Mercoid MPC Level Controller

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
• When used with a submersible pump including a moisture sensor the MPC has alarm light indication of seal failure
• When used with a pump including a thermostat the MPC has alarm light indication of pump over temperature and removes the pump from service. The pump can be brought back into service automatically or by manual reset when the pump has cooled down.
• 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
• Integral 24 VDC power supply for level transmitter
• Displays pump run time from a front panel button
• Test System function that simulates the process input to ensure the pumps are operating or to test programming
• User selectable security lock-out of programming and/or set points
• Inputs: 4 (or 0) to 20 mA DC or 2 (or 0) to 10 VDC selectable
