Rate CurrentRate Current
The Rate Current indicate that the output current of the soft starter at the
rate power. This parameter changes with the output power of the soft
starter. For detail see chapter 10. The methods shows below.

9.8 Working State9.8 Working State
When the soft Starter is power on, self-inspection is performed. The
self-inspection includes: test the parameters that the user changed (
parameters wrong protection), check if the phase of voltage is not right
( phase lack protection ) and check if the system temperature is too
high ( overheating protection ) etc. Any fault is detected, the system
immediately enter Fault mode. If no fault is detected, the system
enter the Ready state, and shows on the keyboard panel. At the
same time, the lamp on the left of the keyboard is light, it shows which
start mode is.

When soft starter is in the Ready state, press the key and keep

When soft starter is in the Ready state, and it is allowed to start the
motor, then user can press key to start the motor according to the
starting mode user set. At the same time, current value shows on the
keyboard. At the process of Starting or running, user can press the
key at any time to stop the motor, and then the system enter Ready
state.
In this state, the system monitors the parameter voltage phase, high
current suddenly, the time of starting and the system temperature etc.
So when the motor is running, soft starter can protect motor.

So when the motor is running, soft starter can protect motor.
When soft starter is on the process of Starting, Operating and Ready
state, system monitor all the protect parameter. If the value f mea-
sured is over the limited value user set, the trigger signal of the SCR
module is blocked, system enters the Fault state. Fault code shows on
the keyboard. The explain of the fault code introduce in the chapter
12.1 fault display explanation and solutions
