    產品內容介紹

    1392-B040-RF-MC-A-F1數字交流模塊

    作為防止觸電的措施設計面板外殼的門,使其只能使用鑰匙或專用工具打開,因此只有具備足夠電氣知識的授權人員(如系統設計師或維護人員)才能進入當電纜從金屬面板外殼中抽出時,應使用VW-1級或更高等級的阻燃電纜安裝外部開關或斷路器。由于FA-M3的電源模塊沒有內置電源開關,因此系統應設計一個外部開關或斷路器:-符合EN60947,-可以斷開所有載流導體。-標記為FA-M3的電源開關,其ON和OFF位置清楚標記安裝在FA-M3附近,操作員可觸及范圍內,-不會受到附近物體的阻礙,從而阻礙其操作,并且-不會斷開FA-M3的接地線。-使用以下外部電源裝置連接直流電源模塊和I/O模塊。-輸出電路通過雙重或加強絕緣與危險電壓絕緣安裝了過流保護裝置。如果沒有,請在外面連接保險絲或斷路器。圖A3.40顯示了FA-M3的絕緣方塊圖。FA-M3通過基本絕緣和保護接地提供了針對每個危險電壓的電擊保護參考圖A3.40,對包含FA-M3的設備施加適當的測試電壓。不要施加過高的測試電壓。它引起了麻煩在不處理危險電壓的FA-M3模塊中,輸入輸出端子和內部電路之間的絕緣為功能絕緣或非絕緣。就安全標準而言,所有這些絕緣材料都被視為非絕緣材料。因此,在耐壓試驗中,不要在這些試塊之間施加試驗電壓。

    試運行程序

    檢查控制面板的結構和FA-M3的安裝。檢查各個模塊的安裝情況。檢查電纜,確保所有電纜的布線和連接正確,符合接線規范。FA-M3是一種精密的電子設備。在檢查使用該設備的機器或設施的絕緣時,必須特別注意避免損壞該設備。在打開電源之前,測量電源電壓以確保其符合給定的規格。檢查外部接線有兩種方法:使用萬用表一次檢查一根電纜,或實際打開電源并查找問題。出于安全原因,后一種方法可能是危險的,因此需要充分注意。通過檢查安全電路(如緊急停止電路和保護電路)的工作情況開始測試,這些電路在設備發生故障時啟動。用按鈕單步穿過機器或設施,測試每個操作模式。在自動模式下運行機器或設施的每個特定模塊,或在自動模式中對機器或設施運行獨立測試。然后,繼續整個系統的全自動操作。測試以確保當機器或設施發生異常時,安全電路正常啟動和復位連接和分離連接器和模塊連接或斷開連接器或模塊之前,確保關閉電源。在通電的情況下卸下或更換連接器或模塊可能會導致設備永久損壞。修改程序中的注意事項在修改程序后制作程序的備份副本,因為它們可能在測試運行期間被修改。

    As a measure to protect against electric shock

     design the door of the panel enclosure such that it can only be opened using a key or special tool, and thus only accessible to authorized personnel with adequate electrical knowledge such as system designers or maintenance personnel. - When the cable is drawn out of metallic panel enclosure, use a flame-retardant cable of VW-1 class or more. - Install an external switch or circuit breaker. As the power supply module of the FA-M3 does not have a built-in power supply switch, design the system with an external switch or circuit breaker which: - Is compliant with EN60947, - Can disconnect all current-carrying conductors. - Is labeled as the power supply switch for the FA-M3 with its ON and OFF positions clearly marked. - Is installed near the FA-M3, within reach of an operator, - Is not obstructed by nearby objects such that its operation is hindered, and - does not disconnect the grounding wire from the FA-M3. - Use the following external power supply unit to DC power supply modules and I/O modules. - Output circuit is insulated by double or reinforced insulation from hazardous voltage. - Overcurrent protection device is installed. If not, attach a fuse or a circuit breaker outside.Figure A3.40 shows the insulation block diagram of FA-M3. - FA-M3 provides protection against electric shock from each hazardous voltage by both basic insulation and protective earth. - Apply the appropriate test voltage to the equipment incorporating the FA-M3 by referring to Fig.A3.40. Don't apply the excessive test voltage. It causes the trouble. - In the FA-M3 module which doesn't handle hazardous voltage, the insulations between input-output terminals and internal circuits are functional insulations or non-insulations. In terms of safety standards, all of these insulations are treated as non-insulation. Therefore, in the withstand voltage test, don't apply the test voltage between these blocks.

    Test Run Procedure

    Check the construction of the control panel and the FA-M3 installation. Check the installation of the individual modules. Check cables to ensure that all cables are properly routed and connected to meet the wiring specifications. The FA-M3 is a delicate electronic device. Special care must be taken to avoid damage to the device when checking the insulation of the machine or facility that uses this device. Before turning on the power, measure the supply voltage to ensure that it conforms to the given specifications. There are two ways to check the external wiring: by using a multimeter to examine the cables one at a time, or by actually turning the power on and looking for problems. The latter method may be hazardous for safety reasons and, therefore, require adequate care. Start the test by checking the operation of safety circuits such as emergency-stop circuits and protective circuits which are actuated when the device gets into trouble. Test each operating mode by stepping through the machine or facility with push buttons. Run each of specific blocks of the machine or facility in the automatic mode or run a standalone test on the machine or facility in the automatic mode. Then, proceed to full automatic operation of the entire system. Test to make sure that safety circuits actuates and reset normally when anomalies occur in the machine or facility Attaching and Detaching Connectors and Modules Be sure to turn off the power before connecting or disconnecting connectors or modules. Removing or replacing connectors or modules with the power on may result in permanent damage to the device. ? Precautions in Modifying Programs Make a backup copy of programs after modifying them as they may be altered during a test run.
