TE Series Digital Solid State Soft Starters 18 – 1250A
Chapter 1 - Introduction
1.1 General Description
The TE 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 350% for 30 seconds and up to 600% for 10 seconds. The TE Series features smooth, stepless ramp control, which reduces motor inrush current and excessive wear on the mechanical drive train components. The TE Series includes a programmable 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 TE Series, as well as the integrated Batch Process Timer and Time Clock Controller used for automated applications. By simply adjusting the unit’s 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 TE Series includes solid-state electronic overload protection in addition to numerous other protective features. It requires 120VAC (240VAC optional) control power and uses dry contact inputs for Start / Stop control. Programmable auxiliary contacts and provisions for interlocking are also included.

"When an induction motor is operated at any service factor
When using this feature, simply program the TE Series
NOTE:
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 TE Series starter must be sized for the total amps used. For proper selection of the TE 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. Following is an excerpt from the NEMA MG-1 standards for AC Motors that describes the issues concerning the use of Service Factor ratings.
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."
Service Factor (F002) to the nameplate rating see section
5.6.1. All other adjustments to protection circuits are done automatically within the TE Series.
1.2.2 Selecting for Across the Line Bypass If you need to be able to start the motor Across-the-Line if the TE 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. Please use the Product Price Catalog
for details and notes on doing this, and see Appendix 5 for special considerations regarding Overload Protection.
The TE…-BP Series starters include the ability to connect a dry contact directly to the Bypass Contactor coil control circuit. These terminals shipped are covered and should be used ONLY when necessary for Emergency Bypass operation and
with an external
Overload Relay. See Appendix 5 for additional information. No field wiring is necessary to these terminals 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 sticker on the unit matches or is greater
than the motor’s HP and current rating.
2.2 Choosing a Location
Proper location of the TE Series is necessary to achieve specified performance and normal operation lifetime. The TE 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 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 TE…-BP Series electronics, contactor coils and fans is less than 50W.
Units without the –BP Bypass Contactor (optional on 210A and
above), must have ventilation adequate to account for heat dissipation of the SCRs. This must be estimated at 4.5 watts per running load amp. For example, on a 200HP 460V motor with 240FLA, the maximum heat dissipation of a starter w/o bypass will be 240 x 4.5, or 1080 watts of heat. Enclosure ventilation (or air conditioning) must be capable of dispersing this amount of heat.
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 TE
Series unit are rated for the proper amperage and voltage.

WARNING
2.4 SERVICE WARNING! 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 Lock Out 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 actually short out electronics. 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 TE Series –BP models were designed for close horizontal clearances of only 1 inch (25mm) on either side. A minimum vertical clearance of 4” (100 mm) on the top and bottom is necessary to maximize effective airflow and cooling, and 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. Wiring may require more clearance, particularly on the bottom.

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 tin plated copper Bus Tabs located on each unit. Bus tabs are pre-drilled to accept industry standard bolts. Some sizes come with saddle clamp terminals, however lugs are the responsibility of the user. Toshiba recommends using crimp-on lugs, although mechanical 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.

3.1 Solid State Overload Protection
The TE Series Starter provides true U.L. listed I Protection as a built-in function of the main digital processor for maximum motor protection. It simulates the tripping action of a bi­metallic 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.
3.1.1 Thermal Memory
The TE 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 non-volatile memory, the TE 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 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 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.
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 TE 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 TE Series without entering the motor nameplate FLA, the starter will Fault and the display will read “nFLA” (no Full Load Amps).

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 TE Series is wired downstream from an existing starter, this feature can be disabled to prevent conflicts with external overload protection devices. When the TE 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 5 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 glow 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 TE 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: MOTOR CONNECTED TO THIS EQUIPMENT
MAY START AUTOMATICALLY WITHOUT WARNING

TE Series Digital Solid State Soft Starters 18 – 1250A
3.1.3.c Overload Protection During Bypass
When an integral Bypass Contactor is used to shunt power around the SCRs in the TE Series (as in the TE…-BP version), overload protection is maintained as long as the TE Series is directly controlling the contactor. No additional Overload Relay is
necessary for normal operation.
CAUTION
If a Bypass Contactor is added by the user in the field (i.e. 210A units and above), care must be taken to ensure proper power routing to ensure functioning of the Overload protection. Consult factory for assistance.
When the Bypass Contactor on a TE…-BP Series has been
selected to be used for Across-the-Line restart (reference section
1.2.3), supplemental overload protection may be necessary. For this application, refer to the External Overload Relay Applications supplement and wiring diagram in Appendix 5 and section 4.2.6.a.
3.1.3.d Dynamic Reset Capacity
The TE 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 TE 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 20 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.
13
TE Series Digital Solid State Soft Starters 18 – 1250A
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.

*Larger units (210A and above) can be ordered with fan cooling instead of Bypass Contactors, but are intended for use in NEMA 1 ventilated enclosures only. Do not use the TE starter in a sealed enclosure without a bypass contactor.
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.
G
4.1.1 Bypass Contactor
Bypass Contactors are integral (built-in) on all TE…-BP (panel mount), and all TE…–E (NEMA 12 enclosed) versions. See sections 3.2.1.c and
4.2.5 for more details on contactor control and overload protection details.
4.1.2 Power Factor Correction Capacitors
Power factor correction capacitors can be connected to motors controlled by TE 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 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.
15
TE Series Digital Solid State Soft Starters 18 – 1250A
4.1.4 Testing The TE 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 5.6.9.a under “Phase Loss Protection” for additional details on performing this task.
NOTE:
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.
IMPORTANT NOTE:
Fault code SSd may display if there is no output load connection when control power is applied!
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 air gap lightning arrestors 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.
4.2 Control Connections
Control connections on the TE 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 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 5.6.11).

