Functioning description:
Working state real
After all the machine on real-time parameters can be displayed on the interface, such as temperature, pressure, pumping and mixing speed, security levels, alarm conditions and other procedures set by the parameters must be displayed.
Formula design program
The major setting and save the formula interface ( depth, temperature, pressure, etc). For each formula can be set and save 10 subroutine, these subroutines can cast the first one near the selector out directly.
Calibration interface
This interface is mainly used to automatically correct out of three different charge, by a balancer to determine quality.
The software also include some other systems, such as casting machine maintenance control, work time, data statistics and alarm records. Computer software must pass a set of passwords or keys in order to start, this can guarantee the authorized person is different for different levels of machine control.
