Commissioning of the temperature or voltage measurement
For simple commissioning of the EL331x-xxxx, the thermocouple or the voltage to be measured must first be connected to the terminal in the 2-wire connection configuration. The connection of the terminals can be found in the specific chapter "Connection" under the selected product in the Product overview.
The basic setting for a channel of the EL3314 is shown here as an example. The procedure is the same for all EL331x-xxxx terminals. It differs only in the selectable measuring ranges and the number of channels for which these settings must be made.
All channel-specific settings are located in the CoE object 0x80n0, where n+1 specifies the number of the channel to be parameterized.
For simple commissioning, it is only necessary to specify the thermocouple type or the measuring range.
- 1. For simple commissioning with the use of the internal cold junction measurement, make sure that the value "internal (0)" is selected in the object 0x80n0:0C "Cold junction compensation" (see Fig. "Setting the measuring range", A).
- 2. To specify the type of thermocouple or the voltage measuring range, the object 0x80n0:19 TC element must be opened with a double click (see fig. "Setting the measuring range", B). There, in the dropdown list (see fig. "Setting the measuring range", C), you can choose between all possible ranges. This setting must then be made specifically for each wired channel.
- 3. The measurement can then be started and the measured value is displayed in the process data in the preset display.
Further possibilities for parameterization of the individual channels are described in the chapter Settings.
