MPC What is it?

• ¼ DIN Control for one or two pump systems
• Takes a level transmitter current input
• Has simple programmable on and off points for
  pump control

3
Application

• What is a Lift Station
• Lift stations transport sewage to the treatment
  facility
• Or serve as a point of collection for a complex,
  building, etc.

MPC Key Feature

• Pump Seal Failure
• Submersible pumps contain a conductivity moisture
  sensor to detect outer seal failure which the MPC
  monitors
• MPC has alarm light indication of failure
• Programmable to either leave the pump in service
  or force the pump to lag use only for a two pump
  system

Temperature sensor
14
MPC Key Feature

• Pump Over Temperature Monitor
• MPC receives this input and takes the pump out of
  service if the pump over heats
• For a two pump system the good pump is forced to
  being the lead pump if alternation is on
• MPC has alarm light indication of failure
• Programmable for automatic or manual reset

15
Applications Control Panels

• Using the MPC as a component of the pump control
  panel
• Reduces components
• Adds extra features

MPC Key Feature

• Pump Alternation
• Selectable for lead/lag operation
• Alternates pumps between lead and lag operation
  to evenly wear both pumps
• Extends pump life
