1KHW001489-EN
Explanation and corrective actions
(the latter in italics)
Communication with the P4LT/P4LU board is disturbed.
Make sure that the board is firmly plugged in. Unplug the
board and check if all pins of the connector to the
backplane are present and not bent. If the error message
appears repeatedly, replace the O4LE board.
Explanation and corrective actions
(the latter in italics)
A test configuration for the board is active which will be
lost when the asscociated test configuration timer runs out.
Store the configuration to EPROM, stopping the test
configuration timer,
overwriting the test configuration timer.
The 2-wire subscriber or service phone port is overloaded.
Unplug the wires connected to the ports. Check the wires
for short circuits and check the subscriber and service
telephone sets. If the error persists, replace the board.
Explanation and corrective actions
(the latter in italics)
The NSK600 DSP / MOD600 DSP on P4LT stopped
working for more than 1 s longer than the configured
pickup time for hardware alarms, followed by an automatic
reset of the system. The reason can be faulty P4LT
hardware or excessive EMI, possibly in combination with
poor substation grounding and/or not properly grounded
cable shields.
Connect the shields of cables to ETL600 to ground as
described in 6. Improve the grounding of ETL600, specially
the connections between the buried earth grid and
substation ground, substation ground and cabinet, cabinet
and (swing) frame, (swing) frame and equipment rack.
If external EMI effects can be excluded and the error
message appears repeatedly, replace P4LT.
