1769-L23E-QBFC1B以太網/IP控制器
GTO系列面板關鍵系統、警報和處理要求關鍵警報指示器和系統功能需要獨立和冗余的保護硬件和/或機械聯鎖。重啟電源時，請至少等待10秒鐘，然后在關閉面板電源后恢復面板電源。關閉和打開電源可能會損壞面板。如果無法正確讀取屏幕，例如，如果背光燈不工作，則可能很難或不可能識別功能。如果不立即執(zhí)行，可能會產生危險的功能，如燃油切斷，必須獨立于面板提供。機器的控制系統設計必須考慮背光燈不再工作以及操作員無法控制機器或在控制機器時出錯的可能性。失去控制? 任何控制方案的設計者必須考慮控制路徑的潛在故障模式，對于某些關鍵控制功能，提供在路徑故障期間和之后實現安全狀態(tài)的方法。關鍵控制功能的示例包括緊急停機和超程停機、斷電和重啟。? 必須為關鍵控制功能提供單獨或冗余的控制路徑。? 系統控制路徑可能包括通信鏈路。必須考慮意外傳輸延遲或鏈路故障的影響。? 遵守所有事故預防規(guī)定和當地安全指南。? 在投入使用之前，必須對該設備的每個實施進行單獨和徹底的測試，以確保其正常運行。? 機器控制系統的設計必須考慮背光燈不再工作、操作員無法控制機器或在機器控制中出錯的可能性。不遵守這些說明可能導致死亡、重傷或設備損壞。

請參閱NEMA ICS 1.1（最新版本）、“固態(tài)控制應用、安裝和維護的安全指南”和NEMA ICS7.1（最新版）、“可調速驅動系統的結構安全標準和選擇、安裝和操作指南”或適用于您特定位置的同等標準。非預期設備操作? 不要將此設備用作關鍵系統功能（如電機啟動/停止或電源控制）的唯一控制手段。? 不要將此設備用作關鍵警報的唯一通知設備，例如設備過熱或過電流。不遵守這些說明可能導致死亡、重傷或設備損壞。處理LCD面板以下特性是LCD面板特有的，被視為正常行為：? LCD屏幕可能會顯示某些圖像的亮度不均勻，或者從指定的視角外觀看時可能會出現差異。屏幕圖像的側面也可能出現擴展陰影或串擾。? LCD屏幕像素可能包含黑白色斑點，顏色顯示可能已發(fā)生變化。? 當同一圖像長時間顯示在屏幕上時，圖像更改時可能會出現后圖像。注意：定期更改屏幕圖像，并嘗試長時間不顯示同一圖像。如果面板損壞，任何液體接觸到您的皮膚，請立即用自來水沖洗該區(qū)域至少15分鐘。如果液體進入眼睛，立即用自來水沖洗眼睛至少15分鐘，并咨詢醫(yī)生。
GTO Series of Panels
Critical Systems, Alarms, and Handling Requirements Critical alarm indicators and system functions require independent and redundant protection hardware and/or mechanical interlocks. When you cycle power, wait at least 10 seconds before restoring the power to the panel after it has been turned off. Switching the power OFF and ON can damage the panel. In the event the screen cannot be properly read, for example, if the backlight is not functioning, it may be difficult or impossible to identify a function. Functions that may present a hazard if not immediately executed, such as a fuel shut-off, must be provided independently of the panel. The machine’s control system design must take into account the possibility of the backlight no longer functioning and the operator being unable to control the machine or making mistakes in the control of the machine.LOSS OF CONTROL ? The designer of any control scheme must consider the potential failure modes of control paths and, for certain critical control functions, provide a means to achieve a safe state during and after a path failure. Examples of critical control functions are emergency stop and overtravel stop, power outage, and restart. ? Separate or redundant control paths must be provided for critical control functions. ? System control paths may include communication links. Consideration must be given to the implications of unanticipated transmission delays or failures of the link. ? Observe all accident prevention regulations and local safety guidelines. ? Each implementation of this equipment must be individually and thoroughly tested for proper operation before being placed into service. ? The machine control system design must take into account the possibility of the backlight no longer functioning and the operator being unable to control the machine, or making errors in the control of the machine. Failure to follow these instructions can result in death, serious injury, or equipment damage.
For additional information
refer to NEMA ICS 1.1 (latest edition), "Safety Guidelines for the Application, Installation, and Maintenance of Solid State Control" and to NEMA ICS 7.1 (latest edition), "Safety Standards for Construction and Guide for Selection, Installation and Operation of Adjustable-Speed Drive Systems" or their equivalent governing your particular location.UNINTENDED EQUIPMENT OPERATION ? Do not use this equipment as the only means of control for critical system functions such as motor start/stop or power control. ? Do not use this equipment as the only notification device for critical alarms, such as device overheating or overcurrent. Failure to follow these instructions can result in death, serious injury, or equipment damage.Handling the LCD Panel The following characteristics are specific to the LCD panel and are considered normal behavior: ? LCD screen may show unevenness in the brightness of certain images or may appear different when seen from outside the specified viewing angle. Extended shadows, or crosstalk may also appear on the sides of screen images. ? LCD screen pixels may contain black and white colored spots and color display may seem to have changed. ? When the same image is displayed on the screen for a long period, an after-image may appear when the image is changed. NOTE: Change the screen image periodically and try not to display the same image for a long period of time.If the panel is damaged and any liquid comes in contact with your skin, immediately rinse the area with running water for at least 15 minutes. If the liquid gets in your eyes, immediately rinse your eyes with running water for at least 15 minutes and consult a doctor.
