Studer Innotec SA
VarioString
User manual V 2.3 47
Functionalities of the RCC-02 and RCC-03 units are equivalent. They differ only in their external
aspect. The RCC-02 is designed for wall mounting whereas the RCC-03 is designed for board
mounting.
Model RCC-03 must be removed from the board to access the SD card slot (during updating, for
example).
Reference number Studer Innotec
Dimensions H x L x l [mm]
Both remote control models are supplied with a 2m cable.
Cables of specific lengths (5m, 20m and 50m) can be ordered.
Item reference: CAB-RJ45-8-xx. The length in metres is specified by xx.
It is possible to connect up to 2 RCC or Xcom to a single VarioString, and up to 3 RCC or Xcom to a
system with several VarioString or Xtender units.
The termination switch of the communication bus "Com. Bus" (9) remains in position T
(terminated) except when both connectors (8) are used. In this case and only in this case,
the switch must be placed in the O (open) position.
10.2 TEMPERATURE SENSOR BTS-01
The operating voltages for lead batteries vary depending on the temperature.
A temperature sensor is optionally available to correct the battery voltage
and guarantee an optimum charge for whatever battery temperature. The
correction factor given by the temperature sensor is set by parameter {14035}.
A single temperature sensor connected to one of the devices is enough in a
system containing several VarioString connected to the same battery bank
(multi-system).
Reference no. for the temperature sensor (including a 5m cable): BTS-01.
Dimensions: H x L x l / / 58 x 51.5 x 22mm.
10.2.1
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 (7) marked “BTS & ARM02” on the VarioString.
Plug the connector into the socket (7) 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.
