10. Module-relevant configurations
10.1 LP current transformer configuration on the
basic device
In this user manual, the term "current transformer"
is used for special transformers for the proportional
conversion of currents of large amperages to directly
measurable, smaller
current values . In contrast, the
term "LP current transformer" is used for spe-
cial transformers for the proportional conversion of
currents of large amperage to directly measurable,
smaller
voltage values (800-CT24 modules).
Current transformers and current sensors provide a
safe galvanic isolation between the primary circuit
and the measurement circuit due to their construc-
tive design and their physical operating principle.
For simplification, the UMG 801 basic device only
uses the term "current transformer" in the display to
configure both "current transformers" and "current
sensors".

confirm with button 3 Enter .
·The item Basic device appears marked in "blue."
·Use buttons 2 "

the module, e.g. Module 1 and confirm with button
3 Enter .
·Use button 5 "

" to go to the setting for the pri-
mary side of the LP current transformers 1-4 of the
module (current measurement inputs I1..I4).
·The item for the primary side of the LP current
transformers I1..I4 appears marked in "blue."
·Press button 3 Enter.
·The item for the primary side of the LP current
transformers I1..I4 "blinks".
·Use buttons 4 (

) and 6 (

) to change the position
of the digit to be set and buttons 2 (
5
) and 5 (
6
) to
change the digit (-1/+1).
·Confirm your entries with button 3 Enter or end the
action by pressing button 1 ESC .
·Use button 6 (

) to go to the configuration of the
secondary side of the LP current transformers I1..I4
of the module.
·Configure the secondary side of the LP current
transformers I1..I4 of the module in the same way
(note here the "nominal voltage in mV" for the LP
current transformers).

INFORMATION
Before configuring the LP current transformer ratios,
be certain to connect the transformers in compliance
with the specifications on the device rating plate and
the technical data!
