Goodrive270 series VFD for fan and pump Maintenance
-287-
Check whether conductors are
deformed or color change for
overheat.
Check whether the wire sheaths
are cracked or their color
changes.
Check whether there is
damage.
Check whether there is
electrolyte leakage,
discoloration, cracks, and
chassis expansion.
Check whether the safety
valves are released.
Determine the
service life based
on the
maintenance
information, or
measure them
through
electrostatic
capacity.
Check whether the electrostatic
capacity is measured as
required.
Use instruments
to measure the
capacity.
Electrostatic
capacity ≥ initial
value x 0.85
Check whether there is
displacement caused due to
overheat.
Olfactory and
visual inspection
Check whether the resistors are
disconnected.
Visual inspection,
or remove one
end of the
connection cable
and use a
multimeter for
measurement.
Resistance range:
±10% (of the
standard
resistance)
Check whether there is unusual
vibration sounds or smells.
