Fault Acknowledgement; Fault Memory; Error Codes; Further Steps For Troubleshooting - Wilo Control SC-L Notice De Montage Et De Mise En Service

TROUBLESHOOTING AND POSSIBLE SOLUTIONS
• When a fault occurs, the red collective fault signal
LED lights up and the collective fault signal is
activated. The error code is displayed for 30 s on
the display. Thereafter the error code can be read
from the fault memory.
• Faults that only lead to switching operations once
a set time has elapsed are indicated by a fl ashing
fault alarm LED. The error code is displayed for
30 s on the display. Thereafter the error code can
be read from the fault memory.
• Self-acknowledging faults such as dry run, high
water, etc. are displayed by a fl ashing fault signal
on the main screen and can be read in the fault
memory.
• A fault on one of the connected pumps is indicat-
ed on the main screen by a fl ashing status symbol
for the corresponding pump.

10.2. Fault acknowledgement

Acknowledgement of the individual errors is via
the menu.
Select menu 6.0.0.0.
Select menu 6.1.0.0 and press the operat-
ing knob --> the error symbol fl ashes.
Turn the operating knob once to the right.
The error symbol appears marked "reset"
and fl ashes.
Press the operating knob. All faults elimi-
nated are acknowledged and the fault LED
goes out.
If the fault LED continues to be lit or fl ashes, not
all errors have been eliminated. Check the indi-
vidual errors in the fault memory, eliminate these
and reacknowledge these faults.

10.3. Fault memory

The switchgear stores the last 16 errors in the
fault memory. The log uses the FiFo principle
(First in/First out).
1. Select menu 6.0.0.0.
2. Select menu 6.1.0.0.
3. Select menu 6.1.0.1.
4. The last fault appears.
5. Turn the operating knob to the right. You
will then scroll through the fault memory
(6.1.0.1 to 6.1.0.16).
