STATUS R or C (Level 2)
To reset the self-test status and restart the relay, enter the STA R command from
Access Level 2.
The relay then restarts (like powering down and then powering up the relay) and
all diagnostics are rerun before the relay is enabled.
STOP (Level 2)
The STOP command causes the relay to trip, opening the motor contactor or
circuit breaker and stopping the motor. For more details refer to Chapter 6:
Configuring Protection & Logic Functions.
STR (Level 2)
The STR (START) command initiates a motor start using the relay's internal
logic. For more details refer to Chapter 6: Configuring Protection & Logic
Functions.
SUMMARY (Level 1 or 2)
The SUM n command displays a summary list, in reverse chronological order, of
all the archived event summary reports (maximum of five events).
An example event summary report is in Figure 61. Each event summary report
shows the date, time, current magnitudes (primary values) and, if the relay has the
voltage option, voltage magnitudes (primary values). The current and voltage
values are at the trigger instant. The event summary report also shows the event
type (e.g., OVERLOAD TRIP).
The
n parameter with the SUM n command can have a value up to 5 and defines
the number of events requested. If
n is not specified, then up to five of the most
recent reports are listed.
For more information on events, refer to Chapter 8
, Analyzing Events.
