2、0CC, 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 to

3、tal 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 th

4、e 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

5、 (油压保护 Technical characteristics技术特性AdvantagesThe 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 conn

6、ect 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

7、 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 CPM3 module is equipped with two terminals (L that permit to be energized with 230V or 115V supply.Reset :By

8、manually disconnecting the supply LN to the module in case of insufficient oil pressure.Automatic in case of trip by termistors and anti short-cycle. 优点比较传统机械油压开关,其主要优点为毛细管 (和泄漏风险被电线取代。另外,可以监测油压而不用将压力管与油泵或 压缩机机体连接。差动压力传感器(DPS 直接装在油泵上,并 通过电缆将差动油压的相应有效压力值信号传 送到电子模块中。CPM3的所有工作参数均已在工厂输入, 是不可 更改的。只要将 DPS
