(3) 停车制动器开关
(4) 小键盘

行走操纵杆 (2) 位于右控制台上。 行走操纵杆通过 CAN 通信线路向机器 ECM 提供输入信号。 机器 ECM 将该输入信号用作停车制动器控制的参数之一。 机器 ECM 还利用来自行走操纵杆的输入信号确定所需的转速和方向。

行走操纵杆 (2) 的中间位置为空档位置。 如果行走操纵杆的位置不适于当前的机器状况,显示屏 (1) 上出现错误消息。

当行走操纵杆从中心位置移向机器前面时,所需行驶方向设为前进。 当行走操纵杆从中心位置移向机器后面时,所需行驶方向设为后退。 操作员将控制杆移离中心或空档位置越远,所需行驶速度越大。

注: 操作台朝后时,倒车警报和转向信号识别新的机器前方。 在这种情况下,这些部件相应运行。

停车制动器开关 (3) 和键盘 (4) 位于右控制台上。 机器 ECM 直接监控来自停车制动器开关的输入。 小键盘通过 CAN 通信线路与机器 ECM 通信。

停车制动器开关 (3) 是一个具有两个位置的摇臂开关。 当向下推开关前部时,停车制动器开关置于接通位置。 当向下推开关的后方时,开关置于断开位置。 当停车制动器开关处于接通位置时,停车制动器接合。

ECM 将来自停车制动器开关 (3) 的输入信号用作停车制动器电磁阀的控制参数之一。

小键盘
(5) 行驶速度指示器
(6) 行驶模式指示器
(7) 增速开关
(8) 降速开关
(9) 行驶模式开关

右控制台上的键盘包含可使操作员控制机器速度和行驶模式的开关。

增速开关 (7) 和降速开关 (8) 换算所需机器速度。 行驶速度指示器 (5) 向操作员指示当前所选换算系数。 换算系数范围从零到 100%。 当换算系数为零时,所有行驶速度指示器均不点亮。 当换算系数为 100% 时,所有指示灯点亮。 每个指示灯代表一个约 14% 的换算系数变化。

每次操作员驱动速度开关 (7) 或 (8) 时,显示屏上都会弹出一个窗口。 弹出窗口显示当前所选换算系数。 机器 ECM 在存储器中存储最后激活的换算系数。 发动机起动开关转到断开位置后,机器电子控制系统利用最后选择的换算系数起动。

行驶模式开关 (9) 允许操作员将行驶模式从低更改为高。 每次按下开关,机器 ECM 都将触发行驶模式一次。
