The configurable Automatic Mains Failure Model 509 allows many of the industry’s demanding
specifications to be acheived. 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’s
operating criteria has been met. On restoration of the mains (utility) supply, the engine is returned to
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.
Access to the critical operational sequences and timers, for use by restricted personnel, are barred by a
security code. Relay outputs are provided for Fuel Solenoid Output, Start Output, Alarm Output and one configurable output. The configurable relay is usually configured as pre-heat, however this
function can be changed to activate on a range of 6 different functions, conditions or alarms. The relays
supply positive plant supply out.
Configurable inputs are available for Low Oil Pressure or High Engine Temperature, allowing the module to function with N/O or N/C switches. Three fully configurable auxiliary inputs are provided to give protection expansion. These can be selected to be indication, warning or shutdown inputs either immediate or held off during start up. Alternatively they may be configured to provide additional control features to the module.
The 500 series modules have been designed for front panel mounting. The module is fitted into the panel cutout with the fixing clips removed. These are then fitted from the rear. Connection is via locking plug and socket connectors.
