Operating instructions
3.3.2 Critical, faulty operation
A comprehensive safety concept limits the number of critical conditions that can occur
to a single situation:
Input voltage exceeds the permitted value
This is indicated by the following blink-code on the yellow LED:
The yellow fault LED illuminates for 5 seconds when the fault occurs, and then begins
displaying the blink code of: 3 seconds off and then 4 times briefly on. This code is
displayed three times in succession. If the fault is still present, the fault display starts
again from the beginning
.
3.3.3 Non-critical, faulty operation
All other fault codes indicate some form of faulty operation, which are not usually
dangerous to people or equipment, but which should nevertheless be investigated
and corrected.
Despite all precautions, it is possible that other faults may occur that cannot be dis-
played (e.g. failure of the status display). In order to recognize such faults, the oper-
ator of the system should use the explanations in chapter 3.3.4 "Description of the
operational status” (page 19) to check the plausibility of the displayed status.
Further detailed diagnoses are possible using the communication options detailed in
chapter 7 "Expansions” (page 39).
The presence of excessive input voltage can lead to irreparable
damage! Immediately disconnect the DC input of the Windy Boy.
When the Windy Boy receives an excessive DC input voltage, it automatically
disconnects from the mains network and no longer feeds power into the grid.
When the Windy Boy is in operation, you must always first disconnect the AC
voltage (mains supply) and only then should you disconnect the DC voltage
from the Windy Boy!
