Opening The Case - Relay AnDi1 User Manual

Each input channel of the AnDi4 has to be configured either to current or voltage measurement
by setting up two jumpers on the measuring module. The factory setup is current mode for all
channels. The housing of the AnDi4 must be opened to change the jumper settings (see picture
6).
Picture 5 shows the different jumper positions
current and voltage mode: Please take care that
jumpers are placed exactly according to the
drawing. The galvanic insulation between M-
and A/D converter requires the use of two
jumpers to select the measuring mode. The
jumper down on the right gives information
about the mode to the microcontroller and the
jumper in the center left configures the input of
channel.
