Troubleshooting Failures And Faults - Advanced Energy AE 3TL 600 Series Installation And Operation Manual

TROUBLESHOOTING FAILURES AND
FAULTS
WARNING:
Maintenance personnel must receive proper training before installing,
troubleshooting, or maintaining high-energy electrical equipment. Potentially
lethal voltages could cause death, serious personal injury, or damage to the
equipment. Ensure that all appropriate safety precautions are taken.
AVERTISSEMENT:
Le personnel d'entretien doit recevoir une formation appropriée avant
d'installer, de dépanner ou d'entretenir un équipement électrique à haute
énergie. Des tensions potentiellement mortelles pourraient provoquer la
mort, des blessures graves ou des dommages à l'équipement. S'assurer que
toutes les consignes de sécurité appropriées ont été respectées.
DANGER:
This unit contains energy storage devices that take up to 5 minutes to
discharge. Verify the high energy capacitors are completely discharged
before working on this unit.
DANGER:
Cette unité contient des dispositifs de stockage d'énergie qui prennent
jusqu'à 5 minutes pour se décharger. Vérifier que les condensateurs à haute
énergie sont complètement déchargés avant de travailler sur l'unité.
The inverter display screen is the primary indicator of a possible problem with the
inverter. The inverter can detect and display inverter failures and faults.
• Temporary failure: Inverter disconnects temporarily from the AC main, the red
ALARM LED flashes on the control panel, and the temporary failure is
automatically acknowledged by the inverter and a startup attempt is made if the
message is no longer pending. The failure is saved in memory.
• Fault: During operation, permanently programmed and parameter limits are
monitored continuously. To protect the inverter power section from damage, the
inverter is disconnected from the voltage if a limit value is exceeded or a fault
occurs. The red ALARM LED is continuously lit. The last 100 faults are saved
in memory.
For each category, the following occurs:
• Fault text is displayed on the screen
• Alarm LED is flashing or solid
