1.1 General Description
The TE2 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 TE2 Series features smooth, stepless ramp control, which reduces motor inrush current and excessive wear on the mechanical drive train components. The TE2 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 TE2 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 TE2 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.

1.2 Sizes and Ratings
The Toshiba TE2 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 to ensure proper sizing.
Each size has an adjustable current range of 50% to 100% of the Max Amp rating. Table 1.2 shows the Current Ratings available.
1.2.1 Selecting for Service Factor Utilization Many NEMA design motors include a design rating referred to as Service Factor (SF) that may allow continuous operation above the nameplate current rating. If using this Service Factor, the TE2 Series starter must be sized for the total amps used. For proper selection of the TE2 Series starter when using SF continuously, multiply the nameplate FLA by the stated Service Factor, or use stated Service Factor Amps (SFA) if listed on the nameplate. The following excerpt is from the NEMA MG-1 standards for AC Motors that describes the issues concerning the use of Service Factor ratings.
"When an induction motor is operated at any service factor
greater than 1.0, it may have efficiency, power factor and speed different than those at rated load. Locked rotor torque and current and breakdown torque will remain the same. A motor operating continuously at any service factor greater than
1.0 will have a reduced life expectancy compared to operating at its nameplate horsepower."
When using this feature, simply program the TE2 Series Service Factor (F002) to the nameplate rating. (See section
5.6.1.) All other adjustments to the protection circuits are done automatically within the TE2 Series.
1.2.2 Selecting for Across the Line Bypass If you need to be able to start the motor Across-the-Line when the TE2 Series electronics are out of service, the starter can also be selected based upon the rating of the Bypass Contactor. Some users may also elect to size their Bypass Contactors per NEMA guidelines. When doing this, please refer to the Product Selection Guide for details and notes, and see Appendix 4 for special considerations regarding Overload Protection.
1.2.3 The TE2…-BP Series starters include the ability to connect a dry contact directly to the Bypass Contactor coil control circuit. These terminals are covered when shipped and should be used ONLY when necessary for Emergency Bypass operation and with an external Overload Relay. See Appendix 4 for additional information.
No field wiring to these terminals is necessary if this feature is not used.

Chapter 2 - Installation
2.1 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.
2.2 Choosing a Location
Proper location of the TE2 Series is necessary to achieve specified performance and normal operational lifetime. The TE2 Series should always be installed in an area where the following conditions exist:
Ambient operating temperature: 0 to 40°C (32 to 104°F)
Protected from rain, moisture, and 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.
Care should always be taken to maximize the available space
inside of the enclosure. See section 2.5.1 or contact factory for assistance in sizing enclosures.
2.3 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.
Prior to beginning the installation, verify that the motor and TE2
Series unit is rated for the proper amperage and voltage.
TE2 Series Digital Solid State Soft Starter User Manual 5 | Page
2.4 SERVICE WARNING!
r
Do not service equipment with voltage applied! The unit can be the 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 Lockout tags such as the one shown when servicing equipment.
2.5 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.
2.5.1 Clearances
Make sure there is sufficient clearance all around the unit for cooling, wiring, and maintenance purposes. To conserve panel space, the TE2 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.

WARNING! Remove all sources of power before cleaning the unit.
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
2.6 Power Terminations
All line and load power terminations are to be made to the tin plated copper Bus Tabs located on each unit. Bus tabs are pre-drilled to accept industry standard bolts. Toshiba recommends using crimp-on ring lugs, although mechanical compression lugs are suitable as well. The following diagrams show sizes of the bus tab holes and critical spacing between them for determining the size of lug that can be used.
Note: All wiring must be sized according to local and national code standards.

Chapter 3 - Motor Overload Protection
3.1 Solid State Overload Protection
MOTOR FLA (F001)
must be programmed
for unit to operate!
Examples:
H100
100% Thermal
Capacity remaining
at rest
H057
57% Thermal Capacity remaining after starter
(43% used)
The TE2 Series Starter provides true U.L. listed I Protection as a built-in function of the main digital processor for maximum motor protection. It mimics 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 is easily be programmed to different trip curves.
3.1.1 Thermal Memory
The TE2 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 TE2 Series does not “forget” that the motor has been running even if power to the starter is turned off and turned back on. Continuous overload protection is provided based on the true thermal condition of the motor.
3.1.2 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.
The Remaining Thermal Capacity is 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 access this display as well.
3.1.2.a 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 TE2 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 TE2 Series without entering the motor nameplate FLA, the starter will Fault and the display will read “nFLA” (no Full Load Amps).

