metering calculations is done on top of the trace memory sampling. The harmonic analysis 
sampling (256 samples/cycles, 1 cycle) causes the trace memory sampling to stop for one 
cycle whenever a harmonic analysis is requested. Refer to 4.5.3 Trace Memory for details 
on trace memory implementation in the EnerVista PQMII Setup Software.
•TRACE MEMORY USAGE: The trace memory feature allows the user to capture 
maximum of 36 cycles. The 
TRACE MEMORY USAGE setpoint allows the buffer to be divided 
into maximum of 3 separate buffers as shown in table below.

CHAPTER 5: SETPOINTS
•TRACE MEMORY TRIGGER MODE: The trace memory can be conf igured to trigger in 
two different modes as described in the table below.
•Ia/Ib/Ic/In OVERCURRENT TRIG LEVEL: Once the phase A/B/C/neutral current equals 
or increases above this setpoint value, the trace memory is triggered and data on all 
inputs are captured in the buffer. The number of cycles captured depends on the value 
specif ied in the 
TRACE MEMORY USAGE setpoint .
•Va/Vb/Vc OVERVOLTAGE TRIG LEVEL: Once the phase A/B/C voltage equals or 
increases above this setpoint value, the trace memory is triggered and data on all 
inputs are captured in the buffer. The number of cycles captured depends on the value 
specif ied in the 
TRACE MEMORY USAGE setpoint . Phase to neutral levels are used 
regardless of the VT wiring.
•Va/Vb/Vc UNDERVOLTAGE TRIG LEVEL: Once the phase A/B/C voltage is equal to or 
less than this setpoint value, the trace memory is triggered and data on all inputs are 
captured in the buffer. The number of cycles captured depends on the value specif ied 
in the 
TRACE MEMORY USAGE setpoint .
•SWITCH INPUT A(D) TRIG: If the setpoint is set to “Open-to-Closed”, the trace memory 
is triggered and data on all inputs are captured in the buffer on a Switch A(D) close 
transition. If the setpoint is set to “Closed-to-Open”, the trace memory is triggered and 
data on all inputs are captured in the buffer on a Switch A(D) open transition. The 
number of cycles captured depends on the value specif ied in the 
TRACE MEMORY USAGE 
setpoint .
•TRACE MEMORY TRIGGER DELAY: In some applications it may be necessary to delay 
the trigger point to observe the data before the fault occurred. The PQMII allows the 
trigger to be delayed by the amount of cycles set in this setpoint . Therefore, buffer will 
always contain the number cycles specif ied in this setpoint before the trigger point 
and the remaining space in the buffer is f illed with the cycles after the trigger point .
•TRACE MEMORY TRIGGER RELAY: The relay selected here will be activated upon the 
occurrence of a Trace Memory Trigger. This relay will be cleared once the Trace 
Memory is re-armed.
See 7.4 Triggered Trace Memory for additional details on this feature.
Setpoint Value Result
1 x 36 cycles Upon a trigger, the entire buffer is f illed with 36 cycles of data.
2 x 18 cyclesThe buffer is split into 2 separate buffers and upon a trigger, the 
f irst buffer is f illed with 18 cycles of data and upon a second 
trigger, the second buffer is filled with 18 cycles of data.
3 x 12 cyclesThe buffer is split into 3 separate buffers and upon a trigger, the 
f irst buffer is f illed with 12 cycles of data, upon a second trigger, 
the second buffer is f illed with 12 cycles of data and upon a 
third trigger, the third buffer is f illed with 12 cycles of data.
Setpoint Value Result
One ShotThe trace memory will be triggered once per buffer as def ined 
in the TRACE MEMORY USAGE setpoint above. In order for it to 
re-trigger, it must be re-armed through the serial port using the 
EnerVista PQMII Setup Software or other software. Once re-
armed the trace memory will default back to the f irst buffer.
RetriggerThe trace memory will automatically re-trigger upon each 
condition and overwrite the previous buffer data.

