需要使用 OEM 油气井用变速箱控制来支持 12 伏和 24 伏系统。 变速箱固件取决于系统电压，因此必须相应更换起动继电器和变速箱电磁阀。
ECM 根据输入 ECM 的信息及存储器中的信息做出决定。 然后，ECM 通过输出发出相应响应。 机具 ECM 的输入和输出与机器线束相连。 使用触点接头 "J1" 和 "J2"。
机器有几个输入设备。 输入设备通知 ECM 机器的操作状态。 机器的输入来自开关和传感器。 各开关可向机具 ECM 输入提供开路、接地或蓄电池正极信号。 传感器不断向 ECM 提供变化信号。
机具 ECM 通过输出发出电气信号，对决定做出响应。 输出可以产生一个动作或者向 ECM 提供信息。
