DSE5120

Auto Mains (Utility) Failure Control Module

Features

The DSE5120 is an Automatic Mains (Utility) Failure Contro lModule designed to automatically start and stop diesel and gas generating sets that include non electronic engines.  The module also provides
excellent engine monitoring and protection features.

The module has the ability to monitor under speed, over speed, charge failure, emergency stop, low oil pressure, high engine temperature, fail to start, fail to stop and loss of the speed sensing signal. The module displays fault conditions on the LCD display and via the LED indicators on the front.

The DSE5120 also has the ability tomonitor a mains (utility) supply. Upon detection of a mains (utility) failure the module automatically starts the generating set. Once the mains power has been restored it instructs the generating set to stop.

OPERATION

The modules are operated using the front STOP, AUTO and MANUAL push buttons. The DSE5120 also
includes a TEST button. An additional push button on both modules allows the user to scroll through the LCD instrumentation display.

CONFIGURATION

The modules can be configured using the front panel buttons or the DSE810 interface and PC software.
