Programming parameters
Switching to programming mode
• Switch to the programming mode as described. The symbols for
the programming mode (PRG) and for the current transformer
(CT) appear.
• Use button 2 to switch to the voltage transformer setting. The
rst parameter of the parameter list is shown by repeatedly
pressing button 2.
Changing parameters
• Conrm the selection with button 1.
• The most recently selected address is displayed with the as-
sociated value.
• The rst digit of the address ashes and can be changed using
button 2. Button 1 provides a selection of digits that, in turn, can
be changed with button 2.
Changing the value
• Once the desired address is set, a digit of the value is selected
with button 1 and changed with button 2.
Leaving programming mode
• Simultaneously press buttons 1 and 2 to exit the programming
mode.

If a password was set, it can be entered using buttons 1
and 2.
Fig.: Current transformer programming mode:
The primary and secondary currents can be changed using
buttons 1 and 2.
Fig.: Programming mode voltage transformer:
The primary and secondary currents can be changed using
buttons 1 and 2.

The individual parameters can be changed using buttons 1
and 2.
Device address (addr. 000)
If several devices are connected to one another via the RS485
interface, a master device can only differentiate between these de-
vices by means of their device addresses. Therefore, each device
in a network must have a different device address. Addresses can
be set in the range from 1 to 247.
The adjustable range of the device address is between
0 and 255. The values 0 and 248 to 255 are reserved
and may not be used.
Baud rate (addr. 001)
A common baud rate is adjustable for the RS485 interfaces. The
baud rate must be chosen to be a uniform value in the network.
On address 003 the quantity of stop bits can be set (0 = 1 bit,
1 = 2 bits). Data bits (8) are permanently set.
Setting Baud rate
0 9.6 kbps
1 19.2 kbps
2 38.4 kbps
3 57.6 kbps
4 115.2 kbps (factory setting)
