Backup Mode Function

Usage:

M315D2 CA4
如果机器 ECM 处于故障模式,可使用备用功能以绕过起动马达的 ECM 控制。

这种情况下的监视器屏幕缺省为备用请求屏幕。 其他功能都不可访问,直到操作员按下中央功能按钮。 按下这个按钮之后,可以使用有限的功能以便操作员操作机器到安全位置。 在此期间,机具锁定电磁阀激活,机具锁定继电器接通。

注: 如果激活了备用开关,液压调节特性将停用。 备用开关停用后,必须按下液压调节瞬时启用开关以重新激活液压调节功能。

注: 对于配备了液压驾驶室提升管系统的机器。 如果操作机器的同时发生了备用事件,则必须使用手动降下阀来降下驾驶室。 该阀位于操作员驾驶室内侧。

当备用功能激活,且钥匙起动开关位于起动位置时,钥匙开关的系统电压将会被引导通过开关触点,以激发起动马达电磁阀。 这种情况将导致起动装置继电器电源保险丝的系统电压激发起动马达电磁阀。

当起动马达电磁阀激发时,直接从蓄电池流出的蓄电池正极电压将转动起动马达并盘车发动机。

当备用功能激活时,大多数机器行驶不需要的机器功能都将停用。 当需要备用功能时,机器 ECM 的软件还会请求变速箱换入第 1 档。
