4.5 Main technical parameters of intelligent release

4.5.1 Start Delay

During the CPS start-up time, it only protects the lack of fuse, phase failure, overvoltage, undervoltage, undercurrent, short circuit, leakage and three-phase unbalance. To avoid the protection of high current and overcurrent when the CPS starts; the setting time is ( Choose between 1~99) seconds;

4.5.2 Overvoltage and undervoltage protection

Only the auxiliary supply voltage is protected to ensure proper coil operation.

Overvoltage protection: When the auxiliary power supply voltage exceeds the set value (factory setting is 120%Us), the action time is less than or equal to 10 seconds

Undervoltage protection: when the auxiliary power supply voltage is lower than the set value (factory setting is 75%Us), the action time is less than or equal to 10 seconds

4.5.3 Inverse-time-load long-delay protection

The user sets the rated working current le of the intelligent release according to the load current I, so that the load current I is between 80 and 100% le, and the action time is set according to the load characteristics. See Table 4 for the characteristics of overcurrent multiples and action time. Time limit overload long delay protection characteristic curve is factory set at F2

Table 4. Action characteristics of CPS inverse-time overload long-time protection

Overcurrent times	time（S）	serial number（F）	1	2	3	4
l.0			no action	no action	no action	no action
≥1.1			5	60	180	600
≥1.2			5	50	150	450
≥1.3			5	35	100	300
≥1.5			5	10	30	90
≥2.0			5	5	15	45
≥3.0			5	2	6	18

4.5.4 Undercurrent Protection

Undercurrent protection: It is based on the ratio of the minimum current to the rated current to determine whether to activate the undercurrent protection (the factory setting is 60%). The working current le of the CPS intelligent release, so that the motor is not within the protection range of the CPS.

When the current is less than the set value of the undercurrent protection, the action time is less than or equal to 30 seconds.

4.5.5 Three-phase unbalanced (broken, missing phase) protection

Three-phase unbalance protection is based on the ratio of the difference between the maximum and minimum current to the maximum current to determine whether to start the three-phase unbalance (break, phase loss) protection

(Unsettling rate = (maximum current – minimum current>/maximum current)

When the difference of any two-phase current value exceeds 20~75% (the factory setting is 60%), the action setting time is less than or equal to 3 seconds.

4.5.6 Stall protection

Locked-rotor protection is to prevent the motor from heating and damaging the motor due to serious operation blockage of the driving equipment or overloaded operation of the motor. Generally, the working current reaches the set value to judge whether to activate the locked-rotor protection.

When the working current reaches 3.5~8 times of the rated current, the action time is less than or equal to 0.5 seconds.

4.5.7 Short circuit short delay protection

When the working current reaches more than 8 times of the rated current, the action time is less than or equal to 0.2 seconds.

五、 Product Operation Or Setting

5.1 Panel Display and Key Instructions

Before the CPS is energized and closed, the long-delay and short-delay setting currents should be set to the required values according to the line load current it controls and protects. After the power is turned on, the digital tube lights up, displays the auxiliary current and voltage value, and cyclically displays the monitored operating current value of the A, B, and C three-phase circuits.

5.2 Running operations

Setting key: When the load is not running, press this key to enter the state of parameter setting

Shift key: Select the set word bit in the setting state, and the selected word bit is in the blinking state

Data key: Modify the flashing word bit. The level difference is 1 {0 to 9 cycles}

Reset key: After the parameter setting is completed, press this key to save the parameter and put it into the normal monitoring operation state

5.5.1 After the CPS is connected to the working power supply, the LED displays the voltage value, which can also be used as a voltmeter, and the last three digits display the voltage value.

5.5.2 The CPS can also be used as an ammeter during operation to display the three-phase current operation in a cycle.

Press the “shift key” to directionally display the current extension status of A-phase, B-phase, C-phase and L (leakage).

Press the “reset key” to resume the cycle display of the three-phase current operation.

5.2.3 Troubleshooting

No-load operation of CPS, press the “data key”, compare with the fault type symbol on the panel, you can check the first three fault types; when the voltage value is displayed, it means

The CPS has exited the fault query and is put into normal monitoring operation status: or restart the CPS to exit the fault query

5.3 Protection parameter settings

When the motor starts and runs, pressing the setting key is invalid;

No-load running cps: press “set key” to select setting type, press “shift key” in turn, select data shift, press “data key” to modify data;

After a parameter is set, press the “set key” again to enter the next setting state, until the end;
