The list of rated power for SJR3-2000 series soft starter
Inspection and preparation before running:
The following should be inspected and prepared before starting running
1) Check if the connections are correct or not, particularly, the output terminals should not be connected to the power, and confirm if the grounding terminal is well grounded or not.
2) Confirm theres no short circuit or short circuit to earth between the terminals or the exposed live parts
3) Upon the power is connected, the keyboard panel shall display(Zhejiang Saikong )or [ready] status.
Running method:
Select appropriate operation method as required, the soft starter is set to be panel controlled when delivery
◎ Upon the power is connected, the keyboard panel shall display(Zhejiang Saikong )or ready status, press the start button, the motor will be started.
◎ Input setting entry FP according to the rated current value on the name plate of the motor.
◎ Upon start, check if the rotation direction of the motor is correct or not, if no, press the stop button to stop the motor or cut off the power if necessary, then switch any two wires of the motor(U1, V2, W3)
◎ If the motor fails to reach good start status, refer to the section of starting mode and application of the soft starter in page 12 to select proper settings
◎ If the torque fails to reach good effect, change the starting voltage code F0(under voltage mode)or current limiting code F5(under current mode)to increase the start torque of the motor
◎ Once power of the soft starter is on, please do not open the cover, otherwise there maybe risks of electric shock.
◎ In the process of trial running after power on, if there's any abnormal phenomenon, such as abnormal sound, smoke or odor, please cut off the power immediately and find out the causes.
◎ Press the stop button or external control stop button to reset the fault status.
Note: when the ambient temperature is below-10 C, please get the power on and start the soft starter after preheating for 30mins
