Assign each device a clear and unique name to each meter, for example,
"Apartment 1", "Basement", "Hot water" to simplify the evaluation of reports on
consumption data or device information on the web server.
See Section Settings / Wireless devices / Device settings. Page 100.
8.5 Web server troubleshooting
The device does not switch on. The green LED is off.
 Using a multimeter, check whether the required operating voltage AC/DC 24 V
+/- 10 % is available between terminals (15) and (16).
The display is switched off.
 The display switches off automatically after 10 minutes. Press any button to
switch on the display.
The web server does not recognize any devices.
 Check to ensure the wiring is correct between the web server and connected M-
bus devices.
 Check to ensure the wiring is correct between the web server and the level
converters.
 Check M-bus wiring for short circuits.
The web server does not recognize all M-bus devices.
 Check to ensure the wiring is correct between the web server and unrecognized
devices.
 Using a multimeter, check whether the bus voltage on the unrecognized devices
is between DC 24 V and 42 V.
 Ensure that the communication settings on the web server are compatible with
the M-bus devices (transmission rate, addressing)
 Check to ensure that the number of connected M-bus devices does not exceed
the maximum permitted amount.
The web server does not recognize all radio devices.
 Ensure that the unrecognized devices are not located too far from the web
server and that the radio signal is not too weakened by cement or metal walls
 Ensure that the unrecognized devices are loaded to the web server list and that
contact to the wireless M-bus devices, recognized by the web server, is not
interrupted.
 Please note that some wireless M-bus devices only transmit their data at
intervals of multiple hours
 Use the web interface or the ACT531 software to ensure that the mesh network
is operational.
No connection with the web server.
 Check the PC network address. The web server uses an IP address
192.168.1.110 as the default. As a result, the PC must have an IP address of
192.168.1.xxx (with xxx not equal to 110).
 Ensure that a firewall is not blocking TCP/IP Port 80 or 443.
 Please contact your local IT administrator for excluding network problems
