Claims

[Scope of utility model registration request]

Manual reset type magnetic reversal indicator, latch type polarized relay,
A power supply circuit comprising a pulse generation DC transformer and at least a permanent magnet for returning the manual return type magnetic reversal indicator, and a primary winding end of the pulse generation DC transformer is closed upon detection of a failure. 2 of the pulse generating DC transformer.
A drive coil of the manual return type magnetic reversal display and a drive coil of the latch type polarized relay are connected to the next winding end, and the permanent magnet is manually operated at least at the manual return type magnetic reversal display. It is movable so as to approach the display, and is capable of restoring at least the display state of the manual return type magnetic reversal display, so that the manual return type magnetic reversal display can visually detect a failure. A fault display device characterized in that the contact of the latching type polarized relay is used as a warning contact so that an alarm is issued while the fault continues.
