5. The main technical parameters of intelligent release
(1) Start Delay: In RSCPS start time, only the phase, phase failure, overvoltage, undervoltage, under current, short circuit, leakage and phase imbalance protection, in order to avoid large current RSCPS start and overcurrent protection; setting time for the selection of (1 to 99 seconds) between.
(2) overvoltage and undervoltage protection: only the auxiliary power supply voltage protection to ensure normal operation of the coil. Overvoltage protection: When the auxiliary power supply voltage exceeds the set value (factory setting at 120% Us), the operating time of ≦ 10 s; voltage protection: When the auxiliary voltage is lower than the current setpoint (factory setting at 75% Us) , operation time ≦ 10 seconds.
(3) inverse long delay overload protection: the user according to the load current I set intelligent release rated current Ie, the load current I between 80 ~ 100% Ie, the operation time is set according to the load characteristics, overcurrent multiples and operation time characteristics below. Inverse time overload long delay protection characteristic curve factory settings in F2.
(4) under current protection: In accordance with the smallest ratio of current and rated current to determine whether to start under current protection (factory set at 60%), can not be unloaded motor protection; the user does not have avoided according to the load current I setting RSCPS intelligent release operating current Ie, causing the motor is not within the scope of RSCPS. When the current is less than under current protection set value, the action time
(5) three-phase unbalanced (off phase) protection: phase unbalance protection is based on the ratio of the difference between the maximum and minimum current and maximum current to determine whether the starting phase unbalance (off phase) protection. Unbalance ratio = (maximum current – the minimum current) / maximum current. When any two-phase current values differ by more than 20 to 75% (factory set at 60%), Operate time
(6) stall protection: Stall protection is to prevent the motor drive apparatus severe blockage or motor running overload and heat damage to the motor, generally based on the current reaches the set value to determine whether to activate the stall protection. When the current reaches more than 8 times the rated current,
(7) short circuit short delay protection: When the current reaches more than 8 times the rated current, the action time ≦ 0.2 seconds.

RSCPS should be preceded with the power switch on the control and protection in accordance with the load current of the circuit long delay and the short time delay setting current set at a desired value. After power-lit digital display auxiliary current and voltage monitoring cycle to the A, B, C three-phase circuit operating current value.
2. Run Operation
After (1) RSCPS access to the power supply, LED displays the voltage value, can double as a voltmeter, after three show the voltage.
(2) RSCPS at runtime doubles as ammeter function cycle phase current operation. Press the “shift key” to show the orientation phase A, B phase, C, L (leakage) current operation; press the “reset button” to restore the operation of three-phase current cycle.
(3) Troubleshooting: load running RSCPS press the “key data” and the fault type symbol control panel, you can view the first 3 faults; the display to indicate voltage value out of the RSCPS troubleshooting, put into normal operation status monitoring; or restart RSCPS exit fault finding.
3. Protection parameter setting
When the motor is up and running, press the Set button is invalid;
Load operation RSCPS, press “Settings button” to select the type of setting, followed by “shift key”, select the data shift, press the “key data”, data modification;
A parameter setting is completed, press the “set key” to enter the next setting state, until the end;
The option should not need to give up setting all parameters have been set, exit the setting mode, the display voltage.
