This is to allow the motor to reach the end limit of the crane. After the motor reaches the end of travel (indicated by the delay time durations), the motor will stop and red pilot light H2 will turn On. • The control supply for this circuit is 48Vac.

- QUESTION 18 The instantaneous contacts of a timer are drawn in the same manner as standard relay contacts. True Falsearrow_forwardA single-phase electric motor is connected to a 240-volt, 30-ampere circuit. The motor nameplate indicates that the full-load current draw of the motor is 21 amperes. The motor is connected to an inertia load (a large flywheel) that requires several seconds for the motor to accelerate to full speed. Because of the long starting time, the motor causes the circuit breaker to trip before the load has reached full speed. Your job is to connect a resistor in series with the motor during the starting period that will limit the starting current to 90% of the circuit-breaker rating. An ammeter indicates that the motor has a current draw of 64 amperes when power is first applied to the motor. Determine the ohmic value and wattage rating of the resistor that should be connected in series with the motor during the starting period.arrow_forwardLockout is required: During servicing and maintenance where unexpected ener- gization or start-up of equipment could harm employees.
