Front-Panel Overview
You can use the following features of the versatile front panel to customize it
to your needs:
➤
Rotating display on the HMI
➤
Programmable target LEDs
➤
Programmable pushbutton LEDs
➤
Slide-in configurable front-panel labels to change the
identification of target LEDs, pushbuttons, pushbutton LEDs
and their operation.
Human-Machine Interface
Contrast
You can adjust the LCD screen contrast to suit your viewing angle and
lighting conditions. To change screen contrast, press and hold the
ESC
pushbutton for two seconds. The SEL-700G displays a contrast adjustment
box. Pressing the
Right Arrow
pushbutton increases the contrast. Pressing the
Left Arrow
pushbutton decreases the screen contrast. When you are finished
adjusting the screen contrast, press the
ENT
pushbutton; this process is a
shortcut for changing the LCD contrast setting FP_CONT in the front-panel
settings.
Front-Panel
Automatic Messages
The relay displays automatic messages that override the rotating display under
the conditions described in Table 8.1. Relay failure has the highest priority,
followed by trip and alarm when the front-panel setting
FP_AUTO := OVERRIDE.
If the front-panel setting FP_AUTO := ROTATING, then the rotating display
messages continue and any TRIP or ALARM message is added to the rotation.
Relay failure still overrides the rotating display.
