SEL-352-1, -2 Instruction Manual
Note: Make Sequential Events Recorder (SER) Settings With Care
The relay triggers a row in the Sequential Events Recorder (SER) event report for any change of
state in any one of the elements listed in the SER1, SER2, or SER3 trigger settings. Nonvolatile
memory is used to store the latest 512 rows of the SER event report so they can be retained
during power loss. The nonvolatile memory is rated for a finite number of “writes.” Exceeding
the limit can result in an EEPROM self-test failure. An average of 1 state change every 3
minutes can be made for a 25-year relay service life.
SET T (Edit Display Text Settings)
Access Level 2
Configure the front-panel Local Bit and Display Point settings using the SET T command. The
Local Bit settings are NLBn (function name label), CLBn (“clear bit” label), SLBn (“set bit”
label), and PLBn (“pulse bit” label). The Display Point settings are DPn_1 and DPn_0, the text
displays for the two logic states of variable DPn. (Note: the DPn variables are set using the
standard SET command.) See Section 9: Front-Panel Interface for more information on these
settings. The entire syntax of the SET T command follows:
SET T setting TERSE<ENTER>
The two parameters are optional and perform the following functions:
 setting specifies the setting name to immediately jump to. The default is the first setting.
 TERSE disables the display of the new settings at the end of the setting procedure.
The SET T procedure works just like the SET procedure. Table 8.4 lists the editing keys that
you can use with the SET command.
Refer to the SHO T command for a list of the factory default settings. Refer to Section 7:
Setting the Relay for all default settings and settings worksheets.
SHO (Show Settings)
Access Level 1
SHOWSET displays the relay settings of the currently selected group. The entire syntax of the
SHO command follows:
SHO n setting A<ENTER>
 n specifies the setting group (1, 2, or 3). The default is the active setting group.
 setting specifies the setting name to immediately jump to. The default is the first setting.
 If setting = A, then hidden settings are shown in addition to the regular settings.
Control characters provide control over the scrolling of the data:
Temporarily Stop Scrolling: <CTRL>Q (hold down the Control key and press Q)
Restart Scrolling: <CTRL>S (hold down the Control key and press S)
Cancel Scrolling Completely: <CTRL>X (hold down the Control key and press X)
