13. Module replacement
13.1 Module replacement
A module must be exchanged, for example to
replace a defective module with an intact module
in your meter and module topology. The module
replacement 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.
1. Remove the corresponding module as described
in Sect. “12. Dismounting” on p. 37.
2. Replace a defective module, for example, with an
intact one (see Sect. “4. Mounting” on p. 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 mod-
ule (stored in the UMG 801 basic device) to the
intact module.
INFORMATION
Please note before replacing a module! 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.
13.2 Modules - Error cases
As already described in Sect. “5.4.3 Module identi-
fication - LED blink interval” on p. 27, the module
has 4 LEDs.
Tx
Rx
P
E
In the event of an error, the red LED (E) of the module
blinks during operation at an interval of
0.5 s .
After the definition of the error state there is a pause
of
2 s and the blink interval starts again from the
beginning (repetition loop).
The number of blinks indicates the following error
states:
Number of
blinks
Error state
0 No error - normal operation.
1
Waiting for termination of the start pulse for
the termination.
2 Waiting for response of the following module.
3 Waiting for start of addressing pulse
4 Waiting for the end of the addressing pulse.
5 Termination failed.
10
Application could not be started, module is still
in the bootloader.
Tab.: Allocation of blink intervals to error state
Proceed as follows in the event of a module error:
1. Restart your meter and module topology (ba-
sic device: Menu > Configuration > System >
Restart).
2. Check the connections and the fit of the devic-
es, modules and components of your meter and
module topology while complying with the safety
rules!
WARNING
Risk of injury due to electrical current and voltage!
Severe bodily injury or death can result! Therefore
please abide by the following:
· Do not touch bare, stripped wires or device in-
puts that are dangerous to touch on the devic-
es, components and modules.
· Switch off your installation before commenc-
ing work! Secure it against being switched on!
Check to be sure it is de-energized! Ground and
short circuit! Cover or block off adjacent live
parts!
