4.仪表系统调试程序

图一为仪表系统调试程序方框图。本着分层隔离、平行作业的方法，本方案将系统调试分划为经下四个层次：

4.1第一层次：DCS及辅助仪表盘仪表调试

在这一层次中，通过设置断点1、2，使DCS调试与辅助仪表盘仪表调试相对独立、互不干扰，从而便于实现对这两个工序的平行作业，并可避免因设备状态不正常或接线错误等原因造成设备的损坏。

4.2第二层次：控制室内部系统调试

此层次在不连接控制至现场电缆情况下，对DCS机柜、压缩

机盘、火警盘等的系统调试。对于其中的联锁系统调试能否做早、

做好、做扎实，对“消除隐患、掌握主动、赢得时间”意义重大。

4.3第三层次：全装置仪表二次联校

根据现场施工及工艺试车进度要求，逐点连接控制室至现场电缆，通过在现场加信号进行回路试验，并陆续投用。

4.4第四层次：应用软件参数的进一步调整

此为在单体试车、联动试车之前、之中、之后，对某些仪表参数如复杂调节系统的计算系数、偏置值、延迟时间、设定值及

比例度、积分、微分时间等的试验调整，以获得最佳运行工况。
