OIL PRESSURE AND MOTOR PROTECTION MODULE 油压和电机保护模块 SUMMARY/ 目录 Introduction / 简介 ? 03 Technical characteristic and codes/ 技术特性和代码 ? 04 Fitting of the D.P.S. sensor/DPS传感器装配 ? 06 Electrical connection/电气接线 ? 09 Introduction 简介 All semi-hermetic compressors, from the model K1500CS to the model K7500CC, are fitted with the electronic module CPM. Officine Mario Dorin have developed a new model, called CPM3, which is perfectly interchangeable with previous model CPM2 (seeBT005/99; new model is more reliable and its cabling is easier. It is interchangeable with relay INT69TM. The CPM3 provides a total protection of the compressor electrical part (protection with termistor and the mechanical part (protection against insufficient oil pressure. In order to obtain the two protections it is necessary to connect the CPM3 following the instructions given below ( for thermistor protection and also the differential pressure sensor DPS ( oil pressure protection which is optional . 从 K1500CS 到 K7500CC 的所有型号半封闭压缩机配置 CPM 电子模块。 DORIN 公司开发了一种 CPM3的新型号,可与以前的 CPM2(见 BT005/99 完全互换。新型号更可靠,接线更容易。它与 INT69TM 继电器互换。 CPM3为压缩机电气元件(带热敏电阻器保护和机械元件(油压不足保护提供完全保护。为获得这 2种保护,有必要按以下说明连接 CPM3(热敏电阻器保护和备选 DPS 差动压力传感器 (油压保护 Technical characteristics技术特性 Advantages The principal advantage, in comparison with traditional mechanical oil pressure switch, is that the capillary (and the risk of leak is substituted by an electrical cable. Moreover there is the possibility to monitor the oil Pressure without having to connect pressure lines to the oil pump or the body of the Compressor. The Differential Pressure Sensor (DPS is fitted directly on the oil pump and transmits a signal corresponding to the effective pressure value of the differential oil pressure to the electronic module via an electrical cable. All running parameters of CPM3 are already input at the factory and unchangeable. It is sufficient to put the DPS sensor on the body of the oil pump and connect it to the electronic module CPM3. The new
