914G Compact Wheel Loader and IT14G Integrated Toolcarrier Transmission Electronic Control System Caterpillar


Manual Operation of Secondary Steering

Usage:

IT14G 1WN
系统运作描述:

主转向流量开关是控制装置的输入设备。 当转向系统中没有液压油流量时,流量开关打开。 当开关打开并且机器移动时,控制装置激活辅助转向继电器。 这将主转向流量指示灯转至接通。 辅助转向继电器触点关闭。 这激活辅助转向继电器。 如果发生辅助转向故障,控制装置可能不指示故障。 如果发生这一情况,检查以下区域。

测试步骤 1. 检查电路是否正常工作

  1. 检查来自先导辅助转向继电器的线束配线。

  1. 检查来自主辅助转向继电器的线束配线。

  1. 检查辅助转向开关和蓄电池正极之间的线束配线。

  1. 检查辅助转向马达和地面之间的线束配线,以及主辅助转向继电器和地面之间的线束配线。

  1. 检查主辅助转向继电器和辅助转向马达之间的线束配线。

  1. 检查电源以及地面和控制装置之间的情况。

结果:

  • 应找出故障。 - 机器应正常工作。停止
