5.2.9 External messages and signals
Alongside the external team power cabling, appropriate signal and message connections between
the team devices have to established.
5.2.10 Sensors and digital outputs
In the Sunny Central it is possible to connect a temperature sensor PT 100 and two further analog
sensors (e.g. pyranometer, reference cell) to the Sunny Central Control panel. The corresponding
connection customer-side possibilities are at the analog inputs Ain 3, Ain 4 and Ain 8. Further
information about the connection and parameterization of analog sensors is contained in the Sunny
Central user manual.
Setting up the signal and message connections between both team devices.
When connecting the signal and message connections between both team devices, it is
obligatory to follow the circuit diagram included in the delivery.
Overtemperature notification from the medium voltage transformer
Specific to the HE devices, it is possible to connect an overtemperature notification from the
medium voltage transformer.
Remote deactivation unit
Special project-dependent installations can optionally be equipped with a remote
deactivation unit in combination with the monitoring of the switching position.
When connecting the remote deactivation unit, it is obligatory to follow the circuit diagram
included in the delivery.
Assignment of analog and digital signals with Sunny Central Control
When connecting the analog sensors and for the digital signals, it is obligatory to follow
the provided circuit diagram. The connection is made at the connection terminals. The
connection for the four-conductor and two-conductor sensor has to be considered and if
necessary essential measuring transformers have to be installed.
