Chapter 1 - Introduction

General Description

The VMX2 Series is a digitally programmable solid-state reduced voltage soft starter. Its six SCR design features a voltage/current ramp with an anti-oscillation circuit for smooth load acceleration. The SCRs are sized to withstand starting currents of 500% for 20 seconds (Standard Duty) and up to 500% for 60 seconds (Heavy Duty). The VMX2 Series features smooth, stepless ramp control, which reduces motor inrush current and excessive wear on the mechanical drive train components. The VMX2 Series includes a programming keypad for setting operating parameters for the ideal starting cycle and protection features, plus easy to understand diagnostic LEDs.

Starting torque, ramp time, current limit, dual ramp, and Decel control are standard features on the VMX2 Series. By simply adjusting the units’ starting torque, ramp time, and current limit functions, the starting electrical characteristics of the motor can be matched to the mechanical characteristics of the drive train for controlled acceleration of the load. The VMX2 Series includes solid-state electronic overload protection in addition to numerous other protective features. It requires 120VAC (220VAC optional) control power and uses dry contact inputs for Start / Stop control. Programmable auxiliary contacts and provisions for interlocking are also included.

Sizes and ratings

The Motortronics VMX2 Series starters are current rated controllers. Max. Amp ratings are for continuous duty and must not be exceeded. Always check the motor nameplate FLA and Service Factor (if used) to ensure proper sizing. Each size has an adjustable range of current from 50% to 100% of the Max Amp rating. Table 1 to the left shows the Current Ratings available.

Chapter 2 – Installation

Receiving and Unpacking

Upon receipt of the product, you should immediately do the following:

 Carefully unpack the unit from the shipping carton and inspect it for shipping damage. If damaged, notify

the freight carrier and file a claim within 15 days of receipt.

 Verify that the model number on the unit matches your purchase order.  Confirm that the ratings nameplate on the unit match or are greater than the motors’ HP and current rating

with which it is to be used.

Choosing a Location Proper location of the VMX2 Series is necessary to achieve specified performance and normal operation lifetime. The VMX2 Series should always be installed in an area where the following conditions exist: Ambient operating temperature:

Panel (open chassis) unit: 0 to 50°C (32 to 122°F)

  Enclosed unit: 0 to 40°C (32 to 104°F)  Protected from rain, moisture and dust.  Enclosed units should not be exposed to direct sun.  Humidity: 5 to 95% non-condensing  Free from metallic particles, conductive dust and corrosive gas  Free from excessive vibration (below 0.5G)

Open panel units must be mounted in the appropriate type of enclosure. Enclosure size and type must be suitable to dissipate heat generated by the soft starter and any other components mounted inside with it.

Units with –BP Bypass Contactors produce less heat than units without. Throughout all sizes, maximum heat dissipation of the VMX2…-BP Series electronics, contactor coils and fans is less than 50W.

NOTE: This does not include heat generated by cables, lugs or busbars. Initial Unit Inspection

Make a complete visual check of the unit for damage that may have occurred during shipping and handling. Do not attempt to continue installation or start up the unit if it is damaged. Check for loose mechanical assemblies or broken wires which may have occurred during transportation or handling. Loose electrical connections will increase resistance and cause the unit to function improperly.

Mounting and Cleaning When drilling or punching holes in the enclosure, cover the electrical assembly to prevent metal filings from becoming lodged in areas which can cause clearance reduction or actual electrical shorts. After work is complete, thoroughly clean, vacuum the area, and re-inspect the unit for foreign material.

SERVICE WARNING! Do not service equipment with voltage applied! The unit can source of fatal electrical shocks! To avoid shock hazard, disconnect main power and control power before working on the unit. Warning labels must be attached to terminals, enclosure and control panel to meet local codes. Use Lock Out tags such as the one shown when servicing equipment.

Clearances

Make sure there is sufficient clearance all around the unit for cooling, wiring, and maintenance purposes. To conserve panel space, the VMX2 Series - BP models were designed for close clearances of only 1 inch (25mm) on either side. A minimum clearance of 4 inches (100 mm) on the top and bottom is necessary to maximize effective airflow and cooling. Also the unit must be installed with its heat sink ribs oriented vertically and running parallel to the mounting surface. Keep in mind that these are minimums. NEC or local codes may require more clearance, particularly for the power terminals.

