参数编程设置

电子点火系统控制模块(EIS控制模块)和电子控制模块(ECM)具有几个可根据具体安装情况编程设置的参数。编程设置这些参数需要用到数字诊断工具(DDT)或卡特彼勒电子技师(Cat ET)。

对于DDT，这些参数分属下述3个菜单： "用户规定参数(CUSTOMER SPECIFIED PARAMETERS) (C.S.P.)", "正时(TIMING)" 和 "氧气测试(O2 TEST)"。对于每一个参数的名称，请参看表1。

关于这些参数的描述，请参阅系统操作/测试和调整, "电子控制系统参数"。

如果更换模块，适当的参数必须从旧模块复制到新模块。可先将设置值记录在纸上，然后编程设置到新模块内。或者，复制过程可用卡特彼勒电子技师(ET)"复制配置(Copy Configuration)"特性来完成。

注意

在发动机运转时改变参数会导致发动机运转反常。这会造成发动机损坏。除非另有说明，否则只能在发动机停机时改变参数设置。
