Note:
Fault codes 71, 72, 79, 73, 64, 62 and 74 are reset automatically as soon as their cause has
been removed. Fault codes 63 and 81 must be reset (acknowledged) explicitly by restarting the
SM. Alternatively, FC63 can be reset via the BM-Solar (by holding down the rotary selector for at
least 5 seconds).

Troubleshooting

If faults occur at the SM solar module, the corresponding fault
code and a warning symbol will flash on the display.
Example:
The standard display will return when the fault has been removed.
The following fault messages can occur at the solar module:
Cause
throughput
Faulty gravity brake
Pulse generator or cable
faulty
Faulty sensor or lead
Faulty sensor or lead
No BUS connection; no
DCF reception
Parameter values
outside valid range
flashing
Remedy
Check solar circuit pump
Check gravity brake
Check pulse generator
and cable; replace if
required
Check sensor and lead;
replace if required
Check sensor and lead;
replace if required
Check sensor and lead;
replace if required
Check eBUS
connection/DCF
reception
Check sensor and lead;
replace if required
Reset to standard
values by briefly
interrupting the power
supply, and check
values
