Bereich	Beschreibung
A - Info & Configuration	In this section you will find basic information about the device, as well as an overview of the device and its connections. Clicking on the corresponding connections opens a configuration window for the selected connection/channel and the corresponding configuration card in the lower area.
B - Menu bar	You can quickly navigate to the desired configuration card using the tabs for the corresponding main categories and the search field.
Configuration	In the lower area you will see all available tabs depending on the active channel/connection or the selected tab.

There are two possibilities for the device configuration:

Selecting the tabs in the menu bar (area B) opens the corresponding higher-level category and selects the configuration card.
Click directly on the connecting element in the schematic image to navigate to the desired configuration card (example: to configure digital output 1, click directly on the number "1" with the white background above the "Digital outputs" label) (see Overview under point 9)
Note: Click directly on a connection in the schematic image to obtain additional information on the selected element.

Exemplary quick guide for a possible configuration
This is an example, the steps may vary depending on the configuration example.

Configuration steps:

Assign a device name (see table item 1)
Set the current transformer type (see table item 2)
Configure the residual current measurements (see table item 2)
Set the averaging time of the recording (see table, item 3)
Set the digital outputs (see table item 4)
Set the analog outputs (see table item 4)
Synchronize the device time (see table item 6)
Adjust the communication settings (RS-485) to the actual network environment (see table item 6)
Select a test interval to configure the RCM test functions (see table item 6)

"Device configurator" menu

Pos.	Name		Description
1	General	Identification	Name of the device: Enter the freely selectable device name (max. 255 characters). Description of the device: If desired, enter a freely selectable description of the device (max. 255 characters).
2	Measurement	Residual current Click directly on the current channel in the device image, see Overview no. 8	Selection of the · Current channels You can select the current channels individually. Then you can change the names of the channels in the upper area.
2	Measurement		Configuration of the current transformers and the associated residual current measurements Transformer for this channel You can select predefined current transformers from a list. In addition, you can select the item "Transformer parameters via GridVis" and set the following parameters there: Duration of magnetization Duration of demagnetization Duration for secondary current buildup Duration for stabilization Ratio of primary to secondary current Residual current measurement - Global settings You can set global settings for all measurements from this channel. Residual current measurement - Individual settings You can make individual settings for warning and limit values.
3	Recording		You can activate recording and set the averaging time here.
4	Peripherals	Digital outputs Click directly on the digital output in the device image, see Overview no. 9	Here you can select the error and warning states for the two digital outputs (multiple selection possible). You can also set the polarity (normally open or normally closed contact).
4	Peripherals	Analog outputs Click directly on the analog output in the device image, cf. overview no. 10	Here you can set the scaling range of the output current for the two analog outputs.
5	Logic		Not yet available at this time
6	System	Time	Synchronize the Device time by selecting the button "Synchronize device time". This change will take effect when the configuration is transferred to the device.
		Communication	Configure the RS-485 interface with the following parameters Device ID Default setting: 1 Baud rate Possible input: 9600 baud, 19200 baud, 38400 baud, 57600 baud, 115200 baud Default setting: 19200 baud The Modbus mode cannot be changed because the device can only be used as a slave. Note: After the baud rate or device ID has been changed, the device must be restarted manually.
		Testing RCM functions	Here you can set a test interval for the RCM test functions. Possible input: "No test interval...", 1 month, 3 months, 6 months and 12 months.
7	Search configuration		Enter a keyword and you will be taken directly to the corresponding configuration menu.
8	Current channels		See point 2 (Measurement - Current transformers - Current channels)
9	Digital outputs		See point 4 (Peripherals - Digital output)
10	Analog outputs		See point 4 (Peripherals - Analog output)
11	RS-485	Interface	See point 6 (System - Communication)
12	Diskette icon		Transfer configuration to the device
13	Device configurator		In the drop-down menu of the device configurator, select Transfer configuration to device Transfer configuration to multiple devices Load configuration from device Standard factory setting Create backup (specifying a file name allows you to save a backup of the device configuration locally) Restore backup (selecting a file allows you to restore a backup of the device configuration) When transferring to several devices, the parameters that can only be assigned once in the system are not selectable.
