Potentiometers
With the 4 potentiometers, the user can adjust the different
times and torques infinitely variable, depending on the operating
mode.
After the operating mode and the time range have been set with
the dip switches, the following table can be used to set the
respective function of the potentiometer and the pertaining time
range.
Note: It must be observed that times and torques of a soft
starter can only be adjusted under the load conditions of the
application to be realized. Accordingly, the time ranges in
seconds only apply under load. The scales serve as
benchmarks and are not to be considered defined values in sec.
and Nm.
3.4.3 Slide switch for automatic operation
The slide switch is used to switch the automatic operation on or off. It refers to the characteristics of switching
on again after the motor starter has cut off because of excess temperature of the motor.
[ON]
Switching off: OK message (signal OK at low) is removed in case of excess temperature. The motor is
automatically switched off by SK 150E.
Switching on again: The drive will not start automatically if excess temperature is no longer present. The
control signal [RUN] must first be switched off and then on again or, alternatively,
the slide switch is pushed to [OFF] and again to [ON]. Attention: The drive starts
immediately!
[OFF]
Switching off: OK message (signal OK at low) is removed in case of excess temperature. The motor is
not automatically switched off by SK 150E.
Switching on again: The OK message is switched high again when the excess temperature is no longer
present. The motor would start-up even in case of excess temperature!
