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.
VBus
®
/ USB interface adaptor
The new VBus
®
/ USB interface adaptor is the interface between the controller and a
personal computer. With its standard mini-USB port it enables a fast transmission of
system data via the VBus
®
for processing, visualizing and archiving. A full version of the
ServiceCenter software is included.
VBus
®
/ PWM interface adaptor
The VBus
®
/ PWM interface adaptor is used for the speed control of a pump via a PWM or
0-10 V signal. Via the VBus
®
, the adaptor receives information from the controller about the
necessary pump speed. The speed is converted into a PWM or direct voltage signal and put
out to the corresponding terminals.
AM1 Alarm module
The AM1 alarm module is designed to signal system failures. It is to be connected to the
VBus
®
of the controller and issues an optical signal via a red LED if a failure has occurred.
The AM1 also has a dry contact relay output, which can e. g. be connected to a building
management system (BMS). Thus, a collective error message can be issued in the case of a
system failure.
VBus
®
/ LAN interface adaptor
The VBus
®
/ LAN interface adaptor is designed for the direct connection of the controller
to a PC network or router. It enables easy access to the controller via the local network of
the owner. Thus, controller access and data charting can be effected from every workstation
of the network. A full version of the ServiceCenter software is included.
