QUICK START

QUICK START

For simple applications TMS7 soft starters can be installed using
the three simple steps outlined below. For applications with
advanced control, protection or interface requirements a
comprehensive review of this Users Manual is recommended.

1. Installation & Connection

WARNING - ELECTRICAL SHOCK HAZARD

The TMS7 contains dangerous voltages when connected to
line voltage. Only a competent electrician should carry out
the electrical installation. Improper installation of the motor
or the TMS7 may cause equipment failure, serious injury or
death. Follow this manual and National Electrical Codes
(NEC®) and local safety codes.

1. Ensure the correct TMS7 model has been selected for the
connected motor and application type.

2. Mount the TMS7 making sure to allow adequate clearance
top and bottom for the free circulation of air through the
starter. (Refer to section 4.3 Mounting Instructions for further
detail.)

3. Connect the supply cables to starter input terminals L1, L2 &
L3.

4. Connect the motor cables to starter output terminals T1, T2
& T3.

5. Connect a control supply to starter input terminals A1 & A2
or A2 & A3. (Refer to section 6.2 Control Supply for further
detail).

4. Use the <UP> and/or <DOWN> keys adjust the FLC
setting to match the FLC of the connected motor.

5. Press the <STORE> key to store the new FLC setting.

6. Exit the programming mode by simultaneously pressing
then releasing the <FUNCTION> and <STORE> keys.

3. Operation

The TMS7 is now ready to control the motor. Motor operation
can be controlled using the <START> and <STOP> keys on the
TMS7 local control panel. Two other commonly used functions
that may be useful for basic installations are Function 2. Current
Limit and Function 5. Stop Ramp Ti me. These functions can be
adjusted in the same manner as described above. (For a more
detailed description of the programming procedure refer to
section 7.1 Programming Procedure.)

2. Programming

Basic application requires only that the TMS7 be programmed
with the connected motor's nameplate full load current (FLC). To
program the TMS7 with the motor's FLC do the following:

1. Put the TMS7 into program mode by simultaneously
pressing then releasing the <FUNCTION> and <STORE>
keys.

2. Select Function 1. Motor Full Load Current by holding
down the <FUNCTION> key and then press the <UP> key
until the display shows "1".

3. Release the <FUNCTION> key to display the currently
stored value of Function 1. Motor Full Load Current.

CAUTION STATEMENTS

Caution Statements

WARNING - ELECTRICAL SHOCK
HAZARD

The TMS7 contains dangerous voltages when
connected to line voltage. Only a competent
electrician should carry out the electrical
installation. Improper installation of the motor
or the TMS7 may cause equipment failure,
serious injury or death. Follow this manual
and National Electrical Codes (NEC®) and
local safety codes.

GROUNDING AND BRANCH
CIRCUIT PROTECTION

It is the responsibility of the user or person
installing the TMS7 to provide proper
grounding and branch circuit protection
according to the National Electric Code
(NEC®) and local codes .

It is the installers responsibility to adhere to all instructions in
this manual, to follow good electrical practice and to seek advice
before operating this equipment in a manner other than as
detailed in this manual.

This symbol is used throughout this manual to
draw attention to topics of special importance
to the installation and operation of the TMS7
soft starter.

• Ensure that the TMS7 is completely isolated from the power

supply before attempting any work on the unit.

• Do not apply voltage to the control input terminals. These

are active 12/24VDC inputs and must be controlled with
potential free circuits.

• Ensure contacts/switches operating the control inputs are

suitable for low voltage, low current switching ie, gold flash
or similar.

• Ensure cables to the control inputs are segregated from AC

power and control wiring.

• Entry of metal swarf into the cabinet can cause equipment

failure.

• Do not connect Power Factor Correction capacitors to the

output of the TMS7. If static power factor correction is
employed, it must be connected to the supply side of the
TMS7.

• Before installing the TMS7 without a line contactor ensure

such connection meets local regulations and by-laws.

• If installing the TMS7 within a non-ventilated enclosure a

bypass contactor must be utilised to prevent excessive heat
build-up.

• If installing a by-pass contactor ensure phase connections

are correctly made
ie L1B-T1, L2B-T2, L3B-T3

• Removing control voltage resets the thermal model.

The examples and diagrams in this manual are included solely for illustrative
purposes. Users are cautioned that the information contained in this manual

is subject to change at any time and without prior notice. In no event will

responsibility or liability be accepted for direct or indirect or consequential

damages resulting from the use or application of this equipment.

Input/Output Output Input

To adjust the bus bar configuration first remove the TMS7 cover
and main control module. Next loosen and remove the bus bar
fixing bolts. The bus bars can then be removed and reinstalled
into the starter in the desired configuration. The fixing bolts
should then be refitted and tightened to a torque of 8.5NM.

When re-orienting bus bars L1, L2, L3 the current transformers
must also be relocated.

Care must be taken to ensure that foreign matter does not
contaminate the jointing compound and become trapped
between the bus bar and its mounting plate. If the paste does
become contaminated, clean and replace with a jointing
compound suitable for aluminium to aluminium, or aluminium to
copper joints.

