EMS-RV Energy Management Soft Starter

Retaining the incredible features from the original EMS, such as Power metering & Modbus RTU communications, the EMS-RV has the added benefit of reduced voltage starting. Reducing the inrush current further increases energy savings and extends equipment life.

Overview


Features & Benefits

  • Soft Start
    • Energy savings through reduced inrush current
    • Adjustable current limit, initial voltage, start/stop time
    • Coast to stop
    • Torque boost
    • SCR over-temperature detection
    • Shorted SCR detection
    • Across-the-line start for emergency situations
  • Superior motor protection
    • Class 5-30 Electronic Overload
    • Phase loss/unbalance protection
    • Stall/locked rotor condition
    • Cycle fault
    • Underpower (Protects the motor in a belt loss condition)
  • Built-in power monitoring, fault logging and communications
    • 1% ANSI grade metering
    • kW and kWh data available on LCD display
    • Last 15 fault types are recorded (e.g. underpower, overload, voltage/current loss/unbalance, etc.)
    • Fault counter: stores how many times each fault type has occurred (Up to 255)
    • Logs changes to parameter settings (e.g. overload, OV/UV, underpower)
    • All power condition values are displayed
    • Built-in RS-485 for Modbus RTU communication
  • HOA keypad with LCD display
    • Plain English operation – easy to set up and simple to operate
    • LEDs indicate Hand/Off/Auto modes, run and fault conditions
  • Building automation system ready
    • Relay outputs for fault and proof of flow verification
    • Detects belt loss and alerts automation system
    • Eliminates costly current sensors
    • Voltage inputs for auto run and fireman’s override (accepts 12-120VAC/DC)
    • Wire directly from the automation system to the starter, no interposing relays necessary
    • Fireman’s override initiates smoke purge sequence during emergency situations for safety and code compliance
    • Dry inputs for auto run, emergency shutdown, and permissive auto (N.O. dry contact closure)
    • Analog input for (selectable) 0-10V, 4-20mA, 10k Thermistor, viewable as a Modbus point
  • Optional circuit breaker disconnect
    • Molded case circuit breaker provides branch and short circuit protection
    • High interrupting ratings for maximum electrical system compatibility
    • No fuses required – save time and money
    • Lockable handle for safety
  • Multi-tap control power transformer (CPT)
    • Multi-tap CPT input accepts all common motor voltages
    • Integrated secondary protection – no fuses required
