The configurable Automatic Mains Failure Model 509 allows many of the industry is demanding specifications to be achieved. Variations of the unit offer additional functions such as the RS232 interface for remote monitoring by a volt free relay module, annunciator or building management system.
The 509 is used to start a generator on a mains (utility) failure and transfer the load when the engine is operating criteria have been met. On the restoration of the mains (utility) supply, the engine is returned to standby mode. The operation of the module is via a four-position rotary switch (key-switch option available) mounted on the front panel with STOP, AUTO, MANUAL (Off-load run) and TEST (on-load run) positions.
Once activated, the 509 module carries out all the start and stop procedures of the engine, indicating operational status and fault conditions, and automatically shutting down the engine, giving true first up fault condition of the engine failure. The information is displayed on an illuminated Liquid Crystal Display on the front panel. Text and selective operational sequences can be altered using the 801 Calibration Unit. Adjustable parameters are displayed on the screen when the CONFIGURATION mode is activated.
