Product Introduction
The GE 369-HI-R-0-0-0-0-E is a Multilin 369-series motor management relay built for protection and diagnostics of three-phase AC motors. It combines current-based thermal overload, ground fault, phase unbalance, stall/jam, and start management with 12 built-in RTD inputs for stator and bearing temperature monitoring.
This configuration carries the “R” RTD option and the “E” enhanced diagnostics/faceplate, making it suitable for critical motors where temperature trending and event records matter. Control power covers the HI range, typically 50–300 VDC / 60–265 VAC, and the relay communicates via RS485 Modbus RTU for SCADA or PLC integration.

Quality Control Process (DYNAMIC GENERATION)
- Ordering code verification: Confirm 369-HI-R-0-0-0-0-E matches exactly, especially the “R” RTD option and “E” enhanced faceplate.
- Control power and boot test: Apply rated HI supply and verify stable startup, display operation, and LED status.
- RTD channel check: Connect simulated Pt100/RTD sensors and verify temperature readings across multiple channels using a precision resistor box or Fluke calibrator.
- CT and ground-fault injection: Inject phase and ground CT secondary current to confirm overload, unbalance, stall, and ground-fault responses.
- Relay and communication validation: Energize trip/alarm relays, verify contact operation, then test RS485 Modbus RTU register reads. Pack with anti-static shielding and terminal protection.
Replacement Pitfall Guide (DYNAMIC GENERATION)
❗ Do not substitute “0” for “R” or vice versa. The 369-HI-R-0-0-0-0-E has 12 RTD inputs; a “0” RTD version will lack those terminals and cannot monitor winding/bearing temperature the same way.
❗ Verify RTD wiring and sensor type. Mixing Pt100, Pt1000, or Ni120 settings causes false temperature readings and may mask real overheating.
❗ Confirm CT ratio and polarity. Incorrect CT scaling or reversed phase wiring triggers nuisance overload, unbalance, or ground-fault trips.
❗ Check RS485 address and baud rate. The relay boots fine, but SCADA will see nothing if the Modbus ID, parity, or baud rate does not match the network.
Keep these in mind and you’ll cut 90% of rework time.
