LED "Error" and error displays
LED Error indicates a system error. At the same time an error message will appear in the display
according to the following example:
F A T A L - E R R O R !
C h 1 : S F : 0 D / H W : 0 9
C h 2 : S F : 2 D / H W : 0 0

Pressing the
key facilitates switching between L1/L2 and the measured-value display.
Pressing key
Flags
makes it possible to display selected error flags.
Actuating keys
or
facilitates swapping between the display of the SF flags and HW flags
(hardware flags).
In the HW-flag display mode additional displaying of the flag values is possible indicating voltage supply
errors/sensor errors (V-Exc-Flags 1/2).
