Predefined keys are used to perform critical functions:

Parameters to the DIM. The Configuration Parameters can
then be downloaded into other S811+ units.
To upload parameters: From the LCD DIM Setup Menu,
select “Upload Settings”
To download parameters: From the LCD DIM Setup Menu,
select “Download Settings”
To erase the parameter set stored in the DIM memory,
select “Flush” from the “Upload Settings” parameter.
Access Level (Password) Option
Levels of edit may be set to protect parameter settings.
●
Level 0—All parameters are Read Only
●
Level 1—Basic Editing
●
Level 2—Advanced Editing allows access to all editable
parameters.
●
Default Password for Levels 1 and 2 is 0. There is no
password required for Level 0.
DIM Removal
The DIM may be removed at any time (default) and the
S811+ will maintain functionality. The S811+ may be
configured to Fault Trip if the DIM is removed by disabling
the Removable DIM parameter located in the LCD DIM
Setup Menu.
Note:
If the S811+ received a START command from the
DIM, the unit will Fault Trip if the DIM is removed
while the unit is running. If the START command was
received from the control terminal block or a network
connection, the S811+ will continue to run.
Setup and Starting
Before You Begin
Be Aware of the Following:
1.
The Permissive terminal must have 24 Vdc applied to
ENABLE start or run commands from any source.
2.
To initiate a Stop remove the 24 Vdc
Permissive
terminal
input.
3.
For 2-wire local control, jumper
Permissive
and
Start
terminal inputs together.
4.
After an Overload Trip, the S811+ Soft Starter cannot be
restarted until the prescribed cool-down time has
elapsed. Review the START Inhibit times noted in
Appendix B
. Cycling 24 Vdc control power does not
reset the timer. If control power is removed, the soft
starter will retain the remaining time and will resume the
cool-down timing when power is again reapplied.
5.
When the S811+ internal bypass contactor(s) close, a
sound similar to contactor chatter may be heard. This
sound is the result of multiple contactors in some
models 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. During
normal operation, the S811+ will cycle the internal
bypass contactors at random intervals to clean the
contacts. During this operation, the contactors may be
heard to release then pull in again as described above.
Setup
After all power and control connections have been made and
you have read and understood the different operating modes
and protection features of the soft starter, set the Operations
and Protection parameters for your application. In many
cases, only the Motor FLA parameter requires adjustment to
the proper value, and all other parameters may be used with
the default values for the initial Start. Review the Protection
Options of the S811+
Appendix B
and adjust as required.
Stop Command
Start Command—0.3 seconds minimum to
recognize the signal. The delay may be
adjusted to 0.1 seconds. If set to 0, the Start
button on the DIM is disabled.
ESC—Navigates from the User Display to
the Parameter Edit Screens and is used to
return to any previous menu level without
saving changes.
