Supply Specifications General Specifications

This motor controller is in-

tended to be used to softstart

single phase run capacitor

induction motors and thereby

reduce the stress or wear on

gear and belt/chain drives and

to give smooth operation of

machines. Soft starting is

achieved by controlling the

motor voltage. During running

operation the semiconductor is

bypassed by an internal elec-

tromechanical r elay.

The initial torque can be ad-

justed from 0 to 85% of the

nominal torque.

The softstart time can be ad-

justed from 0.5 to appr ox.

6.5 s.

A green LED indicates supply.

Two yellow LEDs indicate

Ramp up and Running mode.

Overload protection is not pr o-

vided in this motor controller

and must therefore be in-

stalled separately.

The controller is only switching

L1 line. The L2/N and L3 are

continuously connected to the

load.

Changing from Direct ON

Line start to soft start

(Line controlled soft-start)

(Fig. 1 )

Changing a Direct On Line

start into a soft start is very

simple with the RSE soft-

starting relay:

1) Cut the cable to the motor

and insert the RSE relay.

2) Connect control input to the

two mains lines.

Set initial

torque to minimum

and

ramp up potentiometer to

maximum.

3) Power up again - adjust the

start torque so the motor

starts turning immediately

after power is applied, and

adjust ramp time to the

appropriate value.

When C1 is operated, the

motor controller will perform

soft-start of the motor. When

C1 is switched off, the motor

will stop, the motor controller

will reset and after 0.5 s a new

soft-start can be performed.

Please note that the controller

does not insulate the motor

from the mains. Contactor C1

is therefore needed as a ser-

vice switch for the motor.

Time between rampings

To prevent the semiconduc-

tors from overheating, a cer-

tain time between ramping

should be allowed. The time

between rampings depends

on the motor current during

ramping and ramp time (see

tables below).

Note:

Table is valid for ambient

temperature 25°C. For higher

ambient temperature add

5%/°C to values in the tables.

The shaded areas in the tables

are for blocked rotor. Do not

repeat rampings with blocked

rotor.

Fusing Considerations

The motor controller provides

by-passing of the semicon-

ductor during running opera-

tion. Therefore the semicon-

ductor can only be damaged

by short-circuit currents dur-

ing ramp-up and ramp-down

function.

A single-phase run capacitor

induction motor with correctly

installed and adjusted over-

load protection does not short

totally between lines or direct-

ly to earth as some other

types of loads, e.g. heater

bands. In a failing motor there

will always be some part of a

winding to limit the fault cur-

rent. If the motor is installed in

an environment where the

supply to the motor cannot be

damaged, the short circuit

protection can be considered

to be acceptable if the con-

troller is protected by a single-

pole thermal-magnetic over-

load relay.

If the risk of short circuit of the

motor cable, the controller or

the load exists, then the con-

troller must be protected by

ultrafast fuses, e.g. Ferraz 660

gRB 10-25. Fuseholder type

PST 10.

3-phase torque r eduction

When C1 is closed, a torque

reduced start of the 3-phase

motor will be performed

according to the setting of the

ramp-up potentiometer, and

the setting of the initial torque

potentiometer.

Warning:

When the motor is stopped

C1 must be open to remove

all 3 phases from the motor.

This is necessary to avoid 2-

phase running of the motor.
