Patchable for connection router to Main Control

The entire system has to be electronically controlled by microprocessors/ computer. The main control unit, which controls the sending process and the compressor unit, supervises all system components. The sending process has to be indicated on display devices. The device also has to provide information to find the cause of a system malfunction. Customer-specific data such as the system’s layout, target numbers, target names, arrival signals, priority and special functions must be selectable on site without change or external reprogramming of memory devices. A integrated uninterrupted power supply must provide the requested system back up time to paste all date before shutting down the system, so after power source is providing energy again an automatic system start will occur and the system status will get back in the operation mode as before. Chosen targets at stored containers must be kept in the memory to proceed them automatically after power failure restart.

All components of the pneumatic tube conveyor are constantly monitored; the operating software has to be based on action reaction control for any device. The status of each device can be checked by the master control unit. A test program must be included to automatically check, move and supervise all of the system’s devices, or specific selected devices, by access via service code from the Station control panel.

During both normal operation and testing, all devices inform the master control unit that the selected functional position has been reached. This ensures that this position truly has been reached. The system is designed in such a way that it does not allow the unobserved pivoting of devices. The system has to come with an efficient fault-clearance program that automatically recognizes operating errors, power failures, time-out errors and other system errors. It also allows the system to continue functioning; there is no need for the operating personnel to intervene.
