Type S811, Soft Starters with DIM
Product Description
1
Eaton’s S811 offers all
the popular features of the
1
S801, but adds enhanced
functionality with the new
1
DIM (Digital Interface
Module), communications,
1
metering, monitoring and
diagnostics capabilities.
1
Eaton’s line of S811 reduced
voltage soft starters is very
1
compact, multi-functional,
easy to install and easy to set
1
operating parameters.
Designed to control the
acceleration and deceleration
1
of three-phase motors up to
690V, the line is available
1
from 11–1000A.
The S811 is designed to be a
1
complete package combining
the silicon controlled
1
rectifiers (SCRs), bypass
contactor and overload in
1
one, very compact unit. The
S811 is available as a
1
component for panel
mounting, in motor control
centers or in enclosed control
1
(NEMA Type 1, 3R, 4, 4X, 7/9
and 12).

Application Description
Designed to control the
acceleration and deceleration
of three-phase motors, the
S811 soft starter uses SCRs
to control the voltage to soft
start and soft stop the motor.
After the motor is started,
internal run bypass
contactors close, resulting in
the motor running directly
across-the-line. The built-in
solid-state overload protects
the motor from overload
conditions with sophisticated
algorithms that model true
motor heating, resulting in
better motor protection
and fewer nuisance trips.
Advanced protective
and diagnostic features
reduce downtime.
A voltage ramp start or
current limit start is available.
Kick start is available in either
starting mode. The soft stop
option allows for a ramp stop
time that is longer than the
coast to stop time. The pump
control option provides a
smooth transition for starting
and stopping a motor and
eliminating the “waterhammer” effect that can
damage pipes, valves
and pumps.

The S811 offers an impressive
array of advanced protective
features. Not only are the
protective features selectable,
but many offer variable
settings and adjustable time
delays to ride through system
discrepancies.
The S811 has an easy to
use Digital Interface Module
(DIM) that allows the user to
configure the device and to
read system parameters and
monitor system values. The
DIM includes an LCD display
and keypad to scroll through
the various menus. The DIM
allows the user to modify
control parameters, enable
or disable protections, set
communication variables,
monitor system parameters
such as line voltages and
currents, and access the
fault queue.
The DIM can be removed
from the S811 and remote
mounted. Kits are available
to door mount the DIM,
enabling users to safely
configure, commission,
monitor and troubleshoot the
system at the electrical panel
without opening the
enclosure door. This will help
eliminate the possibility of an
arc flash incident.

Communications
The S811 has built-in
communication capabilities
through Eaton’s QC
(Quick Connect) Port.
QCPort™ enables the soft
starter to be connected
to a variety of networks,
including DeviceNet™,
EtherNet/Modbus, EtherNet/
IP and PROFIBUS. The
advantage of QCPort is that
multiple control components
can be connected to one
Eaton D77D gateway.

The gateway concentrates
data from the devices into a
single node. Configuration is
simple—a single press of the
gateway’s Auto Configuration
button sets the system up for
default operation. This
automatically configures the
I/O assemblies to the QCPort
system devices. The data
from these devices are then
assembled into single input
and output messages

The S811 communication
parameters can be configured
with the DIM or through the
Fieldbus using CH Studio
Component Manager.
Advanced communication
configuration settings provide
the system integrator with
powerful tools to facilitate
system optimization
