General of WKR5000S Series Chinese Display Double-screen Motor Soft Starter |
WKR5000S series double-screen intelligent motor soft starter is suitable for
three-phase AC squirrel-cage asynchronous motor of AC380V -1140V, 50(60)Hz and
rated current 1200A and below. This motor soft starter is of device type, it is
required to add circuit breaker (for short-circuit protection purposed) and AC
contactor (bypass purposed after starting is finished) inside the cabinet, and
formed into motor control circuit with switch.
WKR5000S series of products adopts double-screen display that is convenient for
operating and using, the liquid crystal display and digital display employ
different communication channel; the product does not need heating relay, there
are perfect motor protection functions both in motor starting and running
process; it adopts closed-loop control that sharply improves smoothness and
reliability of soft moment starting and soft moment stop; it introduces bypass
contactor, running power nears zero, it not only improves reliability of
product, but also reduces its outline dimension.
WKR5000S series of soft starters ranks the leading position in double-screen
display with complete functions, its properties are far ahead of those common
type soft starters that do not adopt intelligent control technology, launching
of WKR5000S series of soft starters emblematizes a new step of our country in
development and application of motor soft starter. |

Service Condition of soft starter |
01、Installation site should be in compliance with the following service
conditions and installation methods, otherwise, it is difficult to guarantee the
performance of WKR5000S motor soft starter, the service life of soft starter
would be reduced, the soft starter even would be damaged.
02、Mains voltage: AC 380V-1140V, 50/60HZ.
03、Applicable motor: squirrel cage three-phase asynchronous motor, rated power
of motor should be matched with the rated power of soft starter.
04、Starting frequency: not over 15 times per hour.
05、Cooling mode: natural air cooling .
06、Degree of protection: IP20
07、Ambient temperature: -30 ℃ ~ +55℃
08、Ambient humidity: relative humidity not exceed 95%, no condensation
09、Service place: draughty, free of corrosive gas or conductive dust, vibration
should be lower than 0.5G.
10、Altitude: <3000m, if the altitude exceeds this height, please improve the
power of soft starter correspondingly. |

Applicable Industry |
Water pump-makes use of water hammer phenomenon releasing pump during soft stop,
saves system maintenance cost.
Ball mill-makes use of the ramp voltage start to reduce wear of gear torque and
maintenance workload, it not only saves time, but also saves cost.
Fan-reduces belt wear and mechanical shock, saves maintenance cost.
Compressor-makes use of rotation-clogging protection and quick protection
functions, preventing from motor burn out due to overheating caused by
mechanical failure or block.
Transfer mechanism-realizes smooth starting through soft start, preventing
product displacement or overflowing of liquid. |

Parameter setting & Description |
 |
Notes：
1、In setting state, if there isn't any key operation for over 2min, it would
exit the setting state automatically.
2、Operation of parameter setting can be carried out in any state except soft
start or soft stop state.
3、 Push down YES to start up, you are able to get back the set parameters
(except PD) to default value. |

WKR5000S series motor soft starter has two types of wiring method:
Wiring of main loop: including wiring of three-phase power inputting/outputting
main motor, wiring of circuit breaker and bypass contactor.
Wiring of control terminal: there are 12 miniature connection terminals for
leading out, including the control line of bypass contactor, control line of
ON/OFF switch, and analog output signal line. |

External terminals desciption of moto soft starter |
Terminals 1 and 2 are of passive normally open contacts, used for controlling of
bypass contactor, they will close after successful start.
Terminals 3 and 4 are for programmable time delay output, output function and
mode are determined by the set item PD, they are passive contacts.
Terminals 5 and 6 are for fault output, they will close when the motor soft
starter comes across troubles or power failure, and open in normal condition,
they are power contacts.
Terminals 7, 8, 9 and 10: form into the external control circuit; they are
passive contacts.
Terminal 10 is a common port
Terminal 7 is for instantaneous stop input: when 7 is disconnected from 10,
motor soft starter stops working. (Used for connecting with thermal relay NC)
Terminal 8 is for soft stop input: when 8 is disconnected from 10, it is soft
stopped. (Need not autolocking)
Terminal 9 is for soft start input: when 9 is connected with 10, it is soft
started.(Need not autolocking)
The above wirings are of three-wire control mode, when terminals 8 and 9 are
connected in parallel and used as one terminal, they are able to start once
connecting with 10, and stop once breaking, they can be applied to a relay
contact to control start/stop, this is two-wire control
Terminals 11 and 12 are 0~20mA DC analog output, max output resistance is 300Ω. |