Figure 2: VMX2 minimum mounting clearances

Cleaning:

In dirty or contaminated atmospheres, the unit should be cleaned on a regular basis to ensure proper cooling. Do not use any chemicals to clean the unit. To remove surface dust use clean, dry compressed air only, 80 to 100 psi. A three inch, high quality, dry paintbrush is helpful to loosen up the dust prior to using compressed air on the unit. Do not use wire brushes or other conductive cleaning materials.

WARNING! Remove all sources of power before cleaning the unit.

Electrical Connections

Power Connections

Referring to local code standards for wire sizing and length, connect power conductors to the unit input terminals marked L1, L2, L3 (R, S, T for IEC users). Connection points are bus tabs with pre-drilled holes (see section 2 of the Advanced Installation, Operation and Programming Manual). Use appropriate compression or mechanical lugs for termination to these bus tabs. Avoid routing power wires over the control board or display. Connect the motor leads to the unit terminals marked T1, T2, T3 (U, V, W for IEC users). If control power is present, but line power is disconnected from L1, L2, L3, the display will show [n3PH] indicating “no 3 Phase”.

Caution!

Never interchange input and output connections to the unit. This could cause excessive voltage in the control logic circuit and may damage the unit.

Bypass Contactor

Bypass Contactors are integral (built-in) on all VMX2 versions. See sections 1.2.3, 3.1.3.c and Appendix 4 of the Advanced Installation, Operation and Programming Manual for more details on contactor control and overload protection details.

Power Factor Correction Capacitors

Power factor correction capacitors can be connected to motors controlled by VMX2 Series starters, however they must be off-line during ramping. Connect PFC capacitors to the Line side of the starter with a separate capacitor control contactor.

WARNING! Never connect power factor correction capacitors on the load

side of the unit. The SCRs will be seriously damaged if capacitors are located on the load side.

Grounding

Connect the ground cable to the ground terminal as labeled on the unit. Refer to the National Electrical Code or your local Code for the proper ground wire sizing and be sure that the ground connector is connected to earth ground. In ungrounded systems, it is not necessary to connect a ground to the unit however local codes should always be consulted.

Control Connections

Control connections on the VMX2 Series starter are divided into 2 groups. With the unit oriented vertically, TB1 is a 12-point DC terminal block (on the left), and TB2 is a 10-point AC terminal block (on the right side). These are removable terminal blocks for ease of connection and servicing, and are provided with different spacing (pitch) between the header pins, so they are not interchangeable. Following are descriptions of control connection points.

 Note:

Terminal numbers are shown on the side of the first and last terminal of each block. An additional 3 point terminal on the far left side is for serial communication connections (see section

5.6.10 of the user manual).

AC Control Power Supply Connection

Separate AC Control Power supply is required to power the electronics of the VMX2 Series starter. The standard is 120VAC, but 240VAC (optional) can be ordered if necessary for your line power supply configuration. The control voltage must be connected to terminals marked A1 and A2 of TB-2 as shown in figure 4.2.1 (these

are also Terminal No.’s 21 and 22). This control voltage must be

customer supplied, unless an optional control power transformer (see table below) has been supplied with the unit.

Control Power Requirements When sizing a control power transformer for the VMX2…-BP Series

starter use the above chart for minimum sizes or supply capacity. Any additional control devices powered by the same CPT must be added to the above values to ensure proper operation of the Bypass Contactor.

Control Fusing The output relay contacts (TB2) must be protected from currents in excess of 5A by either using fuses or other suitable current protection devices.

A dedicated fault output for use in PLC or interposing relay control is available on TB1. This opto-isolated Triac switch is rated for 50mA max., 10-250V AC. Any circuit connected to it must be fused accordingly.

VMX2 Quick Setup Guide 12 | P a g e

Page 13

Basic Installation and Operation Guide

VMX2 Series Digital Solid State Soft Starters 18 – 1250A

Three-Wire Control Connection

For standard 3-wire control, connect dry (voltage free) contacts for the Stop / Start buttons as shown on the diagram directly above the terminal strip. Connect the N.O. contact of the Start button to Terminal 1 (far left terminal), the common point between the Stop and Start to Terminal 2 (2nd from left) and the N.C. from the Stop button to Terminal 3 (3rd from left).

