Q4-22
(0F04)
Water Level Decimal
Place Position
Water Lvl Dec Pt
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)
Default: 1
Range: 0 to 3

Q4-25
(0F07)
Water Level Control
Activation Level
WaterLvl Act Lvl
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
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.
Default: 0.0 ft.
Range: 0.0 to
1200.0

Water Level Control
Activation/
Deactivation Delay
WaterLvl Act Dly
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
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.
Default: 2 s
Range: 0 to
3600

<1> Resolution depends on parameter Q4-22, Water Level Decimal Place Position.
<2> Units are determined by Q4-15, Low Water Level Detection Time Unit, setting.

Suction Setpoint
Sets the amount of suction pressure to which the drive will
attempt to regulate.
Min.: 0.0
Max.: 1200.0
Q5-04
(0F23) Minimum Suction
Pressure
Min Suction Pres
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
all lag pumps.

Suction Pressure Sleep
Wake-Up Time
SP Wake-up Time
Sets the length of time for which the pressure must rise above
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.

Suction Pressure
Control Minimum
Speed
Suction Min Spd
Sets the minimum speed at which the drive will run when the
drive is controlling suction pressure.
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.
