SEL-487V Data Sheet Schweitzer Engineering Laboratories, Inc.
10
Close-up views of the front panel of the SEL-487V are
shown in Figure 8, Figure 9, and Figure 10. The front
panel includes a 128 pixel by 128 pixel, 3 in. by 3 in.
LCD screen, LED target indicators, and pushbuttons with
indicating LEDs for local control functions. The asserted
and deasserted colors for the LEDs are programmable.
Configure any of the direct-acting pushbuttons to
navigate directly to an HMI menu item, such as events,
bay display, alarm points, display points, or the SER.
Status and Trip Target LEDs
The SEL-487V includes programmable status and trip
target LEDs, as well as programmable direct-action
control pushbuttons/LEDs on the front panel. These
targets are shown in Figure 8 and Figure 10 and are
explained in Table 4.
The SEL-487V features a versatile front panel that you
can customize to fit your needs. SEL
OGIC control
equations and slide-in configurable front-panel labels
change the function and identification of target LEDs
and operator control pushbuttons and LEDs. The blank
slide-in label set is included with the SEL-487V. Label
sets can be printed from a laser printer using templates
supplied with the relay or hand labeled on supplied blank
labels.

Advanced Display Points
Create custom screens showing metering values, special
text messages, or a mix of analog and status information.
Figure 11 shows an example of how display points can
be used to show circuit breaker information and current
metering. As many as 96 display points can be created.
All display points occupy only one line on the display at
all times. The height of the line is programmable as
either single or double (see Figure 11). These screens
become part of the autoscrolling display when the front
panel times out.
