Troubleshooting
The following points should be checked when the system does not operate
regarding the GSM/GPRS modem connection or the interfaces:
1.
Is the mains voltage present (meter liquid crystal display legible, green
LED on CU-adapter is on)?
2.
Is the GSM signal level sufficient (at least RX LED is on)?
3.
Is the maximum permissible ambient temperature not exceeded?
4.
Are there any changes or damage visible in the installation?
5.
Check the status of the LEDs according to section 5 "Operation".
If none of the points listed leads to a resolution of the fault, the communica-
tion unit should be removed and sent to the responsible service and repair
centre.
6.2
Repairing the communication unit
Communication units must only be repaired by an authorised service and
repair centre (or by the manufacturer).
Meter operation only with communication unit or "dummy"
For safety reasons the meter must not be operated without communication
unit or a "dummy" communication unit.
Adopt the following procedure if a repair is necessary to the communication
unit:
1.
If installed, remove the communication unit and fit a replacement com-
munication unit. If no spare communication unit is available, a "dummy"
unit must be used.
2.
Describe the error found as exactly as possible and state the name
and telephone number of the person responsible in case of inquiries.
3.
Pack the communication unit to ensure it can suffer no further damage
during transport. Preferably use the original packing if available. Do not
enclose any loose components.
4.
Send the communication unit to the responsible service and repair
centre.
