Control System DSE7320 (DETAILED in INSTRUCTION)

DSE7320 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 are abnormal. Accurately measure various operational parameters and display all values and alarms information on the
LCD. In addition, the control module can automatically shut down the engine and indicate the engine failure.
FEATURES
 Microprocessor control, with high stability and credibility.
 Monitoring and measuring operational parameters of the mains supply and genset.
 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.
 Integral speed/frequency detecting, telling status of start, rated operation, overspeed etc.
 Communication with PC via RS485 OR RS232 interface, using MODBUS protocol.

Soundproof Enclosure Specification

FDK silent generator is designed by professional acoustic engineers based on years of experience. Now we can make the noise
of the generator less than 80-85dB(A) at 1m, or 70-75dB(A) at 7m, 60-65dB(A) at 15m.
FEATURES
 Multi-way air intake and exhaust guarantee the power performance of the generator.
 Large-scale impedance combined type silencer effectively reduce noise of the generator.
 Internal high performance rubber damper and flexible materials reduce vibration.
 Base mounted fuel tank supports the generator running for 8 hours.

ISO9001:2008 FDK reserves the right to change the specifications and designs without noice.
