在版本10_055中引入了旁路功能。通常不使用；然而，它可以设置在两种不同的ent模式中，即模式1和模式2。旁路功能需要一个额外的远程I/O（客舱I/O）。

控制系统模块DARA之后的第 一个客舱I/O具有以下I/O列表：

DO 1：关闭旁路接触器KA（向上，沿A方向行驶）

DO 2：关闭旁路接触器KB（下部超同步，沿B方向行驶）

DO 3：打开机械。制动器1，下降后可能需要它来停止重载

DO 4：打开机械。制动器2，下降后可能需要它来停止重载

控制系统模块DARA之后的第二个座舱I/O连接到主开关，是可选的。

然而，实际上必须用于旁路模式2，重旁路，因为该模式被用作宏和宏选择需要主开关的Cabin I/O。

旁路模式1用于减少电气室或自由隔间内的损耗。

The bypass feature was introduced in version 10_055. Not usually used; However, it can be set in two different ent modes, mode 1 and Mode 2. The bypass function requires an additional remote I/O (cabin I/O).

The first cabin I/O after the control system module DARA has the following I/O list:

DO 1: Turn off bypass contactor KA (up, drive in direction A)

DO 2: Turn off the bypass contactor KB (the lower part is super synchronized and travel in direction B)

DO 3: Turn on the machine. Brake 1, which may be needed to stop heavy loading after dropping

DO 4: Turn on the machine. Brake 2, after dropping it may be needed to stop the heavy load

A second cockpit I/O after the control system module DARA is connected to the main switch and is optional.

However, it must actually be used for bypass mode 2, heavy bypass, as this mode is used as a macro and macro to select the Cabin I/O that requires a master switch.

Bypass mode 1 is used to reduce losses in electrical chambers or free compartments.
