The examples and diagrams in this manual are included solely for illustrative purposes. The information contained in this manual is subject to change at any time and without prior notice. Responsibility or liability is never accepted for direct, indirect, or consequential damage resulting from the use or application of this equipment.

1.2 Warnings

WARN IN G

UNEXPECTED BEHAVIOR

When the soft starter is connected to mains voltage, the Pumping Smart Card can start or stop the motor without warning. Unexpected behavior can lead to personal injury.

To ensure personnel safety, isolate the soft starter from mains voltage before installing the smart card.

WA RN IN G

RISK OF PERSONAL INJURY AND EQUIPMENT DAMAGE

Inserting foreign objects or touching the inside of the soft starter while the expansion port cover is open may endanger personnel and can damage the soft starter.

Do not insert foreign objects in the soft starter with the port cover open.

Do not touch the inside of the soft starter with the port cover open.

NO TI CE

The hydraulic characteristics of pump systems vary considerably. The default parameter settings may not be suitable for every application and care should be taken to configure the soft starter appropriately.

Overview

2 Overview

2.1 Features of the Pumping Smart Card

The Pumping Smart Card provides dedicated inputs for pressure, depth, temperature, and flow sensors to allow protection, control, and monitoring integration in a range of pumping applications.

2.1.1 Monitoring

Data from analog or pulse sensors can be shown directly on the display of the soft starter.

A real-time graph is also available if the optional remote LCP is installed.

2.1.2 Protection

The smart card can trip the soft starter based on user-selected levels for high or low pressure, depth, temperature, or flow.

2.1.3 Control

The smart card can automatically start and stop the soft starter in response to rising or falling pressure, or rising or falling depth.

Smart card control can be used with the VLT® Soft Starter MCD 600 scheduling function to restrict starting or stopping to specified days and times.

4.1 Installing the Expansion Card

Procedure

1. Push a small flat-bladed screwdriver into the slot in the center of the expansion port cover and ease the cover away from the soft

starter.

2. Line up the card with the expansion port.

3. Gently push the card along the guide rails until it clicks into the soft starter.

Example:

Illustration 1: Installation of the Expansion Cards

4.2 Compatible Input Devices

The smart card supports the following types of input devices:

• Analog 4–20 mA active (self-powered) and passive (loop-powered)

• Pulse

• Digital switch

4.3 Active and Passive 4–20 mA Input Devices

The wiring connections for 4–20 mA sensors vary depending on how the sensor is powered. This manual describes the wiring connections for passive (loop-powered) sensors, but active (self-powered) sensors can also be used by changing the wiring connections.

• Passive (loop-powered) sensors are powered from the 4–20 mA terminals of the smart card. For these sensors, use B13-B14, B23B24, B33-B34.

• Active (self-powered) sensors have either an internal or external power supply. The sensor is not powered from the smart card terminals. For these sensors, connect the 0 V to terminal R1 and connect the active input to B13, B23, or B33 as required.

NO TI CE

Smart card protection features are always active while the soft starter is operating. Smart card protection is not affected by the command source.

NO TI CE

To use the smart card to control the soft starter, use sensors connected to B23, B24.

NO TI CE

6.1 Parameter Configuration

Operating parameters for the Pumping Smart Card are set and stored in the soft starter. Parameters can be configured via the main menu or uploaded using the USB Save & Load function.

For details on how to configure the soft starter, see the VLT® Soft Starter MCD 600 Operating Guide.

In the parameter descriptions, an asterisk (*) indicates the default setting.

6.2 Off-line Configuration

NO TI CE

Parameters for smart card functions are only visible in the parameter list if the smart card is installed.

To configure smart card settings in the soft starter before the card is installed, generate a parameter file in the MCD PC Software and load it into the soft starter using USB Save & Load.

6.3 Flow Protection

Flow protection uses terminals B33, B34 or C23, C24 on the smart card.

• B33, B34: Use an analog 4–20 mA sensor.

• C23, C24: Use a normally open digital switch sensor for protection only, or use a pulse sensor for protection and monitoring.

Flow protection is active when the soft starter is in start, stop, or run mode.

The smart card trips the soft starter when the flow rate passes through the programmed trip level. If the flow rate is still outside the expected operating range when the trip is reset (including auto-reset), the soft starter does not trip again.

6.5.1 Configuring Pressure Control

Procedure

1. Connect the sensor to B23, B24.

2. Set parameter 30-1 Pressure Sensor Type to Analog.

3. Set parameters 30-2 to 30-4 according to the sensor specifications.

4. Set parameters 33-1 to 33-5 as required.

5. Set parameter 1-1 Command Source to Smart Card or Smart Card+Clock.

6.5.2 Operation

There are 2 different operating modes when using pressure control:

6.6 Depth Protection

Depth protection uses terminals B13, B14 or C13, C14 on the smart card.

• B13, B14: Use an analog 4–20 mA sensor.

• C13, C14: Use a normally open digital switch sensor.

Depth protection is always active (ready, start, run, and stop modes).

The smart card trips the soft starter when the depth level passes through the programmed trip level. The trip cannot be reset until the depth has returned above the reset level (parameter 34-2 Depth Reset Level).
