WOODWARD 9903-226 调节器现货模块
CPU主板及输入/输出板依次拆下,进行吹扫、清扫后再依次原位安装好,将全部连接恢复后送电并启动PLC主机。认真清扫PLC箱内卫生;
(2)每三个月更换电源机架下方过滤网;
三、检修前准备、检修规程
(1)检修前准备好工具;
(2)为保障元件的功能不出故障及模板不损坏,必须用保护装置及认真作防静电准备工作;
(3)检修前与调度和操作工联系好,需挂检修牌处挂好检修牌;
四、设备拆装顺序及方法
(1)停机检修,必须两个人以上监护操作;
(2)把CPU前面板上的方式选择开关从“运行”转到“停”位置;
(3)关闭PLC供电的总电源,然后关闭其它给模坂供电的电源;
(4)把与电源架相连的电源线记清线号及连接位置后拆下,然后拆下电源机架与机柜相连的螺丝,电源机架就可拆下;
(5)CPU主板及I/0板可在旋转模板下方的螺丝后拆下;
(6)安装时以相反顺序进行
五、检修工艺及技术要求
(1)测量电压时,要用数字电压表或精度为1%的表测量
(2)电源机架,CPU主板都只能在主电源切断时取下;
(3)在RAM模块从CPU取下或插入CPU之前,要断开PC的电源,这样才能保证数据不混乱;
(4)在取下RAM模块之前,检查一下模块电池是否正常工作,如果电池故障灯亮时取下模块PAM内容将丢失;
(5)输入/输出板取下前也应先关掉总电源,但如果生产需要时I/0板也可在可编程控制器运行时取下,但CPU板上的QVZ(超时)灯亮;
(6)拨插模板时,要格外小心,轻拿轻放,并运离产生静电的物品; condition circuit breaker, disconnector and grounding switch position line and bus operation condition public equipment operation condition station power operation condition other important parameter quantity control and regulation the operator controls and regulates all computer control objects and computer monitoring system equipment through the operator workstation.
