Acuvim II Analog Output Settings

Detailed configuration walkthrough for the Acuvim II for analog output.

Note: The Analog Output can only be activated through the display of the meter, to configure the range of the output you must use the AcuView software. Otherwise the meter will use the default input range.

Activating Analog Output
Make sure you are on the ‘Setting’ mode. To get to this screen, press ‘H’ and ‘V/A’ simultaneously; the display selection mode will be activated and the screen should become blank. With the cursor flashing, press ‘P’ or ‘E’ to move the cursor to ‘Setting’. Press ‘V/A’ to enter the ‘Setting’ mode.

Figure 1: Parameter Selection Mode

  • The cursor will be on 'SYS'. Press 'P' on this screen to move the cursor to the 'I/O' settings. Press 'V/A' to enter.

In the I/O parameter mode, you can choose the available modules attached to the meter. To do this, you can press:

  • 'H' to return to the parameter selection mode
  • 'P' to move the cursor downward and 'E' to move the cursor upward
  • ‘V/A’ to select the module; this will enter the setting page for the I/O module that was selected.

Figure 2: Analog Selection Page

Note: M11 represents AXM-IO1-1 while M31 represents AXM-IO3-1. For IO2 module select 'M21'

  • Press 'P' to get to the 'AO MODE' screen.

Set the AO Mode according to the module option. That is, you can only set the AO mode as 0-20mA or 4-20mA if you have the 'Current mA' AO option. If you have the 'Voltage V' AO option, then you can set the AO mode as 0-5V or 1-5V.

Figure 3: Module Selection Page

0: Represents 0-20mA, 1: Represents 4-20mA, 2: Represents 0-5V and 3: Represents 1-5V.
  • Press 'P' to move to the 'AO1 SEL' screen.
    • Select the parameter you will like to output through the AO1 channel.
  • Press 'P' to move to the 'AO2 SEL' screen.
    • Select the parameter you will like to output through the AO2 channel.

The table below shows the 'AO1 SEL' and 'AO2 SEL' setting values and their corresponding parameters.
Setting Value Transducer Parameter Setting Value Transducer Parameter Setting Value Transducer Parameter
0 Frequency 1 Va 2 Vb
3 Vc 4 Average Phase Voltage 5 Vab
6 Vbc 7 Vca 8 Average Line Voltage
9 Phase A Current 10 Phase B Current 11 Phase C Current
12 Average Current 13 Neutral Current 14 Phase A Real Power
15 Phase B Real Power 16 Phase C Real Power 17 Total Real Power
18 Phase A Reactive Power 19 Phase B Reactive Power 20 Phase C Reactive Power
21 Total Reactive Power 22 Phase A Apparent Power 23 Phase B Apparent Power
24 Total Apparent Power 25 Total Apparent Power 26 Phase A PF
27 Phase B PF 28 Phase C PF 29 Total PF
By default the input range for the selected parameter used for Analog Output will be up to the maximum value for that parameter.
Parameter Default Input Range
Frequency 45 - 65 Hz
Volts An, Bn, Cn, Ln average 0 - 480 V
Volts AB, BC, AC LL average 0 - 831 V
Pwr Factor A, B, C, Total -1 - 1

When using any of the three phase currents as the parameter to output, the following maximum value for that parameter is determined by the CT1 and CT2 settings.

Note: For meters with RCT, 333mV and mA current input take CT2 as 1.
Current Input of Meter (CT2) Default Input Range
5A 0- (CT1*10)/CT2 A
1A 0- (CT1*10)/CT2 A
333mV 0- CT1/(CT2*10) A
RCT 0- CT1/(CT2*10) A
80/100/200mA 0- CT1/(CT2*10) A
When using the power parameters, the default input range value will be -|Max|, where the Max value can be obtained as:
Power Parameter Default Input Range
Watt A, B, C (kW) -(V*I) -(V*I)
Watt Total (kW) -3(V*I) - (3*(V*I))
VAR A, B, C (kW) -(V*I) - (V*I)
VAR Total (kW) -3(V*I) - (3*(V*I))
VA A, B, C (kW) 0- (V*I)
VA Total (kW) 0- 3*(V*I)
Note: By default 'V' will be 480 and 'I' will be the high end of the input range determined by the current input of the Acuvim II meter. For setting the Analog Output through the AcuView software please refer to "How To: Configure AcuView Software for use with Acuvim II" and reference the "Analog Output (AO)" section.
