All manipulation with the WS868-PLE-I module during installation is in principle the same, as handling with
any other type of authorized remote reading module for Elster BK-G series gas-meter (e.g. IN-Z61). View of
WS868-PLE-I module installed to gas-meter is displayed in the figure
After module installation make sure the right module is mounted to right gas-meter and fill in the prescribed
documentation.
4.7
Module replacement
When there is necessary to replace the module due to the module failure or due to battery discharging follow this
procedure:
•
check the antifraud seal before dismantling – the antifraud seal damage must be solved according to the
internal rules of the customer/project;
•
remove connecting element (screw, wire...) between the module sealing protrusion and matching protrusion
on the gas-meter;
•
cautiously pull the module out of gas-meter slot;
•
unscrew a screw on the module back cover and remove front lid;
•
switch-off battery by removing of shortening connector from shortening pins and mark the module visibly as
”
defective”. Alternatively, just mark the module as defective, it can be opened and switched off later in the
workshop;
•
prepare a new module in the same way as described in paragraph
above. Switch on battery, perform
diagnostics and setting as described in pargraph
”
Functional check of the module”. Especially check
and set counter initial value as descrobed in paragraph
??
”
Commands for setting of input counters” and
broadcasting period as described in paragraph
”
Commands for setting of timers”. Alternatively, alls
these settings (excepting
”
downlink” mode) can be performed via optical converter after mounting to gas-
meter;
•
place front lid to the module base and affix it by screw. Mount the assembled module onto the gas-meter and
seal by antifraud seal;
•
write down the new module ID, gas-meter counter status and seal number. Fill in the prescribed service
documentation. If possible, arrange making of all appropriate changes in the database of the remote reading
system immediately.
4.8
Module dismantle
When dismantling from gas-meter, remove sealing connection and detach the module from gas-meter. Remove front
lid from the base and switch the battery off (alternatively, this could be done later in the workshop). Mark the
module as
”
dismantled” and fill in the relevant documentation, prescribed for this situation by the internal rules.
If possible, arrange deactivation of the module in the database of remote reading system immediately. Take off an
external antenna (if used).
4.9
Functional check of the module
After putting the module into operation (or after each repair and replacing of the module) it is recommended to
check its basic functionality:
•
before installation check setting of module and examine availability of Sigfox network radio-signal by sending
of several messages with using of ”T” command as described in paragraph
”
Commands for module
activation and diagnostics” and receiving them in the central system.
Alternatively, examination of the
network signal can be performed by using of Sigfox signal tester;
•
after installation to the gas-meter check correctness of reading system by repetitive inspection of counter
current value (”Value1”) by using of optical converter. If there is a real gas consumption in progress, counter
value should change in correspondence with changing of mechanical counter value. Values of physical quantities
(temperature, voltage..) should correspond with reality;
•
check setting of broadcasting period;
•
perform complex (end-to-end) check of implementation of the module into the remote reading system by
inspection of data rendered by module in reading system database. If the module broadcasting period is quite
long, set shorter period for testing.
After testing don’t forget to set correct value of broadcasting
period (in accordance with service contract!