 Seal In Contact The VMX2 Series uses an internally pre-wired “seal-in” contact around the Start button (Terminals 1 and 2). No external relay or auxiliary output connection is necessary.

Two Wire Control: Relay / PLC Connection

An alternate connection for automated or unattended operation replaces the start/stop push buttons by connecting a dry (voltage free) maintained contact closure between terminals 1 and 3 as shown in Figure 4.2.3. When this contact is closed, the VMX2 Series starter will start and run. When it is opened, it is the same as a Stop command.

 Automatic Functions and 2-Wire Control

When using the Auto Reset functions (F052 - F053), special consideration must be given to using 2-wire control. Refer to section 5.6.8 for details on using Auto-Reset functions.

 Note:

When a maintained contact is used for start/stop, it is advisable to set the overload relay to the manual reset position. This will prevent the motor from restarting if the thermal overload trips and then cools down.

CAUTION! Control Terminals 1-10 of TB1 are configured using solid state

devices powered internally with a 24VDC power supply. To prevent damage to the VMX2 Series control board, use dry (unpowered) contact closures only when connecting to these terminals.

If existing 120VAC or other powered control circuit must be interfaced, use isolating relays.

Interlock Connection

TB1 provides a connection point for an external dry (voltage free) N.C. (Normally Closed) interlock device between terminals 4 and 5. Examples where this interlock connection would be used include low oil, high temperature, or excess vibration dropout from user supplied devices. A factory-installed jumper is provided which allows the VMX2 Series unit to operate if external interlocks are not used. If this jumper is removed and an interlock is not used, the VMX2 Series unit will not function.

VMX2 Series Digital Solid State Soft Starters 18 – 1250A

Note: Ramp 2 terminals are defaulted

as “External Reset”, see parameter F113 for other options.

Note: Jog terminals are defaulted as “External Lockout, Normally Closed”, see parameter F113 for other options.

Enabling the Dual Ramp and Jog Features

TB1 includes provisions for enabling the Dual Ramp and Jog functions by using external contact closures. Both features use a common +24VDC from Terminal 7. However, they can be used independently of each other or together. See sections 5.6.2 and 5.6.3 of the user manual for full function descriptions and setup.

Dual Ramp Command Closing a dry (voltage free) contact between TB1, terminals 6 and 7 will enable Ramp 2, and the VMX2 Series starter will respond to the settings for Ramp 2 in F015 - F018. If no contact closure is present, the VMX2 Series starter defaults to the Ramp 1 parameters (F011 - F014). See Section 5.6.2.a of the user manual for setup of the Dual Ramp Feature.

The Dual Ramp feature is useful in instances where the load changes significantly. Example: a loaded or unloaded conveyor belt. The characteristics for starting an unloaded conveyor can be programmed for Ramp 1. The characteristics for starting a loaded conveyor can be programmed for Ramp 2. Ramp 2 can also be programmed for Full Voltage / Across-the-Line starting by setting the ramp time to 0 and Current to 600%.

Dual Ramp is also useful in 2-speed motor applications. Simply use an auxiliary contact from one of the speed contactors to select Ramp 2 so that separate ramp profiles can be used.

Dual Ramp input can also be configured as a “Remote reset”

(See parameter F113 and associated table)

 Jog / Remote Command

Connecting a dry (voltage free) contact between TB1, Terminals 7 and 8 will enable the Jog feature. A Start command (Run Command or Start button) is required to activate the Jog feature. See Section

5.6.3 for setup of the Jog Function. The Jog feature can be used for tasks such as lining up machines for

blade or bit changes, or inching belts along to check tracking. This input is also used to change the function of the Serial

Communications port control through F068. For additional information, see instructions of that function in section 5.6.11 of the user manual.

Jog input can be also configured as:

 “Remote” (via comm. link) / “Local” (T-strip), Start stop control.  “External Lockout” (N.O.)  “External Lockout” (N.C.)

(See parameter F113 and associated table)

 Using Both Commands

It may be useful to initialize the Ramp 2 and Jog command simultaneously when jogging. If this is the case, terminals 6 and 8 can be jumped together and controlled with one contact closure to Terminal 7 (the common 24VDC).

