To simplify your review of the information displayed in the SER record, the relay
provides the Alias setting function. Using the Alias settings, you can change the way
relay elements listed in the SER settings above are displayed in the SER report. In
addition, the Alias settings allow you to change the text displayed when a particular
element is asserted and deasserted. The relay permits up to 20 unique aliases, as
defined by the Enable Alias Settings (EALIAS) setting. Factory default alias settings
are shown in Table 4.43.
Define the enabled alias settings by entering the Relay Word bit name, a space, the
desired alias, a space, the text to display when the condition asserts, a space, and the
text to display when the condition deasserts.
ALIAS1 = STARTING MOTOR_STARTING BEGINS ENDS
See Relay Word Bits in Appendix B: Relay Word Bits on page B.4 for the complete
list of Relay Word bits. Use up to 15 characters to define the alias, asserted text, and
deasserted text strings. You can use capital letters (A–Z), numbers (0–9), and the
underscore character (_) within each string. Do not attempt to use a space within a
string because the relay will interpret a space as the break between two strings. If you
wish to clear a string, simply type ‘NA’.

START
Motor Start.
Asserts when an internal relay function calls for a
motor start. A motor start will only occur if a relay output contact
is programmed and connected to close the contactor or motor
circuit breaker.
50P1T, 50P2T
Phase Fault.
Assert when the relay issues a phase fault trip due to
pickup and timeout of a phase definite-time overcurrent element.
