Function Definition
➀
PUSHBUTTONS
Except for
TARGET RESET
/
LAMP TEST
, the pushbuttons have dual functions (primary/secondary).
After you select a primary function (i.e.,
METER
pushbutton), the pushbuttons operate on their
secondary functions (
CANCEL
,
SELECT
, left/right arrows, up/down arrows,
EXIT
) so you can scroll
through information, activate settings/control, etc., on the LCD.
➁
CONTROL ENABLED
a
a
These indicated LEDs and the operator control have fixed functions. Programming at a higher logic level can change functions of all other LEDs
and operator controls (with corresponding status LEDs).
SEL-351R Falcon Recloser Control is enabled.
AC SUPPLY
Adequate Vac power is present.
BATTERY PROBLEM
Indicates battery problems.
HOT LINE TAG
No closing or autoreclosing can take place via the control.
TRIP Trip occurred.
FAST CURVE
Fast curve overcurrent element trip.
HIGH CURRENT
High-set overcurrent element trip.
81
Underfrequency trip.
RESET The control is in the reset state, ready for a reclose cycle.
CYCLE
The control is actively in the trip/reclose cycle mode.
LOCKOUT
All reclose attempts were unsuccessful.
A
,
B
,
C
a
A-, B-, or C-phase involved in fault.
G Ground involved in fault.
SEF
Sensitive earth fault overcurrent element trip.
➂
GROUND ENABLED
Enables/disables ground overcurrent elements.
RECLOSE ENABLED
Enables/disables autoreclosing.
REMOTE ENABLED Enables/disables remote control.
ALTERNATE SETTINGS
Switches active setting group between main and alternate setting groups.
LOCK
(press for 3 seconds) Blocks the function of other operator controls (except
WAKE UP
and
TRIP
). Three-second delay to
engage/disengage.
AUX 1
User programmable; e.g., program to Trip Test—test autoreclose logic without applying current.
AUX 2 User programmable; e.g., program to enable/disable fast-curve tripping.
WAKE UP
a
Wakes up the control after it has been put to sleep.
CLOSE
/
RECLOSER CLOSED
Close recloser/recloser closed status.
b
b
You can set the CLOSE operator control with a delay, which allows an operator to press CLOSE and then move a safe distance away from the recloser
before closing proceeds.
TRIP
/
RECLOSER OPEN
Trip recloser (go to lockout)/recloser open status.
c
c
You can set the TRIP operator control with a delay, which allows an operator to press TRIP and then move a safe distance away from the recloser
