Viewing Event Logs
Event Category Legend:
OK = Operating within normal parameters
ERROR = Operating outside of normal parameters (The control requires immediate
servicing. Contact the local S&C Sales Ofce.)
TRIP = Shows the Magnetic Latching Solenoid (MLS) voltage upon trip
POWERUP = Shows when the overcurrent control was powered on
The overcurrent control tests vital subsystems at power up and periodically thereafter to
ensure the control is working properly. The Control Self-Test Report displays the present
status of every testable hardware and software component. It can be run on demand by
refreshing the Control Self-Test Report.
The Control Self-Test Report will be used mainly by S&C Electric Company to help
troubleshoot any problems with the overcurrent control. If any parameter records an
ERROR, the control will be in an error state and the Control Enabled indicator on the
Status screen will be solid green, indicating the primary functions of the control are
inhibited. Report any ERROR messages to S&C Electric Company. (Contact your local
S&C Sales Ofce or the S&C Global Support and Monitoring Center at 1-888-762-1100 or
1-773-338-1000 outside the U.S. for details.)
To view the self-test report, open the Control Self-Test Report menu under the
Event Log tab. To refresh the data in the Control Self-Test Report, click on the Refresh
button at the bottom of the Control Self-Test Report Event log. See Table 7 on page 50
and Figure 40 on page 49.

Known Issue: When configured for three-phase trip/three-phase lockout, the MLS voltage readings will show
an observed value of zero for Phase A and C, which is outside of the expected range and below the expected
value, but the status will still show “OK.” This is not indicative of an issue with the control. If an issue outside the
normal range is noted for Phase B, notify S&C Electric Company.
