S811+ Operating Configuration
S811+ Soft Starter MN03900001E—November 2012 35
Protection Parameters
In addition to motor overload protection, the S811+ has
many programmable features designed to protect the motor.
●
Incoming Line Phase Reversal, Loss, Imbalance, Over
Voltage, and Under Voltage trips.
●
Selectable Overcurrent trip levels.
●
Stall and Jam trips.
A Phase Reversal Fault is a likely fault condition on new
installations. It can be addressed by either changing the
Phase Sequence from ABC to ACB, disabling phase rotation
monitoring, or removing Mains power and switching the
incoming line connections at L1 and L2 of the S811+.
For troubleshooting purpose trips are recorded, as they
occur, in the S811+’s Fault Log.
Apply the Mains voltage and verify that no fault is present.
The S811+ indicates faults with a Fault message and
corresponding Fault Code in the DIM.
When a Fault Trip occurs, the Fault Trip screen will
automatically display on the DIM. Fault Trips are displayed
with the most current Fault at the top of the list. If the Fault
is no longer active, the S811+ may be Manually reset by
pressing the corresponding soft key on the DIM.
Fault History
The Fault history may be displayed at any time by pressing
the Faults soft key on Digital Interface Module (DIM).
Fault Codes
For additional details on troubleshooting fault codes and
fault conditions, please refer to Troubleshooting and
Appendix I.
Fault Trips
The S811+ is configured from the factory with most
protection parameters enabled. Selected protection
parameters may be changed to Fault Warnings in which case
the fault is detected and reported, but the soft starter
remains in operation. It is recommended that all appropriate
protection parameters are enabled for proper operation and
protection of the soft starter and the load.
Fault Warnings
Selected S811+ Configuration and Protection parameters
may be configured to provide warning indications only. If a
parameter is set to Warning status, the unit will not trip if
operation is not within the protection level of the parameter.
A Fault Warning is displayed on the DIM by the “Warning”
message being toggled with the current motor status in the
status bar of the DIM.
