显示已在电子技师 (ET) 软件中选择变速箱/底盘 ECM 的典型屏幕。

卡特彼勒电子技师软件配备变速箱/底盘系统标定特性。 将 ET 与车辆相连即可进入标定模式。 选择变速箱/底盘 ECM。 如图 1 中所示。

设置机具操纵杆标定的典型屏幕

在选择变速箱/底盘 ECM 后,通过"维修菜单 (Service Menu)"即可进入标定步骤。 从菜单中选择"标定 (Calibrations)"。 然后选择"机具操纵杆标定 (Implement Control Lever Calibrations)"。 如图 2 中所示。

变速箱/底盘 ECM 在操纵手柄标定过程中会寻求机具控制器的整个范围。 这种标定将把缺省范围设定值改变实际范围设定值。 变速箱/底盘 ECM 会在存储器中记录这些动作。 在更换 ECM 或重新进行标定步骤之前一直使用这些范围值。

可能在电液控制阀之外单独进行操纵手柄标定。 重新标定电液控制阀后就不需要重新标定操纵手柄。

注: 电子技师屏幕上把操纵手柄称为"机具操纵杆 (Implement Control Lever)"。

    (1) 铲运斗操纵杆传感器的标定

    (2) 推土器操纵杆传感器的标定

    (3) 挡板操纵杆传感器的标定

  1. 选择正确的标定。 选择需要的选择框。 如图 3 中所示。 要标定铲运斗控制器,选择"铲运斗操纵杆标定 (Bowl Lever Calibration)" (1) 。

  1. ET 屏幕将指导技师在位置 (4) 和 (5) 处进行操作。 这些指导如下所示。

  1. 必须设置车辆停车制动器。

  1. 发动机转速应为 0 RPM。

  1. 在满足初始条件后,选择 ET 屏幕上的"下一步 (NEXT)"按钮。

  1. 松开操纵手柄,使操纵手柄在空档卡销位置。

  1. 选择 ET 屏幕上的"下一步 (NEXT)"按钮。

  1. 将操纵手柄移到铲运斗完全升高位置 (3) 。 在该位置保持铲运斗的同时,按下铰接缓冲装置按钮 (cushion-hitch button)。 然后松开铰接缓冲装置按钮 (cushion-hitch button) (2) 。

  1. 将操纵手柄移到铲运斗完全降下位置 (1) 。 该位置是指过了卡销位置的行程未端。 在该位置保持铲运斗的同时,按下铰接缓冲装置按钮 (cushion-hitch button)。 然后松开铰接缓冲装置按钮 (cushion-hitch button) (2) 。

  1. ET 软件随后会显示一个表明标定状态的屏幕。 如果标定失败,检查有无下面两条信息之一:

    • "标定值太大 (Calibration value too large)"

    • "标定值太小 (Calibration value too low)"

    如果标定不成功,请参阅故障诊断, "操纵手柄标定不成功"。
