EMCP4.2B Caterpillar


ECM Connections

Usage:

C3.4B CF6
下图是发电机组电子控制模块 (ECM) 的简化电气示意图。 该示意图并不显示所有可能的线束接头。

EMCP 4 在控制器背面有一个 70 针接头。 并非所有 70 个触针都会使用。 图示指示每个版本的控制器使用的触针。 图示还为每个版本的控制器使用的每个触针提供接线连接。

用于机油压力的模拟输入 1,以及用于冷却液温度的模拟输入 2 将不会用于电子单体喷射 (EUI) 发动机的这些目的。 冷却液温度传感器和机油压力传感器将连接到采用公用发动机接口的 EUI 发动机的发动机 ECM。 EMCP 4 将通过 CAN 数据链路从发动机 ECM 获取传感器数据。

用于离散输入的连接将显示有连接到蓄电池负极的常开触点。 离散输入也可以通过常闭触点连接到蓄电池负极。 为执行连接,输入的激活状态将需要设置为"高激活"。
