than P1-06 and P4-12, parameters P1-06 and P4-12
will be used as the minimum speed.
