3.3 LEDs
All LEDs (except L1, L2, L3 and the clock symbol) are two colored. The LEDs on the left side, next
to the alphanumerical display light up green during measuring and red after fault messages.
The LEDs below the push button <SELECT/RESET> are lit green during setting and inquiry proce-
dure of the setting values which are printed on the left side next to the LEDs. The LEDs will light up
red during parameterizing of the setting values next to their right side.
Remarks:
Due to the fact that there are a variety of protection functions, it is not possible to assign each indi-
vidual function to one separate LED. For this reason, some of the measured values or parameters
are indicated by simultaneous flashing of several LEDs.
Example: To indicate the function of parameter U<, the LEDs next to U and 1 and < are lit up.
You can find an overall list showing the assignment of functions and LEDs in Chapter 5.1 and at
the end of this description.
