NORDAC SK 1xxE

1 General description

The product series NORDAC SK 1xxE constitutes a motor or wall-mounted electronic component that can be
used to handle simple drive or switching functions. The following types are part of this product series:

SK 140E Electronic motor starter

(Startup in one direction)

SK 150E Electronic soft starter

(Soft startup and run-down with adjustment of time and torque)

SK 160E Electronic reversing starter

(Startup possible in both directions)

The electronics of this motor starter series are integrated into the motor's terminal box. They can be directly
mounted on top of the motor (motor-integrated) or on the wall (proximity of motor). Each starter possesses an
assessment of a thermal protector (temperature probe or control) and an optional brake rectifier. A red or a
green LED visable from the outside through a transparent screw plug, indicating the devices status.

The NORDAC SK 140E enables a switching operation of a three-phase asynchronous motor in one direction.

This allows for cost-efficient switching directly at the drive.

The NORDAC SK 150E enables a soft start-up and run-down of three-phase asynchronous motors. This

allows for starting and stopping of the drive smoothly. With the soft starter, both torque and times can be set
separately for the startup and rundown of a drive.

The NORDAC SK 160E enables the switching operation of a three-phase asynchronous motor in both

directions. 2 rotary dip code switches are used to set a locking time to protect the installation against damage
caused by too quick a reversal.

The entire power range of the motor starter series is covered by one component size. The power range of the SK
140E reaches from 0.12 kW to 3.0 kW, that of the SK 150E and SK 160E cover a range from 0.12 to 4.0 kW.

Motor sizes 80 to 112 (with the SK 140E up to size 100) allow for direct mounting; sizes 63 to 71 require a simple
adapter plate (Mat. No. 11015410).

The number of poles of a motor is immaterial; the only determining variable for the motor starter are the power
consumption and the motor size.

The control electronics require 24 VDC (15 ...30 VDC, ≈ 50 mA) supply voltage, e.g., from a PLC or another power
supply.

Optionally, each SK 1xxE is available with an integrated fast acting rectifier (BSG2). The electromechanical brake
can then be directly connected to the device; no additional supply voltage is required for the brake.

A bus access is possible for all electronic starters of the SK 1xxE series by means of an optional AS interface
(AS1).

With the option (MS) there is the possibility of realising the power input or motor output of the starter by means of a
system plug of the Harting HAN 10E type.

All devices of the SK150E/160E series in the versions with and without integrated brake rectifiers fulfil the
requirements for explosion protection (ATEX) in Zone 22 according to the currently valid standards according

to EN 50281 (Guideline 94/9/EG). However, this only applies if no further add-on options (AS interface, plug
connectors) are included.

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.

The motor connection terminals may carry dangerous voltage even at standstill of the motor (e.g., through
electronic lock [RUN] or blocked drive). A motor standstill is not equivalent to electrical disconnection from
system power.

ATTENTION: Touching open or exposed terminals can lead to serious injuries or death! Always use

insulated screw drivers on these terminal panels. Make sure that the input voltage source is without voltage
before you make connections to the unit or prior to altering them.

ATTENTION: The drive may start running immediately after applying system voltage.

1.1 Delivery

Inspect the device immediately after receipt/unpacking for transport damages such as deformed or loose parts.

In case of damage, contact the freight carrier without delay; initiate a careful fact-finding measure.

Important! This also applies if the packaging is not damaged.

1.2 European EMV (EMC) guideline.

If a NORDAC SK 1xxE is installed according to the recommendations of this manual, it will
meet all requirements of the EMC guideline being in conformity with the EMC product
standard EN60947-4-2 for low voltage switching devices, semiconductor control devices and
starters for alternating current..

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
integrated temperature monitoring can be done via a
temperature probe or control. A design with a rectifier ­integrated or separately installed in the terminal box – is
available for the control of a brake.

Features:

• The SK 140E contains an electronic power switch that switches the supply voltage to the motor

windings via a 24 VDC control signal [RUN].