Analog Output (4-20mA)

The VMX2 Series starter provides a 4 to 20 milliamp output signal that can be set to monitor different parameter values using F108 and scaled with parameter F109 and F110. See section 5.6.16.

 External Overload Relay Connection

If an external Overload Relay (OLR) is used (see Section 3.1.3.c and Appendix 4), connect the N.C. aux. contact of the OLR across the Jog input (TB1 terminals 7&8), and re-program the

Jog input for “External Lockout N/C”, by changing F113 per table

in sect 5.6.17.

When the external OLR trips, the contact will open. This indicates an immediate Overload to the starter, which trips and displays [LcA, Lcc, or Lcd] depending on operation mode when the overload trips. If multiple OLRs are used, i.e. multiple motors controlled by the same VMX2 Series starter, simply wire the Aux Contacts in series as shown in Figure 4.2.6.a. See Appendix 4 for additional information.

 Note:

This feature is especially useful when using Deceleration Control because it will immediately shut off power to the motor even if Deceleration is active. If used this way, the trip indication will be [LcA, Lcc, or Lcd] depending on the operation mode when the trip is issued.

Fault Signal

An optically isolated Triac output is dedicated as a fault indicator on

TB1, terminals 11 and 12, labeled “Opto”. The output Triac switch is

rated for 10 - 250VAC, 50 mA (maximum). If the three programmable Output Auxiliary Relays are being used for other functions, this output can easily be hooked up to a PLC or small external relay to provide a Fault signal. This Fault Output operation is permanently fixed at “Any Trip”, duplicating the relay setting 22 as shown in Table 5.6.9. of the user manual.

This output is permanently set to this function and is not programmable.

Output (Auxiliary) Relay Contacts

Three programmable auxiliary relays are on TB2. The VMX2 Series starter comes with three programmable dry relay output contacts. Outputs 1 and 2 are Form C (SPDT), with a Common, N.O. and N.C. Output 3 is a Form A, (SPST), N.O. contact. It is not necessary to use the programmable output auxiliary relays in the Start / Stop circuit. An internal seal-in relay is provided elsewhere (see 4.2.2.a). Motortronics recommends fusing all outputs with external fuses.

The relays are rated for 240VAC, 5 A and 1200 VA. Factory default settings for these relays are as follows:  AUX 1 - Run / Stop (see F060).This contact changes state upon

a Start command, returns to normal on Stop (or Begin Decel if active).

 AUX 2 - At-Speed / Stop (see F061).This contact changes state

upon the VMX2 Series detecting At-Speed, and returns to normal on Stop. At-Speed is determined by the VMX2 Series detecting the current dropping after reaching End-of-Ramp, or a maximum of 30 seconds after Start.

 AUX 3 - Any Trip (see F062) This contact closes when any trip

condition 5 - 21 (as defined in Table 5.6.9 of the user manual) occurs.

All relays can be reprogrammed for a wide variety of functions. See Section 5.6.9 of the user manual for additional relay programming details.

Bypass Contactor Control

On VMX2…-BP version (and NEMA 12 enclosures) starters, an internal dedicated connection is used at the factory for automatically controlling the Bypass Contactor. Field wiring for Bypass Contactor operation is not required.

 Independent Bypass Contactor Control

The VMX2…-BP Series starters use standard industrial contactors that can be controlled independently of the starter electronics if necessary. When doing so, it is necessary to size the starter based upon the ATL (Across-the-Line) selection chart so that the contactors are rated for ATL duty instead of normal Shunt Duty. Supplemental overload protection will be required (see section 3.1.3.c of the user manual).

Units have external terminal blocks marked for this purpose (see Appendix 4 for drawings). A dry (voltage free) contact closure between these terminals will close the bypass contactor immediately. The Bypass Contactor coil voltage is the same as the control voltage (120VAC unless the optional 240VAC control is specified), and the voltage on these terminals is the same as the coil voltage.

No field wiring is necessary to these terminals if this feature is not used.

For all other styles of VMX2 Series, the At-Speed signaling can be programmed into any of the three Output relays (section 4.2.8 and Table 5.6.9 of the user manual).

