•
connect the antenna and signal cables to the module;
•
make sure that the power supply is turned off and connect the power cable to the module. Verify that the
polarity of power supply corresponds with the marking on the module terminals;
•
check whether everything is properly connected and fasted and turn on the power supply. Green LED
”
Power”
will shine on the module and the operation system will start up;
•
perform the basic diagnostic of the module in compliance with the procedure mentioned in the paragraph
”
Functional check of the module” and possibly (if the module was not pre-configured during the prepara-
tory stage of installation) its configuration with using of the configuration cable according to the procedure
described in the paragraph
”
Configuration of the module individual parameters”;
•
record information about the module installation (serial number, position, picture of installation...) to the
operational documentation under internal rules.
When locating installation site, selecting antenna type and antenna position it is necessary to take into account con-
ditions for radio signal propagation in the area of installation. The conditions is possible either estimate empirically
on the base of previous experience, or accomplish a measurement of the signal strength by the signal analyzer.
5.7
Module replacement
When there is necessary to replace the module due to the module failure follow this procedure:
•
switch off the power supply and disconnect the power cable wires from the module;
•
disconnect the signal cable and the antenna cable;
•
release the module from DIN-rail by pulling down of the black plastic lock on the bottom side of the module
down (outward of the module) and remove the module from the rail;
•
attach the new module at the place of the original module and proceed further according to the procedure
mentioned in the paragraph
. Especially pay attention to the correct connection of the power cable;
•
after switching power on perform the diagnostics and set-up parameters;
•
label the original module as
”
defective” and fill in the appropriate documentation prescribed by internal rules
for this case.
5.8
The module dismantling
When dismantling module turn the power supply off and disconnect the power supply cables from the module.
Disconnect the signal cable and the antenna cable from the module. Release the module from DIN-rail by pulling
down of the black plastic lock on the bottom side of the module (outward of the module). If there is no further
use for the antenna, remove the antenna cable and the antenna. If there is no further use for the power supply,
remove the power supply and the power cable. If the power supply is used for other purposes, secure power cables
against short circuit (by insulation of live ends of wires or by removal of useless power branches) and connect
the power supply again. After dismantling label the module properly as
”
dismounted” and fill in the appropriate
documentation prescribed by internal rules for this case.
5.9
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 Internet connection via GSM-modem and testing of the receiver functionality in the
”
Radar” mode.
A quick check of the functionality of the Internet connection
can be performed immediately after switching
on the module using the data on the LCD display. Check the connection to the GSM network in the
”
GSM Info”
display, check the functionality of the 169 MHz receiver in the
”
CC1120” display, and go through the group of
terminals within the reception area in the
”
History” display.
The
”
History” table is filled in gradually as the individual terminal devices
”
ring” one after the other. When
installing a local Wireless M-Bus collecting network, it is advantageous to put the gateway into operation first, and
just then the individual terminal devices. This way it is possible to check continuously the success of the installation
of individual terminals from the laptop with the
”
Modules online” (
”
Radar”) table opened in the WEB browser
(see the description in paragraph
”
Setting the module parameters via the Internet data network”. This way the
quality of the connection between the transmitting devices and the communication gateway can be also checked.
A detailed check of the settings of all parameters can be performed using a laptop and a program for communication
over the serial line (for example
”
PuTTY”) as described in paragraph
”
Configuration of the WB169-RFG module
by using the configuration cable ”.
