        • Off
      • Standard Components
        • Managed switch that offers configurable site communication and enhanced security provision to assure network integrity. One ethernet (4-Wire) port connection for customer networking of DER's.
        • Telematics PLE702 (See LEHE22212) allows data logging of 300 channels for 1.5 days (requires subscription for visualization).
        • Best Battery Diode (BBD) for backup power supply.
      • Control Modes | Auto | Grid Connected - Sub-modes (16):
        • Scheduling - 5 schedules and 6 segments - BESS dispatch scheduling based on year, month, time, day and segment of day - 5 schedules and 6 segments - Import and export scheduling for active and reactive power based on time, day and segment of day
        • Load sense/load demand - Based on asset priority or engine-hour balancing - Automatically matches on-line asset capacity to the loads
        • Load smoothing mode - Non-stable load dispatch using available assets for specified durations of time
        • Reliability mode - At least one high priority "fuel consuming" asset ON
        • Grid Reactive Control mode - There are 4 available reactive power control settings - Constant VAr, Constant PF, Volt-VAr curve, Watt-VAr curve.
        • Pro-active add and drop - Ability to manually bring additional gensets online in anticipation of bringing on large loads. - Manually turning off gensets instead of waiting for LSLD drop when the customer knows large loads are being taken offline
        • Utility parallel, base load operations
        • 3 Flexible efficiency modes 1, 2 and 3 that may be set up based on asset group priorities
        • Economy mode - All Gensets and non-renewable "fuel consuming" assets OFF
        • Unplanned Islanding or Emergency standby - Closed transition (with soft unload) or Open transition
        • Utility parallel, import power from grid - Minimum import kW setpoint is maintained
        • Planned Islanding or Intentional islanding
        • Load shed/load add - Automatic or manual load shed up to eight (8) stages
        • Utility parallel, export power to grid -Target export setpoint is maintained
      • Input/Output Ethernet Modules
        • Package mounted and/or ship loose options (See LEHE22466).
        • Supports expanded Inputs/Outputs (IO) capability of the Cat ECS 400 control: - Analog & digital I/O - Temperature sensing (RTD).
        • Interface with a single ATS and other relays that allows load shed/load add with up to eight (8) load breakers.
        • Configure I/O for any event (read & write function).
      • Control Modes | Auto | Off-Grid (Island) - Sub-modes (7):
        • Pro-active add and drop - Ability to manually bring additional gensets online in anticipation of bringing on large loads - Manually turning off gensets instead of waiting for LSLD drop when the customer knows large loads are being taken offline
