Abstract
PURPOSE: To prevent heaters from over current at starting of operation by a method wherein a plurality of the heaters applied with thermistors having negative characteristics are connected in series at the starting of the operation while they are switched into a parallel connection after temperatures thereof are arrived at constant temperatures substantially.
CONSTITUTION: In a system consisting of heaters (PTC heaters) 3, 4 applied with thermistors having negative characteristics and a switch 6 for the heaters, a relay 5 equipped with contacts aWf is annexed thereto. This relay 5 is set so that the con- tacts a-b, d-e are closed during a period wherein temperatures of the heaters 3, 4 are rising to temperatures near using points thereof, thereafter, the contacts are switched into connections of a-c, d-e in any way, by either switching in cooperated with a timer after 4W5min after beginning of operation or switching by sensing the temperatures of the heaters 3, 4. According to this method, the heaters 3, 4 are connected in series during the temperatures thereof are low upon beginning of the operation, thereafter, are switched into a parallel connection after the temperatures thereof are risen enough.
