4.1.2 Remote Start/Stop (2 Wire) To use the Remote Start/Stop Mode of the controller, the Mains monitoring should be disabled first before using the Remote Start/Stop feature. In this mode, the genset can be commanded to start and stop by activating/deactivating the preconfigured Remote Start/Stop input (active low) in a continuous state.

Alarms An alarm condition occurs when a preconfigured parameter is outside of a pre-set level. On initiation of an alarm, the Alarm LED will start blinking and the fault output pin will be activated if configured. The controller will display the name of the alarms along with a count on the ALARMS screen and the nature of alarm on the ENGINE STATUS screen.

Alarms Causes alarm. Clears at the next successful exercise cycle Troubleshooting WARNING Autostart Hazard. With the battery connected the generator may crank and start without warn- ing, resulting in death or serious injury. Before servicing, stop the generator and disconnect the negative (-) cable at the battery.
