Overload control protection

when the motor is overload,the over current will be calculated according to the motor heat capacity tracking.Fully considered the motor rotor and stator’s temperature rise and the influence to the motor heating because of the three-phase unbalance.When the current reached the control protection value,the device will do the alarming and notice the shutdown delay time.

Underload protection

when any one of the three-phase current is lower than the set underload value,the device will do the alarming and notice the shutdown delay time.

Locked-rotor protection

when the current value reached the set current multiples,the protection device will do the alarming and notice the shutdown delay time.

Three-phase current unbalance protection

when the ratio of the minimum phase or the maximum line current reaches or exceeds the set value, the protection device will do the alarming and notice the shutdown delay time.

Open-phase protection

It will be judged as open-phase fault if any one of the three-phase current’s ratio is not bigger than the unbalanced angle value, the device will do the alarming and notice the shutdown delay time.

Overvoltage protection

The protection device and the measure device monitor the three-phase voltage value, the device will do the alarming and notice the shutdown delay time if the equipment’s largest voltage is higher than the set value.

Undervoltage protection

The protection device and the measure device monitor the three-phase voltage value, the device will do the alarming and notice the shutdown delay time if the equipment’s smallest voltage is lower than the set value.

Leakage (earth)protection

Judge the leakage fault by using the zero sequence current transformer to measure the protective conductorPEor PEN’s short-circuit leakage current value.When the short-circuit leakage current value is bigger than the set leakage value, the device will do the alarming and notice the shutdown delay time.

Electric shock protection

The protection device monitors the equipment’s voltage continuously, when the system voltage recovered after the moment dropped,the motor can start again.

Timeout protection

The protection device inspects the start-up current delay time,when the equipment can bot be started up within the start-up delay time,and the three –phase current is 1.2 time bigger than set current,the timeout protection will function and the power will turn off.

Reversal protection

When the protection device monitored the three-phase voltage sequence is not correct,the equipment can not start-up.

External fault protection

When the device monitored the external switching value input signal is different from the device’s set switching value input signal,the device can not be started up.

  Typical wiring

  

  Installation size

  

  

 

  Forward and reverse start control

  In this mode,The device controls the relay 1 to make the motor forward and the relay 2 to make the motor backward.When the device received stop command or any protection action,it will transmit the stop command to the relay 1 and relay 2 to stop the motor function.

  

  Direct start control

  Direct start is the equipment’s basic start type.When the device received the fieldbus or“I/O” start signal, output relay’s contact point will control the 1 closed.When the device received stop or any protection signal,the contact point will control the 1 opened.

  

  Direct bypass start control

  When the device received the fieldbus or “I/O” start signal,the output control relay 1 will output a pulse closing signal.When the device received the stop or any protection signal,the output control relay 3 will output a pulse closing signal to open the direct bypass start mode,the operation screen will not work soon, and can start or stop the motor through the external button.

  

  Star-triangle start control

  The equipment is in star shape wiring before be started, When the start current is below 1/3 of the triangle shape wiring’s current and the start torque is also below 1/3 of the triangle shape wiring’s torque,the equipment will begin the star step-down start and will do the star-triangle transformation if reached the transformation time,Then it will function in triangle wiring mode.

  Need to follow the principles when setting parameters:change-over time(start time,the star -triangle transformation must be completed before the equipment is started up).

  

  Autotransformer step-down start control

  As the name implies, the equipment is started through the autotansformer step-down.The reduction of the start voltage aims at reducing the start current,and the start torque will also reduce at the same time.

  Need to follow the principles when setting parameters:change-over time(start time,the transformation must be completed before the equipment is started up).