precaution until a valid CT value is entered. Ensure that the CT is connected to the 
correct 1 or 5 A terminals to match the CT secondary.
•NEUTRAL CURRENT SENSING: Neutral current sensing can be accomplished by using 
a separate external CT connection or by calculations. Select “Separate CT” when using 
an external CT. If “Calculated” is selected, the PQMII calculates the neutral current 
using the vector sum of Ia + Ib + Ic = In. If a residual connection is required using the 
PQMII internal CT, the neutral CT primary must be the same as the phase CT primary to 
ensure correct readings.
•NEUTRAL CT PRIMARY: This message is visible only if the neutral current sensing 
setpoint is set to “Separate CT”. Enter the CT primary current . For example, if a 50:5 CT 
is installed for neutral sensing enter 50. One amp CTs can also be used for neutral 
sensing.
•VT WIRING: Enter the VT connection of the system in this setpoint . The three possible 
wiring conf igurations are Wye, Delta, and Single Phase.
If the system to be measured is a Wye connection, the selections are “4 Wire Wye 
Direct”, “4 Wire Wye / 3 VTs”, and “4 Wire Wye /2 VTs”. The “4 Wire Wye Direct” value is 
used for systems that are 600 V or less and directly connected to the PQMII. The 
VT 
NOMINAL SECONDARY VOLTAGE
 setpoint is replaced by NOMINAL DIRECT INPUT VOLTAGE. With 
external VTs (depending upon how many external VTs are used), the “4 Wire Wye / 3 
VTs” or “4 Wire Wye / 2 VTs” value must be selected. Note that when using the “4 Wire 
Wye / 2 VTs” value, only two voltages are measured; the third voltage is calculated on 
the assumption that Van + Vbn + Vcn = 0. This assumption is valid only for balanced 
system voltages.
If the system to be measured is a Delta connection, the values are “3 Wire Direct” and 
“3 Wire Delta / 2 VTs”. The “3 Wire Direct” value should be used for systems that are 
600 V or less and directly connected to the PQMII. With external VTs, “3 Wire Delta / 2 
VTs” must be selected.
The PQMII accepts input voltages from 0 to 600 V AC between any two of the voltage 
terminals (V1, V2, V3, and Vn). These inputs can be directly connected or supplied via 
external VTs. External VTs are required for input voltages greater than 600 V AC (line-
to-line). When measuring line-to-line quantities using inputs V1, V2 and V3, ensure 
that the voltage common input Vn is grounded. This input is used as a reference for 
measuring the voltage inputs.
All connections to the PQMII voltage inputs should be connected using HRC fuses 
rated at 2 amps to ensure adequate interrupting capacity.
•VT RATIO: Enter the voltage transformer ratio. All three voltage inputs must be of the 
same rating. For example, if 4200:120 VTs are used, the 
VT RATIO should be 4200 / 120 = 
35.0:1. This setpoint is not visible if 
VT WIRING is set to “3 Wire Direct”, “4 Wire Direct”, or 
“Single Phase Direct”.
•VT NOMINAL SECONDARY VOLTAGE: Enter the nominal secondary of the VTs. If the 
voltage inputs are directly connected, enter the nominal system voltage that will be 
applied to the PQMII. This setpoint is not visible if the 
VT WIRING is set to “3 Wire Direct”, 
“4 Wire Direct”, or “Single Phase Direct”. This value is used to scale an analog output 
that is assigned to display voltage as a percentage of nominal.
•NOMINAL DIRECT INPUT VOLTAGE: This setpoint is displayed only if VT WIRING is 
selected as a direct connection. The nominal direct input voltage must be entered in

this message. This value will be used to scale an analog output that is assigned to 
display voltage as a percentage of nominal.
•NOMINAL SYSTEM FREQUENCY: Enter the nominal system frequency. The PQMII 
measures frequency from the Van voltage and adjusts its internal sampling to best f it 
the measured frequency. If the Van input is unavailable, the PQMII will assume the 
frequency entered here.
5.3.2 Analog Outputs
PATH: SETPOINTS  S2 SYSTEM SETUP  ANALOG OUTPUT 1(4)
The PQMII has four (4) Analog Outputs conf igured through four setpoints pages. The 
ANALOG OUTPUT RANGE setpoint appears in the Analog Output 1 setpoints page only and 
applies to all four outputs.
•ANALOG OUTPUT RANGE: If the T20 option is installed, the Analog Outputs can be 
conf igured to operate as 4 to 20 mA current sources or 0 to 20 mA current sources. All 
four Analog Outputs will operate in the range def ined by this setpoint .
•ANALOG OUTPUT 1(4) MAIN / ANALOG OUTPUT 1(4) ALT: If the PQMII is used in 
conjunction with programmable controllers, automated equipment , or a chart 
recorder, the analog outputs can be used for continuous monitoring. Although 
parameters can be selected for continuous analog output , all values are available 
digitally through the communications interface. Applications include using a 
computer to automatically shed loads as the frequency decreases by monitoring 
frequency or a chart recorder to plot the loading of a system in a particular process.
Each of the analog outputs can be assigned to two of the parameters listed in the 
Analog Output Parameters table. The analog output main selection is the default 
selection and a programmable switch input can be programmed to multiplex the 
ANALOG OUTPUT 1(4) ALT selection to the same output depending upon the open or closed 
state of the switch input . See 5.3.4 Switch Inputs for details about conf iguring a switch 
input . If no switch input is assigned as an analog output multiplexer, the analog output 
main selection will be the only parameter which appears at the analog output 
terminals. The ability to multiplex two different analog output quantities on one

analog output effectively gives the PQMII eight analog outputs. The table below shows 
the criteria used by the PQMII to decide whether the output is based on MAIN or ALT 
settings.
•MAIN/ALT 4 mA VALUE: This message appears for each analog output and allows the 
user to assign a numeric value which corresponds to the 4 mA end of the 4 to 20 mA 
signal range (T20 option) or the 0 mA end of the 0 to 1 mA signal range (T1 option). The 
numeric value range will depend upon which parameter is selected. See the 
Analog 
Output Parameters
 table below for details. Note that if the T20 option is installed and 
the 
ANALOG OUTPUT RANGE setpoint is set to “0-20 mA”, this message represents the 0 mA 
end of the signal range.
•MAIN/ALT 20 mA VALUE: This message appears for each analog output and allows 
the user to assign a numeric value which corresponds to the 20 mA end of the 4 to 20 
mA signal range (T20 option) or the 1 mA end of the 0 to 1 mA signal range (T1 option). 
The numeric value range will depend upon which parameter is selected. See the 
Analog Output Parameters table below.
If the 4 mA (or 0 mA) value is programmed to be higher than the 20 mA (or 1 mA) value, 
the analog output will decrease towards 4 mA (or 0 mA) as the value increases and the 
analog output will increase towards 20 mA (or 1 mA) as the value decreases. If the 4 
mA (or 0 mA) and 20 mA (or 1 mA) values are programmed to an identical value, the 
output will always be 4 mA (or 0 mA).Table 5–3: Analog Output Selection Criteria