Chapter 3 - Sequence of Operation

Starting:

1. Apply three phase power to the unit. The motor should not run until a Start command is applied.

2. Apply control power and check that the “Power On” LED comes on.

3. Status Display should read [0000.] showing no current in Phase A (minor flickering of the first digit is common).

4. Apply the Start (Run) command. The motor should begin to accelerate. Status display will read Phase A Amps at an increasing rate.

5. When the motor reaches full speed, the “At Speed” LED comes on and the Bypass Contactor will close. Status display should show a sharp decrease in Phase A Amps.

6. If the motor does not fully accelerate, decelerates, or stops during the acceleration period, hit the Stop button immediately and open the disconnect line.

Stopping:

If Pump-Flex Decel is Disabled (factory default) in F024:

1. Remove the Run Command (or hit the Stop button).

2. At-Speed LED will go out and Bypass Contactor will open. Status display should read [0000.] indicating no current on Phase A.

3. Motor will coast to a stop according to load inertia and friction.

If Pump-Flex Decel is Enabled in F024:

1. Remove the Run Command (or hit the Stop button).

2. At-Speed LED will go out and Bypass Contactor will open. Status display should briefly read Phase A Amps increasing as motor begins to decelerate.

3. Motor should begin to slow down. Status display should begin to show decreasing motor amps.

4. When motor reaches Stop Level, VMX2 should turn off. Status display will again show [0000.]

If the unit does not follow this operational sequence please contact the factory or refer to the VMX2 Series Troubleshooting Guide.

Chapter 4 – Programming

It is best to operate the motor at its full load starting conditions to achieve the proper time, torque and ramp settings. Initial factory settings are set to accommodate general motor applications and provide basic motor protection. Advanced features must be enabled via programming. The only parameter that MUST be set by the user is motor FLA (F001).

Digital Interface: The VMX2 Series Soft Starter includes a digital keypad with eight LEDs, seven command keys, and an LED display with four alphanumeric digits.

Display Modes There are three modes of display: The Status Display Mode, the Program Mode, and the Fault Mode. Status Display Mode (Default Display)

The Status Display Mode displays seven “screens” of information. Motor Currents (3 phases), Remaining Thermal Capacity, Ground Current, Remaining Time on the Process Timer, and Time Base of the Time Clock Controller. This is also the entry screen for going into the Program Mode. Status mode: [0000.] The initial display on power up is four digits and the decimal. This indicates the motor current for Phase A of the motor.

[0000] Scroll UP to display four digits only (no decimal). This indicates the motor current for Phase B. While viewing Phase B, press the UP arrow again to view Phase C current.

[G000] Scroll UP to display the “G”. This shows the value of the current flowing to ground on the motor leads. [H000] Scroll UP to display the “H”. This indicates the value of the remaining thermal capacity percentage of

the motor (i.e. H070 = 70% remaining thermal capacity)

Program Mode

The starter must be STOPPED in order to enter the Program Mode. Use the Program Mode to view or change Function (Fn) settings. To enter the Program Mode, press the [Fn] key once from the Status Screen described in section 5.3.1 of the Advanced Installation, Operation and Programming Manual. The first time you enter the Program Mode after power has been cycled to the starter, the initial function [F001] should be displayed with the selected digit flashing. If the VMX2 Series starter has been programmed and power to the unit has not been cycled, the readout will display the last function viewed or changed. To change to a different function, use the arrow keys.

Viewing Function Programming and Values

The programming of each individual Function can be viewed without making changes (values can also be viewed in the Run Mode however, no changes can be

made). Each Function is signified by the letter “F” in the

beginning of the data, the 4 digit value of the function follows after pushing the [READ/ENTER] key

• [F001] The “F” indicates the programmable Function.

• [0000] This is the present setting of the applicable

function.

This display may include decimals between digits depending on the function setting’s range and incremental

steps

[F001] The “F” indicates the programmable Function. [0000] This is the present setting of the applicable function. This display may include decimals between digits depending on the function setting’s range and incremental steps. Pressing the [Fn] key again will return to the Function display without making changes.

