Jumper Settings
By jumper a common reference can be made between the invol-
ved channels of a group (see diagram 13).
For the
output channels
a common ground can be defined for
each group (KL1 resp. KL2). For every channel, which should be
refered to it, the corresponding jumper JP
x
must be set. By the
clamps KL1.1 resp. KL2.1 the ground reference for each group
must be done. For example: if the jumpers JP1 and JP4 are set
you can connect the ground reference of group KL1 to the clamp
KL1.1.
The
input channels
can be refered alternatively to a positive
reference voltage or to a common ground. For every channel,
which should be refered to a positive reference, the correspon-
ding jumper JP
x
a must be set. For every channel, which should
be refered to ground, the corresponding jumper JP
x
b must be set.
For example: if the jumpers JP13b and JP16b are set you can con-
nect the ground reference of group KL4 to the clamps KL4.2 or
KL4.8.
Please note
, out of each pair of jumpers JP
x
a,b only one jumper
may be set!

If required, the grounds of group KL1 and KL2 (JP17) can be con-
nected. Additionally the positive references (JP18a) or the
ground references (JP18b) of KL3 and KL4 can be connected with
each another.
