Problems solved by technology

[0002] In the field of industrial manufacturing, a large number of repetitive operations are performed every day when starting up equipment. When large-scale equipment covers a large area or is far away, and when the equipment is overhauled and started, due to the inconsistent cooperation of operators or maintenance personnel, there are still people who are still there when starting up. Overhaul, easy to cause personal accidents

Abstract

The invention discloses a startup control circuit with an acousto-optic early warning function, wherein the secondary line power supply port A and the power supply port B are externally connected witha 220V alternating current power supply; The method is characterized by comprising the following steps; the control circuit further comprises bipolar circuit breakers QF1 and QF2, a stop button SB1,a start button SB2, an early warning intermediate relay KA1, an early warning time relay KT1, an audible and visual alarm HAB, an operation contactor KM, an early warning indicator lamp HD1, an operation indicator lamp HD2 and a thermal relay FR. The circuit is simple, easy and convenient to operate and reliable in operation, and safe production is guaranteed.

Description

technical field [0001] The invention relates to a control circuit, in particular to a start-up control circuit for sound and light warning. Background technique [0002] In the field of industrial manufacturing, a large number of repeated operations are performed every day when starting and starting equipment. When large-scale equipment covers a large area or is far away, and when the equipment is overhauled and started, due to inconsistent cooperation between operators and maintenance personnel, there are still people who are still there when starting up. Overhaul may easily cause personal accidents. Contents of the invention [0003] The object of the present invention is to provide a start-up control circuit for sound and light warning. When starting up, first the sound and light alarm works to remind operators and maintenance workers to pay attention. After a time delay, the motor starts to run, thereby preventing safety accidents. The circuit is simple, easy to oper...
