14.2 Exchanging an 800-CT8-A module
A module must be exchanged, for example to
replace a defective module with an intact module
in your meter and module topology. The module
exchange of a 800-CT8-A is carried out in the
GridVis® software.
On the basic device (UMG 801), you can detect a
defective module of your meter and module topology
in the "Configuration" display. The defective module
is missing in the "Configuration" display.
To exchange a module, proceed as follows:
1. Proceed with a module exchange as described
in chapter „14. Dismounting“ on page 52.
2. Replace a defective module with an intact one,
for example (see chapter „4. Mounting“ on page
18).
3. Supply your meter and module topology (your
system) with voltage.
4. Use the GridVis® software (“Module exchange”
function) to transfer data from a defective
module (stored in the UMG 801 basic device) to
the intact module.
Modules 800-CT8-A | 800-CON
INFORMATION
Before exchanging a module, note that the "Module
exchange" function in the GridVis® software overwrites
data records of exchanged modules in the memory of
the UMG 801 basic device!
A description of the module exchange in the GridVis®
software can be found in the online help or the tutorials
for the software.
Instead of the GridVis® software, you can also use a
generic OPC UA client to exchange modules.
