Setelah shutdown tak terencana akibat gangguan pasokan PLN dan petir, alarm dan sinyal pada DCS tidak sepenuhnya kembali normal. ### Lingkup pekerjaan - **Troubleshooting DCS dan HMI.** Process overview, status sinyal di operator station, alarm dan event yang aktif, serta keterkaitan field signal, modul I/O, controller dan HMI. Alarm yang valid dipisahkan dari false alarm. - **Flowmeter dan totalizer.** Flowmeter CB1 hunting meski tidak ada aliran. Flowmeter CY1 tidak memberi pembacaan di HMI, dan sinyal totalizer-nya terlalu lemah untuk modul I/O DCS. Signal tracing dan injeksi menunjukkan modul I/O tidak rusak. Gangguan pada CY1 ada di controller flowmeter dan totalizer, bukan di I/O DCS. - **Verifikasi sinyal I/O.** Pemeriksaan input dari lapangan ke DCS, uji fungsi modul I/O, simulasi sinyal dan response HMI, untuk menentukan apakah gangguan berasal dari DCS atau dari lapangan dan controller. - **False alarm.** Alarm ditelusuri satu per satu melalui alarm dan event log 800xA: review log, konfirmasi operator, klasifikasi alarm asli dan palsu, pemeriksaan logika alarm, pembersihan dan pengujian ulang. False alarm yang terus muncul dapat mengurangi kewaspadaan operator terhadap alarm proses yang asli. - **Koreksi logika alarm.** Alarm terkait kondisi abnormal setelah gangguan listrik, kemungkinan sinyal high dan low muncul bersamaan pada logika alarm. Konfigurasi alarm dibersihkan dan dikoreksi. Alarm yang tersisa sesuai kondisi lapangan sebenarnya. - **Konsistensi proses dan HMI.** Ditemukan potensi ketidaksesuaian: beberapa halaman DCS tidak update, product tank pada HMI mungkin berbeda dari kondisi nyata, jalur pipa perlu diverifikasi, dan dokumen P&ID dan PFD sulit ditemukan sehingga perlu didokumentasikan ulang. - **Temuan tambahan.** Panel battery charger tidak berfungsi dan direkomendasikan untuk tindak lanjut. ## Foto lapangan - TBBM Lomanis: Modul ABB dan terminal kabel di kabinet ## Kontak - Perusahaan: PT Citia Engineering Indonesia - Email: services@citiaengineering.com - Telepon: +62 21 278 20286 - Kantor: Jl.
