Benefits Features

1. Data collection, quantitative control function
2. The true color moving picture display
3. parameter settings (loading capacity, the pump is turned off in advance the amount of shut-off valves in advance the amount of flow multistage operation, etc.)
4. Spill chain, grounding chain, chain stop, power-down protection
5. Remote / local loading conversion
6. Real-time monitoring, alarm function
7. loading records storage, query
8. Communications Networking
9. The system of self-diagnosis function
10. A valve control mode (electromagnetic valve, two valves, regulating valves, electro-hydraulic valve)
11. Extended Function Select (IC card control, touch pad control, full numeric keypad control, PC communication, external display)
12. The control mode selection (control 1 1,1 2,1 Control Control 4)
13. Multi-level permission settings, protection
14. with adaptive automatic error correction function: quantitative error arising after 3 consecutive loading will be automatically memory controller, an automatic correction when the next loading loading parameters to make loading error, tended to go "zero . "
15. scalability, increased control module to meet the actual needs of working conditions
