Minimum/Maximum Values of Real-Time Measurements

Minimum/Maximum Measurements Rule

Minimum and maximum measurements take into account the absolute value of real-time measurements. Therefore the following rule applies:

0<10<200<-400<600<-3800.

In this case:

the minimum value = 0
the maximum value = -3800

NOTE: This rule does not apply for the power factor (PF) and for the fundamental power factor (cosϕ):

PFmax (or cosϕ max.) is obtained for the smallest positive value of PF (or cosϕ).
PFmin (or cosϕ min.) is obtained for the highest negative value of PF (or cosϕ).

The reset minimum/maximum command (command code = 46728) can reset the content of the minimum/maximum real-time measurement registers.

Minimum of Real-Time Measurements

Registers 1300 to 1599 hold the minimum values of real-time metering parameters:

The register of the minimum value of a real-time metering parameter is equal to the register of the real-time metering parameter plus 300.

Examples
- Register 1300 holds the minimum value of the phase-to-phase voltage V_AB (register 1000).
- Register 1316 holds the minimum value of the current on phase A (register 1016).
The order of the registers is the same as that of the real-time metering variables.
The scale factors of the minimum values are the same as those of the real-time metering parameters.
The minimum values of unbalance current and unbalance voltage are not available.
The minimum values of Imin (register 1026), Vmax (register 1145), and Vmin (register 1146) are not available.

Maximum of Real-Time Measurements

Registers 1600 to 1899 hold the maximum values of real-time metering parameters:

The register of the maximum value of a real-time metering parameter is equal to the register of the real-time metering parameter plus 600.

Examples
- Register 1600 holds the maximum value of the phase-to-phase voltage V_AB (register 1000).
- Register 1616 holds the maximum value of the current on phase A (register 1016).
The order of the registers is the same as that of the real-time metering variables.
The scale factors of the maximum values are the same as those of the real-time metering parameters.
The maximum values of Imin (register 1026), Vmax (register 1145), and Vmin (register 1146) are not available.

Energy Measurements

General Description

The energy measurements are refreshed every second. Energy measurements are saved every hour in the non-volatile memory of the MicroLogic trip unit.

Energy measurements include:

active energy Ep
reactive energy Eq
apparent energy Es
active energy counted positively (EpIn) or negatively (EpOut), according to the configuration of register 3316 Power Flow Sign.
reactive energy counted positively (EqIn) or negatively (EqOut), according to the configuration of register 3316 Power Flow Sign.
active energy and reactive energy are accumulated according to the configuration of register 3324 (absolute mode by factory setting) Energy Accumulation Mode.

The reset minimum/maximum command (command code = 46728) can reset the content of the energy measurement registers, cumulative energy measurements excepted.

NOTE: The power flow sign configuration command (command code =47240) can reset the content of the energy measurement registers excluding the cumulative energy measurements.

Energy Registers

Energies are stored in big-endian format: the most significant word is transmitted first and the least significant second.

Examples

If Ep = 7589 kWh, then:

If Ep = 4,589,625 kWh, then:

4589625 = 70x65536 + 2105

Pre-Alarms

General Description

The EcoStruxure Power Commission software enables the configuration of the following 2 pre-alarms:

long-time protection pre-alarm (PAL Ir)
ground-fault protection pre-alarm (PAL Ig)

Each alarm has a corresponding alarm code:

PAL Ir = 1013
PAL Ig = 1014

Each alarm has a priority level that manages the alarm display on the FDM121 display:

no priority = N/A (not affected)
low priority = 1. No alarm display on the FDM121 display.
medium priority = 2. The FDM121 display LED is steady ON.
high priority = 3. The FDM121 display LED blinks and a pop-up screen informs the user that the alarm is active.

Refer to the PowerPacT H-, J-, and L-Frame MicroLogic 5 and 6 Trip Units - User Guide Related Documents for more information regarding the relationship between alarm priority and FDM121 display.

The pre-alarms registers describe the settings of the pre-alarms:

Load Profile Counters

The load profile counters report the number of hours for each range of current in the MicroLogic trip unit. If the load profile counters reach the maximum value 4 294 967 295 and a new load profile event occurs, then the load profile counters are reset to 0.

A read request of 8 registers is necessary to read the load profile counters.

Time Remaining Until Long-Time Tripping

Time remaining until long-time tripping is evaluated every second. If another protection is tripped, then time remaining until long-time tripping continues to be evaluated.

Time remaining until long-time tripping = 32768 (0x8000) if

long-time protection is already tripped, or
time remaining until long-time tripping is below 1 s, or
no default is detected by long-time protection.

If time remaining until long-time tripping is > 7200 s, then time remaining until long-time tripping = 7200 s.
