Chapter 1 The introduction of PR5300 soft starter
1-1.The feature of the PR5300 soft starter
PR5300 series intelligent motor soft starter is the integration of new equipment for the new
motor control theory and specialized motor protection technology and advanced software
technology, is early for starting motor star /delta conversion and self coupling voltage, magnetron
step-down starting equipment, the ideal alternative products; its performance is currently on the
market most without the use of intelligent control technology of ordinary soft starter incomparable
starting. PR5300 series products are soft starting device for motor soft starting and on line
operation control.
1-2.The main function of the PR5300 soft starter
First: To reduce the motor starting current and reduce power distribution capacity, avoid
investment of expansion of power capacity.
The second: To reduce the starting stress of the motor and the load of the equipment ; extend
lifespan of the motor and related equipment.
Third: Its soft stop function can effectively solve the problem of parking vibration of the
inertial system,which is unable to realize by traditional starting equipment.
Fourth: To have six unique start-up modes adapts to the complex conditions of motor and
load, to perfect start effect.
Fifth: Has the perfect and reliable protection function; effectively protect the motor and the
related production equipment use safety.
Sixth: Motor soft starter intelligence, and network technology application makes motor
control technology to adapt to the rapid development of the electric power automation
technology in higher requirements.
1-3.The main features of the PR5300 soft starter

Terminal 5
The soft starter is closed when it fails or loses power, and it
is open when it is working properly. It is an passive contact.
The contact capacity is: AC250V/5A.
Terminal 6
Halt
Terminal 7
When the soft starter is working properly, this Terminal
must be short-connected to terminal 10. If this terminal and
terminal 10 are open, the soft starter stops working
unconditionally and is in failsafe state. This terminal can be
controlled by the normally closed output point of the
external protection device. When setting item PA to
0(Primary protection), this terminal function is disabled.

Terminal 8
The terminals 8, 9, and 10 are external control start and stop

(1)Programmable state output to indicate the working state of the soft starter, the time set by
P4 is invalid in this mode. The factory setting of PE is 7, which indicates the preparation state of
soft starter, can start the motor in this state; programmable output is in the failure state, which
indicates the fault of the motor (Err05, Err06, Err07, Err08, Err12, Err15), which is different from
the function of ⑤, ⑥fault output terminals; running state refers to non preparation or fault
condition, which includes 3 process of start, bypass, soft-stop.
(2)When PE> 9, the reset state of the programmable output (③, ④No. External pin) changed
from normally open to closed, that is inverted output. Flexible using the function of programmable
relay output, which can effectively simplify the external control logic circuit.

closed state before power on, soft starter will not respond the command , you must cancel the
running command by one time ,then give it run command again to make the soft starter work.
When soft starter fault reset, continuous running command is valid. Soft starter will not
respond the running command, you need to removed running command and then the running
protection state is canceled.
State 2:The electrical terminal running protection is invalid: the motor will start automatically
when the external control terminal in the closed state with power on , this is to say allow power on
start.
State 1 is shorted the 2, 3 of J14; state 2 is shorted the 1, 2 of J14.

PC is the selection of allowing to modify parameter, there are three options:
1) PC is set to 0, it is prohibited to modify any parameter .

Chapter 6 Protection and description
PR5300 series soft starter with complete protection to protect the safety of soft starter and
motor. During the application, appropriate protection parameters and level should be set based on
different situation.
6-1.Protection functions and their parameters
6-1-1.Soft starter over-temperature protection: The temperature rose to 80 ℃±5 ℃over-
temperature protection, when the temperature dropped to 55 ℃(the lowest), no over-temperature
protection.
6-1-2.Input phase lose protection delay time : <3 seconds.
6-1-3.Input phase lose protection delay time: <3 seconds.
6-1-4.Three-phase unbalance protection delay time: <3 seconds. It is based on the deviation of
all phase current greater than 50% ±10% . When the load current is lower than 30% of the nominal
rating of soft starter, the deviation will increase.
6-1-5.Over-current protection time during soft starting: Continuous 5 times greater than the
maximum operating current of the protection time set byp6 in Table 6.1.
6-1-6.Time of running overload protection: Continues 5 times greater than the load regulation
of the protection time setted by P6 in Table 6.1 .
6-1-7.The protection lag time of much too low supply voltage, when the power supply voltage
is lower than the 40% of limit, the protection time <0.5 seconds, or the protection time <3 seconds
if it is lower than the setting value.
6-1-8.The protection lag time of much too high supply voltage : When the power supply
voltage is lower than the 140% of limit, the protection time <0.5 seconds, or the protection time <3
seconds if it is higher than the setting value.
6-1-9.The protection delay time of load short-circuit : <0.1 seconds, the current is 10 times
more than soft starter nominal rated current. This protection can not replace fuse short-circuit
protection device.
6-1-10.Motor under load protection, the current range is 10% to 90% of motor rated current,
the protection action delay from 5 to 90 seconds.
These time parameters are from tested effective signal to a tripping protection instructions,
and the parameters just for reference. All the protection functions of PR5300 series soft starter can
be verified through the actual or simulation method. If it can't meet the user's requirements, special
protection device should be added to ensure safety.
6-2.Protection level setting description
6-2-1. In order to adapt to different applications, PR5300 series soft starter has five protection
level, there are 0: Primary, 1: Light load, 2: Standard load, 3:Heavy load, 4: Advanced, it set by PA
parameter. Among them:
1) Primary protection is against to the function of external terminal instantaneous stop,
meanwhile only remains the overheating, short circuit and main circuit fault protection, it can
be applied to needed emergency start in unconditional occasion, such as fire systems, etc.
2) The three protection level of light load, standard load and overload have the complete
protection function. The difference is the time curves of motor overloaded thermal protection
are not the same. The time parameters of motor thermal protection are as Table 6.1 and Figure
6.1. 3) High level of protection standards is stringent at start. Other protection features
parameters keep the same with standard protection set.
6-2-2. Protection level and thermal protection time according to PA setting is as the diagram
below:
