Commissioning and Functional Check

© Landis+Gyr
Before putting the meter into operation the following points must be
checked and corrected if necessary:
1. Has the correct meter (with correct identification number) been
installed at the measuring point of the relevant consumer?
2. Are the thrust screws for the phase and neutral connection tightened
sufficiently?
3. Are the mains inputs and outputs connected correctly? The conductor
from the house connection or from the main fuse must be present at
the input, those of the meter to the consumer at the output.
4. Are the auxiliary inputs (S0, M-Bus) and outputs (relays) connected
correctly?
5. Attach the terminal cover.
6. Move the sliding cover to its normal position.
7. Check the installation as described in section 4.5 "Commissioning and
Functional Check".
The installed meter should be put into service and checked as follows:
1. Insert the main fuse removed before installation. The meter is switched
on.
2. Check the display (no error message) and with no load connected that
the virtual output (creep indicator) is displayed.
3. Connect a load and check that the output LED starts blinking.
4. Check that the meter is measuring correctly. Display indicators and
their functions are described in section 5.1 "Display".
5. Perform the set-up process for the required communication devices
(PLC interface, connected M-Bus devices) as described in section 4.6
"Installation Support for Communication Devices". If PLC concentra-
tors have already been installed on the network and if the new meter
search has been activated in the concentrator, also check the PLC
device communication status in the installation list: PLc100.00 must be
displayed.
PLC concentrators must have been installed
Communication check can be performed only if PLC concentrators have
already been installed on the network.
A PLC concentrator automatically identifies devices operating in its commu-
nication area and adds them to the concentrator's topology in the system
and automatic reading can begin. See concentrator and system documen-
tation for more information.
6. Check that the disconnector is closed (see disconnector state indica-
tion on display), otherwise press disconnector push button.
7. When the meter is successfully installed and PLC device communica-
tion status is OK, seal the terminal cover and move the sliding cover to
its normal position.
