Front-Panel Settings (SET F Command)
Target LED Settings
The SEL-700G offers the following two types of LEDs. See Figure 8.1 and
Figure 8.26 for the programmable LED locations:
➤
Six Target LEDs
➤
Eight Pushbutton LEDs
You can use SEL
OGIC
control equations to program all 14 LEDs. The target
LEDs differ from the other LEDs in that they also include a latch function.
Target LEDs
The settings Tn_LEDL (n = 01 through 06) and Tn_LED (n = 01 through 06)
control the six front-panel LEDs. With Tn_LEDL set to Y, the LEDs latch the
LED state at TRIP assertion. To reset these latched LEDs, the corresponding
LED equation must be deasserted (logical 0) and one of the following takes
place:
➤
Pressing
TARGET RESET
on the front panel.
➤
Issuing the serial port command TAR R.
➤
The assertion of the SEL
OGIC
control equation RSTTRGT.
With the TnLEDL settings set to N, the LEDs do not latch and directly follow
the state of the associated SEL
OGIC
control equation setting.
Enter any of the Relay Word bits (or combinations of Relay Word bits) as
conditions in the Tn_LED SEL
OGIC
control equation settings. When these
Relay Word bits assert, the corresponding LED also asserts.
Table 4.89 shows the target LED settings. The factory-default settings shown
match the as-shipped front-panel overlay (see Figure 8.1). You can change the
settings to suit your application. See Section 8: Front-Panel Operations for
slide-in labels for custom LED designations.

NOTE:
If the LED latch setting
(TnLEDL) is set to Y, and TRIP asserts,
the LED latches to the state at TRIP
assertion. The latched LED targets
can be reset using TARGET RESET if
the target conditions are absent.
