我厂造粒装置粉末计量进料器自动称重控制系统主机采用的是意大利CIFA公司生产的PPM01-18型控制器.它是一个以微处理机为基础的智能控制器,具有过程调节和逻辑判断的功能,用于控制和调节以称重法工作的分批配料装置,具有工作可靠和性能稳定的特点.但是,该控制器在设计上存在先天不足,装置在运行过程中不能进行手动/自动无扰动切换.原设计的手动/自动切换开关只能在开机之前设定好,这无疑给操作带来很大不便.在过程出现大幅度波动的情况下,操作人员毫无办法.因为这个原因,使得
I granulation plant powder metering feeder automatic weighing control system host is used in Italy CIFA company PPM01-18 type controller.It is a microprocessor-based intelligent controller with process regulation and logic Judging function for controlling and adjusting the batch batching device which works by weighing method has the characteristics of reliable working and stable performance but the controller is inherently deficient in design and the device can not be manually / automatically operated during operation Bumpless switch. The original design of the manual / automatic switch can only be set before starting the boot, which undoubtedly bring great inconvenience to the operation in the process of significant fluctuations in the case, the operator no way .For this reason So
