Current transformer (Addr. 600)
Either 1A or 5A transformers secondaries can
be connected to UMG96S optionally.
When the device is delivered, a CT of 5A/5A is
programmed. In programming mode, the current
transformer is shown by the symbol „
CT
“.

Example: Sum current transformer
A current measurement is carried out via one
transformer with a ration of 1000/5A and one
current transformer with a ratio of 1000/5A. The
sum measurement is carried out by a sum cur-
rent transformer 5+5/5A.
The UMG96S must be programmed as follows:
Primary: 1000A + 1000A =
2000A
Secondary:
5A
CT, primary(600)
Programming
In programming mode, please scroll to the set-
ting of current transformer with key 2. Confirm
with key 1.
The first number of the primary is flashing and
can be changed with key 2. Confirming with key
1, the next number is selected and flashes.
If the complete number is flashing, the decimal
point can be moved.
Pressing key 2 shortly, the decimal point moves
to the right.
Pressing key 2 for a long time, the decimal point
moves to the left.
If no number is flashing, scroll to the indication of
the voltage transformer with key 2.
