TD Series Digital Solid State Soft Starter 48 - 1250A
1.1 General
The TD 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 60 seconds (compared to
350% for 30 seconds from other manufacturers). The TD Series features
smooth, stepless ramp control which reduces motor inrush current and
excessive wear on the mechanical drive train components. In addition to
having easy to understand diagnostic LEDs, the TD Series includes a
programmable keypad for setting operating parameters for the ideal
starting cycle. Starting torque, ramp time, current limit, dual ramp, and
decel control are standard features on the TD Series. 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 TD Series includes solid state electronic overload protection in
addition to numerous other protective features. It is factory wired for 120
VAC control voltage and two or three-wire start/stop control (Units can
also be ordered with 240 VAC control voltage if required). Programmable
auxiliary contacts and provisions for interlocking are also included.

Chapter 3 - Motor Overload Protection
3.1 Solid State Overload Protection
The TD Series Starter provides true U.L. listed I2T Thermal Overload Protection
as a built-in function of the main digital processor. For maximum protection it
simulates the tripping action of a bimetallic overload relay, with the accuracy and
repeatability of a digital control system, yet is adjustable over a wide range and
can be easily programmed for different trip curves.
3.1.1 Thermal Memory
The TD Series microprocessor uses a sophisticated “Thermal Register” to keep
track of motor heating and cooling over time regardless of the starter’s power
status. The TD 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.
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. 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 will provide maximum
protection yet eliminates nuisance tripping.
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: If F001 is left at the factory default, the unit will not operate. If the
user attempts to start the TD without entering the motor nameplate
FLA into this Function, the TD will Fault, and the display will read
“nFLA” (for no Full Load Amps).
3.1.3 Disabling the Overload Protection
The Overload Protection feature can be disabled if absolutely necessary. When
using external devices such as Motor Protection Relays or when the TD Series
is wired downstream from an existing starter, this feature can be disabled to
prevent conflicts with external overload protection devices. When the TD Series
is controlling multiple motors, Overload Protection must be disabled. Individual
thermal overload relays must be installed on the motor leads going to each
motor. To disable the Overload Protection function, use F005. (See Section 5.)
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. 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.
WARNING

TD - Series
- 8 -
TD Series Digital Solid State Soft Starter 48 - 1250A
3.1.3.b Automatic Reset
If Automatic Reset is necessary, change from Manual Reset toAutomatic 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 TD Series has reset itself after the cool
down period.
Two-wire control systems may restart without warning when Auto Reset
is selected. Extreme caution should be exercised. To prevent automatic
restarting with two-wire control systems, use external interlocking to
provide sufficient warning and safety to operators. A Warning Label (such
as the one provided in the packet with this manual) must be placed to be
visible on the starter enclosure and/or the equipment as required by local
code.
3.2 NEMA Class Trip Curves
The TD Series Soft Starter provides six NEMA Class trip curve options: 5, 10,
15, 20, 25, and 30. Program the appropriate curve according to the characteristics
of your motor and load.
NEMA Class trip curves are based on a common tripping point of 600% of rated
current. 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%. The factory default setting of
Class 10 will trip in 10 seconds at 600%.
3.2.1 Dual Overload Trip Curves
The TD Series Soft Starter provides two separate Overload Trip Protection Curves,
one for starting and one for running conditions. Programming a higher NEMA
Class overload during start (ramp-up) will eliminate nuisance tripping in higher
inertia or high friction loads.
The starter’s At-Speed detection circuit determines when the motor has reached
full speed based on closed loop feedback signals. 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 for programming details.

