Greenheck says its new, fully programmable energy-management motor starter, Model MSEM, can be specifically adapted to the user’s needs. Available for single-phase or three-phase commercial or industrial applications, MSEM features a hands-free auto keypad with LCD display to easily adjust settings. It offers five different control inputs including two separate auto-run inputs, permissive input, emergency shutdown and fireman’s override; two status outputs; under/over voltage and power protection; and electronic overload for real-time current monitoring for motor protection.

Model MSEM also has a limit switch input to ensure that the fan does not start until the damper is fully opened. Options include ground fault protection and time delays, as well as one of four optional boards: power monitoring board, BACnet communications board, Modbus communications board or Ethernet I/O (fault logging) board.
