5. Confirm with key 1 - the first number of the
parameter address flashes.
6. Using key 2, select the value for the 1st
number.
7. Continue the procedure for the next numbers
of the parameter address and for the
parameter settings.
8. Exit programming mode by simultaneously
pressing key 1 and 2 (1 s). Switch back to the
input area for the current transformer using
key 2.
NOTE
·The parameter addresses for the device
address (000) and the baud rate (001) are
explained next.
·A parameter list with the most important
setting ranges and default settings can be
found in chap. „18.2 Parameter and Modbus
address list“ on page 62 or the Modbus
address list on our web site.
12.7.1 Setting the device address
(parameter address 000)
A master device can distinguish the UMGs
based on the device address in a master/slave
network via the RS485 interface.
For devices within this network, ensure
the following:
·different device addresses are assigned.
·the device address is within the range
of 1 to 247 (0 and 248 to 255 are reserved).
12.7.2 Setting the baud rate
(parameter address 001)
For each device in a master/slave network via
the RS485 interface:
·select a
consistent
baud rate (parameter
address 001) (0= 9.6 kbps, 1=19.2 kbps,
2=38.4 kbps).
·select the number of stop bits (parameter
address 002) (0=1 bit, 1=2 bits, 2=1 bit even
parity, 3=1 bit odd parity).
Data bits (8) are fixed.

12.7.3 Mean values and averaging times
(parameter address 040, 041 and 042)
To establish mean values for the current, power
and voltage measured values, the device
requires averaging times.
The device
·identifies mean values in the display with
a slash above the measured value.
·offers 9 settings, for the
-
current averaging time (address 040),
-
power averaging time (address 041) and
-
voltage averaging time (address 042).
In the parameter addresses, the settings listed
correspond to the following averaging times:
