SMC-Flex™Getting Started

Introduction This guide provides you with the basic information required to start up your SMC-Flex™ controller. Factory default settings and information regarding installing, and programming, the controller are described here.

This guide is intended for qualified service personnel responsible for setting up and servicing these devices. You must have previous experience with and a basic understanding of electrical terminology, configuration procedures, required equipment, and safety precautions.

Installation The open-style design of the SMC-Flex controller requires that it be installed in an enclosure. The internal temperature of the enclosure must be kept within -5…50°C (23…122°F).

The controller is fan cooled. It is important to mount the controller in a position that allows air to flow vertically through the power structure. Allow for a minimum of six inches (15 cm) of free space around all sides of the controller.

Wiring Power Wiring

Refer to the product nameplate for power lug termination information including:

• Lug wire capacity

• Tightening torque requirements

• Lug kit catalog numbers (108…480 A)

Control Wiring

Refer to the product nameplate for control terminal wire capacity and tightening torque requirements. Each control terminal will accept a maximum of two wires.

The SMC-Flex controller accepts control power input of 100…240V AC or 24V AC/DC, (+10/–15%) single-phase, 50/60 Hz. Refer to the product nameplate prior to applying control power. Connect control power to the controller at terminals 11 and 12. For controllers rated 1…480 A (1.7…831 Delta), control power of 125 VA is also required. The control power requirement for the control module is 75 VA. The control power requirement for the fans is 20 or 50 VA. Depending on the specific application, additional control circuit transformer VA capacity may be required.

➊ Do not connect any additional loads to these terminals. These “parasitic” loads may cause problems with operation, which may result in false starting and stopping.

➋ External Bypass operates an external contactor and overload once the meter reaches full speed. The SMC-Flex overload functionality is disabled when the external bypass is activated. Proper sizing of the contactor and overload is required.

➌ RC Snubbers are required on loads connected to auxiliary.

Factory Default Settings

The SMC-Flex controller is pre-programmed with the settings listed in the table below.

Saving Programmed Values to Memory

After you have programmed the controller settings you must save them to the controller’s memory. To do this, follow the steps below:

1. Scroll to Parameter Mgmt. This is the last parameter provided in the Setup, Motor Protection, Communication, Utility, and Linear List.

2. Select the User Store option.

3. Press Enter.

ATTENTION

!Overload protection in the SMC-Flex controller is disabled from the factory. The user must program the desired overload trip class, motor full load current rating, and Service Factor to achieve proper protection.

IMPORTANT If control power is removed from the SMC-Flex controller before you store the programmed values to memory, all programmed values will be lost.



Basic Setup To properly setup the SMC-Flex, go to the Basic Setup list and set parameters to meet the application needs. Motor FLA and Service Factor must also be setup for proper operation. No additional calibration procedures are necessary for proper operation of the SMC-Flex.

Communication A serial interface port for DPI (Drives Peripheral Interface) communication modules is provided as standard. DeviceNet, ControlNet, EtherNet, RS-485, RIO, ProfiBUS, and InterBUS communication modules are also available (Bulletin 20-COMM).

A serial interface port called DPI is provided as standard, and allows connection to a Bulletin 20-HIM-C3 human interface module.

Figure 6: SMC-Flex DPI Location

ATTENTION

!Two peripheral HIM devices can be connected to the SMC-Flex. The maximum output current through the SMC-Flex is 280 mA.

The SMC-Flex allows HIM interface and DPI communication.



Human Interface Modules The Bulletin 20-HIM-C3 human interface modules with control panels can start and stop the SMC-Flex controller. However, the factory default settings disable control commands other than Stop through the serial communication port.

Figure 7: Human Interface Module

To enable motor control from a connected human interface module or communication module, you must take the following programming steps:

Series A

1. Disconnect the HIM and allow to power down.

2. Reconnect the HIM. On Initializing screen, the bottom right corner of LCD shows Port X. Note this port number.

Port 5 — DPI Communications

Port 2

Ports 2 and 3 when two HIMs are connected with a splitter



3. Go to Logic Mask, found as follows: Main Menu: Parameter/Communications/Comm Mask/Logic Mask

4. Set b0X equal to 1 (where X is the port number noted in step 2).

5. Go to Parameter Management and save as User Store.

IMPORTANT The Logic Mask must be set to 0 prior to disconnecting a human interface module from the SMC-Flex controller. If not, the unit will fault on a “Coms Loss”.
