快速连接器电磁阀电路示意图。

"快速连接器"的功能为操作员提供快速更换附件的方法。 从监视器中的快速连接器菜单选项选择"快速连接器"的锁定或解锁请求。

机器 ECM 利用"快速连接器"电磁阀执行从监视器接收的请求。

ECM 将使快速连接器电磁阀通电,以解锁快速连接器。 ECM 将使快速连接器电磁阀断电,以锁定快速连接器。

通过 CAN 网数据链路接收到监视器发送的快速连接器锁定请求时,ECM 将使快速连接器电磁阀断电。 此时快速连接器锁定。 系统液压压力升高时,将激活 1 级警告事件。 代码保持激活,直到主泵压力开关触点闭合,告知 ECM 快速连接器锁定。 在这段时间,监视器将表明快速连接器闭合。 系统压力达到 6000 kPa (870 psi) 时,触点将闭合。 监视器将显示"快速连接器锁定"信息。

如果主泵压力开关触点在闭合后的 60 秒内断开,将产生并记录激活的 3 级警告事件。 出现该事件时,监视器将显示"快速连接器压力低"信息。

机器运转期间,ECM 将继续监控主泵压力开关的状态。 如果未出现解锁请求,并且开关触点在出现锁定指示后的 60 秒或更长的时间后断开,将产生 2 级警告事件。 监视器将显示"快速连接器压力低"信息。

当 ECM 使电磁阀断电以释放快速连接器系统内的液压压力时,将产生 1 级警告事件,直到主泵压力开关触点断开。 在这段时间,监视器将表明快速连接器断开。 开关触点断开时,ECM 将认为附件解锁。 监视器将显示"快速连接器解锁"信息。 压力低于 6000 kPa (870 psi) 时,主泵压力开关触点将断开。

如果主泵压力开关触点在未收到锁定指令时闭合,将产生 3 级警告事件。 监视器将显示"快速连接器压力高"信息。

快速连接器功能可以通过 Cat ET 配置屏幕安装或卸载。
