  • Page 18 about 15%. （ ）The action time of tE protection is achieved by setting "motor type" and "trip level", and the corresponding trip curve is selected by setting tEp (trip level) according to Table 9.(When the motor type is selected as "increased security motor", the tripping level will automatically change to tEp setting;Otherwise, the trip curve is the reverse time-limit overload trip curve of ordinary motor.
  • Page 19 6.3 Locked-rotor protection In the process of starting, if the motor shaft is stuck due to excessive load or mechanical reasons, and the fault is not removed in time, the motor will overheat and the insulation will be reduced and the motor will be burned out.The locked-rotor protection is applicable to the motor when such faults occur in the starting stage.

  • Page 28 Note: Ts1: Delay time of alarm action Ts2: Delay time of trip action 6.20 Overflow protection When the fault occurs, the current exceeds the breaking current of the contactor, and the contactor will be damaged if the contactor is forcibly disconnected.At this point, the breaker should be broken first, and then disconnect the contactor after the fault current is removed.
  • Page 29 Example: Set the time limit of 1 hour to allow 3 starts. Figure above: It has been started for 3 times between 13:00 and 14:00, and there is no number of starts at the fourth time, so the fourth time fails. Figure below: Before the fourth start, the remaining number of starts is restored to 1, so the fourth start is successful.
