UXILIARY RELAY MODULE
ARM-02
This external module is mounted on DIN rail and connected to the same connector as the battery
temperature sensor (7) by using a 5m cable supplied with the accessory. If the connector (7) is
already occupied by the battery temperature sensor BTS, unplug the temperature, plug in the ARM
module in its place and connect the battery temperature sensor to the ARM module.
The auxiliary relay module allows the VarioString to have 2 independent
relays, each of which are fully programmable.
The maximum currents and voltages allowed by these contacts are 16A
for 230Vac and 3A for 50Vdc.
The contact is active when the neighbouring LED is lit up.
The relays are by default deactivated at without programming. To
program the functions on the auxiliary relays, an RCC-02/03 remote
control is necessary. For the parameter description, please see the
programing section of chap. 9.4.3.1

ARALLEL CONNECTION CABLE
This cable allows for the quick and secure connection of two PV strings
in parallel on the VarioString VS-120.
11 EQUIPMENTS COMPATIBLE WITH THE
VARIOSTRING
When making hybrid energy systems, VarioString units are often combined with Xtender
inverter/chargers mentioned below. They then belong to a system where they are interconnected
via the communication bus. The full description of this equipment is available on our website:

TENDER INVERTER
/
CHARGERS
The VarioString is compatible with the entire Xtender range and it allows
making PV/generator or PV/network hybrid systems that are perfectly
coherent. The communication between the Xtender(s) and the
VarioString(s) allow synchronizing the charging cycles of both systems.
When the function is activated using parameter {14036}, the Xtender is
the master of the charge profile and will impose the voltage limits set
by its cycle. It will remain so even if the equipment (Xtender) is turned
off using the ON/OFF button or the charger mode is prohibited.
On the other hand, if the Xtender is turned off using the main ON/OFF
button (de-energized), the VarioString operates with its programmed
values.
The charging current of the equipment add up with no priority. When the Xtender charging
current is for example set to 100A and the VarioString supplies 120A, the battery charging
current may be 220A during the bulk phase.

ATTERY STATUS PROCESSOR
BSP- 500/1200
This module, supplied with a 500 or 1200A shunt, allows measuring the
current, voltage and temperature of the battery. It calculates and
supplies the system with all the information obtained from these
measurements such as the state of charge, time before discharge, history
of the state of charge over 5 days, etc.
