6.3.4 Internal setpoint specification
If the internal setpoint is selected (factory setting), it is possible to
select one of 4 internal setpoints via terminals X12:1-4. To do this,
either X12:1 and X12:2 or X12:3 and X12:4 must be bridged (see table
below). Potentiometers R14, R15, R16 and R17 can then be used to
set the setpoints for trickle charging (default setting; all terminals open),
heavy charging, mains backup system and manual charging. The
procedure is to be carried out according to 6.2.5 for the respective
voltages, whereby the voltage must be selected via the terminals.
The output voltage monitors can only be set once and the same for all
voltage values.
The desired voltage setpoint is set using the following table:

6.3.5 Actual value output
The actual values can be displayed via the connections
- X12:7 (actual voltage value) and X12:8 (actual ground value)
- X12:9 (actual current value) and X12:10 (actual ground value)
can be tapped.
A 0-20 mA signal is present as standard. When jumper X12:5 - X12-6
is closed, a 0-10 V signal is output (via an internal 500 Ω load).
A quiescent current or voltage offset is not possible.
Any external supply to the connections of the actual value output is not
permitted.
The actual value output is at the same potential as external on/off and
the setpoint switchover.
Information on scaling, tolerance and measuring range: see
section 4.
