If the device is defective, it is pos-
sible that the watchdog responds
cyclically, what results also in a
cyclically flashing of the
RDY-LED.

When switched on, the PKV performs a self-test. If this is performed without er-
ror, the yellow RDY LED is switched on. Otherwise, the LED starts to flash, and
further running of the program is aborted.
If no firmware has been loaded in the PKV, the bootstraploader displays this by
regular flashing of the RDY LED at one second intervals. The flash frequency is
increased to approx. 5 Hz while the firmware is being loaded.
Stays the LED off the may be a defect.
If a parameterization error is detected by a protocol task, the task is displayed by
the RUN LED as shown in the illustration below.
If no error occurs and communication has started, the RUN LED is switched on.
Is this LED blinking cyclic, no parameterization error has been detected, but the
communication on the bus has not been established.
If communication is blocked, e.g. by the 'System start' parameter, the RUN LED
remains off.
The red LED ERR1 and ERR2 displays data transfer errors at the communicati-
ons interface to the connected devide.
