Description
Starting Torque Limiters are designed for the soft
starting of single and tree phase AC motors.
The TCI controller is easily installed between a
standard motor starter and the motor, and features
adjustable ramp-up time and initial torque.
The controller allows smooth starting of all AC
induction motors thus eliminating the damaging
effects of high starting torque surges.
Typical applications are conveyors, fans, compressors
etc.

Soft start function
As soon as the TCI controller is connected to
mains voltage, it soft starts the motor according
to the settings.
Ramp up
During ramp up, the controller will gradually
increase the voltage to the motor until it reaches
full line voltage. The motors speed will depend
on the actual load on the motor.
A motor with little or no load will reach full
speed before the voltage has reached its
maximum value.

Initial torque
The initial torque is used to set the initial starting
voltage. This way it is possible to adapt the
controller to an application requiring a higher
starting torque.

Wiring
Overload and
Short Circuit Protection
Starting Torque Limiter, type TCI (Soft Start)
Single phase motor
Three phase motor
Overload and short circuit protection is easily
achieved by installing a circuit breaker on the
line side of the motor controller. Select the circuit
breaker from the table according to motor full
load current.
Be aware of the maximum prospective short
circuit current breaking capacity. For further
information please refer to the data sheet on the
circuit breaker.

If required the controller can be protected
against overheating by inserting a thermostat in
the slot on the right-hand side of the controller.
Order: UP 62 thermostat 037N0050
The thermostat is connected in series with the
control circuit of the main contactor. When the
temperature of the heat sink exceeds 100oC the
main contactor will be switched OFF. A manual
reset is necessary to restart this circuit.
Mounting instructions
The controller is designed for vertical mounting.
If the controller is mounted horizontally the load
current must be reduced by 50%.
The controller needs no side clearance.
Clearance between two vertical mounted
controller must be minimum 80 mm (3.15”).
Clearance between controller and top and
bottom walls must be minimum 30 mm (1.2”).
