2.5    Mounting and Cleaning
When drilling or punching holes in the enclosure, cover the electrical a\
ssembly
to prevent metal filings from becoming lodged in areas which can cause
clearance reduction or actually short out electronics. After work is com\
plete,
thoroughly clean the area and reinspect the unit for foreign material. M\
ake
sure there is sufficient clearance (six inches) all around the unit fo\
r cooling,
wiring and maintenance purposes. To maximize effective air flow and cooling,
the unit must be installed with its heat sink ribs oriented vertically a\
nd running
parallel to the mounting surface.
Remove all sources of power before cleaning the unit.
In dirty or contaminated atmospheres the unit should be cleaned on a reg\
ular
basis to ensure proper cooling. Do not use any chemicals to clean the un\
it.
To remove surface dust use 80 to 100 psi, clean, dry compressed air only. A
three inch, high quality, dry paint brush is helpful to loosen up the dust prior
to using compressed air on the unit.

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 prot\
ection 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 th\
e 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 con\
dition,
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 maxi\
mum
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. In\
dividual
thermal overload relays must be installed on the motor leads going to ea\
ch
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 Ov\
erload
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 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 TD Series has reset itself a\
fter 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 (su\
ch
as the one provided in the packet with this manual) must be placed to b\
e
visible on the starter enclosure and/or the equipment as required by loc\
al
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 chara\
cteristics
of your motor and load.
NEMA Class trip curves are based on a common tripping point of 600% of r\
ated
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 se\
tting 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 NE\
MA
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 ha\
s reached
full speed based on closed loop feedback signals. When the At-Speed cond\
ition
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 det\
ails. MOTOR CONNECTED TO THIS EQUIPMENT MAY
START AUTOMATICALLY WITHOUT WARNING

4.1   Power Connections
Connect appropriate power lines to the unit input terminals marked L1, L\
2, L3.
Avoid routing power wires near the control board. Connect the motor lead\
s 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 t\
o the
load side of the unit. It may be necessary to use a load bank to test th\
e 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 lightnin\
g is a
significant problem, stationary air gap lightning arrestors should be co\
nsidered
and utilized on the input power source.

Refer to
the National Electrical Code for the proper ground wire sizing and be su\
re 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 boar\
d.
However, on units rated 150 Amps and above, TB1 us brought out to a duplicate

4.2.3  Two-Wire Connection
An alternate connection for unattended operation replaces start/stop pus\
h 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 res\
tarting 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 explai\
ned 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 contro\
l
board. The relays are rated for 240 VAC, 5 A and 1200 VA.
Factory settings for these relays are:
AUX 1 - Run / Stop (F050 = 1 )
AUX 2 - At Speed / Stop (F051 = 2)

4.2.6  Fault Signal
An optical AC switch triac driver is used for fault indication. This signal energizes
with the fault LED. The optical output is rated for 240 VAC, 50 mA (maximum).
4.2.7 Resetting Faults
To reset faults, press the RESET key on the keypad.
4.2.8  Enabling the Jog Function
Closing TB4 Pins 1 and 2 will enable the Jog feature. 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. See chapter 9 for main control board layout.
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).
A factory installed jumper is provided which allows the TD unit to operate if
external interlocks are not used. If this jumper is removed and an interlock is not
used, the TD unit will not function.

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 CurrentOver 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.
