1 Functional description
The FOX-D1, FOX-D1/E is a universal digital display
for the display of the actual battery voltage and the
charge or discharge current.
The pushbutton switch at the front switches the display
from voltage display to current display and vice versa.
The device itself can remain switched on, due to the
low power requirements of the display.
1. Voltage:
The actual battery voltage is displayed. This gives
you information on the charging state of the battery
(see table at the end of the operating instructions).
2. Current:
The actual current flowing is displayed. Depending
on the direction of the current flow, with or without
the sign "-". Current without algebraic sign is charge
current (i.e. flowing into the battery). The "-" sign
shows that discharge current is flowing from the
battery to the consumers.
The significance of the algebraic sign applies only to
instances where the solar modules or consumers have
been wired according to our connection plans. If the
cables in "IN" and "B-" are interchanged the sign
convention is interchanged too.
