SMA CLUSTER CONTROLLER - Manual (Page 44)

7 Device Configuration
7.1 Setting the Characteristic Curve of the Irradiation
Sensor
If you have connected an irradiation sensor to the Cluster Controller, you must also set the
characteristic curve of the irradiation sensor via the user interface of the Cluster Controller. As a
result, the current signals in mA provided by the irradiation sensor are converted by the
Cluster Controller into the proportional irradiation values in W/m
2 and displayed.
Requirement:
☐ An irradiation sensor must be connected to the Cluster Controller (see the Cluster Controller
installation manual).
Procedure:
1. Select the Cluster Controller in the system tree and select the menu Settings in the device
menu.
2. Select the parameter group Meteorology > Environment > Irradiation sensor >
Characteristic curve.
3. Select [Edit].
4. Set the characteristic curve depending on the connected irradiation sensor (see manual from
manufacturer).
5. Select [Save].
7.2 Parameter Settings
7.2.1 Setting Parameters for a Device Class
A device class refers to all devices of the same type. You can configure all the devices in a device
class simultaneously. However, it is not possible to configure different device classes at the same
time. Therefore, save the changes made to one device class before processing another device
class.
The parameters that you are able to set for a device class depend on the rights of your user group
(see Section 4.1, page 25).
Procedure:
1. Select the system in the system tree and select the menu Settings in the device menu.
2. Select the parameter group that contains the parameter which is to be configured.
☑ The individual device classes are displayed in brackets after the name of the parameter
group, e.g. Device (Communication products). It may take a moment for all the data
to be read out from the devices.
3. Select [Edit] in the parameter group of the desired device class.
