    CTX switches are equipped with the MX-60 control panel as standard.
    This microprocessor control includes:
  • Undervoltage sensing (90% pickup/80% dropout of the utility source
    • Voltage and frequency sensing of the generator source (90% voltage/95% frequency pickup)
    • Time Delay Engine Start – 5 seconds (P)
    • Time Delay Engine Warmup – Transfer to Generator – 20 seconds (W)
    • Time Delay Utility Stabilization/Retransfer to Utility – 5 minutes (T)
    • Time Delay Engine Cool Down – 5 minutes (U)

    All time delays are fixed.
