Product Description
The RSMR is a microproces-
sor based soft starter for 3-
phase induction motors. A
rotary knob enables selection
from 10 pre-programmed
ramping profiles. The choice is
suggested by a list of popular
applications that corresponds
to the positions of the selec-
tor. No external supply is nec-
essary as starting and stop-
ping are controlled by closing
and opening a contact.

stop will be performed
according to the setting of
the rotary setup knob.
Soft-start and stop with
push-to-make and push-
to-break switches
(Fig. 4)
Pushing P1 soft-starts the
RSMR. Pushing P0 soft-
stops the RSMR. K is the
auxiliary contact of an exter-
nal mains contactor.
Control Diagrams and Applications
Fusing Considerations
(Fig.1)
This motor controller uses
semiconductors during run-
ning operation. Therefore the
semiconductors can be
damaged by short-circuit
currents. The best protec-
tion is with semiconductor
fuses.
Changing from Direct ON
Line start to soft start
(Line controlled soft-start)
(Fig. 2)
Changing a Direct On Line
start into a soft start is very
simple with the RSMR soft
starter:
1) Cut the cable to the motor
and insert the RSMR soft
starter.
2) Short the control input S0,
S1 with the link provided
3) Power up again - adjust
the start torque so the
motor starts turning
immediately after power is
applied.
When C1 is operated, the
motor controller will perform
soft-start of the motor. When
C1 is switched off, the motor
will stop (no soft-stop), the
motor controller will reset
and a new soft-start can be
performed.
Please note that the con-
troller does not insulate the
motor from the mains. A
mains contactor C1 is there-
fore needed.
Soft-start and stop with 2
position switch
(Fig. 3)
When P1 is closed, soft-start
of the motor will be per-
formed according to the set-
ting of the rotary setup knob.
When P1 is opened, soft-
