F.1129 Fault on inverter
F.1129
System characteristics
Inverter protects connected components by controlling
the current feed (secure operation).
Cause
Fault on inverter from another manufacturer
Measures
1. See inverter documentation.
2. Inform Viessmann Technical Service.
F.1130 No connection to the datalogger
F.1130
System characteristics
■
Limited functionality of Viessmann Energy Manage-
ment (HEMS)
■
Inverter protects connected components by control-
ling the current feed (secure operation).
Cause
No connection between Viessmann Energy Manage-
ment (HEMS) and datalogger (from other manufac-
turer, e.g. Solar-Log)
Measures
1. Check connection status via web interface of data-
logger.
2. Check connecting cable and plug-in connection
between datalogger and inverter (LAN, RS484,
RS232, etc.):
■
Check wires and plugs for correct seating.
■
Check connections for contact corrosion.
■
Check cables for mechanical damage, e.g. crush-
ing, kinking, chafing or breakage.
3. Perform measures as per documentation for inver-
ter.
4. Replace inverter.
5. Inform Viessmann Technical Service.
F.1131 Network fault (LAN)
F.1131
System characteristics
■
Limited functionality of Viessmann Energy Manage-
ment (HEMS)
■
Inverter protects connected components by control-
ling the current feed (secure operation).
Cause
Network fault (LAN)
No connection between Viessmann Energy Manage-
ment (HEMS) and external photovoltaic gateway, e.g.
Solar-Log Base Vi gateway
Measures
1. Check messages of Viessmann Energy Manage-
ment (HEMS) via ViGuide.
2. Check LAN cable and plug-in connection between
Viessmann Energy Management (HEMS) and exter-
nal photovoltaic gateway:
■
Check wires and plugs for correct seating.
■
Check connections for contact corrosion.
■
Check cables for mechanical damage, e.g. crush-
ing, kinking, chafing or breakage.
3. Check network configuration for Viessmann Energy
Management (HEMS) via ViGuide.
4. Check network configuration via web interface of
external photovoltaic gateway.
5. Inform Viessmann Technical Service.
