Abstract

943,289. Control of motors. BARMER MASHINENFABRIK A.G. April 11, 1961, No. 13079/61. Heading H2J. A machine for treating thermoplastic material has four heating zones and a part such as a conveyer is driven by an electric motor, starting of the motor being prevented until each of the zones has reached a pre-set temperature. An auxiliary contactor 7 is operated by actuation of manual switches 3-6, whereupon contactors 8 switch on the heating current for the zones and open contacts 9-12. A contact 13 is closed by the contactor 7 to prepare the circuit for contactors 14-17. After the desired temperature has been reached in each zone, the associated contactor 8 falls out. A circuit is then completed through contacts 13 and 9 to contactor 14 which closes contacts 22. Contacts 23-25 are similarly closed when the associated zone reaches a pre-set temperature, so that a signal lamp 26 is energized through circuit-breaker 27. Closure of starting switch 28 then completes the circuit for a selfholding contactor 29 for the drive motor. In another embodiment, the contacts 22-25 are in series with the coil of a common contactor having a single contact controlling the contactor 29.
