Caption to the front of the PR112 unit :
Alphanumerical display of the LCD type with 4 lines with 20 characters each, and which is rear-lit when auxiliary voltage is present. It is possible
to adjust the contrast.
Each time the unit is activated, the display indicates the following page:
CURRENT
L1:xxxxxA
L2:xxxxxA
L3:xxxxxA
Ne:xxxxxA
(*) Ground:xxxxxA
(*) Indication only displayed in the case of PR112 unit/LSIG trip.
The “……A” indication corresponds to a current reading under the measurable minimum (0.1In).
The “—— A” indication corresponds to disabling of current measurement (ground fault).
Any “alarm” or “error” messages are displayed on the first line of this page. When there are more than one of these, they are displayed cyclically,
one each second, on the first line. By pressing the
↵
key, it is possible to block message scrolling at the one currently displayed (the symbol
“
←
” appears in the right-hand corner of the line). The various messages can therefore be scrolled through one at a time by using the “
↓
” key.
To reset automatic updating, press the
↵
key again (the symbol “
←
” disappears).
