Changing from Direct ON
Line start to soft start
(Line controlled soft-start)
(Fig. 1 & Fig. 2)
Changing a Direct On Line start
into a soft start is very simple
with the RSE soft-starting re-
lay:
1) Cut the cable to the motor
2) Connect control input to two
3) Power up again - adjust the
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.

Soft-start and soft-stop
(Fig. 3)
When S1 is closed, soft-start
of the motor will be performed
according to the setting of the
ramp-up potentiometer and
the setting of the initial torque
potentiometer. When S1 is
opened, soft-stop will be per-
formed according to the set-
ting
potentiometer.
