C7.1 Industrial Engine and Generator Set Caterpillar


Multiposition Switch Setup

Usage:

C7.1 770
注: 只有未安装可选的 PTO 开关时,才可启用多位油门开关。

多位油门开关为可选的油门输入。 最多可使用四个开关。 使用四个开关可选择最多 16 个速度。

如果安装有可选的发动机中间转速开关,则多位油门开关最多可具有三个开关。 使用三个开关可选择最多 8 个速度。

当选择电子维修工具的"油门配置屏幕"上的多位开关"油门类型"时,将会需要更多信息。

开关输入数量

此参数为待使用的开关总数。 开关可以是单个开关或联动旋转开关。

表 1
范围     默认值    
1 到 4     0    

物理位置

此参数不可编程设定。 此参数用于指示旋转开关的位置。

输入 4、输入 3、输入 2、输入 1

这些可以查看的不可编程设定参数的数量取决于 "Number of Switch Inputs(开关输入数量)"参数中编程设定的值。 "Open(开路)"表示开关处于 OFF(断开)位置。 "Ground(接地)"表示开关处于 ON(接通)位置。

物理位置启用

如果从下拉菜单中选择了 "Yes(是)",则 ECM 会将发动机转速设定为"发动机转速"中针对物理位置定义的开关配置而编程设定的值。

表 2
    默认值    

是    
否    

逻辑位置

逻辑位置是用户需要的特定物理位置的顺序。

表 3
四个开关时的范围     默认值    
1 到 16     1    

发动机转速(单位 RPM)

"发动机转速"是针对多位油门开关的特定位置编程设定的发动机转速。

如果 ECM 检测到配置为 "No(否)"的开关组合,则将会产生一个故障代码。 在这种情况下,ECM 将忽略多位开关,直到钥匙开关从断开循环到接通。

表 4
范围     默认值    
编程设定的低怠速到编程设定的高怠速     0