4.3 Mounting Instructions

Models TMS7-4007 ~ 4132 can be wall mounted or installed
inside another enclosure. These models can be mounted side
by side with no clearance but a 100mm allowance must be
made top and bottom for air intake and exhaust.

INSTALLATION

4.4 Ventilation

When installing TMS7 starters in an enclosure there must be
sufficient air flow through the enclosure to limit heat rise within
the enclosure. Temperature within the enclosure must be kept
at, or below, the TMS7 maximum ambient temperature rating.

If installing an TMS7 within a totally sealed enclosure a bypass
contactor must be employed to eliminate heat dissipation from
the soft starter during run.

Soft starters dissipate approximately 4.5 watts per amp. The
table below shows air flow requirements for selected motor
currents. If other heat sources are installed in an enclosure
along with the TMS7 an additional air flow allowance must be
made for these items. Note that heat generation from
semiconductor fuses, if used, can be eliminated by installing
these within the bypass loop.

POWER CIRCUITS

Power Circuits

5.1 Overview

TMS7 starters can be wired with a number of different power
circuits depending on application requirements.

5.2 3 Wire Connection

This is the standard connection format. Supply voltage is
connected to the starter input terminals L1, L2 & L3. The motor
cables are connected to the soft starter output terminals T1, T2
& T3.

SUPPLY

Legend
K1 Line Contactor

5.3 3 Wire Connection (Bypassed Operation)

TMS7 starters can be bypassed while the motor is running.
Special terminals (L1B, L2B, L3B) are provided for connection of
the bypass contactor. Use of these terminals enables the TMS7
to continue to provide all protection and current monitoring
functions even when bypassed.
The TMS7 Run Output (Terminals R34 & R33) should be used
to control operation of the bypass contactor. The bypass
contactor can be AC1 rated for the motor full load current.

5.4 6 Wire Connection

TMS7 units are capable of 6 Wire (Inside Delta) connection as
well as 3 Wire connection. When connected in this configuration
the soft starter carries only phase current, this means the motor
FLC current can be 50% greater than the soft starter’s FLC
current rating.

Connect the three OUTPUT terminals (T1, T2, T3) of the TMS7
to the motor windings ensuring that the connections are made to
one end of each winding only. It is imperative to connect the
output of the TMS7 to the same end of each winding and this is
usually marked on the motor terminations.

MOTOR TERMINALS
6 WIRE CONNECTION

T1

The six terminations to the motor windings are usually arranged
in two rows of three so that the links can be fitted across from
the top three terminations to the lower terminations. In this case
connect the TMS7 to the top terminations only. Connect the
other three motor terminals to the input of the TMS7 in a manner
that connects the end of each winding to a different phase from
the input.
This is most easily achieved by replacing each delta link in the
motor terminal box by one phase of the controller. For example
if the delta links are fitted U1-V2,V1-W2,W1-U2

- Connect the incoming phases to L1,L2,L3 on the TMS7.

- Connect the TMS7 to the motor. T1-U1, T2 -V1, T3 -W1

- Connect the other motor terminals to the TMS7’S input W2-L1,
U2-L2, V2-L3

5.6 Power Factor Correction

If static power factor correction is employed, it must be
connected to the supply side of the soft starter.

CAUTION:
Under no circumstance should power factor
correction capacitors be connected between the
soft starter and the motor. Connecting power
factor correction capacitors to the output of the
soft starter will result in damage to the soft
starter.

TMS7 SERIES ME00070B 11

POWER CIRUCITS

5.7 Line contactors

The TMS7 is designed to operate with or without a line
contactor. In many regions there is a statutory requirement that
a line contactor be employed with electronic motor control
equipment. From a safety point of view, this is the preferable
option, however is not necessary for starter operation. An
additional benefit gained by use of a line contactor is isolation of
the starter SCR’s in the off state, when they are most
susceptible to damage from voltage transients.

The TMS7 can directly control a line contactor via the Main
Contactor Control output.

As an alternative to a line contactor, either a circuit breaker with
a no volt release coil operated by the TMS7 trip output, or a
motor operated circuit breaker can be considered. If a motor
operated circuit breaker is used as a line contactor, the potential
delay between the breaker being told to close and phase power
being applied to the TMS7 could cause the TMS7 to trip on
installation faults. Closing the motorized breaker directly and
using the breaker’s auxiliary contacts, or preferably a slave relay
with gold flash contacts, to control the TMS7 can avoid this.

Line contactors must be selected such that their AC3 rating is
equal to or greater than the full load current rating of the
connected motor.

MTC = 5 Sec

MTC = 20 Sec

Adjustment: Function 3 Minimum Current and Function 4 Start
Ramp Time are used together to activate and control the Ramp

Start mode.
If the Ramp Start mode is required, set the Minimum Current so

that the motor begins to accelerate immediately a start is
initiated. Ramp Start mode is not required, set the Minimum
Current equal to the Current Limit.

