Design and Functions
Each state has a meaning regarding whether an error occurred and how serious the error is.
The following table shows what states can be signalized by the five LEDs:
Table 1: Meaning of LED signals
LED Colour Status

Meaning
PWR A yellow ON Supply voltage channel A available
OFF Supply voltage channel A not available
PWR B yellow ON Supply voltage channel B available
OFF Supply voltage channel B not available. The sensor head is in the energy saving
mode because of low voltage supply or there is no power supply at all.
RUN green Flashing
5 Hz
Safe position data is transmitted via the interface

The sensor head is operating in single-channel mode. Non-safe position infor-
mation is transmitted via the interface.
Static
light on
The sensor has been blocked intentionally. Also see: LED
ERR
.
ERR red OFF No error
Flashing
1 Hz
At least one error has been detected, but it is not classified as a severe error.
Find more information on the problem in the Error Register (

12.2.3)
The exact cause is transmitted via the interface to the evaluation unit as long as
the sensor is in dual-channel operation (

9.5.4) In single-channel operation;
no detailed error diagnosis is possible.

The sensor had has blocked itself due to a severe error. The unit should be
replaced. The exact cause is communicated via a flashing code of the LED
