所有电子设备都是静电敏感的，某些部件比其他部件更敏感。
为了保护这些部件免受静电损坏，必须采取特殊措施
尽量减少或消除静电放电的预防措施。
使用或靠近控制装置时，请遵循以下预防措施。
1.在对电子控制装置进行维护之前，应将静电放电
通过触摸和握住接地的金属，将身体上的电流接地
对象（管道、机柜、设备等）。
2.避免在身体上积聚静电，不要穿衣服
由合成材料制成。尽可能多地穿棉或棉混纺材料
尽可能地，因为它们不会存储尽可能多的静电电荷
合成材料。
3.保持塑料、乙烯基和泡沫塑料材料（如塑料或泡沫塑料
杯子、杯托、香烟包装、玻璃纸包装、乙烯基书籍或
文件夹、塑料瓶和塑料烟灰缸）远离控制
模块和工作区域。
4.不要将印刷电路板（PCB）从控制柜上拆下
除非对必要。如果必须从控件中移除PCB
在机柜中，请遵循以下预防措施：
 除边缘外，请勿触摸PCB的任何部分。
 请勿触摸导线、接头或
带有导电装置或手的组件。
 更换PCB时，将新PCB放在塑料防静电盒中
保护袋：在您准备好安装之前，它会一直存在。立即
从控制柜中卸下旧PCB后，将其放入
防静电保护袋。

All electronic equipment is static-sensitive, some components more than others. To protect these components from static damage, you must take special precautions to minimize or eliminate electrostatic discharges. Follow these precautions when working with or near the control. 1. Before doing maintenance on the electronic control, discharge the static electricity on your body to ground by touching and holding a grounded metal object (pipes, cabinets, equipment, etc.). 2. Avoid the build-up of static electricity on your body by not wearing clothing made of synthetic materials. Wear cotton or cotton-blend materials as much as possible because these do not store static electric charges as much as synthetics. 3. Keep plastic, vinyl, and Styrofoam materials (such as plastic or Styrofoam cups, cup holders, cigarette packages, cellophane wrappers, vinyl books or folders, plastic bottles, and plastic ash trays) away from the control, the modules, and the work area as much as possible. 4. Do not remove the printed circuit board (PCB) from the control cabinet unless absolutely necessary. If you must remove the PCB from the control cabinet, follow these precautions:  Do not touch any part of the PCB except the edges.  Do not touch the electrical conductors, the connectors, or the components with conductive devices or with your hands.  When replacing a PCB, keep the new PCB in the plastic antistatic protective bag it comes in until you are ready to install it. Immediately after removing the old PCB from the control cabinet, place it in the antistatic protective bag. To prevent damage to electronic components caused by improper handling, read and observe the precautions in Woodward manual 82715, Guide for Handling and Protection of Electronic Controls, Printed Circuit Boards, and Modules. 505 Digital Governor Manual 85017V1 vi Woodward Manual 85017V1 505 Digital Governor Woodward 1 Chapter 1. General Information Introduction This manual describes the Woodward 505 Digital Governor for steam turbines. English versions are 9907-162, 9907-163, and 9907-164. The option charts below show the differences between the part numbers. Volume 1 of this manual provides installation instructions, describes the control, and explains the configuration (programming) and operating procedures. Volume 2 includes notes on applying the control to specific applications, Service mode information, and 505 hardware specifications. This manual does not contain instructions for the operation of the complete turbine system. For turbine or plant operating instructions, contact the plant-equipment manufacturer. Manual 85018 describes the 505E Digital Governor for extraction steam turbines.

This new polyacrylate material replaces the previous silicon conformal coating and provides an improved barrier between board components and sulfur-based gases. 505 controls that have this coating will have a label on the side stating “SULFUR RESISTANT CONFORMAL COATED”. All 505 controllers shipped from Woodward with the revision letters listed below, or subsequent letters, were shipped with the new polyacrylate conformal coating material: Table 1-1. 505s with Polyacrylate Coate
