Soft Start Drive Series SK 135E & SK 175EEliminate uncontrolled starting and mechanical strain on your drive components with the SK135E soft start drive family.

AC Motors that are connected directly to their power source exhibit a heightened power consumption during starting, stopping and can demand up to 7X of the rated motor current irrespective of load. This can create irregular starting and shut down behaviors as well as unneccessary strain on all components involved.

NORD has created a simple and economical solution to these unneccesary risks associated with running electric motors as your prime mover. The SK135E regulates the 3 major functions of a motor starter and controls them in order to protect your equipment and what you are moving while saving you money in the process.

SK 135E The SK 135E is a new decentralized product that is generally used for soft starting motors to aleviate excess cost in energy consumption as well as eliminating mechanical strain on system and drive components when starting them at full power.

This product is a limited function device with great capabilities. Its main purpose is to control the starting and stopping of a system or motor in both forward and reverse directions It also includes comprehensive monitoring of the three phases that are present and protective features to keep your operations running smoothly on top of protecting your investments. It additionally allows the individual programming of your operation.

AS interface is a field bus that allows local control of an actuator and local acceptance of sensor inputs at the starter.

A Profibus-DP integration is only available upon request and allows a communication interface for remote monitoring and control. 2 additional digital inputs are available with the AS interface models for easier integration into your application.

AS Interface Connectionwith M12 Plug Connectors

7

Modern automation systems have a wide range of requirements. Not all of these requirements include the need for speed control. The SK135E offers increased motor protection for simple local control.

For network control the SK175E may be used with built-in AS Interface or the optional Profibus version. This allows a soft starter to be integrated into as a communication network for monitoring and control. The SK135E family of soft start products is a great addition to the NORD line of electronic products.

The supply voltage (power) is via the appropriate terminals according to the rating (3~230/460V). For the control unit of the SK175E and the AS interface, the supply is via the (yellow) AS interface cable. This eliminates the need for an additional AUX cable (black).

Versions with AS-i on board: AS interface on board

SK 175E Only

To connect the AS-i cable and any initiators, appropriate M12 plug connectors can be provided ex-works. These are color-coded in order to provide a definite assignment of functionalities in the field. The following versions can be selected as options.

NORD CON

NORD CONNORD CON is the free operating software for controlling, programming and diagnosis of all NORD electronic products.

SK 135E/175E Interface ConnectionConnecting a SK135E or SK 175E to a PC/laptop is the most effective way to control your soft starter. Connection is accomplished via the RS232 diagnostic interface on top of the soft start device. The cable does not come standard with the unit but is available. We can provide a 10 foot sub D to RJ12 connector cable but needs to be ordered seperately. (Part Number 278 910 240)

ControlThe AC vector drive can be manually operated by means of a software window with all of the operating elements of a Controlbox. An enable signal can be given. The parameter settings can be adjusted and read. Parameters (information and error messages) can be viewed. Users therefore have a supporting aid for each commissioning.

ProgrammingWith a convenient overview, users can view and adjust each available parameter. By means of a print option complete parameter lists or lists of the changed values can be created. The finished data sets can be saved on the PC/laptop and archived for future use.

Diagnosis

The NORD CON oscilloscope function is a simple but very useful instrument for the optimal adjustment of a system. By means of line graphs, all characteristics (current, torque, etc.) can be recorded and analyzed. With these results, application-relevant settings can be fine-tuned to enable optimum operation. This is useful, e.g. for regulating the brake control or for lifting gear functions.

Direct-access to diagnostic tools

A great advantage of a distributed control system is that the location of the soft starter is near the motor, which is extremely beneficial in large plant facilities. Therefore direct access to the system for monitoring and diagnosis is a great benefit. The diagnostic tools for the SK 135E are easily visible and accessible behind a transparent screw-on cover.

Selectable Configurationof Drive Functions

Potentiometer SettingsAll potentiometers do not need to be configured, and each have 10 settings. P1 is for the rated motor current setting, P2 is for choosing a time for the reversal of a rotation set . Potentiometer P3 is used for setting the starting voltage for the start/torque set, and potentiometer P4 is the acceleration time set. The potentiometers are provided as standard with non-linear characteristics via software.

Configuring Your Drive Functions The SK 135E provides the possibility of setting the required drive functions from parameters by means of dip-switches.

Programming with dip-switchesThe direct access to dip-switches for setting the functions provides two advantages. If the storage module for the device is not available on site, the soft start device can also be operated with reduced functionality by means of the dip-switch setting.

Programming with the terminal stripThe drive can be operated from the terminal strip. You need to order or provide local operator controls. PLC outputs can supply operation command or field bus control. The control terminal block includes digital inputs, PTC inputs and digital outputs. Push in terminals are provided in order to eliminate the use of tools to attach wires to the block. The terminals are programmable and preprogrammed for the most common functions. If the terminal function definitions need to be adjusted, Nordcon, or an external control unit will be required.

Commissioning of the AS InterfaceOn SK 175E models that come standard with AS interface, connection of the AS interface cable is made via terminals of the terminal bar and can also optionally be made via an appropriately labelled M12 flanged plug contact (yellow).

The position of ASI connecting strip X4 and jumpers used for terminating the bus terminating resistor and are only available on the SK 175E models.

Optional Profibus SK 175E ModelOn the SK 175E models that are paired with Profibus, the bus terminating resistor is terminated with the use of jumpers. The bus terminating resistor must always be the first and last bus subscriber of the PROFIBUS DP.

The position of PROFIBUS connecting strip X4 and jumpers used for terminating the bus terminating resistor are only available on the SK 175E models.
