ComAp InteliLite 4 AMF 20

Single-generator AMF controller

InteliLite 4 AMF 20 provides single-generator automatic mains-failure control. Its Modbus monitoring path uses a fitted communication module. Checking that module first avoids specifying an RS-485 connection to a controller that only has its standard USB and CAN interfaces.

Single-generator AMF controller

Compatibility

Documented Modbus RTU and TCP interface

Optional CM-RS232-485 serial module or Ethernet communication module; integrated USB is for configuration

Do not copy the AMF 25 onboard RS-485 wiring assumption. The AMF 20 serial path uses CM-RS232-485; a TCP path needs the Ethernet option.

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
IP65 front panel and IP20 rear; standard operating temperature -20 to +70 °C.2
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. Open the saved InteliConfig application, identify the fitted module and enable its Modbus interface.

    Export the configurable Modbus table and use those addresses and data types when defining Edge observations.

  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.