• At the same time, the electromechanical brake (if present) is released through the integrated brake
rectifier (option).

SK 140E

• If the control signal is canceled, the supply of the motor windings is interrupted and the brake (if
present) is applied again.

• During the entire operation, the motor can be thermally monitored through temperature probes acting

as overload cutout. There are 2 monitoring modes that can be selected by means of a slide switch.

During automatic operation (slide switch set to [ON], the SK 140E switches the motor off automatically
and reports the excess temperature by removing the OK message (fault signal, signal [OK] changes to
low). If the automatic operation has not been selected (slide switch set to [OFF]), then only the OK
message is removed and the drive continues to run. The inputs must be connected with a jumper if
temperature monitoring is not desired.

• In automatic operation, the motor does not automatically start even after cooling. To restart, the

control signal [RUN] must first be switched off and then on again. Alternatively, the internal slide switch

can be switched [OFF] and [ON] again. Caution, the drive starts immediately!

• The basic direction is predetermined by the system input phases. This can be altered by exchanging

2 phases. For the correct phase sequence, [RUN] corresponds to a clockwise motor direction.

• The current status of the SK 140E is shown through 2 LEDs. These are visible from the outside

through a transparent screw plug.

2.2.1 SK 140E-1-O

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. (Æ See also chapter 5.1 )

2.2.2 SK 140E-1-BSG2

The design with integrated fast acting brake rectifier has the designation SK 140E-1-BSG2 (Mat. No.

275101405). With this device design, a fast acting brake rectifier has been added to the basic function to
directly control a brake mounted to the motor. Consequently, the brake voltage supplied equals supply voltage
x 0.45. The jumper [L] can be used to affect a gradual switch-off by shorting the integrated DC switch. (Æ See
also chapter 5.1 )

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. A 2-phase control
process realizes the drive properties. The selection or
release of the drive occurs through a 24 VDC control
signal. Depending on the operating mode chosen, the
start-up and braking torque as well as the associated time
can be adjusted with potentiometers. 4 slide switches
define the operating mode. The integrated temperature
can be monitored via a temperature probe or control.
For the activation of a brake, a design with a
rectifier - integrated or separately installed in the terminal
box – is available.

SK 150E

Features:

o A 24 V voltage supplies the control electronics externally. The control logic is potential-separated

from the system voltage.

o With the release of the drive via a 24 V control signal, the motor is supplied with voltage through a

phase control process. If an integrated brake rectifier is included, then it is connected to the system

voltage through electronic power switches and the electromechanical brake is thereby released.

o During the entire operation, the motor can be thermally monitored through temperature probes (PTC

resistor or temperature control) thereby acting like an overload cut-out. There are 2 monitoring
modes that can be selected by a slide switch. During automatic operation (slide switch set to [ON]),

the SK 150E switches the motor off automatically and reports the excess temperature by removing the
OK message (fault signal, signal [OK] changes to low). If the automatic operation has not been
selected (slide switch set to [OFF]), then only the OK message is removed and the drive continues to
run. The inputs must be connected with a jumper if temperature monitoring is not desired.

With automatic operation, the motor does not automatically start even after cooling. To restart, the

control signal [RUN-RIGHT] must first be switched off and then on again. Alternatively, the internal

slide switch can be switched [OFF] and [ON] again. Caution, the drive starts immediately!

o The basic direction is predetermined by the system input phases. This can be altered by exchanging

2 phases on the motor terminal board. With the correct phase sequence (U1, V1, W1), [RUN]
corresponds to a right motor direction.

o The current status of the SK 150E is shown through 2 LEDs. These are visible from the outside

through a transparent screw plug.

o Series SK 150E in the versions SK 150E-1-0 and SK 150E-1-BSG2 fulfils the requirements for

explosion protection (ATEX) in Zone 22 according to the currently valid standards according to EN

50281 (guideline 94/9/EG).

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.

