6.1 Device interface
6.1.1 Displays and operator controls
The following display and control elements (illustration shows the PAC3220, but the
PAC3120 also has the same elements) are on the front panel of the power monitoring
devices.
①
Display area:
Displays the current measured values, device settings and selection menus.
②
Header area:
Specifies the information visible in the display area.
③
Multi-colored LED:
Works like a normal digital output. The functions and color can be configured by the user.
④
Footer area:
Specifies the functions assigned to the function keys.
⑤
Surfaces of the function keys:
The keys have multiple assignments. Function assignments and key labeling change according
to the context of operator input. The designation of the current key function can be seen above
the key number in the footer area of the display.
A short press on the key triggers the function once. Holding the key down for longer switches
on the autorepeat function after approximately 1 s. The function of the key is triggered repeat-
edly while the key is held down. Autorepeat is useful, for example, for fast incrementing of
values when parameterizing the device.
