Front-Panel Operations
Operation and Target LEDs
Target LEDs
Settings Tn_LEDL (n = 00 through 06) and Tn_LED (n = 00 through 06) control
the seven front-panel LEDs. With Tn_LEDL set to Y, the LEDs latch after asser-
tion. To reset these latched LEDs, the corresponding LED equation must be deas-
serted (logical 0) and one of the following takes place:
1. Pressing TARGET RESET on the front panel.
2. Issuing the serial port command TAR R.
3. The assertion of the SEL
OGIC equation RSTTRGT.
With TnLEDL settings set to N, the LEDs do not latch and directly follow the
state of the associated SEL
OGIC control equation (SV) setting.
Enter any of the Device Word bits (or combinations of Device Word bits) as con-
ditions in the Tn_LED SEL
OGIC control equation (SV) settings. When these
Device Word bits assert, the corresponding LED also asserts.
Pushbutton LEDs
NOTE: The lower pushbutton LEDs
are only operable with firmware
version R20x or later.
Enter any of the Device Word bits (or combinations of Device Word bits) as con-
ditions in the PBp_LED (p = 01 through 04B. B LEDs do not use the underscore)
SEL
OGIC control equation (SV) settings. When these Device Word bits assert, the
corresponding LED also asserts. Figure 8.9 shows the setting prompts, setting
ranges, and default settings.
TARGET RESET
Pushbutton
TARGET RESET
Use the TARGET RESET pushbutton to reset latched target LEDs. When a new event
occurs and the previously latched trip targets have not been reset, the device
clears the latched targets and displays the new targets. Pressing and holding the
TARGET RESET pushbutton illuminates all the LEDs. Upon release of the TARGET
RESET pushbutton, two possible situations can exist: the conditions that caused the
LED to illuminate have cleared or the conditions remain present at the device
inputs. If the conditions have cleared, the latched target LEDs turn off. If the con-
ditions remain, the device re-illuminates the corresponding target LEDs.