The dip switches 1 and 2 are used to set 4

different operating modes. The dip switches 3
and 4 determine the time base for two
potentiometers.

The potentiometers are used to set times

and torques for drive characteristics.
Depending on the operating mode set,
potentiometers P1 and P3 are for the
associated torques and potentiometers P2
and P4 for the corresponding times.

Operating modes

4 different operating modes, i.e., characteristics during start-up and run-down, can be selected with the
electronic soft starter SK 150E. If a drive with SK 150E shall be started, then the operating mode must first be
determined, followed by the setting of the associated torques and times. The principle of the phase control
must always be observed, by which the variable torque is merely determined by the voltage applied to the
motor. This does not allow ramp times and torques to be realized with the same quality as with a frequency
inverter.

The 4 operating modes are described and explained below. The pertaining dip switch positions and adjustment
ranges can be taken from the subsequent chapters. All information supplied on brake properties presuppose a
brake motor as well as the SK 150E with integrated or separate rectifier.

Operating mode "00"

With this operating mode, the
torque (voltage on motor, P1)
and the time (P2) can be set for
start-up and run-down.

When applying the release
[RUN-R], the drive starts up
with the torque (voltage at
motor) set at P1. The maximum
torque (full voltage at motor) is
reached after the time set at
P2.

When removing the release
signal [RUN-R], the torque
(voltage at motor) is lowered
immediately to the value set at P3. The torque is then reduced continuously in the time set at P4 until standstill.
The brake applies after the run-down of the time set with P4.

torque (or voltage) set with P3 can be

is reduced to the value set at P1. The starting ramp begins here and reaches the maximum moment (full
voltage at motor) after the time set in P2. This time also applies to the run-down ramp after removing the
release [RUN-R].

Operating mode "10"

This operating mode only differs from
the previous "01" by the switch-off
characteristics. After removing the
release [RUN-R], the voltage is
switched off at the motor causing the
drive to coast to a stop. The brake
applies only after the time set at P2
elapses.

Operating mode "11"

Again, this operating mode differs
from the previous "10" only in the
point in time when the brake becomes
active. If at "10" some time first
elapses then here the brake applies
immediately after removing the
release [RUN-R]. The drive cannot
coast to a stop.

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.

Note:

It must be observed that times and torques of a soft
starter can only be adjusted under the load conditions of the
application to be realized. Accordingly, the time ranges in
seconds only apply under load. The scales serve as
benchmarks and are not to be considered defined values in sec.
and Nm.

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 selection or release of the drive
occurs through a 24 VDC control signal. The integrated
temperature can be monitored via a temperature probe or
control. A design with a rectifier - integrated or separately
installed in the terminal box – is available for the
activation of a brake.

SK 160E

Features:

o The SK 160E contains power switches that are activated via a 24 VDC control signal [RUN-RIGHT]

or [RUN-LEFT] and pass the system voltage to the motor windings.

(RUN-RIGHT = Right running (clockwise), RUN-LEFT = Left running (counterclockwise))

o 2 rotary dip code switches determine the locking time in case of direct direction reversal.
o At the same time, the electromechanical brake (if available) is released through the integrated brake

rectifier (option).

o If the control signal is removed, the voltage supply of the motor windings is interrupted and the brake

(if present) is applied again.

o During the entire operation, the motor can be thermally monitored through temperature probes acting

like an overload cut-out. There are 2 monitoring modes that can be selected through a slide switch.
During automatic operation (slide switch set to [ON]), the SK 160E switches the motor off

automatically and reports the excess temperature by removing the OK message (fault signal, signal
[OK] changes to low). If the automatic operation has not been selected (slide switch set to [OFF]), then
only the OK message is removed and the drive continues to run. The inputs must be connected with a
jumper if temperature monitoring is not desired.

o In automatic operation, the motor does not automatically start even after cooling. To restart, the

control signal [RUN-RIGHT] or [RUN-LEFT] must first be switched off and then on again. Alternatively,

the internal slide switch can be switched [OFF] and [ON] again. Caution, the drive starts immediately!

