Explanation and corrective actions
(the latter in italics)
The transmission of data via embedded operation (EOC)
channel 1 is disturbed.
Make sure that identical firmware versions are in use in
both local and remote equipments. Check if the quality of
the receive signal in terms of SNR and receive level is
adequate. Reset ETL600. If the error persists, replace
P4LT.
At least one of the tests switches under Equipment /
Tuning and Testing / Test PLC-link or Equipment /
Commissioning and maintenance / Test PLC-link is
active.
The ETL600 is not in normal operation mode. Reasons for
that might be
- any test switch is active,
- any Tuning and Testing procedure is ongoing,
- frequency response measurement is ongoing,
- the dummy load is plugged
Different firmware versions on local and remote equipment
are in use.
Use identical firmware in both equipments.
A test configuration is active which will be lost when the
associated test configuration timer runs out.
Store the configuration to EPROM, stopping the test
configuration timer,
overwriting the test configuration.
A dummy load has been inserted for test purposes,
replacing the RF hybrid and interrupting the link.
When the tests are terminated, remove the dummy load
and reinsert the RF hybrid.
A warning is present on at least one of the O4LE boards.
Check O4LE status for detailed information.
P4LT receives a warning from the 80 W power amplifier.
One of the two 40 W amplifiers P1LA used to generate the
80 W output may be faulty.
Replace the faulty modules
The event recorder has performed a block rotation. This
happens automatically if the nonvolatile memory assigned
to the event recorder is full. Some of the memory is freed
by discarding the oldest recorded events.