VMX2 Quick Setup Guide 21 | P a g e

Page 22

Basic Installation and Operation Guide

VMX2 Series Digital Solid State Soft Starters 18 – 1250A

Changing a Function’s Set Value

From the instructions above, after pressing the [READ/ENTER] key the display will show the value of that function with one digit flashing (usually the rightmost digit). Flashing indicates this is the digit to be altered (similar to cursor position). Use the UP arrow key to increment the value of the flashing digit. Use the DOWN arrow key to decrement the value of the flashing digit. Use the LEFT or RIGHT arrow to select the next digit to be altered. Values can only be changed within the Adjustment Range of the function parameter.

Pressing the [READ/ENTER] key again will store the new programming for that Function and return to the Function display.

If the display shows [Inh] when trying to store the changes, the unit is running and must be Stopped, or a Password has been set up to prevent access and must be entered first. See section 5.6.11 of the Advanced Installation, Operation and Programming Manual for details about this feature.

Caution! If the Fn key is pressed or power is lost before the [READ/ENTER] key is pressed, the

VMX2 Series Starter will not store the selected value in memory.

Fault Mode

The Fault Mode Display provides information to the operator when a fault occurs and allows the operator to review fault history. Refer to described in Section 7 of the Advanced Installation, Operation and Programming Manual for details. Fault codes are displayed by 3 alpha characters. The first and second characters (reading left to right) are the initials for the applicable English-language fault name. The third or right-most character

can be either A, c, or d to denote when the fault occurred. “A” denotes Acceleration. “c” denotes Constant

speed. “d” denotes Decel or Stopped.

Fault Mode

The VMX2 Series will automatically enter the Fault Mode when a fault occurs in the motor or starter and display a code indicating the condition that caused a shutdown. Fault codes are three-digits in length and are displayed in alpha characters. The first and second characters (reading left to right) are the initials for the applicable English-language fault name. The third or right-most character can be either A, c, or d to denote when the fault occurred. “A” denotes Acceleration. “c” denotes Constant speed. “d” denotes Decel or Stopped.

A Fault History of the past 3 events is stored and can be accessed by using the Up or Down Arrow keys before pressing the Reset button. The first (newest) event is indicated by the decimal point in the lower right corner. A more detailed history with time and date stamps is also kept in Functions 85 through 93.

Fault Codes: Basic common fault codes are shown in the chart below. For additional details refer to Chapter 7 of the

Advanced Installation, Operation and Programming Manual, or contact the factory for assistance.

Chapter 5 - Motor Overload Protection

Solid State Overload Protection

The VMX2 Series Starter provides true U.L. listed I2t Thermal Overload Protection as a built-in function of the main digital processor for maximum motor protection. It simulates the tripping action of a bi-metallic overload relay, with the accuracy and repeatability of a digital control system. It is adjustable over a wide range and can be easily programmed for different trip curves.

Thermal Memory

The VMX2 Series microprocessor uses a sophisticated “Thermal Register” in the digital memory to keep track of motor heating and cooling over time regardless of the starter’s power status. By using nonvolatile memory, the VMX2 Series does not “forget” that the motor has been running even if power to the starter is turned off and back on. Continuous overload protection is provided based on the true thermal condition of the motor.

Thermal Capacity The Thermal Register is displayed as a percentage. This percentage is the motor’s remaining thermal

capacity. The percentage value begins at 100, showing that the motor is cool (has 100% of its capacity available). As the motor heats up or moves toward an overload condition, the percentage begins to drop. The Thermal Capacity is derived from the programmed motor nameplate Full Load Amps (FLA) in Function F001, the Service Factor rating in Function F002, and the Overload Trip Class in Functions F003 and F004. Setting these functions to the proper values provides maximum protection and eliminates nuisance tripping.

Examples: The Remaining Thermal Capacity can be viewed by using the UP or DOWN arrow

keys when in the Status Display mode. From the default Phase A Current screen (dot on right side), press the UP arrow key 4 times to display [H100] meaning there is 100% of the Thermal Capacity (H = Heat capacity) remaining in the motor. After starting or running, the motor will use this capacity and the display will show a lower number. For example, after a cold start, the display may read [H065] which indicates that the motor has 65% of its thermal capacity remaining (35% used). The Status Display screens cycle back to the beginning, so the Down arrow keys can get to this display as well.