o The basic direction is predetermined by the system input phases. This can be altered by exchanging

2 phases. For the correct phase sequence, [RUN-RIGHT] corresponds to a clockwise motor direction.

o The current status of the SK 160E is shown through 2 LEDs. These are visible from the outside

through a transparent screw plug.

o Series SK 160E in the versions SK 160E-1-0 and SK 160E-1-BSG2 fulfil the requirements for

explosion protection (ATEX) in Zone 22 according to the currently valid standards according to EN

50281 (Guideline 94/9/EG).

4.2.1 SK 160E-1-O(-C)-3D-T125

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. (Æ See also Section. 5.1 )

4.2.2 SK 160E-1-BSG2(-C)-3D-T125

The version with integrated rapid-switching brake rectifier has the designation SK 160E-1-BSG2(-C)-3D-T125.
With this version of the device, a rapid switching brake rectifier is fitted in addition to the basic function, in order
to directly control a brake which is mounted on the motor. The output braking voltage is then the mains voltage
x 0.45. With the jumper [L], slow braking can be switched to by bypassing the integrated DC switch. (Æ See
also Section 5.1 )

4.2.3 SK 160E-1-x(-C)-MS

The reverse starter can be equipped with a Harting HAN 10E plug connector. The configuration in the terminal box
is described in Section 5.3). According to the version (without or with an integrated brake rectifier) the
corresponding designation is SK 160E-1-0(-C)-MS or SK 160E-1-BSG2(-C)-MS.

4.2.4 SK 160E-AS1-x(-C)-MS

In the versions described under 4.2.1 to 4.2.3, the reverse starter SK 160E can be extended by the AS
interface bus access (SK IU2-AS1) option, using an additional assembly integrated into the cover of the
housing. (Æ See also Section 5.5.1).

In combination with a HAN 10E system plug it is also possible to integrate the AS interface bus access into the
SK 160 E by modifying the terminal box. With this version of the reverse starter the plug connector is mounted
flush left on the terminal box and not in the centre. The feed-out of the connecting sockets of the AS interface
is then carried out according to Section 5.5.2 next to the plug connector, and not via the cover of the terminal
box.

This version of the SK 160 E is available both with and without an integrated brake rectifier. The designation
for these versions is accordingly SK 160E-AS1-BSG2(-C)-MS or SK 160E-AS1-O(-C)-MS.

5 Options / Accessories SK 1xxE

5.1 SK 1xxE on motor with electromechanical brake

When operating an SK 1xxE in conjunction with a brake motor, there are different options to generating the coil
voltage of the brake. An SK 1xxE with integrated brake rectifier can be used or – e.g., in case of special
voltages – an SK 1xxE with separately installed rectifier.

5.1.1 SK 1xxE with integrated brake rectifier

All SK 1xxE with integrated brake rectifier receive –BSG2

(e.g., SK 140E-1-BSG2) as corresponding suffix in the type
designation. A fast acting rectifier (BSG/brake control, half­wave rectifier) is integrated here in the electronics. The output
brake coil voltage (terminals [Br-] and [Br+]) depends on the
supply voltage of the drive.

Supply voltage 400 VAC Æ Brake voltage 180 VDC

Supply voltage 480 VAC Æ Brake voltage 205 VDC

A separately installed brake rectifier must be used for supply
voltages smaller than 380 V.

The bridge [L] allows conversion to a gradual switch-off.

Bridge [L] open Æ Direct current switch-off, quick cut-in

Bridge [L] closed Æ Alternating current switch-off, gradual cut-in

5.1.2 SK 1xxE with separately installed brake rectifier

If a separate brake rectifier is contained in a SK 1xxE, the suffix -O (e.g. SK 140E-1-O) is included in the type
designation. No terminals are available here for brake activation. If an electromechanical brake needs to be
activated, a separate rectifier can be mounted on inserted spacers. 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.
