Configuration of Wireless Energy Devices
Presentation
Wireless energy devices can be configured through Panel Server webpages.
Configuration Procedure
To configure wireless energy devices follow the procedure in Configuring Wireless Devices Through Webpages.
The following tables list the parameters for the configuration of wireless energy devices.
The fields displayed depend on the type of device.
Parameter Tables
Identification
Refer to Configuring Wireless Devices Through Webpages.
Electrical characteristics
| Parameter name | Description |
|---|---|
|
Phase sequence |
Select from the list to define the phase sequence of the meter depending on the way the physical panel is wired and according to the phase indication printed on the product, for example ACB. |
|
External neutral voltage sensor |
Select the availability from the list:
NOTE: Available for display only,
depending on the power meter.
|
|
Mounting position |
Select the mounting position from the list:
|
|
Current flow |
Select the to define the convention for the energy device to count energies. See the section Current Flow for more information about filling this parameter. |
|
Power factor sign convention |
Select the power factor sign convention form the list. The setting has an influence on the convention used to sign the power factor.
For more information, see the section Power Factor Sign Convention. |
Communication Settings
| Parameter name | Description |
|---|---|
|
Communication period (s) |
When available for the selected wireless device, you can set the communication period at a value different from the value set at family devices level. Select a value of between 2 and 120 seconds from the list (default setting 5 seconds). NOTE: It is possible to set 2 seconds as the communication
period of a device which belongs to the Energy-related wireless devices
family, like Acti9 Active, Acti9 PowerTag, Acti9 Vigi, PowerLogic Tag (PLT).
NOTE: Use a maximum setting
of 90 seconds if power demand calculation is required.

|
Earth leakage pre-alarm threshold |
Select the threshold for the earth-leakage pre-alarm. |
|
Over voltage pre-alarm threshold |
Select the threshold for the over voltage pre-alarm. |
|
Overcurrent pre-alarm threshold |
Select the threshold for the overcurrent pre-alarm. |
Current Flow
For PowerTag Energy devices F160 and Rope, selecting the current flow defines the convention for the PowerTag Energy device to count energies.
The current flow can be Direct or Reverse:
-
Direct: If the arrow marked on the PowerTag Energy device is in the same direction as the current flow.
-
Reverse: If the arrow marked on the PowerTag Energy device is in the opposite direction to the current flow.
Power Factor Sign Convention
The power factor sign convention setting can be one of the following:
-
IEC: In this setting,
-
when active power is negative, the power factor sign is –.
-
when active power is positive, the power factor sign is +.
-
-
IEEE: In this setting,
-
when the load is capacitive, the power factor sign is +.
-
when the load is inductive, the power factor sign is –.
-
The following diagram summarizes the power factor sign convention:
Power Demand Calculation Time Interval
The Panel Server calculates the following values:
-
Active power demand over the specified time interval
-
Peak active power demand value during the specified interval
Set the demand calculation time interval between 1 and 60 minutes at . A pop-up message is displayed if you try to set an invalid value.
You can reset the peak power demand value to 0 for:
-
All PowerTag devices connected to the Panel Server, including PowerTag Rope on the Panel Server webpages at
-
Individual devices at , by clicking on the device name to open the device page and scrolling to Active power demand.
The Panel Server stores the date and time of:
-
Each new maximum (peak) value of active power demand since the last reset
-
Reset of peak active power demand
The power demand value is calculated using arithmetical integration of power RMS values over a period of time, divided by the length of the period. The result is equivalent to the energy accumulated during the period of time divided by the length of the period. The power demand is calculated according to the sliding block method.
At the end of the power demand calculation interval and then every one tenth of the interval, for example, for an interval of 15 minutes, every 1 minute 30 seconds:
-
The demand value over the interval is calculated and updated.
-
Calculation of a new demand value is initialized on a new interval:
-
By eliminating the contribution of the first tenth of the previous interval
-
By adding the contribution of the latest tenth
