ABB FI830F 逻辑控制器

1)ABB FI830F风扇的更换

风扇轴承的设计工作寿命为30000小时，为了维护晶闸管设备的有效性，在使用期满时应及时更换。

2)ABB FI830F印刷电路板的更换

印刷电路板包含静电敏感元件，在触摸一块印刷电路板之前，执行工作人员自己进行静电放电，做到这一点简单的方法是触摸一下一个导电接地导体，例如插座的接地线。

3）ABB FI830F晶闸管模块的更换

晶闸管模块是通过自攻螺丝安装的，当一个模块更换时，散热器支撑表面清扫并且在晶闸管模块上涂上一层新的导热有。使用和原来长度相同的公制螺钉和固定件去固定模块。

1) Replacement of ABB FI830F fan

The designed working life of the fan bearing is 30,000 hours, and in order to maintain the effectiveness of the thyristor equipment, it should be replaced in time when the use expires.

2) Replacement of ABB FI830F printed circuit board

Printed circuit boards contain electrostatic sensitive components, and before touching a printed circuit board, the executive can discharge electrostatic discharge himself. A simple way to do this is to touch a conductive ground conductor, such as the ground wire of an outlet.

3) Replacement of ABB FI830F thyristor module

Thyristor modules are installed by self-tapping screws. When a module is replaced, the radiator support surface is cleaned and a new layer of thermal conductivity is applied to the thyristor module. Use metric screws and fasteners of the same length as the original to secure the module.
