1 INTRODUCTION
The
DSE 5520
Module, has been designed to allow the OEM to meet demand for increased
capability within the industry. It has been primarily designed to allow the user to start and stop the
generator and if required, transfer the load to the generator either manually or automatically, or in
the event of the module detecting a mains failure. The user also has facility to view all the system
operating parameters via the LCD display.
Utilising the inbuilt synchronising, volts matching and paralleling functions, the 5520 can also be
used to parallel with the mains supply for no break return, peak lopping or power export
fucntionality.
The
DSE 5520
module monitors the incoming AC mains supply for under or over voltage / under
or over frequency and instructs the generating set to start and to supply the load.
The
DSE 5520
module also monitors the engine, indicating the operational status and fault
conditions; automatically shutting down the engine and giving a true first-up fault condition of an
engine failure by a flashing COMMON ALARM LED. Exact failure mode information is indicated
by the LCD display on the front panel.
The powerful Micro-processor contained within the module allows for a range of enhanced
features to be incorporated as standard;
Full Multi-lingual LCD display (including non-western character fonts).
True RMS voltage monitoring.
Power measurement instrumentation.
Communications capability (RS485 or RS232 including GSM/SMS functions)
Check Sync capability
Automatic Sync capability
Load control capability
Fully configurable inputs for use as alarms or a range of different functions.
Extensive range of output functions using built in relay outputs or relay expansion available.
SAE J1939 instrumentation and diagnostics when connected to a compatible J1939 engine
controller.
