Eaton S611 - Appendix G-Troubleshooting Guide; New Applications Checklist (Commissioning); Common Commissioning Fault Codes

S611 Soft Starter MN03902011E—May 2012 www.eaton.com 73
Appendix G—Troubleshooting Guide
This guide is intended to provide the information necessary
to successfully troubleshoot issues that may occur during
the operation of the S611 soft starter. The troubleshooting
sequence and fault codes (FC) are identified below in two
basic groups, New Applications and Existing Installations.
While any fault may occur in either category, experience has
shown that some faults are routinely experienced in one
category. The following information is intended to be a
reference guide to quickly move through the process to
achieve or restore operational status of the soft starter.
New Applications Checklist—During Commissioning
Note: It is not unusual for the S611 soft starter to trip in the
process of being commissioned as it is likely that one
or more parameter(s) setting are not appropriate.
120 Vac power applied

Sufficient minimum wattage and voltage value and inrush
capacity
Mains applied
●
