Peristaltic Pump Remote Control
Peristaltic Pump Remote Control
Nov 09The equipment is intended to enhance the functionality of Cole-Parmer peristaltic pumps. It consists of specially developed hardware unit and PC SW.
The control program is prepared as a sequence of time-steps in the form of Excel Sheet. Each time-step is defined by its duration and the pump through-output in percentage in the range from 00.0% to 100.0%. The maximal number of steps is 255. The total time duration of the program may reach a month. The program is downloaded to the memory of the HW unit through PC USB interface. The HW unit is connected to the pump current loop 4 to 20 mA control input. Once the program is loaded in the HW unit memory it can be started, paused or stopped by pressing respective buttons on the HW unit. The HW unit can work autonomously or in communication with the PC. In the latter case a log file can be recorded in the PC. At any time the operator can check the current status of the program or read the currently loaded program from the unit memory to the PC. During the operation a status of the program is recorded in the non-volatile memory. Thus the system continues the operation correctly after power recovery in case of power black-out.
