Selection and setting of LED

As shown in Figure 12.1-1, the IED provides 26 LEDs and 7 function-keys. The user can

configure LEDs ("LED#3" to "LED#26") and the function key LEDs (F1 to F7; each has a LED).

Each LED is driven via a logic gate which can be programed to be an AND gate, OR gate or

XOR gate operation. Furthermore, each LED has a programmable reset characteristic, settable

for instantaneous drop-off, or for latching operation. One or up to eight signals can be assigned

to a single LED with selectable LED color.

Selection of LED: Figure 12.6-11 shows the LED selection screen; the user

can select a setting item by pressing keys ▲ and ▼. Press key ► to go to the

next level in the hierarchy.
