NORDAC SK 1xxE SAFETY NOTES Safe operation of the device requires that it is mounted and made operational by qualified personnel according to the instructions provided in this manual. Qualified personnel paying special attention to the safety and warning notes may only make adjustments. Special attention must be paid to the general and regional installation and safety regulations for work on high-voltage installations (e.g., EN, VDE) as well as to the directions for the proper use of tools and the utilization of personal protection devices.
NORDAC SK 140E 2 Electronic Motor Starter SK 140E 2.1 Principle of function The SK 140E enables a simple motor startup in one direction. The switching process takes place through 2 wear-free power switches. The activation or release of the drive occurs through a 24 VDC control signal.
The SK 140E-1-O (Mat. No. 275101400) is a motor starter without permanently integrated rectifier. However, it is possible to install any rectifier by Getriebebau NORD. This can be utilized in case of retrofitting or at system voltages of < 380 V. Spacer bolts are used for the assembly of the rectifiers. ( See also chapter 5.1 )
NORDAC SK 140E 2.3 Electrical connection Power cable: The system connection shall be performed with a cable of sufficient cross-section (max. 4 mm Control unit: 4-pole plug with screw terminals 1.5 mm (electrically separated from the system potential) PTC resistor/brake: 3 x 2-pole screw terminals with 1.5 mm (on system potential) Cable entry: The following are available: 1 x M25 and 1 x M12 and 1 x M16.
NORDAC SK 140E 2.4 Display and settings The following controls are available for the SK 140E: Transparent screw plug Status LEDs Slide switch To permit viewing of status (red / green) (Automatic ON/OFF LEDs from outside 2.4.1 Status LEDs These LEDs are visible through a lateral transparent screw plug. red LED: no fault present Blinking briefly...
NORDAC SK 150E 3 Electronic Soft Starter SK 150E 3.1 Principle of function The SK 150E allows a soft start-up and run-down of a three-phase asynchronous motor by a gradual rise or reduction of the torque to be defined. A smooth start-up is thereby achieved, preventing damage to the drive elements by a suddenly applied torque.
The SK 150E-1-0 (Mat. No. 275101500) is a soft starter without permanently integrated rectifier. However, it is possible to install a rectifier by Getriebebau NORD. This can be utilized in case of retrofitting or at system voltages of < 380 V. Spacer bolts are used for the assembly of the rectifiers. ( See also chapter 5.1 )
NORDAC SK 150E 3.3 Electrical connection Power cable: The system connection shall be performed with a cable of sufficient cross-section (max. 4 mm Control unit: 4-pole plug with screw terminals 1.5 mm (electrically separated from the system potential) PTC resistor/brake: 3 x 2-pole screw terminals with 1.5 mm (on system potential) Cable entry: The following are available: 1 x M25 and 1 x M16 and 1 x M12.
NORDAC SK 150E 3.4 Display and settings The following controls are available for the SK 150E: Transparent screw plug Status LEDs Slide switch Potentiometer Dip switch (red / green) (Automatic ON/OFF) (Torques/Times) (Operating To permit viewing of mode) status LEDs from outside 3.4.1 Status LEDs These LEDs are visible through a lateral transparent screw plug.
NORDAC SK 150E 3.4.2 Setting the potentiometers and dip switches With the electronic soft starter Sk 150E, the start-up and run-down behavior of the drive can be adapted to the respective application. The settings are made using 4 dip switches and 4 potentiometers.

NORDAC SK 150E Operating mode "01" These and the subsequent operating modes work with an "increased initial breakaway torque" during start-up. System That means, an increased (in some voltage cases, possibly also a reduced) torque is realized during start-up at the motor for an adjustable time.
Page 15
NORDAC SK 150E The following table provides an overview of all dip switches and potentiometers as well as the corresponding description of the functionalities. Switch Function Setting Description The drive starts with a predefined torque and start-up time. Torque and time can also be set for the run-down.

NORDAC SK 150E DIP switches The 4 existing dip switches are used to set the operating mode and the adjustable time range of a potentiometer. The following table provides an overview for the setting of the operating mode as well as the corresponding assignment of individual functions, potentiometers and time ranges.
NORDAC SK 150E Potentiometers With the 4 potentiometers, the user can adjust the different times and torques infinitely variable, depending on the operating mode. After the operating mode and the time range have been set with the dip switches, the following table can be used to set the respective function of the potentiometer and the pertaining time range.
NORDAC SK 160E 4 Electronic Reversing Starter SK 160E 4.1 Principle of function With the SK 160E, a motor can be switched in both directions. For protection purposes, there is a locking time for the immediate reversal that can be set with 2 rotary dip code switches.
The SK 160E-1-O(-C)-3D-T125 is motor reverse starter without a fixed integrated rectifier. However, there is the possibility of installing a rectifier from Getriebebau NORD. This can be used in case of an upgrade, or for mains voltages < 380V. Spacer bolts are provided for installing the rectifier. ( See also Section.
NORDAC SK 160E 4.3 Electrical connection Power cable: The system connection shall be performed with a cable of sufficient cross-section (max. 4 mm Control unit: 5-pole plug with screw terminals 1.5 mm (electrically separated from the system potential) PTC resistor/brake: 3 x 2-pole screw terminals with 1.5 mm (on system potential) Cable entry: The following are available: 1 x M25 and 1 x M16 and 1 x M12.
NORDAC SK 160E 4.4 Display and settings The following controls are available for the SK 160E: Status LEDs Slide switch Rotary dip code Transparente screw switch plug (red / green) (Automatic ON/OFF) (Reverse locking time) To permit viewing of status LEDs from outside 4.4.1 Status LEDs These LEDs are visible through a lateral transparent screw plug.
NORDAC SK 160E 4.4.2 Rotary dip code switches for locking time With the help of two 10-step rotary dip code switches, the user can select the locking time for direct direction reversal. Both electronic power switches are locked for this time. The switch (P1) is used to select the desired time range.
This separate brake rectifier may be required for supply voltages smaller than 380 V or when a bridge rectifier is used. More information on brake rectifiers on drives by NORD can be found in the electric motor catalog M7000/3 DE. Type designation: Mat.
