AXM-IO1 (M11 or M12)

Digital Input (DI):

Digital Input (DI) can be used for pulse counting or for switch status monitoring:

  • Setting the pulse counter enable screen to “0” means DI will be used for status monitoring while setting it to “1” means it will be used for pulse counting.
  • On the pulse counter enable “IO CNTR ENBL” screen: 000001 means DI6 to DI2 are status monitors while DI1 is a pulse counter.

Figure 9: DI Mode Configuration

  • On the Pulse Constant “IO CNTR CONT” screen: If DI is a pulse counter, set the pulse constant on this screen. When the number of pulses counted by the DI equals to the pulse constant, the pulse counter number will increase by one.

Relay Output (RO):

Relay Output (RO) can be used as a control output or alarm output.

On the Relay Output mode ’RO MODE’ Screen:

  • Select the output mode for your relay output i.e. either control “CTRL” or alarm output “ALM”.

Note: Control output is to manually switch on the relay, while alarm output is to trigger the relay output through an alarm event.

On the “RO OUT” Screen:

  • When the Relay is set as a control output, you can choose between two control methods i.e. Latch mode “LATCH” or Pulse mode “PUL”.

Note: Latch mode is to manually turn on and off the relay, while Pulse mode is used to turn on the relay for a set number of seconds before it goes back off.

Figure 10: RO Mode Configuration

On the Relay Output Pulse Width “RO PUL WIDH” screen:

  • If the Pulse mode is selected as the relay control method, then the Pulse width would have to be set. This is the time the relay will stay on after it has been manually triggered. The range is 50-3000ms.

AXM-IO2 (M21 or M22)

Digital Input (DI)

Digital Input (DI) can be used for pulse counting or for switch status monitoring:

  • Setting the pulse counter enable screen to “0” means DI will be used for status monitoring while setting it to “1” means it will be used for pulse counting.
  • On the pulse counter enable “IO CNTR ENBL” screen: 0001 means DI4 to DI2 are status monitors while DI1 is a pulse counter.

Figure 11: IO2 DI Mode Configuration

  • On the Pulse Constant “IO CNTR CONT” screen: If DI is a pulse counter, set the pulse constant on this screen. When the number of pulses counted by the DI equals to the pulse constant, the pulse counter number will increase by one.

Digital Output (DO)

Digital Output (DO) can be used either as an alarm output or as an energy pulse output.

On the “DO MODE” screen:
  • Select “PUL” for the digital output to send out energy pulses or select “ALM” for the digital output to send out digital signals during an alarm event.

Figure 12: DO Mode Configuration

On the DO pulse width “DO PUL WIDH” Screen:

  • Put in the pulse width for the digital output if DO is used as an energy pulse output. The range is 20-1000ms.

On the “DO PUL 1” Screen:

  • Select the output energy type for DO1. Range from 0-4. I.e. Import active energy, export active energy etc.

On the “DO PUL 2” Screen:

  • Select the output energy type for DO2. Range from 0-4. I.e. Import active energy, export active energy etc.

0: Represents No Output, 1: Represents Import active energy, 2: Represents export active energy, 3: Represents import reactive energy and 4 Represents export reactive energy.

You will also need to set the DO Energy Pulse Constant. This can be set in the System Setting “SYS” screen. On the SYS page:
  • Go to “S10 PUL CONT P” and set the pulse constant (Pulse/kWh) based on the calculation below
  • Go to “S11 PUL CONT Q” and set the pulse constant (Pulse/kvarh) based on the calculation below

Figure 13: Pulse Constant Setting

Here is the procedure to calculate what value to enter on the meter for the DO Pulse constant. There are two procedures, one for all Acuvim II series meters and the other for Acuvim II model with firmware below 3.01

Acuvim II (IIR, IIE, IIW) Setup with Firmware 3.01 or Newer

First you will need to figure out how many pulses you will need to represent 1 KWh or how many KWh will represent 1 pulse. The former is focused on smaller consumption.

In this procedure, we will assume 1 pulse = 10kWh is what is needed. Then follow these steps:

  • Multiply the PT ratio and CT ratio i.e. PT1/PT2 * CT1/CT2 Example: PT ratio: 6600V/120V, CT ratio: 2000:5A => 6600/120 * 2000/5 = 22,000 NOTE: If no PTs were used, enter the PT ratio as the default on the meter, i.e. 400/400. If the CT2: 333mV, consider this as 1A for the calculation If this is a Rope CT meter, CT1 = 1000 and CT2 =1
  • Divide 10KWh by 22,000 i.e. (10/22000) kWh = (1/2200) kWh
  • This means 1 pulse = (1/2200) kWh; therefore 2200 pulses = 1 kWh
  • Since we get 2200 pulse/kWh, enter 2200 as the pulse constant into the meter
Acuvim II Setup with Firmware Older than 3.01

First you will need to figure out how many pulses you will need to represent 1 KWh or how many KWh will represent 1 pulse. The former is focused on smaller consumption.

You will need to enter the pulse constant based on the unit. The unit of the pulse constant on the meter is 0.1kWh/pulse.

Therefore, if you need 1 pulse to represent 100kWh i.e. 100kWh/pulse; this is equivalent to: 1000*0.1kWh/pulse. 1000 is the number you will enter as the pulse constant into the meter.

Analog Output (AO)

On 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, you can set the AO mode as 0-5V or 1-5V.

Figure 14: AO Mode Configuration

0: Represents 0-20mA, 1: Represents 4-20mA, 2: Represents 0-5V and 3: Represents 1-5V.

On the ‘AO1 SEL’ Screen:

  • Select the parameter you will like to send out as an analog output through AO1.

On the ‘AO2 SEL’ Screen:

  • Select the parameter you will like to send out as an analog output through AO2.

AXM-IO3 (M31 or M32)

Digital Input (DI)

Digital Input (DI) can be used for pulse counting or for switch status monitoring:

  • Setting the pulse counter enable screen to “0” means DI will be used for status monitoring while setting it to “1” means it will be used for pulse counting.
  • On the pulse counter enable “IO CNTR ENBL” screen: 0001 means DI4 to DI2 are status monitors while DI1 is a pulse counter.
  • On the Pulse Constant “IO CNTR CONT” screen: If DI is a pulse counter, set the pulse constant on this screen. When the number of pulses counted by the DI equals to the pulse constant, the pulse counter number will increase by one.
