The Real Time Clock; Description Of The Variostring Parameters; Convention; Parameter Access Level - Studer VarioString User Manual

The parameter values can be modified using the RCC and are stored and applied by the VarioString.
When the remote control RCC is connected to the VarioString by the communication bus
it is possible that the software versions are not compatible. It is highly recommended to
update the software of all components in the system in order to guarantee all
functionalities. Therefore, before starting the setup of the device, download the latest
software version from our website: www.studer-innotec.com on an SD card. Follow the
instructions in the RCC manual for a successful installation.

8.3.1 The real time clock

The VarioString features a real time clock that allows among others to have a correct date and hour
for the RCC records. This clock must be set using the remote control RCC-02/03. Thanks to an internal
battery, this setting is retained even when the equipment is disconnected from its voltage source
(battery or PV).

ESCRIPTION OF THE
The parameters of the VarioString can be modified in the menu "VarioString MPPT setting" of the RCC
remote control.
This menu allows accessing the following 4 under-menus:
BASIC SETTINGS: where the most common parameters to be set when commissioning are found.
BATTERY MANAGEMENT AND CYCLE: where all the parameters can be set, defining in detail the
battery cycle during all its phases.
SYSTEM MENU: gathering a few parameters that are not directly related to the battery cycle, such as
backing up and restoring the system, resetting, monitoring setting, etc.
AUXILIARY CONTACTS: where the parameters related to the auxiliary relays (optional accessory ARM-
02) can be set.

8.4.1 Convention

Functions and values of the parameters mentioned in this manual are described in this chapter. Each
parameter is defined by a short description, a number {xxxxx} followed by its value and unit by default
(xxxxx). The type of parameter (menu, signal) replaces the value between brackets when this latter
does not exist. The RCC menus are also identified by a name and a number {xxxxx} that can be
found, as per the parameter number, on the top right-hand corner of the RCC screen.

8.4.2 Parameter access level

All the parameters described hereafter are accessible through 2 different access levels. In factory
configuration, only a few of them are accessible through the "basic menu".
To access all the other menus and parameters, the RCC must be configured at the "Expert" level
following the procedure given in the RCC manual, chapter "User level".
The parameters in grey are accessible only by qualified personnel.
