項記載のソリツドステートリレー故障判断回路。[Scope of Utility Model Registration Claim] (1) Turns on and off the power supplied to the heater from the power supply in response to a heater on/off command signal from the control unit.
A solid state relay that controls off; detects the simultaneous output of a heater off command signal from the control unit and an on signal from the solid state relay, determines a failure of the solid state relay, and outputs a failure signal. A solid state relay failure determination circuit comprising: a failure determination circuit; (2) The failure determination circuit includes a first relay that keeps its contacts closed while the heater OFF command signal is output from the control unit and opens the contacts upon receiving the ON command signal; and a solid state relay. a second relay that closes the contacts upon receiving an on signal and maintains the contacts in an open state upon receiving an off signal;
Utility model registration claim No. (1) characterized in that the relay and the second relay are connected in series.
The solid-state relay failure judgment circuit described in .
