Description

 

 

RMS Measure

This tab provides power, current, and voltage values as well as frequency and power factor information.

 

 

 

 

 

 

Meter Status

This tab provides information on the settings and status of the digital input, digital outputs and alarms as

 

 

well as existing power system settings.

 

 

 

 

Configuring the meter using the M-Bus tool

1.Select Setup > Config to switch to configuration mode.

2.Set the values that you want to change then click Send for that value or section. For example, to change the nominal frequency, select a different value from the list then click Send in Set Wiring.

Some values may be unavailable based on existing settings.

NOTE: If Com. Protection is enabled, you may receive a message that the configuration failed.

Use the HMI to either: 1) configure the meter, or 2) disable Com. Protection then configure the meter using the tool.

The configuration screen has the following sections:

Section

Description

Set Wiring

Configure power system settings (for example, power system configuration and nominal

frequency).

 

Set Digital Input

Set the digital input mode and pulse constant.

 

 

Set Digital Output

Enable / disable the digital output and set the control mode, pulse weight and duration.

 

 

Set Multi Tariff

Disable the Multi Tariff feature or set the control mode to by Communication and set the active tariff

if the control mode is set to by Communication.

 

Set Power Alarm

Enable / disable to the overload alarm, enter the setpoint, and acknowledge alarms.

 

 

Reset

Reset partial energy and input metering accumulations.

 

 

Set Date Time

Set the date and time or send a time synchronization signal to set the meter to the computer time.

 

 

Set Baudrate

Set the baud rate.

 

 

Set Address

Set the meter address.
