DSE557

Auto Mains (Utility) Failure and Mains (Utility) Parallel Controller

Features

The Model 557 is an Automatic Mains Failure Control Module, with comprehensive instrumentation and load control features. The module is used to monitor a mains supply and automatically start and stop the engine. It indicates the operational status and fault conditions, automatically shutting down the engine and indicating engine failure by means of an LCD display, and flashing LED on the front
panel.

Selected operational sequences, timers and alarms can be altered by the customer. Alterations to the system are made using the 810 interface and a PC. This interface also provides real time
diagnostic facilities.

Operation of the module is via pushbutton controls (with security locking facility) mounted on the front panel with STOP/RESET, AUTO, TEST, MANUAL and START functions. The first four pushbuttons feature LED „selected‟ indications. Further pushbuttons provide MUTE/LAMP TEST, LCD PAGE and DISPLAY SCROLL functions.

The module features 32-Bit Microprocessor control and a comprehensive list of timers and pre-configured sequences. User configurable expansion facilities are also provided.

The 500 series modules have been designed for front panel mounting.  The module is fitted into the cut-out
with the fixing clips removed. These are then fitted from the rear. Connection is via locking plug and socket connectors.
