Types RSC -HD0M60/RSO.....

The microprocessor based

control module RSC-HD0M60

is used with output modules

RSO.... to achieve full wave

soft starting and soft stopping

of 3-phase induction motors.

When the motor is fully oper-

ating, the module delivers a

signal which can be used to

connect a contactor in parallel

with the output module,

thereby limiting the power dis-

sipation of the device and

eliminating the need for a large

heatsink. The power supply

unit MS1* has a built-in con-

trol relay for shunting the

motor controller when soft

starting is performed. The

standard control module is

multivoltage compatible and

features LED indication for

line ON and load ON.

time

The control module RSC-

HD0M60 is used with the out-

put module RSO.. to achieve

soft starting and soft stopping

of 3-phase induction motors.

Soft starting is achieved by

increasing the motor voltage

in accordance with the setting

of the ramp up time poten-

tiometer within the range of

0.5 to 30 s. Soft stopping is

achieved by decreasing the

motor voltage in accordance

with the setting of the ramp

down time potentiometer

within the range of 0.5 to 30 s.

The starting torque poten-

tiometer makes it possible to

adjust the starting level of the

motor voltage to a value at

which the motor starts to ro-

tate immediately when soft

starting is initiated. When the

motor is fully operating, an

output signal appears which

can be used to connect a by-

passing relay or contactor in

parallel to the output module,

thus limiting the need for cool-

ing.

Note: Only delta/star without

neutral.

Applications

RSC-HD0M60/RSO....

The output module RSO ..110

is recommended for motors

up to 22 kW @ 400 V. The

RSO ..110 is designed for use

in applications with high surge

current conditions. Care must

be taken to ensure proper

heat-sinking when the output

modules are to be used at high

nominal currents. Adequate

electrical connection between

relay terminals and cable

must be ensured.

Example 1:

Power dissipation -

RSO 40110:

Iload = 40 Arms = 111 W

See previous page.

Example 2:

Motor: 3 kW, ns = 1500 rpm,

3 x 400 V AC, 4-pole

TA: 50°C

Starting time: ≤5 s

The RSC-HD0M60 is used for

both applications. The RSO

..50, RSO ..25, RSO ..10 mod-

ules can b e used: RSO ..50, if

the starting current is un-

known for 5 s (starting time)

and a large safety margin is

required, RSO ..25/..10, if dur-

ing starting the current is low-

er. For RSO ..10 the maximum

current is 17 A for 5 s, and for

RSO ..25 the maximum cur-

rent is 39 A for 5 s.

In this application the start-

ing current is measured to be

only 17 A with a starting time

of 5 s. Consequently, an RSO

..10 is selected.

The min. heatsink is 1K/W,

and the power dissipation is

25 W.

This gives:

Control module:

RSC-HD.M60

Output module: RSO 4010

Heatsink:1K/W

Note: The thermal conditions

have now been designed for

the nominal motor current.

This means that the starting

time should be less than 10%

of the operating time of the

motor.

Connection to the mains

Since no motor protective

circuitry is included in the

RSC/RSO, the motor must

be protected in the usual

way, i.e. either by a thermal

relay, a PTC-resistor or a

Klixon bimetal temperature

switch near the motor wind-

ings.

If short circuit pr otection is re-

quired, fuses F1 to F3 should

be ultrafast and selected ac-

cording to the load integral

(I2t) of the RSO output module

and the motor load.

Note: The induced voltage

from the motor will prolong the

reset, depending on motor type

and load.

Manual start - stop function

If desired, an external control

circuit for manual starting and

stopping can be created by

using push buttons. When the

start button is pressed and

held until the lamp B1 is lit

(indicating that the motor is

now running), a holding con-

tact is made. The motor will

stop after activating the stop

button.

When the main contactor C1

switches on, and the control

switch S1 is closed, the motor

will soft-start. When S1 is

opened, the motor will soft-

Applications (cont.)

RSC-HD0M60/RSO

This circuit limits the power

dissipation of the SSR and

consequently eliminates the

need for a large heatsink, i.e.

the power dissipation is lim-

ited to the starting and

stopping periods. This is

achieved by switching a con-

tactor with the output signal

from the control module

RSC. In this case C2 is car-

rying - not switching - the

current and can therefore be

rated on the basis of the

thermal current data of the

contacts, which will result in

a smaller contactor.

Note: However, if C2 fails,

the temperature on the output

module RSO heatsink may

rise to an unacceptable level.

It is therefore advisable to

protect the RSO by means

of an optional temperature

limiting switch T1, which can

be inserted in the housing of

the output module.
