Soft start control cabinet

Soft start control cabinet

Description

The soft start control cabinet reduces the starting current of the motor, reduces the volume of the power distribution equipment, prevents investment in power projects, reduces starting stress, and increases the service life of the motor and related machinery and equipment. With a wide range of start-up methods and a wide range of current and operating voltage settings, it can be integrated into a wide range of load conditions. The control box is used for loads such as centrifugal fans, centrifugal pumps, transportation and refrigeration compressors. Soft start control cabinet main performance: 1, intelligent motor soft starter function, intelligent motor protector function, programmable relay output function, programmable timing output function, programmable status indication function. Other ancillary functions

The soft start control cabinet minimizes the amount of starting current of the motor, reduces the volume of the power distribution equipment, prevents investment in power projects, reduces starting stress, and increases the service life of the motor and related machinery and equipment. With a wide range of start-up methods and a wide range of current and operating voltage settings, it can be integrated into a wide range of load conditions. The control box is used for loads such as centrifugal fans, centrifugal pumps, transportation and refrigeration compressors.

Soft start control cabinet main performance:

1. Intelligent motor soft starter function, intelligent motor protector function, programmable relay output function, programmable timing output function, programmable status indication function.

Other ancillary functions

1, digital ammeter, voltmeter, power meter function. , fault information storage (power loss is not lost) function, start time memory, start count statistics function, running status memory, power failure and automatic recovery after call, 0~20mA real-time current (not subject to CPU intervention) output function, built-in RS232 and RS485 communication interface, start delay (0~999 seconds), start interval delay (0~999 seconds), programmable output delay (0~999 seconds).

In the control box (box) control circuit of this series of products, there are both automatic control system and manual operation. It also has over current, over voltage, under voltage, phase failure maintenance and safety accident alarm. Before using this product, be sure to press After the electrical schematic diagram is checked, the wiring is adjusted according to the specific specifications of the motor, and then started.

1. Fully automatic operation: Connect the switch power supply, the indicator light is on, turn the transfer switch to the “automatic” part, and check whether the motor operated by the control box (box) is in the command position of the liquid level meter dust pulse control instrument. When the liquid level meter exceeds the operating liquid level meter, the matching liquid level meter display light is bright, the relative limit switch control relay normally open contact is fully closed, the control circuit is fully automatic, the motor is started, and the operation is performed together. The display light is on. When the water level line exceeds the termination water level line, the matching indicator light is illuminated, and the matching limit switch of the liquid level meter measuring and controlling device controls the normally closed contact of the relay to be broken, and the control circuit leads again, and the motor stops working, and the operation indicator light Blow out.

2, manual operation: access to the switching power supply, the indicator light is on, turn the transfer switch to the "manual" part, press and hold the start button, the motor starts running, the operation display light is on, press and hold the "terminate" button, the motor stops running, Its operation indicator light blows out.

3. No matter which control method is selected, when the limit water level line is exceeded, it exceeds the water level line data signal contact point to access, and the control circuit loses power again, causing the motor to terminate operation, and the light control report data signal is transmitted. If there is a safety accident during the whole operation of the motor, the safety accident display light is on, and the electric bell is fully reported. At this time, press and hold the end button to drive the motor to stop working.
