SEL-387E Instruction Manual
output contact is being pulsed, all other output contacts are frozen in their existing states
and are not permitted to change. This could prevent a trip or other critical output from
being issued during the specified PUL time interval.

QUI (Quit)
Access Levels 0, 1, B, 2
The QUI command returns the relay to Access Level 0 from Level 1, B, or 2. The command
displays the relay settings RID, TID, date, and time of QUI command execution.
Use the QUI command when you finish communicating with the relay, to prevent unauthorized
access. The relay automatically returns to Access Level 0 after a certain inactivity time
dependent on the SET P setting T_OUT.

RES (RESET51—Reset Inverse-Time O/C Elements)
Access Level 2
The RES command clears the inverse-time overcurrent element accumulators (phase, negative-
sequence, and residual) for all three windings. It also clears the combined overcurrent phase and
residual inverse-time elements. This command is useful in testing the inverse-time elements,
because it mimics the action of immediately returning an electromechanical disk to the starting
position. This command can save time in waiting for some units to reset according to their
electromechanical reset equations in Section 3: Protection Functions.
The relay will ask “Reset 51 Elements (Y/N) ?” when given the RES command. If No, it will
abort the command. If Yes, it will respond “All Time-Overcurrent Element Accumulators
Cleared.” This command is not likely to have much use in normal in-service relay operation.
SER (Sequential Events Recorder)
Access Levels 1, B, 2
The SER command displays the last 512 sequential events records. To limit the number of
records displayed, use number or date parameters with the SER command. SER d1 shows only
events triggered on the date specified by d1. SER d1 d2 shows only events triggered on or
between the specified dates. SER m shows the most recent m events. SER m n shows event
