CAUTION STATEMENTS  
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.  
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.  
·
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.

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.  
TMS7-4075 ~ TMS7-4132  
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.

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  
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.  
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.

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

F1 Sem iconduct or Fuses  
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.

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.  
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.

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.

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

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.  
·
·
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  
Using a reduced MTC figure has the advantage  
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  
display, and adjusting the MTC parameter such  
that after a normal start which has been  
preceded by a period of running at maximum  
load, the calculated motor temperature is  
approaching 90%.

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

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).

Description  
TMS7 and reconnect the motor in 6 Wire.  
Symptom  
Cause  
Incorrect main control module.  
The TMS7 is fitted with an incompatible main control  
module.  
Uncontrolled start.  
Power factor correction capacitors  
connected to the TMS7 output. Remove  
any power factor correction from the output  
of the soft starter. Connection of power  
factor correction capacitors to the output of  
a soft starter can result in damage to the  
SCRs so they should be checked by using  
the SCR test described in section 9.4 Tests  
and Measurements.

Reset the TMS7. If the problem persists contact your  
supplier.  
9.2 Fault History  
Damaged SCRS. Verify soft starter  
operation using the SCR test described in  
section 9.4 Tests and Measurements.  
The TMS7 includes a Fault History Log that records the last  
eight trip events. Each trip is numbered. Trip number 1 is the  
most recent trip with trip number 4 being the oldest.  
Damaged firing circuit. Verify the TMS7  
SCR firing circuit using the Power Circuit

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.  
Remote control inputs not active. The  
TMS7 may be in local control mode. (Refer  
to Function 20. Local/Remote Operation)  
Faulty start signal. Verify any circuits  
connected to the TMS7 remote control  
inputs. The state of the remote circuits is  
indicated by the TMS7 remote control input  
LEDs. The LEDs are illuminated when there  
is a closed circuit. For there to be a  
successful start there must be a closed  
circuit across the start, stop and reset  
circuits.  
NOTE:  
The TMS7 records trips in the Fault History log  
immediately after they are detected, this requires  
control voltage to be present after the trip. Trips  
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  
lines as shown below.  
No, or incorrect control voltage. Ensure  
the correct control voltage is applied to the  
inputs A1, A2, A3.  
Restart delay active. The TMS7 cannot be  
started during the restart delay period. The  
period of the restart delay is set using  
Function 31. Restart Delay.  
Auto-reset function active. If there has  
been a trip and the auto-reset function is  
active the fault must be manually reset  
before a manual restart can be attempted.

measure the resistance between the  
input and output of each phase of the

TMS7 during run.  
1. Measure the voltage drop across each  
phase of the TMS7 (L1–T1, L2–T2,  
L3–T3). The voltage drop will be less  
than approximately 2 VAC when the  
TMS7 is operating correctly.  
Control input test  
This test verifies circuits connected to the  
TMS7 remote control inputs. (Start, Stop,  
Reset & FLC Select)  
1. Measure the voltage across each  
input. With the remote circuit closed  
there should be 0VDC measured. If  
24VDC is measured the switch/control  
is incorrectly connected or faulty.  
Start performance This test verifies correct operation of the  
test.  
TMS7 during start.  
1. Determine the expected start current  
by multiplying the settings made in  
Function 1. Motor Full Load Current  
and Function 2. Current Limit.  
2. Start the motor and measure the  
actual start current.  
3. If the expected start current and the  
actual start current are the same, the  
TMS7 is performing correctly.  
Power circuit test.  
This test verifies the TMS7 power circuit  
including the SCR, firing loom and control  
module.
