7 Suction Control via Constant Pressure w/Well Draw Down
YASKAWA TM.iQp.10 iQpump Technical Manual Supplement 19
Multi-function Output Setting H2-††: Low Suction (New)
„ Related Parameters
When P1-01 = 3 (Memobus Multiplex), the Water Level or Suction Pressure can be transmitted or read through the
network.
Refer to Water Level/Suction Pressure Control in Memobus Multiplex on page 26 .
P9-50 Water Level Source (P8-01 set to 0 or 1, Water Level Control)
Defines which signal to use for Water Level Control (P8-††) when P1-01=3.
Setting has no effect when P1-01 ≠3.
P9-50 Suction Pressure Level Source (P8-01 set to 2 Suction Control)
Defines which signal to use for Suction Pressure Control (P8-††) when P1-01=3.
Setting has no effect when P1-01 ≠3.
Setting Description
58 Low Suction
This output will energize if P8-01 = 2 and the suction pressure drops below the Low Suction Pressure
Detection Level (P8-07) for more than the Low Suction Pressure Delay Time (P8-08), or if there is a
LOSUC - Low Suction Pressure Fault.
