DSE Model 5320 Automatic Mains Failure & Instrumentation System Operators Manual
Part No. 057-014 5320 OPERATING MANUAL ISSUE 5.1 18/06/2007 ADM 5
1 INTRODUCTION
The DSE 5320 automatic mains failure module has been primarily designed to monitor the mains (utility) supply,
starting the generator automatically should it fall out of limits. Transfer of the load is automatic upon a mains supply
failure. If required the generator and can be started and stopped manually, and if required, the user can transfer
the load to the generator either manually (via external push-buttons) or automatically. The user also has the facility
to view all the system operating parameters via the LCD display.
The DSE 5320 module monitors the mains (utility) supply indicating the status of the mains on the module’s
integral LCD display. Additionally the module 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 AUDIBLE ALARM. The exact failure mode is indicated by text messages on the LCD display on
the front panel.
The powerful microprocessor contained within the module allows for a range of complex features to be
incorporated as standard:
• Text based LCD display (supporting multiple languages).
• Voltage, Current and Power monitoring.
• Engine parameter monitoring.
• Fully configurable inputs for use as alarms or a range of different functions.
• Extensive range output functions using built in relay outputs or relay expansion available.
Selective operational sequences, timers and alarm trips can be altered by the customer via a PC using the 5xxx
series configuration software and P810 interface. Additionally, a subset of this information can be adjusted from the
module’s front panel configuration editor.
The module is housed in a robust plastic case for front panel mounting. Connections to the module are via locking
plug and sockets.