Series Digital Solid State Soft Starter User Manual 11 | Page
3.1.3 Disabling the Overload Protection
The Overload Protection feature can be disabled if necessary. When using external devices such as Motor Protection Relays or when the TE2 Series is wired downstream from an existing starter, this feature can be disabled to prevent conflicts with external Overload Protection devices. When the TE2 Series is controlling multiple motors, the built-in Overload Protection must be disabled and individual thermal overload relays must be installed on the motor leads going to each motor (see Appendix 4 for additional details). To disable the Overload Protection function, use F005.
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.
3.1.3.a 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). 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 be on solid. When the motor cools down, the LED will begin to flash, indicating that the Overload Trip can be reset.
3.1.3.b Automatic Reset
If Automatic Reset is necessary, change from Manual Reset to Automatic Reset by using Function F005. (See Section 5 for details). In this mode, a 3-wire control circuit will be capable of restart when the TE2 Series has reset itself after the cool down period.
WARNING! Two-wire control systems may restart without warning when Auto
Reset of the Overload Protection 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: M OT OR CONNECT ED T O T HIS EQUIPM ENT
MAY ST ART AUT OMAT ICALLY WIT HOUT WARNING
TE2 Series Digital Solid State Soft Starter User Manual 12 | Page
3.1.3.c Overload Protection During Bypass
When an integral Bypass Contactor is used to shunt power around the SCRs in the TE2 Series (as in the TE2…-BP version), overload protection is maintained as long as the TE2 Series is directly controlling the contactor. No additional Overload Relay is
necessary for normal operation.
When the Bypass Contactor on a TE2…-BP Series has been
selected to be used for Across-the-Line restart (reference section
1.2.3), supplemental overload protection is necessary. For this application, refer to the External Overload Relay Applications supplement and wiring diagram in Appendix 4.
3.1.3.d Dynamic Reset Capacity
The TE2 Series includes the ability to dynamically track the Thermal Capacity needed for a successful restart after an overload trip. It averages the Thermal Capacity consumed in the previous three successful starts, and calculates a Thermal Capacity to Start (viewed in Function F059). After tripping on Overload, the Thermal Register must have regained the amount recorded in F059 before a Reset will be allowed. If the display reads [Inh] when attempting to reset an overload trip, it is indicating that the starter is Inhibited from being reset.
Refer to details of Function F071 for information on emergency override of lockouts such as this.
3.2 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.
3.2.1 Dual Overload Trip Curves
The TE2 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 for programming details.
3.2.2 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.
TE2 Series Digital Solid State Soft Starter User Manual 13 | Page
3.2.3 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.

4.1.2 Power Factor Correction Capacitors Power factor correction capacitors can be connected to motors
TE2 Power Connections
Figure 4.1:
4.1 Power Connections
Refer to national and local code for wire sizing and length, connect power conductors to the unit input terminals marked L1, L2, L3 (R, S, T for IEC users). 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.
4.1.1 Bypass Contactor
Bypass Contactors are integral (built-in) on all TE2 sizes. See sections
1.2.3, 3.1.3.c, and Appendix 4 for more details on contactor control and overload protection details.
controlled by TE2 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.
4.1.3 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 size, and be sure that the ground connector is connected to earth ground.
TE2
Series Digital Solid State Soft Starter User Manual 15 | Page
4.1.4 Testing The TE2 Series can be tested with a load smaller than the motor it was
originally selected to control, however additional steps must be taken to avoid tripping on Phase Current Loss. See section 5.6.8.a under “Phase Loss Protection” for additional details on performing this task.
Notes:
The unit cannot be tested without a motor or other test load connected to the load side of the unit. It may be necessary to use a load bank to test the unit without a motor.
Line voltage will appear across the output terminals if there is no
motor or load connected to the unit.
4.1.5 Lightning Protection
As with all electronic power controllers, protection from damage by lightning surges is recommended in areas where lightning is a significant problem. Stationary SPDs (Surge Protection Device) should be considered and utilized on the input power source. The best method of protection is to have an Isolation Contactor in front of the starter that is open when the soft starter is not in use. Enclosed versions may be provided with a surge protection device.
4.2 Control Connections
Control connections on the TE2 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).

4.2.1.a Control Power Requirements
When sizing a control power transformer for the TE2…-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.
4.2.1.b 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.
TE2 Series Digital Solid State Soft Starter User Manual 17 | Page
4.2.2 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
nd
(2
from left) and the N.C. from the Stop button to Terminal 3 (3rd from
left). 4.2.2.a Seal In Contact
The TE2 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.
4.2.3 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 TE2 Series starter will start and run. When it is opened, it is the same as a Stop command.
4.2.3.a 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 TE2 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.
4.2.4 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 TE2 Series unit to operate if external interlocks are not used. If this jumper is removed and an interlock is not used, the TE2 Series unit will not function.
TE2
Series Digital Solid State Soft Starter User Manual 18 | Page
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.
4.2.5 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 for full function descriptions and setup.
4.2.5.a Dual Ramp Command
Closing a dry (voltage free) contact between TB1, terminals 6 and 7 will enable Ramp 2, and the TE2 Series starter will respond to the settings for Ramp 2 in F015 - F018. If no contact closure is present, the TE2 Series starter defaults to the Ramp 1 parameters (F011 - F014). See Section 5.6.2.a 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)
4.2.5.b 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.
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)
4.2.5.c 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).
TE2 Series Digital Solid State Soft Starter User Manual 19 | Page
4.2.6 Analog Output (4-20mA)
The TE2 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 5.5.16.
4.2.6.a 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 TE2 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.

4.2.7 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.
This output is permanently set to this function and is not programmable.
4.2.8 Output (Auxiliary) Relay Contacts
Three programmable auxiliary relays are on TB2. The TE2 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). Toshiba 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 TE2 Series detecting At-Speed, and returns to normal on Stop. At-Speed is determined by the TE2 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) occurs.
All relays can be reprogrammed for a wide variety of functions. See Section 5.6.9 for additional relay programming details.
