Firmware Flash Compatibility
The relay architecture supports configurable protection and monitoring functions through firmware features associated with the 369 platform. The adaptive motor learning function allows thermal and operating characteristics to be established for the monitored motor. The integrated communications ports provide configuration access and operational data exchange through RS232 and RS485 interfaces. Firmware compatibility should be verified against the installed hardware revision before maintenance or software updates.
Frequently Asked Questions
Q: What communication interfaces are available on the 369-HI-R-M-0-0-H-E?
A: The relay provides one non-isolated RS232 communication port together with one RS485 communication port for configuration and system communication.
Q: What additional functions are provided by the M option?
A: The M option adds power metering parameters including kW, kvar, kVA, kWh, MWh, kvarh, Mvarh, power factor, and frequency. It also provides programmable analog outputs with selectable ranges of 0-1 mA, 0-20 mA, or 4-20 mA.
Q: Which operating events can be stored by the relay?
A: Event triggers include power failure, alarms, self test, inhibit, trip conditions, and waveform capture. With the M option installed, the relay stores the most recent 512 recorded events.
Field Installation Guidelines
- Install the relay in accordance with the specified control power range before energizing the protection circuit.
- Route communication wiring separately from high-current conductors to reduce electrical interference.
- Maintain proper grounding practices for communication cable shields according to the system grounding design.
- Mount the relay away from strong magnetic fields and high-current bus conductors as recommended by the manufacturer.
- Verify all current transformer, voltage transformer, and control wiring before enabling protection functions.
- When analog outputs are used, ensure that connected loads remain within the specified maximum resistance for the selected output range.
- If the relay includes the conformal coating option, avoid mechanical damage to the coated surfaces during installation or maintenance.
