Quando si ripristina la condizione di attivazione, l'unità viene rimessa in stand-by con un ritardo di 30 secondi non modificabili.

L'unità "Master" è sempre quella dopo l’unità in stand-by. Nel caso compaia uno degli allarmi AL01, AL02, AL21, AL22, AL36 sull'unità "Master" o venga disattivata tramite il tasto on/ off o dall'abilitazione esterna, essa viene posta automatica- mente come "Slave" e la successiva come "Master".

Esempio di rotazione:

Supponiamo 4 unità collegate in rete LAN con abilitata la funzione "Change Over" con tempo di rotazione di 12 ore. La logica di rotazione per le prime 60 ore sarà la seguente:

When the activation condition is reset, the unit is put in stand by with 30 seconds delay (fixed time).

The “Master” unit always follows the one in stand by.

In case any of the following alarms occur on “Master” unit: AL01, AL02, AL21, AL22, AL36, or it is deactivate by on/off switch or external enabling, it becomes automatically as “Slave” unit, while the following one as “Master”.

Rotation example:

Supposing 4 units in LAN connection with "Change over" function and a rotation time of 12 hours.

The rotation logic for the first 60 hours will be the following:

RETE LAN CON FUNZIONE CHRONO

La rete LAN non trasmette i dati di impostazione della funzione Chrono alle altre unità connesse in rete, è quindi necessario provvedere all'impostazione di tutti i parametri quali data, ora corrente e fasce orarie, su tutte le unità connesse alla rete come indicato nel capitolo "Funzione Chrono" precedentemente descritto.

RETE LAN CON FUNZIONE COMBINATA CHRONO / CHANGE OVER

E' possibile che le unità presenti nella rete LAN abbiano le funzioni "Chrono" e "Change Over" abilitate.

In questo caso è la funzione Chrono che prevale sulla funzione "Change Over".

Infatti solo se l'unità è abilitata al funzionamento dalla funzione "Chrono" vengono conteggiate le effettive ore di funzionamento dal "Change Over" e di conseguenza la rotazione delle unità.

LAN NETWORK WITH CHRONO FUNCTION

The LAN network doesn't communicate the CHRONO function parameters to the other units connected to the LAN. It is necessary to manually set all the parameters, such as: date, current time and timezone, on all the units connected to the LAN, as indicated in "Chrono function" previously described.

LAN NETWORK WITH COMBINED CHRONO /CHANGE OVER FUNCTIONS

It is possible that all units connected to the LAN network have activated at the same time the "Chrono" and the "Change over" functions.

In this case the "Chrono" function is dominant on the "Change over" function. In fact, the real working hours of the "Change over" and consequently units rotation, are enabled only if the unit is enabled for running by the "Chrono" function.
