4.1.2 Signal terminals configuration
The jumpers on the control board are for the
configuration of the analogue- & digital-
inputs as well as the serial RS485 channel.
The placement and default settings of the
jumpers are seen in Fig. 2 and explanations
about their use are described in the following
sections.

4.1.3 Analogue current input
To use analogue current input 1, move J701
to “I” position. If more than one unit is
controlled by a single current input signal,
then J702 should be removed or moved to
position “X”. This allows the common-mode
voltage to vary by ±24V from 0V
The same applies for J703 and J704 when
using analogue current input 2.
Input resistance: 82
Ω
.
Note: When used as voltage inputs, J702 and
J704
must
be mounted in “0” position.
