The Model 555 is an Automatic Mains Failure Control Module, with comprehensive instrumentation and load control option. 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.

It is also possible to monitor the operation of the system either locally or remotely (Optional: Remote Communications output version only). Access to the module is restricted by PIN number.

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.

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

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.
