4.8 Indicator LED of compact version
The Electronic-Key adapter operating states are indicated using a three-color LED on the front.
The illumination of the LED in any color indicates the presence of the operating voltage.

After the application of the power supply, the LED is constantly illuminated red
during power-up. The completion of the process is indicated by a change in this
state after approx. 10 seconds. If the LED then flashes red quickly, it is an indication
of a network fault.

4.9 Indicator LEDs of modular version
The operating states of the read/write stations are indicated via LEDs in three colors.
On the FHM Electronic-Key adapter, the state of the identification system is signaled by a single three-color
LED. On the interface adapter, the same state is signaled by three individual LEDs (read head) in different
colors. The illumination of the LED in any color indicates the presence of the operating voltage.
The state of the data interface is additionally signaled via two individual LEDs in different colors on the interface
adapter (Ethernet TCP/IP).
