Figure 17: Current Limit Start
Kick Start — This feature provides an initial boost in
torque to overcome the initial static friction in some
applications. The level of torque boost is set by the Kick
Start Torq parameter and the duration of the “kick” is set
by the Kick Start Time. Setting the Kick Start Time to 0
disables this feature.
Soft Stop — This feature is used for applications that
require a controlled extended stop. It is designed for high
frictional loads that tend to stop suddenly when voltage to
the motor is removed.
Note: This function will not stop the motor any faster than
it would normally take to coast to a stop under load.
Figure 18: Soft Stop
IMPORTANT:
Note the following items before you begin.
1. P and Hand inputs must be energized (24V DC) to
enable starting of the soft starter from the terminal
block.
2. To Start: Apply 24V DC to Input 1 while the P input is
energized.
3. To initiate a Stop, remove the P input.
4. For 2-wire control, jumper P and Input 1 together.
5. After an Overload Trip, the S811 Soft Starter cannot
be restarted until the prescribed cool-down time
has elapsed. Cycling power does not reset the timer.
If 24V DC power is removed, the soft starter will
remember the remaining time and will resume the
cool-down timing when power is again applied.
6. On Frames R, T, U and V when the S811 goes into
bypass, a sound similar to contactor chatter can be
heard. This sound is the result of multiple contactors
closing one after the other in a very short period. It is
normal operation intended to reduce the surge
current requirements of your power supply.
Quick Setup
Configuring the S811 Soft Starter
After all power and control connections have been made
and you have read and understood the different operating
modes of the soft starter, it is time to program it for your
application. As shipped from the factory, the S811 Soft
Starter’s default configuration is sufficient for basic
operation but may require some configuration to “tune” it
for your application. The following basic setup procedure
assumes you understand how to navigate through the
S811’s parameter menu using the Digital Interface Module
(DIM) and that the S811 is in its Factory (Out-of-Box) state.
Refer to the S811 User Manual (Pub. No. MN03902002E),
Chapter 8, for a detailed explanation of the DIM.

Danger
The S811 has the ability to respond to commands from an automated network
controller. Consequently the soft starter may start unexpectedly in response to
these commands. To insure the safety of personnel and equipment, always
remove power before accessing the electrical and/or mechanical equipment.
Danger
Le S811 à la capacité de répondre aux commandes d’un contrôleur de réseau
automatisé. Donc le démarreur progressif peut démarrer soudainement en
réponse à ces commandes. Pour s’assurer la sécurité du personnel et de
l’équipement, toujours débrancher l’alimentation avant d’accéder à l’équipement
électrique et/ou mécanique.
Peligro
El S811 tiene la capacidad de responder a comandos de un controlador de red
automatizado. Por lo tanto, el arrancador suave podría arrancar de improviso en
respuesta a estos comandos. Para garantizar la seguridad del personal y del
equipo, siempre desconecte la energía antes de acceder al equipo eléctrico o
mecánico.
