1769-L23E-QBFC1B以太网/IP控制器
GTO系列面板关键系统、警报和处理要求关键警报指示器和系统功能需要独立和冗余的保护硬件和/或机械联锁。重启电源时，请至少等待10秒钟，然后在关闭面板电源后恢复面板电源。关闭和打开电源可能会损坏面板。如果无法正确读取屏幕，例如，如果背光灯不工作，则可能很难或不可能识别功能。如果不立即执行，可能会产生危险的功能，如燃油切断，必须独立于面板提供。机器的控制系统设计必须考虑背光灯不再工作以及操作员无法控制机器或在控制机器时出错的可能性。失去控制 任何控制方案的设计者必须考虑控制路径的潜在故障模式，对于某些关键控制功能，提供在路径故障期间和之后实现安全状态的方法。关键控制功能的示例包括紧急停机和超程停机、断电和重启。 必须为关键控制功能提供单独或冗余的控制路径。 系统控制路径可能包括通信链路。必须考虑意外传输延迟或链路故障的影响。 遵守所有事故预防规定和当地安全指南。 在投入使用之前，必须对该设备的每个实施进行单独和彻底的测试，以确保其正常运行。 机器控制系统的设计必须考虑背光灯不再工作、操作员无法控制机器或在机器控制中出错的可能性。不遵守这些说明可能导致死亡、重伤或设备损坏。
有关更多信息
请参阅NEMA ICS 1.1（最新版本）、“固态控制应用、安装和维护的安全指南”和NEMA ICS7.1（最新版）、“可调速驱动系统的结构安全标准和选择、安装和操作指南”或适用于您特定位置的同等标准。非预期设备操作 不要将此设备用作关键系统功能（如电机启动/停止或电源控制）的唯一控制手段。 不要将此设备用作关键警报的唯一通知设备，例如设备过热或过电流。不遵守这些说明可能导致死亡、重伤或设备损坏。处理LCD面板以下特性是LCD面板特有的，被视为正常行为： LCD屏幕可能会显示某些图像的亮度不均匀，或者从指定的视角外观看时可能会出现差异。屏幕图像的侧面也可能出现扩展阴影或串扰。 LCD屏幕像素可能包含黑白色斑点，颜色显示可能已发生变化。 当同一图像长时间显示在屏幕上时，图像更改时可能会出现后图像。注意：定期更改屏幕图像，并尝试长时间不显示同一图像。如果面板损坏，任何液体接触到您的皮肤，请立即用自来水冲洗该区域至少15分钟。如果液体进入眼睛，立即用自来水冲洗眼睛至少15分钟，并咨询医生。
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.