Ramp Start mode should be considered in preference to Current
Limit start mode in applications where:

• Required start torque can vary from start to start. For
example conveyors may start loaded or unloaded. In this
case set Function 3 Minimum Current to a level that will
start motor in the light load condition and Function 2
Current Limit to a level that will start the motor in the high
load condition.

• Starting time of an easily broken away load needs to be
extended, for example pumps.

• A generator set supply is limited and a slower application
of load will allow greater time for the generator set to
respond.

4. Start Ramp Time

Range: 1 – 30 Seconds
Default Setting: 1 Second
Description: Sets the ramp time for the Current Ramp start

mode.
Adjustment: Set the Start Ramp Time to optimise start

performance.

5. Stop Ramp Time

Range: 0 – 100 Seconds
Default Setting: 0 Second (Off)
Description: Sets the soft stop ramp time for soft stopping of

the motor.
Adjustment: Set the Stop Ramp Time to produce the desired

motor stopping performance.
Two soft stop modes are provided by the TMS7. Use Function

10. Soft Stop Mode to select the desired mode.
If utilising the Soft Stop function and a line contactor, the

contactor must not be opened until the end of the stop ramp
time. The TMS7 programmable outputs A,B or C can be set for
control of the line contactor. Refer Functions 21, 22, 23 for
programmable output assignment details.

Default Setting: 10 Seconds

Time or Maximum DOL Start Time. This information is available
from the motor data sheet or direct from the motor supplier.

NOTE:
The TMS7 motor thermal model assumes a
locked rotor current of 600%. If the connected
motor’s locked rotor current differs from this,
greater accuracy can be achieved by using a
normalised MTC figure. A normalised MTC
figure can be calculated as follows:

NOTE:
Setting Function 6 Motor Trip Class according
to the motor’s actual thermal capacity allows
safe use of the motor’s full overload capability
both to start the load and ride through overload
conditions. Additionally, a more conservative
approach can be taken by setting a reduced
MTC for easy to start loads that will not
experience transient operating overloads as a
part of normal operation.

of maximising motor life. The life of a motor is
strongly influenced by its maximum winding
temperature, with a 'rule of thumb' stating that
the expected life span of a motor is halved for
every ten degree rise in temperature. The
temperature rise is dependent on the motor
losses and the motor cooling. The highest
stress on the motor is during start, and can be
minimised by restricting the duration and
frequency of starts. A reduced MTC setting
(Function 6) will also cause the TMS7
protection to operate before the motor is
thermally stressed.

A suitable reduced MTC figure can be
established by observing the modeled motor
temperature as shown on the TMS7 LED

that after a normal start which has been
preceded by a period of running at maximum
load, the calculated motor temperature is
approaching 90%.

Description:

For high inertia loads that require more braking torque than is available from the D.C.Brake feature, the TMS7 can be configured for 'Soft
Braking'.
In this application the TMS7 is employed with forward run and braking contactors. On receipt of a start signal (pushbutton S1) the TMS7
closes the forward run contactor (K1M) and controls the motor according to the programmed Primary Motor Settings.
On receipt of a stop signal (pushbutton S2) the TMS7 opens the forward run contactor (K1M) and closes the braking contactor (K2M) after a
delay of approximately 2-3 seconds (K1T). K3A is also closed to activate the Secondary Motor Settings which should be user programmed
for the desired stopping performance characteristics.
When motor speed approaches zero the shaft rotation sensor (A2) stops the soft starter and opens the braking contactor (K2M).

Function Settings:

- Function 23. Relay Output C Functionality = 0 (Assigns the Trip function to Relay Output C)

- Functions 1~9 (Sets starting performance characteristics)

- Functions 80~88 (Sets braking performance characteristics)

The TMS7 can be configured for control of dual speed Dahlander type motors. In this application the TMS7 is employed with a High Speed
contactor (K1M), Low Speed contactor (K2M) and a Star contactor (K3M).
On receipt of a High Speed start signal the High Speed contactor (K1M) and Star contactor (K3M) are closed. The TMS7 then controls the
motor according to the Primary Motor Parameter set. (Function Numbers 1~9)
On receipt of a Low Speed start signal the Low Speed contactor (K2M) is closed. The relay contact across Input A is also closed causing
the TMS7 to control the motor according to the Secondary Parameter set (Function Numbers 80~88).

The Fault History can be viewed by selecting Function 101.
Fault History and using the <UP> and <DOWN> keys to scroll
through the Fault History.

NOTE:
The TMS7 records trips in the Fault History log
immediately after they are detected, this requires

caused by or involving a loss of control voltage
may not be recorded.

A ‘marker’ can be inserted into the Fault History log to identify
trips that have occurred after placement of the ‘marker’. To
insert a ‘marker’ enter the programming mode and move to
Function 101. Fault History . Then simultaneously depress the
<UP> and <DOWN> and <STORE> keys. The marker is added
as the most recent fault and is displayed as three horizontal
