2.5 Status Displays
There are four LEDs available of the PKV 30-COS for status displays:

Condition
Meaning
With a device defect, the conti-
nuous accessing of the Watchdog
Supervision can also lead to a cy-
clic blinking of the RDY-LED.

CAN message sent
- No error shows communication
operation is on
ERR 2
red
on
The device is not currently in an
operational condition but did once
reach operational readiness. This
means that a running
communication to the Master has
been interrupted.
After switching on, the PKV carries out a self-test. If this has been run through
successfully, then the yellow RDY-LED is switched on. Otherwise the LED be-
gins to blink irregularly and the further processing of the program is aborted.
If no field bus Firmware is loaded on the PKV, then the Bootstrap loader shows
this by a cyclical blinking of the RDY-LED in a 1-second rhythm.. During the
loading of the Firmware, the blink rhythm increases to approximately 5 Hz.
If the LED remains off, then there is a defect of the PKV.
If a Protocol Task recognizes parametrizing error, then the Task is displayed by
the RUN-LED in accordance with the following figure. If there is no error and
communication could be started, then the RUN-LED is switched on. If the com-
munication operation is blocked, then the RUN-LED remains off.
