Product Description


Dual Power Supply Switching Control
Products Name:LSK electrical control cabinet structure

Control cabinet structure is divided into the main loop, control loop part, add-on parts

The main loop:

Refers to the power input through the circuit breaker, contactor, thermal relay contactor main circuit to the output terminal (connected to a motor) loop.

The control loop: From the signals received by a complete break or control circuit, protection circuit and display circuit fault.

External accessories: Liquid level gauge, pressure switch, float switch, electric contact pressure gauge, temperature controller, to achieve signal element automatic work.

Installation note:

1. The wiring before inspect the internal components for damage, loss, loose.

2. Check accuracy according to the control cabinet with the instruction manual wiring, correct connection of power line, ground wire, signal wire, thread must be pressed firmly.

3. Debugging before is not connected with the pump motor is no-load test, if the contactor motion and panel instructions are correct, then the motor wire.

4. With the current meter or clamp meter verification working current, the current of each line should be equal.
fault phenomenon failure cause elimination methods
  1.No power supply or one or two phase power supply is needed
Check all phases of power supply and restore power supply

 
  2.Poor contact of ac contactor and burning of coil
Repair or replace contactors

 
can not start 3.
The power switch is not closed, malfunction or damaged

 
Close the switch and replace it if the power indicator does not turn on
  4.
Thermal relay trip or damage

 
Check whether the motor is blocked, find out the reason and eliminate it.Manual reset is replaced if it cannot be started
  Water level is too low
Put water in the sink

 
  The motor burned
Repair or replace the motor

 
  1.Line is loose
Check wiring and tighten connectors

 
  2.Frequency converter malfunction Check the fault content, check the cause according to the frequency converter manual, and restart after reset.Or disconnect the inverter power supply for a few seconds, the inverter fault reset before starting.
The manual is normal 3The frequency converter is damaged Repair or replace
Automatic transmission failure 4.Pressure switch damage Repair or replace
  5The pressure transmitter is damaged Repair or replace
  6.Switch failure Repair or replace
Pump non - suction pressure gauge pointer to beat violently Insufficient water supply for perfusion, air leakage at the connection between pipeline and instrument Check pipeline and bottom valve, refill water diversion. Tighten air leakage

The pump consumes too much power

 

Too much flow, impeller wear

 
Check whether the pump shaft is bent, replace the impeller, close the outlet valve to reduce the flow
