3.6 Fuse Check Failure
Display indicates ‘SWITCH ON?’
Possible Reasons for Failure
uAppliance mains switch not set to the ON position.
Rectify and restart the test,
uAppliance not correctly connected to the HPAT400.
Rectify and restart the test,
uRuptured fuse.
Remove any fuse(s) and check fuse continuity by
an alternative means. Ensure that the appliance is
disconnected from any mains power whilst fuses are
being examined.
Re-insert any fuses.
Reconnect appliance to HPAT400, ensure operating
switch of appliance is ON and restart whichever Class
of test had been desired.
uAppliance internal circuitry.
If the fuse(s) are proved to be undamaged, the
‘SWITCH ON?’ remark on display may be due to a
switching device inside the appliance that only operates
when the appliance is energized at mains voltage.
A ‘fail’ in such circumstances does not necessarily
mean a fuse is ruptured or the appliance is faulty.
When the ‘SWITCH ON?’ message is displayed, the
HPAT automatic testing can be allowed to continue by
selecting ‘SKIP’.
Exit Test
If it is decided that the appliance is faulty, when the
‘SWITCH ON?’ message is displayed, the test should
be terminated by selecting ‘EXIT’ and unplugging the
appliance from the HPAT.
