DIAGNOSTICS AND TROUBLESHOOTING
DANGER!
Seul un personnel formé, ayant les qualifications adéquates et familiarisé avec le the MVW01 et l’équipement associé peut
planifier et mettre en oeuvre l’installation, le démarrage, l’utilisation et la maintenance de cet équipement. Ce personnel
doit suivre toutes les instructions de sécurité décrites dans ce mode d’emploi et/ou définies par la règlementation locale.
Le non-respect de ces instructions de sécurité peut entraîner la mort, de graves blessures et/ou des dommages aux
équipements.
Procedures:
1. Operation of the fans and exhausting fans:
Verify the proper operation of the exhausting fans at the top of the rectifier cabinet and the inverter cabinet. The fans must be running in the
same direction and their exhausting action must be perceptible. Verify the proper operation of the fan at the control cabinet: it must be running
and blowing air into the cabinet.
2. Cleaning of the air inlet filters:
Remove the protection grids from the air inlets at the doors of all the cabinets by unbolting them. Remove the filters and clean, wash or replace
them. The amount of accumulated dirt on the filters helps defining the correct interval between preventing maintenances. Reinstall the filters
and bolt the protection grids again.
3. Open the control cabinet and visually inspect the components inside it, verifying them to identify faults or the need of preventive maintenance
with complete stop/de-energization for cleaning or replacement:
Components
Anomalies
Electronic boards
Excessive accumulation dust, oil, moisture, etc. Discolored or darker points due
to excessive heat
Capacitors on electronic
boards
Discoloration, smell, electrolyte leakage, case deformation
Resistors in general
Discoloration or smell
Control rack (A8), elec-
tronics power supply
PS24 (A11).
Excessive heating of the aluminum base (more than 40 °C, 104 °F, above the
ambient temperature).
