Control System
FEATURES Microprocessor control, with high stability and credibility Monitoring and measuring operational parameters of the mains supply and genset
Digital, intelligent control system allows easier operation.
Indicating operation status, fault conditions, all parameters and alarms Multiple protections; multiple parameters display, like pressure, temp. etc. Manual, automatic and remote work mode selectable Real time clock for time and date display, overall runtime display, 250 log entries Overall power output display
PLC-7420 PLC-7420 is an advanced control module based on micro-processor, containing all necessary functions for protection of the genset and the breaker control. It can monitor the mains supply, breaker control. and automatically start the engine when the mains is abnormal. Accurately measure various operational parameters and display all values and alarms information on the LCD. In addition, the control module can automaticallyshut down the engine and indicate the engine failure.
Integral speed/frequency detecting, telling status of start, rated operation, overspeed etc. Communication with PC via RS485 OR RS232 interface, using MODBUS protocol
