There are two buttons:
The multicolour LED gives the following indications:
If the blinking from the LED is disturbing during use, it can on newer hardware (Pow-K layout 1.6.x and newer) be deactivated in the settings:
The board can be installed to replace the original card of a Kamstrup HAN-NVE module.
This is a good solution for users in Norway that receive the HAN-NVE module from the grid company, or have it pre-installed on the meter:
If the HAN-NVE module is installed in the meter: Pull it out horizontally.
In some cases this may require using some force. There is no locking mechanism, the connector is just sometimes a tight fit.
Note: Do not bend or twist, pull it straight out.
Remove the lid, which is released by pressing on each side of the box in the area indicated by red arrow below:
|
Remove the original board, place it in the protective bag the Pow-K was delivered in – and store it safely with the meter.
The card is held in position by four slots: Two in the bottom of the enclosure, two in the lid.
In the enclosure:
In the lid:
Position the Pow-K card in the slots of the lid, ensure it is correctly seated:
Place the enclosure over the board, pull lid and enclosure together until it snaps in place:
Kamstrup Omnipower meters can be configured by the grid company to deliver data in 3 formats:
As the large majority of Kamstrup Omnipower meters are configured as either HAN-NVE or DLMS Push 1, so new Pow-Ks are configured for 2400 baud - and will work out of the box on both configurations.
Important note:
Pow-K will only work on P1-configured meter after doing the following change on the configuration screen:
For more information on the payloads sent by the meter, see Omnipower(R) HAN Interface specification.
Boards with layout version v1.6.1 and newer can read Kamstrup 382M meters.
This is the configuration needed to read data from Kamstrup 382M:
Boards with layout version v1.6.1 and newer can accommodate a user-installed temperature sensor, type Dallas DS18B20. The necessary pullup resistor is installed.
Temperature sensor can be bought from mouser.com, digikey.com or other electronic component outlet.
To activate the temperature sensor, user must change the hardware setting:
