When the suction pressure drops below this level for more than
the Q5-26 time, Suction Pressure Control is activated allowing
it to affect the output frequency. When the suction pressure rises
above this level for more than the Q5-26 time, Suction Pressure
SucPress Act Lvl
is deactivated causing it to have no effect on the output
frequency.
Suction Pressure Control is always active (if enabled) when set
to 0.
When the suction pressure drops below the Q5-25 level for more
than this time, Suction Pressure Control is activated allowing it
to affect the output frequency. When the suction pressure rises
SucPress Act Dly
above the Q5-25 level for more than this time, Suction Pressure
Control is deactivated causing it to have no effect on the output
frequency.

Sets the full scale (10 V or 20 mA) output of the pressure
PI Aux Lvl Scale transducer connected to the analog input terminal programmed
for "PI Aux FB Level" (H3-oo = 27).
Sets the level to which the drive will attempt to regulate.
PI Aux Setpoint
Sets the level below which the drive must fall for longer than
the time set in Q6-05 time before the drive goes to sleep and
PI Aux Min Lvl
turns off all lag pumps.
Note:
Inverse Acting (Q6-23 = 1): Sets the amount of time that the
drive will delay before going to sleep after the level drops below
Q6-04 setting.
Sleep Dly Time
Normal Acting (Q6-23 = 0): Sets the amount of time that the
drive will delay before going to sleep after the level rises above
