Connecting The Temperature Sensor (Bts-01); Auxiliary Relay Module Arm-02; Parallel Connection Cable - Studer VarioString User Manual

9.2.1 Connecting the temperature sensor (BTS-01)

The optional temperature sensor BTS-01 is supplied with
a 5m cable fitted with RJ11/6-type plugs. It may be
connected or disconnected at any time (even when
the device is operating) using the corresponding
socket (6) marked "BTS & ARM02" on the VarioString.
Plug the connector into the socket (6) until it clicks in.
The temperature sensor case may simply be stuck
onto the battery or directly next to it. The temperature
sensor is automatically recognised and the correction
of the voltage thresholds applied immediately. If a BSP
battery probe next to the battery is used, a BTS-01 is
not necessary. The BSP module is fitted with a
temperature sensor. If both elements (BTS-01 and BSP)
are present, only the BTS-01 is taken into account to
correct the battery temperature.
9.3 A ARM-02
UXILIARY RELAY MODULE
This external module is mounted on DIN rail and connected to the same connector as the battery
temperature sensor (6) by using a 5m cable supplied with the accessory. If the connector (6) 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. 8.4.3.1.
9.4 P
ARALLEL CONNECTION CABLE
This cable allows for the quick and secure connection of two PV strings in parallel.
