reached during a predetermined time {1256}
The voltage of the battery is automatically compensated according to the instantaneous
battery current the same way as it is done for compensation of LVD (see chapter 6.2.8 –
p.24) if parameter {1191} is activated.
Contact no. 2 (AUX2) : alarm contact by default. It is deactivated when the inverter is out of service
or is working at reduced performance, either because of manual control or if there is an
operational fault such as overload, undervoltage of the battery, overtemperature, etc.
The functions of the two auxiliary contracts can be modified and programmed variously with the
help of the RCC-02/03 control.
If the operator or installer requires different behaviour for the auxiliary contacts, they are both freely
and individually programmable depending on the battery voltage and the inverter status and the
internal clock.
The intelligent programming of the auxiliary contacts allows many applications to be considered
such as:
Automatic startup of the generator (two or three wires)
Automatic load shedding of the inverter (2 sequences)
Global or individual alarm
Automatic disconnection (load shedding) of the source

6.2.11 The real time clock

The Xtender has a real time clock that allows the functioning of the auxiliary contacts to be
managed, in particular. This clock must be adjusted via the use of the RCC-02/03 remote control.

6.2.12 Entry command (Remote control on/off)

This function is available as a standard on XTH
series. On XTM range, the function is available as
an option thru the remote command module
RCM-10 (see chap.6.4.3 p..28.
This entry is to drive one or more function that
you can choose thru programming of the RCC-
02/03. the function is activated or by opening
/closing a potential free contact or by applying
a voltage (Max. 60 V eff./30mA)
across the terminal block. The jumper (6) must be
correctly positioned according to the chosen variant as described in the figure opposite.
In multi-unit configurations (see below) the chosen functionality must be the same in every unit in
the system. Only one unit can be wired to apply the function to every Xtender in the system. If the
entry command is used as an emergency stop, (all functions halted) it has to be wired on the unit
with the highest serial number (master).

ULTI UNIT CONFIGURATIONS
Several Xtenders can be used in the same system, either to create a three-phase system or to
increase the power output of a single or two phases. The implementation of this configuration
requires particular precautions and it must be installed and commissioned by qualified personnal
only.
