The micro processor based
control module RSC-AAM60
is used with output modules
RSO... to achieve a voltage
controlled soft start/soft stop
of 3-phase motors and a pos-
sibility for energy reduction
when e.g. a fan is running with
a variable capacity. This func-
tion is achieved by controlling
the control module with a cur-
rent between 4 and 20 mA (0
and 20 mA). The output mod-
ule can be selected according
to the rated operational volt-
age and the size of the load.
This phase angle controlled
soft-start unit can be used for
pumps, fans, heaters, lights
and many other applications.
LED indications for line ON
and load ON gives a clear sta-
tus indication.

Mode of Operation
The control module RSC-
AAM60 is used with the out-
put module RSO..... to
achieve analog control of 3-
phase induction motors.
Soft starting is achieved by
increasing the motor voltage
in accordance with the input
current. Soft stopping is
achieved by decreasing the
motor voltage in accordance
with the input current.
When the motor is running
idle, the motor voltage can
be reduced by lowering the
input current, whereby ener-
gy is saved.
Heating elements can also
be controlled with the
RSC/RSO with the use of
appropriate filters.

overheating. Therefore the chart also states the maximum
switching temperature (70, 80 or 90 C) for the optional

RSC -AAM60/RSO....
Energy saving for motors in idle mode
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 relays are to
be used at high nominal cur-
rents. Adequate electrical con-
nection between relay termi-
nals and cable must be ensured.
Example 1:
Power dissipation -
RSO 40110:
I
load
= 40 Arms = 111 W
See previous page.
Example 2:
Motor: 3 kW, 4 HP
3 x 400 VAC, 4-pole
T
A
: 50
C
Starting time:
5 s
For this application RSC-AAM60
must be used. The output
module RSO4025 is selected
according to the Selection Guide.
The smallest heatsink
required is 1 K/W, and the
power dissipation is 25 W.
This gives:
Control module:
RSC-AAM60
Output module: RSO 4025
Heatsink:1K/W
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 windings.
If short circuit protection is re-
quired, fuses F1 to F3 should
be ultrafast and selected ac-
cording to the load integral
(I
2
t) of the RSO output module
and the motor load.
When motors are running idle,
it not necessary to maintain a
full magnetic field, as is the
case when the motor has to
produce full torque. By lower-
ing the motor voltage, power
losses inside the motor are
also reduced.
Transient voltage protection
With an unfiltered main supply,
voltage transient may occur.
Since these transients could
have a high energy content, it
is advisable to use varistors
to protect the output module.
The varistors are already
mounted in the RSO output
module and they are selected
according to the rated opera-
tional voltage.
When the motor is idle, d1 will
switch the control current from
I
1
> 20 mA to I
2
, which is
adjusted to a value at which
the motor is still running at full
speed, but at a lower voltage.
Please remark that this type of
phase-angle controlled voltage
reduction, demands additional
filtering to fulfill EMC regulations.

RSC -AAM60/RSO.....
In order to achieve a 4 to 20
mA signal from a 12 or 24
VDC source, a resistor and a
potentiometer should be con-
nected in series with the volt-
age source and the RSC con-
troller.
We define the I
max.
to be e.g.
24 mA, which means that the
series resistors must be:
R
1
(12 V) = U/I - Rint =
12 V/24 mA - 250
= 250
R
1
(24 V) = U/I - Rint =
24 V/24 mA - 250
= 750
If the minimum current is
defined to be e.g. 2.4 mA
and the 250
Rint input
resistance of the RSC is
also calculated in:
R
2
(12 V) = U/I - R
1
- Rint =
12/2.4 - 250 - 250 = 4500
R
2
(24 V) = U/I - R
1
- Rint =
24/2.4 - 750 - 250 = 9000
