Setting Up Scus - Mennekes ACU Instructions D'installation

4.4 Setting up SCUs

You can skip this set for a pre-configured overall system.
In this case, the connected SCUs are already listed.
For the first-time commissioning of the SCUs, the ACU has
to detect the connected SCUs by applying a one-time search
operation. You can then set the appropriate parameters for
each SCU.
Searching the SCUs
Start the search process as follows:
1. Navigate to "Main Page > Setup > SCU setup".
2. Click on the "Search SCU" button (see chapter "SCU
Administration" on page 10).
If the ID of the SCU is known, you can explicitly search
the SCU using the ID. To do this, tick the box "ID
Search" and enter the ID of the SCU in the box. Click on
the "Search SCU" button to search only for this SCU.
The ID of the SCU can be found e.g. on the plain text
display (in case of Premium / Smart charging column) or
in the service interface (AMTRON).
 The search process starts and runs for approx.
2 minutes. The connected SCUs are then listed.
3. Check whether all connected SCU are listed.
 The ACU has detected and saved all connected SCUs.
If not all connected SCUs are found:
 See chapter "List of malfunctions" on page 31.
