S&C Instruction Sheet 695-535 41
Viewing Event Logs
Event Category Legend:
OK = Operating within normal parameters
ERROR = Operating outside of normal parameters (The control requires immediate
servicing. Contact your local S&C Sales Ofce.)
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 Office 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.)

Figure 30. A Control Self-Test Report.
● 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.
NOTICE
If a control error is registered on the Control Self-Test Report, notify S&C Electric
Company. A control in an error state may not operate as expected.
