Bucyrus International, Inc. 8200 Walking Dragline
TYPICAL START-UP To start up the machine from a complete shutdown, use the following procedure. DO NOT start this machine unless you are completely familiar with the various controls. Perform the Pre-Start Inspection given on the previous page. 1.
All the circuit breakers for the applicable controls and equipment must be closed and power on before proceeding with start-up. These are located primarily on the outside of the Power Control Room (PCR) and in the Operator’s Cab/Anteroom. CAUTION:
2.
DO NOT use circuit breakers as ON/OFF switches. Make sure that all the circuit breakers are ON before starting the machine.
Go to the rear of the PCR and to the Starting and Metering Cabinet. Observe the various meters and the start-up controls and that the PHASE CHECK light is on. IMPORTANT NOTE: During each component start-up always be ready to immediately stop it if there are any unusual sounds, smells, or visual effects. Always let the system being started come up to its normal operating speed before starting the next system. Any time a problem arises, check the OIT display in the Operators cab for assistance.
4.
Start the motor blowers by pressing and releasing the START pushbutton. These blowers are used in cooling the DC motors. Check that the green indicator is lit and for the sound of the blowers.
5.
Start the No. 1 M.G. Set by fully pressing and releasing the START pushbutton. Be sure that both green indicators are lit and that all meters are stabilized.
6.
Start the No. 2 M.G. Set in a similar manner to the No. 1 M.G. Set. IMPORTANT NOTE: If the vacuum breaker for the synchronous motor on the M-G set does not stay closed when the start button is released, repeated attempts to start the set should not be made. On a motor of this type, only attempt two successive starts if the motor is at ambient temperature. More than two attempts to start without success can damage the motor windings. Before attempting another start, the vacuum breaker starting circuitry or mechanism should be inspected by qualified personnel and its proper operation verified.
