Series DPC Duplexing Pump Controller

Series MPC Pump Controller

One or Two Pump Control with Built-In Alternation, Over Temperature Protection and Seal Failure Monitoring

The Series MPC Pump Controller provides versatile level control in a standard 1/4 DIN package. Designed for use with almost any style level transmitter the unit displays the present level and main set point value. Incorporated in the MPC is programmable level differential for on/off control of one or two pumps, valves, or other devices through two SPDT relays.

Features

  • Selectable pump alternation when used with two pumps to minimize pump wear. With alternation “on” a seal failure or over temperature condition will force the non-failed pump to lead status and stop alternation.
  • Alarms can be programmed for output indication of pump seal failure or over temperature.
  • Selectable time delay, for pump two, on power up to prevent both pumps from starting at the same time. If power is lost, upon regaining power a time delay of up to 60 seconds can be selected to prevent too large of a current draw.
  • In the event of power loss, upon regaining power a time delay of up to 60 seconds can be selected to prevent excessively large current draw
  • Test system function that simulates the process input to ensure the pumps are operating or to test programming.
  • User-friendly programming menu
