DLM screen – INCH Core Load Guard
- Landis+Gyr – EV Editor 1
This topic describes Dynamic load management screen when:
DLM is enabled,
the INCH Core Load Guard is selected as a metering device for DLM to function, and
the INCH Core Load Guard is directly connected (wired or wireless) to the charging station.
Possible scenarios of the DLM screen depending on the measurement source:
DLM screen – INCH Core Load Guard with CTs as the measurement source
1 – INCH Core charging station
2 – INCH Core Load Guard – wireless connected to the charging station
3 – CTs (current transformers) as the measurement source for DLM – wired connected to the INCH Core Load Guard
The following screen is an example that may vary depending on other settings on the screen.
An edit icon is displayed next to the value only if you have permission to modify it; otherwise, the value is read-only.
1 – Toggle to enable/disable the dynamic load management (DLM) functionality.
When the DLM functionality is enabled, additional options appear below; when disabled, the options are hidden.
2 – Core Load Guard is selected as the type of metering device for the DLM functionality.
3 – Tap to open a step-by-step guide to replace your Load Guard. In the guide, swipe left/right between the guide screens.
4 – State of your connection to the Load Guard and its detailed description. Possible statuses:
– Connected
– No connection
– Authentication failed
– Connection lost
– Update in progress
5 – Serial number of the Load Guard
6 – Select a measurement source, from which the charging station receives data via the Load Guard:
– CTs (current transformers)
– External meter
7 – Real-time measurements retrieved from the connected Load Guard, sourced from CTs or the external meter.
8 – Phase limits section displays maximum current limitations for the DLM.

– External meter
For more information, refer to the DLM functionality description of the INCH Core charging station.
7 – Select a type of the meter that is connected to the Load Guard via the RS-485 communication interface.
8 – Set/View the communication connection type between the external electricity meter and the Load Guard, using one of the following communication methods supported by the meter:
– RS-485 – the meter connected to the Load Guard via RS-485
– TIC * – the meter connected to the Load Guard via the TIC port
– P1 * – the meter connected to the Load Guard via the P1 port
*Unplugged for now—stay tuned.
9 – The unique identifier assigned to the meter on the RS-485 communication network, enabling data transmission.
Set/View the Modbus RTU address of the electricity meter, ensuring it is unique within the RS-485 network or bus segment to allow proper communication with connected devices.
10 – Tap Load Guard’s RS-485 Configuration to set/view additional RS‑485 communication configuration for the meter connected to the Load Guard.
11 – State of your connection to the metering device / input and its extended description. Possible statuses:
– Connected – Metering connection is successfully established.
– Connection failed - Check your meter’s connection and configuration.
– Invalid values – Measurements received from the metering device are not valid.
12 – Real-time measurements retrieved from the connected Load Guard, sourced from CTs or the external meter.
13 – Phase limits section displays maximum current limitations for the DLM.
Warning! Before installing, wiring, handling or accessing the charging station in any way, make sure to read, understand and follow the Safety Guidelines.
