Troubleshooting
1KHW001489-EN
Explanation and corrective actions
(the latter in italics)
The TPE 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 section 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.
A memory error has been detected in the memory of the
TPE DSP on P4LT. 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 section 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.
At least one configured G4AI board doesn't answer or is
not plugged at the correct position in the rack.
Verify if all boards are firmly plugged in at the correct
positions in the P7LC subrack according to HMI600 (View
/ Display configuration). Switch off the power to ETL600
and switch it on again after some seconds. If the error
persists, find the faulty G4AI board(s) by studying the TDM
bus communication alarms (section 9.6.4). Replace the
faulty G4AI board(s).