.2.1.a Control Power Requirements
When sizing a control power transformer for the TE…-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 figures to ensure proper operation of the Bypass Contactor.
NOTE:
TE-210 and larger units are available without the Bypass Contactor, but fans are still included. CPT can be sized for fan loads only if used in NEMA 1 ventilated enclosures.
4.2.1.b Control Fusing
Output relays in TB2 must be protected from currents in excess of 5A, either with a fuse or with 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/DC. Any circuit connected to it must be fused accordingly.

4.2.2 Three-Wire Control Connection
For standard 3-wire control, connect dry (voltage free) contacts of the
OPTO
Stop / Start buttons as shown on the diagram directly above the terminal strip. Connect the NO 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 NC from the Stop button to Terminal #3 (3rd from
left). 4.2.2.a Seal In Contact
The TE 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
OPTO
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 TE 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
If using the Time Clock functions (F032-F039) or Auto Reset functions (F052 – F053), special consideration must be given to using 2 wire control. Refer to Appendix 3 for additional details and information on time clock functions, and section 5.6.9 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 off.
CAUTION
Control Terminals 1-10 of TB1 are a 24VDC circuit from an internal power supply of the TE Series.
Use dry (unpowered) contact closures only. Applying any voltage to these terminals will result in damage to the TE Series control board.
If existing 120VAC or other powered control circuit must be interfaced, use interposing relays or control the TE Series wit h 2 wire control as shown above.
4.2.4 Interlock Connection
TB1 provides a connection point for an external dry (voltage free) N.C.
OPTO
(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 TE Series unit to operate if external interlocks are not used. If this jumper is removed and an interlock is not
used, the TE Series unit will not
function.

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 TE Series starter will respond to the settings for Ramp 2 in F015 - F018. If no contact closure is present, the TE 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.
4.2.5.b Jog / Remote Command
OPTO
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.
4.2.5.c Using Both Commands
OPTO
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).

The TE Series starter is provided with input terminals for connecting a
OPTO
PTC (Positive Temperature Coefficient) Thermistor that may be imbedded in the motor. These are specialized resistors imbedded in some motor windings that increase resistance as the temperature increases. When the TE Series detects that the PTC input resistance is too high, it initiates a PTC trip, and displays it on the readout as [ PTc ]. This is independent of the Thermal Register overload current protection and provides supplemental protection for high motor ambient temperature applications. Terminals for this input are provided with a factory jumper that must be removed if the PTC input is used. These terminals are located on TB1, Terminals 9 and 10.
PTC resistors are also found in other devices such as bearings, air receivers, oil or coolant reservoirs and air discharge systems that may require shutdown of the motor.
PTC Resistor Values:
Resistance must be greater than or equal to 750 Ω at 25ºC. If multiple resistors are used in the motor, the sum of all resistors in series must equal or exceed this value.
4.2.6.a External Over Load Relay Connection
OPTO
If an external Over Load Relay (OLR) is used (see Section 3.1.3.c and Appendix 5), connect the NC aux. contact of the OLR to the PTC input after removing the jumper. When the external OLR trips, the contact will open, opening the resistance input to the PTC circuit (the resistance goes to infinity). This indicates an immediate Over Load to the starter, which trips and displays it on the readout as
[ PTc ] to differentiate from the internal Thermal Over Load trip. If
multiple OLRs are used, i.e. multiple motors controlled by the same TE Series starter, simply wire the Aux Contacts in series as shown in Figure 4.2.6.a. See Appendix 5 for additional information.
NOTE:
An Emergency Stop Push Button or any other field device may be wired to the PTC input using NC contacts. When the contacts open, the starter will detect it as a PTC trip. Even if a PTC is used in the motor, field devices can still be added as long as the total circuit resistance is not exceeded.
This feature is especially useful when using Decel Control because
it will immediately shut off power to the motor even if Decel is active. If used this way, instruct the users as to the trip indication issues (i.e. the display will show [ PTc ] and the Overload LED will be on).

TB1, terminals 11 and 12, labeled “Opto”. The output Triac switch is rated for 10 - 250 VAC/DC, 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
R
permanently fixed at “Any Trip”, duplicating the Relay setting #16 as shown in Table 5.6.10.
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 TE 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 above). Toshiba recommends fusing all contacts with external fuses.
The relays are rated for 240 VAC, 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 TE Series detecting At-Speed, and returns to normal on Stop. At-Speed is determined by the TE 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 – 15 (as defined in Table 5.6.10) occurs.
All relays can be reprogrammed for a wide variety of functions. See Section 5.6.10 for additional relay programming details.

TE Series Digital Solid State Soft Starters 18 – 1250A
4.2.9 Bypass Contactor Control
On TE…-BP version (and NEMA 12 enclosed) 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.
4.2.9.a Independent Bypass Contactor Control
The TE…-BP Series starters use standard industrial contactors that can be controlled independent 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 the normal Shunt Duty (see section 1.2.3). Supplemental overload protection will be required (see section 3.1.3.c).
Units have external terminal blocks marked for this purpose (see Appendix 5 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 potential 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 TE Series, the At-Speed signaling can be programmed into any of the three Output relays above (section 4.2.8 and Table 5.6.10).
