DST4601 brings new concepts in gen-set controller devices: Merging both LED and LCD displays, gives you measures reading easiness of standard panel meter devices alongside the use simplicity,

Thông tin chi tiết

OPERATION

By means of key operated selector switch and push buttons, the following modes can be selected:

OFF/RESET/PROGRAM: engine start inhibition, load is forced to be supplied from the Mains. When the engine is running and the selector switch is turned to the 'OFF' position, the engine shutdown sequence is activated. Reset of all alarms.

PROGRAM is a function which allows to access to all programmable parameters. If the key selector is in OFF position, it is possible to change parameters Enable parameters change (programming)

MANUAL: engine manual START and STOP controls are enabled. The Gen Set protection devices are activated. The starting command is automatically disabled when the engine is running.

AUTOMATIC: DST4601 act as AMF device. Auto-matic start upon Mains failure. The engine start is obtained through a cycle of starting attempts, each followed by a pause.

In case of starting failure, the control board gives an optical signal and forces the Gen Set to shutdown, thus avoiding battery discharge. Upon engine starting, the starter motor is auto-matically disconnected by the electronic control board. Once the rated conditions are reached, the Gen Set is connected to the load. The Gen Set is automatically controlled by the appropriate protection devices. When the Mains return within the normal limits, the Gen Set is automatically disconnected from the load.

The load is then supplied by the Mains and the engine is stopped after an adjustable cooling time.

TEST: Automatic start for testing operations with s af ety protections enabled. Mains/Gen Set changeover is dis abled. U pon Mains failure, the load is immediately supplied by the Gen Set.
