Abstract
881,800. Control of motors. PRVNI BRNENSKA STROJIRNA, ZAVODY KLEMENTA GOTTWALDA NARODNI PODNIK: Jan. 6, 1960, No. 496/60. Class 38 (3). The outward motion of a steam-boiler blower is started by closing push-button 22 to energize coil 24 of reversing contactor 18. This causes the closure of contacts 33 whereby motor 32 is set in motion to displace the blower from its initial position. The closure of contacts 26 completes a holding circuit for the coil 24. If the blowing-pipe is obstructed, an over-current relay 1 closes contacts 2 to energize coil 3 of a time delay relay. After a period, contacts 4 close to energize coil 5 of an auxiliary relay and to light a signal lamp 16, the closure of contact 8 actuating a signal horn 15. Contacts 9 complete a holding circuit for coil 5, contacts 6 opening to interrupt the circuit of coil 24. Contacts 27 then close the circuit of coil 23 and the motor is reversed to retract the blower until a limit switch 19 is operated.
