8200-203  配置连接 数字超速保护跳闸装置

【产品详情】

8200-204 型的三个单元以三分之二的投票配置连接，因此如果任何单个单元发生故障，ProTech 系统仍将提供正确的输出。

Part 8200-204 是数字超速保护跳闸装置。该系统由伍德沃德制造，作为其ProTech 203系列的一部分。8200-204 型是该系列中的通电跳闸版本之一，也是唯一具有 220 V 交流输入的通电跳闸型号。

三个独立的磁性拾音器可感测原动机速度并监控超速情况。如果检测到条件，则会激活跳闸继电器。该系统利用三个相同的单独速度感应单元，这些单元连接并配置为三分之二的投票，从而确保了准确性和可靠性。此配置还允许在线测试和在发生故障时更换单个单元。

8200-204 系统中的每个单元都有一个带触摸板、数字显示屏和 LED 指示灯的前面板。有单独的 LED 指示跳闸的速度感应单元、MPU 或其接线故障以及单元 CPU 中的错误。如果设备跳闸，则有一个报警输出以及 LED。

前面板是 8200-204 编程的地方。通过按键开关控制在监控模式和程序模式之间切换的访问。所有三个单元都使用相同的钥匙锁进行保护，以防止对系统进行任何未经授权的更改。

为确保正确安装 8200-204 系统，请参阅伍德沃德 ProTech 203 超速保护系统安装和操作手册 85205 （F）。本手册可在线获取，涵盖详细信息，包括位置注意事项、其他产品规格以及接线和一般安装说明。

【英文介绍】

The three units of the Model 8200-204 are connected in a two-thirds voting configuration, so if any single unit fails, the ProTech system will still provide the correct output.

Part 8200-204 is a digital overspeed protection trip device. The system is manufactured by Woodward as part of its ProTech 203 series. The Model 8200-204 is one of the power trip versions in the family and the only one with a 220 V AC input.

Three independent magnetic pickups sense the prime mover speed and monitor overspeed. If a condition is detected, the trip relay is activated. The system makes use of three identical individual speed sensing units that are connected and configured for two-thirds voting, thus ensuring accuracy and reliability. This configuration also allows for online testing and replacement of individual units in the event of a failure.

Each unit in the 8200-204 system has a front panel with a touchpad, digital display, and LED indicators. There are separate leds to indicate a trip to the speed sensing unit, the MPU or its wiring failure, and an error in the unit CPU. If the device trips, there is an alarm output and LED.

The front panel is where the 8200-204 is programmed. Access to switch between monitor mode and program mode is controlled by a key switch. All three units are protected with the same key lock to prevent any unauthorized changes to the system.

To ensure proper installation of the 8200-204 system, refer to the Woodward ProTech 203 Overspeed Protection System Installation and Operation Manual 85205 (F). This manual is available online and covers detailed information, including location precautions, other product specifications, and wiring and general installation instructions.
