Extended functions {1489}

Generator startup {1490}

The two contacts may be combined in order to automatically start up a generator equiped with an electric starter. In this case the two contacts are dedicated to this function.

Auxiliary contact 1 serves as an operational contact and auxiliary contact 2 as a startup contact.

The startup condition of the generator must be programmed with the configurations of auxiliary contact 1. The startup is carried out by first activating the operational contact and then activating the startup contact. The latter engages several times, if necessary, to start up the motor. If a voltage appears at the terminals of AC In, the startup contact is released.

B.Duration between attempts {1494}

C.Number of attempts {1493}

Generator startup {1491}

Activates the combination of the two auxiliary contacts for the generator start and the mana- gement of the start impulses.

Duration of starter impulse {1492}

With this configuration you can adjust the time at which the startup contact is activated.

Number of startup attempts {1493}

The startup contact is activated a limited number of times in order to protect the starter if the generator has a fault. Once the maximum number of startups has been reached, the operational contact is also deactivated. For a new attempt to be made the condition that generated the startup must disappear and reappear.

Duration between the starter attempts {1494}

This configuration determines the duration between the startup attempts. It also determines the duration between the activation of the operational contact and the first attempt at restarting.

Multi Xtender {1282}

This section allows setting the operating possibilities of systems with several Xtenders. Either parallel or 3-phase.

3-phase integral mode {1283}

If you activate this parameter, the system will work in order to have either a 3-phase output, or no output voltage. For instance in case of one phase overload, if the integral mode is activated, the cut of this phase will lead to the cut of all phases.
