6.8.37 STATUS R
(Level 2)
To reset the self-test status and restart the relay,
use the STA R command from Access Level 2.
The relay then restarts (just like powering down,
then powering up the relay) and all diagnostics
are rerun before the relay is enabled.
6.8.38 STOP
(Level 2)
The STOP command causes the relay to trip,
opening the motor contactor or circuit breaker
and stopping the motor. The command also
triggers an event report.
6.8.39 STR
(Level 2)
The STR (Start) command initiates a motor start
using the relay’s internal logic. The factory default
logic configures output contact OUT3 too close to
start the motor. Refer to Section B.5, page 144
for information on changing the factory default
logic.
6.8.40 TARGET
(Level 1 or 2)
The TARGET command displays the status of
relay elements whether they are asserted or
deasserted. The elements are represented as
Relay Word bits and are listed in rows of eight,
called Relay Word rows. For additional
information, refer to Section B.3, page 138.
A Relay Word bit is either at a logical 1 (asserted)
or a logical 0 (deasserted).
The TAR command options are listed in
Table 6.17.

Commands Descriptions
TAR n k Shows Relay Word row number n (0 – 11). k is an optional parameter to specify the number of times (1 – 32767)
to repeat the Relay Word row display. If k is not specified, the Relay Word row is displayed once. SeeTable 6.18
for definition of Row 0. See Table 6.19 for a list of the Relay Word bits in each row (n = 1 – 10).
TAR name k Shows Relay Word row containing Relay Word bit name (e.g., TAR 50P1T displays Relay Word Row 3). Valid
names are shown in Table 6.18. k is an optional parameter to specify the number of times (1 – 32767) to repeat
the Relay Word row display. If k is not specified, the Relay Word row is displayed once.
