SETTING PARAMETERES (CONTINUED)
- Single-phase measurement module Cat.No 4 149 18:
In the event of an error in the wiring of the direction of the current
in the Rogowski coil, it can be modified, by intervening only on the
parameters.
Setting parameters on the mini-configurator:
- Three-phase measurement module Cat.No 4 149 22:
In the event of an error in the wiring of the direction of the current
in the Rogowski coil, it can be modified, by intervening only on the
parameters.
Setting parameters on the mini-configurator:
DATA TRANSFER
The measurement modules transfer information directly over the
CX³ EMS bus and can thus be used to transfer data to an operating
system.
As previously seen (“Viewing data” section), the information
is available on the mini-configurator, the touch screen, the
measurement software and the Energy Web Server.
The Modbus register tables are made available for use by a
systemsintegrator.
In this case, an CX³ EMS/RS485 Modbus interface is needed.
ADDRESSING
Addressing can be done:
■ Locally on the product
- addressing from 1 to 9 using a selector.
■ Via software
– addressing from 1 to 247
– the selector then stays on 0.
The load-shedding function is possible with
the integration of the universal control module
Cat.No 4 419 32. Details and examples can be found
in the section «Data sheet, configuration software
CX³ EMS» on page 76.
The specifications for connection to the CX³ EMS bus are
common to all CX³ EMS devices and are described in the
product technical data sheets.
Local setting using the selector takes priority over
software Setting parameters. In the event of
malfuntion, check that the selector is definitely on zero.
