      Overview Manuals Common Applications Product Precautions
      Emerson A6370D is a one-channel speed monitor with display for the AMS 6300 SIS overspeed protection system. Three monitors can be used with the system backplane and terminal hardware to implement independent speed channels and voted protection logic.
      • Provides one independent overspeed channel
      • Includes a local display for channel values
      • Operates in a three-monitor AMS 6300 SIS architecture
      • Supports system alarm and trip functions

      Record the sensor type, pulse count, speed range, setpoints and relay allocation before replacing A6370D. Test the channel with a traceable frequency source and prove display, alarm, trip and system voting before restoring the protected machine.

      Important Notice: Verify A6370D from the physical marking and current manufacturer documentation before installation or configuration.

      Important Notice: Use these model-specific records together with the current manufacturer publication and the installed-system documentation.

      Steam-turbine overspeed protection
      Supervises one independent shaft-speed channel.
      Gas-turbine speed trip
      Provides a dedicated frequency-to-speed protection path.
      Compressor train overspeed logic
      Contributes one channel to a voted protection system.
      AMS 6300 SIS channel replacement
      Restores a displayed A6370D channel while preserving system voting.
      Read the applicable Emerson instructions before work. Verify A6370D and the installed system configuration.
      1
      Confirm A6370D and do not substitute A6370D/DP unless Profibus is explicitly required.
      2
      Place the overspeed protection system in the approved bypass or maintenance state.
      3
      Record sensor type, pulse count, frequency range and speed units.
      4
      Capture alert, danger and trip setpoints with their delay and voting assignments.
      5
      Verify redundant 24 VDC system power before card work.
      6
      Use ESD controls and protect the rack connector.
      7
      Inject low, normal and trip-level frequencies after installation.
      8
      Prove the local display, channel trip and system voting before release.

      FAQS

      • What does the D suffix identify on Emerson A6370D?
        The ordering table identifies A6370D as the one-channel speed monitor with display.
      • How is Emerson A6370D different from A6370D/DP?
        A6370D/DP adds the Profibus option; the exact A6370D order code does not include that option.
      • How many speed inputs does Emerson A6370D monitor?
        Each A6370D provides one independent speed channel.
      • Why are three Emerson A6370D monitors commonly installed?
        The AMS 6300 SIS architecture uses three independent monitors so the backplane and relay arrangement can implement the required protection voting.
      • Which backplane family is used with Emerson A6370D?
        The system documentation pairs the monitors with A6371-series backplanes.
      • Which terminal blocks are documented with Emerson A6370D?
        The AMS 6300 SIS manual identifies A6380 or A6381 terminal hardware.
      • What data must be preserved before changing Emerson A6370D?
        Preserve sensor selection, pulses per revolution, speed range, setpoints, delays, relay allocation and system voting.
      • How should Emerson A6370D be proof-tested?
        Apply traceable input frequencies below and above each configured threshold and verify display, alarm, channel trip, backplane output and voted system response.
