9 FAULT CODES
9.1 General
Fault codes are used to indicate that a fault has occurred in the equipment. They are shown
in the display in the form of a symbol as follows:
Fault codes are updated every three seconds. The upper numeral in the
symbol is the number of the particular fault code. The lower figure indicates
where the fault is.
The above symbol shows that the control panel (0) has lost contact with the power unit.
If several faults have been detected, only the code for the last fault to occur will be displayed.
Press any of the function keys in order to clear the symbol from the display.
Symbols may be steady or flashing, depending on the type of fault.
Flashing symbols are highlighted with “o” in the list of fault codes.
