10.2 Interface adapters
Interface adapters
VBus
®
/ USB
The new VBus
®
/ USB interface adapter is the inter-
face between the controller and a personal compu-
ter. With its standard mini-USB port it enables a fast
transmission of system data for processing, visualising
and archiving as well as the parametrization of the
controller via the VBus
®
. A full version of the Service-
Center software is included.
VBus ® / PWM
The RESOL VBus
®
/ PWM (0-10 V) interface adapter
enables the speed control of a high-efficiency pump
even without an integrated 0-10 V output on the
system controller. The adapter is installed between
the VBus
®
output of the controller and the 0-10 V
input of the high-efficiency pump, where it transforms
the VBus
®
data packets into a 0-10 V or a PWM signal.
10.3 Visualization modules
Smart Display SD3
The Smart Display is designed for simple connection
to controllers with VBus
®
. It is used for visualising data
issued by the controller: collector temperature, tank
temperature and energy yield of the solar thermal
system. The use of high-efficiency LEDs and filter glass
assures a high optical brilliance and good readability
even in poor visibility conditions and from a larger
distance. An additional power supply is not required.
One module is required per controller.
10.4 DL2 Datalogger
DL2 Datalogger
This additional module enables the acquisition and
storage of large amounts of data (such as measuring
and balance values of the solar system) over a long
period of time. The DL2 can be configured and read-
out with a standard internet browser via its integrated
web interface. For transmission of the data stored in
the internal memory of the DL2 to a PC, an SD card
can be used.
The DL2 is appropriate for all controllers with VBus
® .
It can be connected directly to a PC or router for
remote access and thus enables comfortable system
monitoring for yield monitoring or for diagnostics of
faults.
