Rhts-034 _verified_ 【2027】

: Tracks phase-to-phase and phase-to-neutral voltages, as well as frequency for both primary and secondary power sources.

| Interval | Activity | Remarks | |----------|----------|---------| | | Visual inspection of inlet/outlet seals; check for leaks. | Replace O‑rings if any seepage observed. | | Weekly | Verify PID control performance using a temporary set‑point shift (+5 °C). | Adjust auto‑tune if deviation > 0.3 °C. | | Quarterly | Clean heat‑exchange plates (non‑abrasive solvent) and inspect for fouling. | Record pressure drop across the core; > 10 % increase → service. | | Annually | Firmware version audit; apply latest security patches. | Keep a change‑log in the asset management system. | | Every 5 Years | Full hydraulic pressure test (1.5 × rated pressure). | Required for compliance with IEC 61800‑3. | rhts-034
