You can see the unbalance factors on the display. You can also view the values remotely using RS485 communication and MIBLink,
the MIB utility software.
If you use Modbus to collect the unbalance factor data, you need to use these equations to calculate the values:
where Rx = register value.
where Rx = register value.
6.2.13 Maximum and minimum statistics
The MIB stores the maximum and minimum value of this data:
• The three phase-neutral voltages
• The three phase-phase voltages
• The three phase currents
• The power
• The reactive power
• The apparent power
• The power factor
• The frequency
• The system total power demand
• The system total reactive power demand
• The system total apparent power demand
You can see the statistics values on the display. You can also view the values remotely using RS485 communication and MIBLink,
the MIB utility software.
The MIB stores the data in a non-volatile RAM. You can reset the statistics data from the display and using RS485 communication.
6.2.14 Running hour counter
The MIB has a running hour counter that shows the number of hours the MIB has been connected to the auxiliary supply. You can
see the counter on the display. You can also view the counter remotely using RS485 communication and MIBLink, the MIB utility
software.
If you use Modbus to collect the data, you need to use this equation to calculate the running hour (RH) values:
where Rx = register value.