Motor Full Load (FLA) Setting

Use Function F001 to enter motor FLA as indicated on the motor nameplate. (Do not

calculate for service factor, this is programmed separately in F002).

Note: All VMX2 Series starters are shipped from the factory with F001 set to a default value of 0000. If F001 is left at the factory default, the unit will not operate. If the user attempts to start the VMX2 Series without entering the motor nameplate FLA,

Disabling the Overload Protection

The Overload Protection feature can be disabled if necessary. Please refer to the Advanced Installation, Operation and Programming Manual for instructions and considerations before disabling the Overload Protection

the starter will Fault and the display will read “nFLA” (no Full Load Amps).

WARNING! Do NOT disable Overload Protection unless another Thermal Overload

Protection device exists in the circuit for all three phases. Running a motor without Overload Protection presents serious risk of motor damage or fire.

Basic Installation and Operation Guide

VMX2 Series Digital Solid State Soft Starters 18 – 1250A

Manual Reset The factory default setting is Manual Reset. This means that when the Overload Trip is activated, the starter cannot be restarted without pressing the Reset key. The Overload Trip will not reset until the motor cools down (see 3.1.3.d of the user manual). The Manual Reset function is also “trip free”. Holding in the Reset key will not prevent the Overload Trip from activating and protecting the motor.

Note: When the Overload Trip activates, the Overload LED will glow solid. When the motor cools down, the LED will begin to flash, indicating that the Overload Trip can be reset.

Automatic Reset If Automatic Reset is necessary, change from Manual Reset to Automatic Reset by using Function F005. (See Section 5. of the Advanced Installation, Operation and Programming Manual for details). In this mode, a 3-wire control circuit will be capable of restart when the VMX2 Series has reset itself after the cool down period.

WARNING!

Two-wire control systems may restart without warning when Auto Reset is selected. Extreme caution should be exercised. To prevent automatic restarting with 2-wire control systems, use external interlocking to provide sufficient warning and safety to operators. A Warning Label similar to that shown below (and the one provided in the packet with this manual) must be located where visible (on the starter enclosure and/or the driven equipment) as required by local code.

WARNING: MOTOR CONNECTED TO THIS EQUIPMENT MAY START AUTOMATICALLY WITHOUT WARNING

NEMA Class Trip Curves

NEMA Class trip curves are based on a common tripping point of 600% of motor Full Load Amps (FLA). Curves vary by the amount of time before the unit trips. As an example, a Class 20 curve will trip in 20 seconds at 600% of FLA. The factory default setting of Class 10 will trip in 10 seconds at 600% of FLA.

Dual Overload Trip Curves The VMX2 Series Soft Starter provides two separate Overload Trip Protection Curves, one for starting and

one for running conditions. The starter’s At -Speed detection circuit determines when the motor has reached full speed. When the At-Speed condition is reached, the overload trip curve will shift from the Start to the Run level, as programmed in Functions F003 and F004. See Section 5.6.1 of the Advanced Installation, Operation and Programming Manual for programming details.

Starting Overload Trip Curve During the start mode, Overload Trip Curves are selectable from NEMA Class 5 through Class 30 only.

The default setting of Class 10 allows protection for the overload capacity of the soft starter as well as the motor. Use a higher Trip Class only if nuisance tripping occurs with the default setting.

Running Overload Curve During the Run mode, Overload trip curves are selectable from NEMA Class 5, 10, 15, 20, 25, and 30.

Program the appropriate curve according to the characteristics of your motor and load.

Overload Trip Curve Chart

Figure 9: VMX2 Series Overload Trip Curves Overload Protection During Bypass

When a Bypass Contactor is used to shunt power around the SCRs in the VMX2 Series (as in the VMX2…-BP version), overload protection is maintained as long as the VMX2 Series is directly controlling the contactor. No additional Overload Relay is necessary for normal operation.

Special Consideration for Across-the-Line (Direct-on-Line) Contactors When the Bypass Contactor on a VMX2…-BP Series has been selected to be used for Across-the-Line

restart, supplemental overload protection must be added. For this application, refer to the External Overload Relay Applications supplement and wiring diagram in Appendix 5 and section 4.2.6.a of the Advanced Installation, Operation and Programming Manual for detailed instructions.