4.1 Power Connections
Connect appropriate power lines to the unit input terminals marked L1, L2, L3.
Avoid routing power wires near the control board. Connect the motor leads to the
unit terminals marked T1, T2, T3. Refer to NEC standards for wire length and
sizing. Never interchange input and output connections to the unit. This could
cause excessive voltage in the control logic circuit and may damage the unit.
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.
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. Note that line voltage will appear across the output terminals if
there is no motor or load connected to the unit. In areas where lightning is a
significant problem, stationary air gap lightning arrestors should be considered
and utilized on the input power source.
TD Series Unit
Power Connections
4.1.1 Grounding
Connect the ground cable to the ground terminal as labeled on the unit. Refer to
the National Electrical Code for the proper ground wire sizing and be sure that
the ground connector is connected to earth ground.
4.2 Control Connections
4.2.1 Control Power Connections
Separate 120VAC supply is required (order 240 VAC if required). The control
voltage should be connected to pins 1 and 6 of TB1. This control voltage must be
customer supplied, unless an optional control power transformer has been supplied
with the unit. The terminal block TB1 is located on the main power board.
However, on units rated 150 Amps and above, TB1 us brought out to a duplicate

(normally open) start button between pins 4 and 5 of terminal block TB1.
4.2.3 Two-Wire Connection
An alternate connection for unattended operation replaces start/stop push buttons
by connecting a maintained contact closure between pins 3 and 5 on TB1. When
the maintained contact is used for start/stop it is necessary 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.
When two-wire connection method is used, the user’s control circuit
must be interlocked to prevent automatic restart when protective
devices reset. Refer to section 3.1.3.b.
4.2.4 Relay Contacts
All the relay contacts are FORM C common (N.O., N.C.), except the optical
triac output. TOSHIBA recommends fusing all contacts with external fuses. TB2
is the terminal block for all auxiliary contacts. Each contact is explained in the
following sections. See Chapter 9 for main control board layout.
4.2.5 Programmable Relays
Three programmable relays are on TB2 which is located on the main control
board. The relays are rated for 240 VAC, 5 A and 1200 VA.
Factory settings for these relays are:

4.2.9 Enabling the Dual Ramp Feature
Closing TB4 Pins 1 and 3 will enable ramp 2. The dual ramp feature is useful in
instances where a load changes such as 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.
4.3 Interlock Connection
TB1 provides a connection point for an external user N.C. (normally closed)
interlock device between pins 2 and 3. (Examples of the use of this interlock
connection would be for conditions such as low oil, high temperature, or excess
vibration from user supplied devices).

Two or more power poles are shorted and current is passing to the
motor while in the off mode. For positive motor protection, an auxiliary
relay should be be programmed for "Shunt Trip" and should be
interlocked with a shunt trip breaker or in-line contactor. (In the event o
f
a shunt trip, do not re-power the unit without repairing the power poles.)
Over Current
Over Current LED illuminates for two sets of fault conditions: over
current and short circuit.
If unit experiences output current (of any phase) in excess of the value
programmed in F034 (over current trip %) for the time period specified
in F035 (over current trip delay), this LED will illuminate and either
oCA, oCC, or oCd will be displayed.
If unit experiences a short circuit fault condition, the Over Current LED
illuminates and either SCA, SCC, or SCd will be displayed. This trip is
fixed at 10 times the full load motor current and is not adjustable.

5.3 Display Modes
There are three modes of display: the Status Display mode, the Program mode,
and the Fault mode.
5.3.1 Status Display Mode
The Status Display Mode displays three phase motor current information and the
thermal capacity remaining.
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 either Phase B or C. While viewing Phase A, press
the UP arrow once to view Phase B or twice to view Phase C current.
•[H000] Scroll up to display the “H”. This indicates that this value is the
remaining thermal capacity of the motor (as a percentage i.e. H070 =
70% remaining thermal capacity)
Reading Phase Current and Thermal Capacity (See Example)
[0120.] Indicates that Phase A is
drawing 120 amps.
Press the UP arrow.
[0121] Indicates that Phase B is
drawing 121 amps.
Press the UP arrow.
NOTE: Decimal points are not
present in the readouts
for Phase B and Phase C.
[0120] Indicates that Phase C is
drawing 120 amps.
Press the UP arrow.
[H051] Indicates that the motor has
51% of its thermal capacity
remaining.
5.3.2 Program Mode
Use the Program Mode to view or change Function (Fn) settings.
To enter the Program Mode, press the [Fn] key once. The first time you enter
Program Mode after power has been cycled to the starter, the initial function
[F001] should display with the selected digit flashing. If the TD Soft 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.
Program Mode:
•[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 step.
