(43)This indicator is glowing continuously when the device is working.

It flashes when the equipment is temporarily stopped due to a fault displayed by the indicator (42) or a ON/OFF control cabled at the ”Remote ON/OFF” input (7), or when the equipment is intentionally put to idle mode by the master unit in a multi-inverter parallel system (see chap. chap.6.3.2 - p. 22).

The equipment will restart automatically when the conditions that led to the temporary stoppage have gone away.

(44)This indicator is glowing continuously when the charger is working and has not yet reached his absorption phase.

It flashes twice during the absorption phase and once during the floating phase.

If the smart boost mode has been activated, this indicator goes out temporarily when source backup is required by users (loads).

(45)This indicator is glowing continuously when a n alternative voltage with correct values, either in frequency {1112-1505-1506}, or in voltage {1199} is present at the AC IN input of the device and the current limit set by the user has not been reached. It flashes when the current limit at the input {1107} set by the user has been reached. In this case the charger current is reduced in order to guarantee priority supply to the users (see chap. 6.2.5 p. 19). If the input current is exceeded nevertheless, the Xtender goes back to inverter mode (transfer relay open) and the indicator (42) will keep flashing as long as the user current exceeds the limit value of the input current {1107}.

If the smart boost mode (see chapter 6.2.6 – p.19) is used and the inverter is part of the user supply

– therefore the battery is discharged – the “charge” indicator (44) will be glowing.

(46)This indicator is glowing continuously when an alternative voltage of 230V is present at the equipment output. It flashes when the device is in “load search” mode according to chapter 6.2.2 – p. 16.
