ComAp
Selected ComAp controller, monitoring, communications and power-management applications.指定 ComAp 控制器、監察、通訊同電力管理應用。
Identification is not compatibility.識別唔等於兼容。 A matching-looking front panel or similar model name does not confirm wiring, firmware, I/O, communication, feature or application equivalence.面板外觀相似或者型號名稱接近，唔代表接線、firmware、I/O、通訊、功能或者應用等同。
02 · Synchronising & load sharing同步及負載分配
Multi-source control needs a complete system view.多電源控制需要完整系統視野。
Selected applications may involve generator-to-generator or generator-to-mains synchronising, load sharing, breaker control, protection and power-management logic. The switchgear, CT/VT arrangement, breaker interface, protection philosophy and operating sequence must be reviewed together.指定應用可能涉及發電機對發電機或發電機對市電同步、負載分配、斷路器控制、保護同電力管理邏輯；開關設備、CT/VT 安排、斷路器介面、保護理念同運作次序要一併評估。
- Single-line diagram and operating sequence單線圖及運作次序
- Generator, alternator and engine data發電機、交流發電機及引擎資料
- Breaker, CT/VT and protection interface斷路器、CT/VT 及保護介面
- Governor and AVR control interface調速器及 AVR 控制介面
- Communications, remote monitoring and alarms通訊、遙距監察及警報
- Commissioning plan and site safety controls調試計劃及現場安全控制
03 · EFC
Electronic fuel and engine-speed control.電子燃油及引擎速度控制。
EFC enquiries may involve an electronic speed controller, actuator, magnetic pickup, fuel-system interface, power supply, speed setting and interaction with a genset controller.EFC 查詢可能涉及電子速度控制器、actuator、magnetic pickup、燃油系統介面、供電、速度設定，同發電機控制器之間嘅互動。
The exact architecture differs by engine and fuel system. Part numbers, wiring and operating symptoms are essential.實際架構會按引擎同燃油系統而異；零件號碼、接線同運作現象係必要資料。
- Controller and actuator identification控制器及 actuator 識別
- Pickup signal and speed-reference reviewPickup 訊號及速度參考檢視
- Supply, grounding and wiring assessment供電、接地及接線評估
- Stability, gain and response considerations穩定度、gain 及反應考慮
- Interface with start/stop and genset control同啟停及發電機控制嘅介面
- Fault symptom and recent-change review故障現象及近期變更檢視
04 · Controller power packs控制器電源包
Control power designed around the electrical requirement.按實際電氣需要設計控制電源。
Controller power is more than a nominal voltage. The supply must suit the controller, load profile, start and crank conditions, protection, grounding, terminals, enclosure and operating environment.控制電源唔只係一個標稱電壓；供應要配合控制器、負載特性、啟動及 cranking 情況、保護、接地、端子、外殼同運作環境。
VInput and output voltage range輸入及輸出電壓範圍
AContinuous and peak current持續及峰值電流
↯Transient and polarity protection突波及極性保護
tHold-up and start behaviourHold-up 及啟動行為
Specific protection, isolation, hold-up and certification claims apply only when stated on the confirmed product specification.指定保護、隔離、hold-up 同認證聲明，只會喺已確認產品規格列明時適用。
05 · Replacement & retrofit更換及改裝
Replace the function—not just the faceplate.更換嘅係功能，而唔只係面板。
An obsolete or unavailable controller may require a same-family replacement, a migration to another model, an interface module, rewiring, panel modification or a wider control upgrade. The safest path depends on the existing design and documentation.過時或者缺貨控制器可能需要同系列更換、轉移到另一型號、加入介面模組、重新接線、修改控制箱或者更全面控制升級；最穩妥路線視乎現有設計同文件。

Structured information makes troubleshooting faster.有系統資料令故障排查更有效。
For an initial review, send clear identification, the application, wiring or schematic, alarms, operating symptoms, recent work and safe test results where available.初步評估時，請提供清晰識別、應用、接線或圖則、alarm、運作現象、近期工作，同喺安全情況下取得嘅測試結果。
Technical enquiry技術查詢
Build a clearer project brief.建立更清晰項目 brief。
This tool prepares an email summary. It does not confirm a replacement, quotation, compatibility or safe work method.呢個工具會整理電郵摘要；唔代表已確認更換、報價、兼容性或者安全工作方法。
Do not include passwords or unsafe live-test instructions.請勿提供密碼或者不安全帶電測試指示。
Technical questions技術常見問題
Confirm before you connect.接駁之前先確認。
Power and engine-control systems can be safety-critical. Assumptions must be replaced with drawings, data and controlled testing.動力同引擎控制系統可以涉及安全關鍵；假設必須由圖則、數據同受控測試取代。
A photo may help identify the family, but it is not enough to confirm compatibility. Review the complete part number, revision, wiring, I/O, communications, supply, engine or genset data and application logic.相片可以幫助辨認系列，但不足以確認兼容性；要核對完整零件號碼、版本、接線、I/O、通訊、供電、引擎或發電機組資料同應用邏輯。
No blanket claim is made. Support is for selected products and applications, subject to model identification, documentation, access to required tools or software, parts availability and technical review.唔會作全面承諾；支援只限指定產品同應用，並視乎型號識別、文件、所需工具或軟件存取、零件供應同技術評估。
Provide engine and fuel-system details, existing controller and actuator part numbers, supply voltage, rated speed, speed-control mode, wiring or schematic, symptom, alarms and recent changes.請提供引擎及燃油系統資料、現有 controller 同 actuator 零件號碼、供電電壓、額定轉速、速度控制模式、接線或圖則、故障現象、alarm 同近期變更。
No. Selection should also consider continuous and peak current, start-up behaviour, voltage tolerance, isolation, transient and reverse-polarity protection, hold-up needs, grounding, terminals, enclosure and environment.唔可以。亦要考慮持續及峰值電流、啟動行為、電壓容差、隔離、突波及反極性保護、hold-up 需要、接地、端子、外殼同環境。
Site work depends on agreed scope, competency, access, permits, isolation procedures, drawings and safety arrangements. Do not work on live or safety-critical equipment without authorised qualified personnel and site controls.現場工作視乎約定範圍、能力、進場、許可、隔離程序、圖則同安全安排；未有獲授權合資格人員同現場控制，唔應該喺帶電或安全關鍵設備工作。
Clear next steps清晰下一步
Send the model, application and symptom—not just a product name.提供型號、應用同故障現象，而唔只係產品名稱。
A clearer technical enquiry helps identify whether the next step is component selection, configuration, troubleshooting, interface design or retrofit assessment.更清晰技術查詢有助判斷下一步係組件選型、設定、故障排查、介面設計定改裝評估。
