Deep Sea Electronics DSE7320 MKII

Single-generator AMF controller

DSE7320 MKII monitors both a generator and its mains supply for automatic mains-failure operation. Its integrated RS-485 Modbus RTU port is the straightforward monitoring route. USB is used for DSE Configuration Suite, and DSENet serves expansion devices.

The DSE7310 MKII is the auto-start sibling. A DSE7320 MKII does not acquire native Ethernet simply because a DSE remote-communications accessory appears on the product page.

AccuracySupported with conditions
The documentation identifies electrical and operating measurements for this plant role. CT configuration and measurement location determine how those values are used.12
SecurityNot yet assessed
The cited documentation does not establish an authenticated, encrypted Edge monitoring connection.
ReliabilityNot yet assessed
The controller application distinguishes operating conditions and alarms. Retain communication availability alongside the plant readings.
RuggednessSupported with conditions

ScalabilityNot yet assessed
Assign one device identity per controller and keep generator, mains and busbar measurements separate.
LifecycleSupported with conditions
Retain the exact model documentation and configuration when replacing a controller or communication module.12

Setup

  1. Save the DSE Configuration Suite file, set the RS-485 Modbus address and serial settings, and obtain the DSE Gencomm or configured page definitions for the required readings.

    Start with voltage, frequency and operating mode, using each published unit and scale.

  2. Record CT ratios and the physical measurement location.

    Compare the first electrical values with the controller display before using them in totals or trends.

  3. Keep missing responses distinct from a stopped generator.

    Store communication availability beside running state so a disconnected cable does not look like healthy standby.

  4. Build a read-only point list for monitoring.

    Remote start, synchronisation and breaker operation require a separate control design with the existing panel interlocks and feedback.
