WARNING
Read the instructions in this manual before performing installation and take note of the following precautions:
Ensure that all incoming AC power and other power sources are turned OFF before performing any work on the instrument. Protect the measurement AC Inputs voltage (V1, V2, V3) with 2A external overcurrent protection device and the power supply source inputs with 5A external overcurrent protection device, located close to the equipment.
Before connecting the instrument to the power source, check the labels on the back of the instrument to ensure that your instrument is equipped with the appropriate power supply voltage, input voltages and currents. Failure to do so may result in serious or even fatal injury and/or equipment damage.
Under no c ircu mstanc es should the instrum ent be connected to a power source if it is damaged.
To prevent potential fire or shock hazard, do not expose the instrument to rain or moisture.
The secondary of an external current transformer must never be allowed to be open circuit when the primary is energized. An open circuit can cause high voltages, possibly resulting in equipment damage, fire and even serious or fatal injury. Ensure that the current transformer wiring is secured using an external strain relief to reduce mechanical strain on the screw terminals, if necessary.
Only qualified personnel familiar with the instrument and its associated electrical equipment must perform setup procedures.
Do not open the instrument under any circumstances when it is connected to a pow er source.
Do not use the instrument for primary protection functions where failure of the device can cause fire, injury or death. The instrument can only be used for secondary protection if needed.

QPS +=
This mode is recommended for electrical networks with low harmonic distortion, commonly with THD < 5% for volts, and THD < 10% for currents. In networks with high harmonics, the second method is preferable.
• When the non-active power calculation mode is selected, active
power is measured directly, apparent power is taken as product S = V x I, where V and I are the RMS volts and amps, and reactive power (called non-active power) is calculated as:

Configuring Digital Inputs
The PowerSmart+ PQM can be provided with four to twelve (depend on DI/O module type) digital inputs that can be linked to control setpoints to give an indication on input status change (see Configuring Alarm/Control
Setpoints), or can be linked to general pulse counters to count incoming
pulses (see Configuring Counters). They can also be linked to the Billing/TOU registers to count pulses from external wattmeters or gas and water meters.

When you select an output parameter for the analog output channel, the default engineering scales are set automatically. They correspond to the maximum available scales. If the parameter actually covers a lower range, you can change the scales to provide a better resolution on an analog output.
PowerSmart+ Power Quality Meter 83
Chapter 5 Configuring the PowerSmart+ PQM General Meter Setup
Scaling Non-Directional Analog Outputs
For non-directional analog outputs with a 0-1mA, 0-20mA or 4-20mA current option, you can change both zero and full engineering scales for any parameter. The engineering scale need not be symmetrical.
Scaling Directional Power Factor
The engineering scale for the signed power factor emulates analog power factor meters.
The power factor scale is -0 to +0 and is symmetrical with regard to
±1.000 (-1.000 ≡ +1.000). The negative power factor is scaled as -1.000
minus the measured value, and non-negative power factor is scaled as +1.000 minus the measured value. To define the entire power factor range from -0 to +0, the default scales are specified as -0.000 to 0.000.
Scaling ±1mA Analog Outputs
Programming engineering scales for directional ±1mA analog outputs depends on whether the output parameter represents unsigned (as volts and amps) or signed (as powers and power factor) values.
For an unsigned output value, you can change both zero and full engineering scales.
For a signed (directional) value, you should only provide the engineering scale for the +1 mA output current.
The engineering scale for the 0 mA output current is always equal to zero for all values except the signed power factor, for which it is set to 1.000 (see Scaling Directional Power Factor above).
The meter does not allow access to the low scale setting if the parameter is directional. Whenever the sign of the output parameter is changed to negative, the meter automatically uses the full engineering scale setting for +1 mA with a negative sign.
Scaling Analog Outputs for 0-2 mA and ±2 mA
The 0-1mA and ±1mA current outputs provide a 100% overload, and actually output currents up to 2 mA and ±2mA whenever the output value exceeds the engineering scale you set for the 1 mA or ±1mA.
The output scales for 0-1 mA and ±1 mA analog outputs are programmed for 0 mA and +1 mA regardless of the required output current range.
To use the entire output range of 2 mA or ±2 mA, set the analog output scales as follows:
• 0-2 mA: set the 1 mA scale to ½ of the required full scale output
for uni-directional parameters, and set the 0 mA scale to the negative full scale and the 1 mA scale to zero for bi-directional parameters.
• ±2 mA: set the 1 mA scale to ½ of the required full-scale output
for both uni-directional and bi-directional parameters.
For example, to provide the 0 to 2 mA output current range for Volts measured by the meter in the range of 0 to 120V, set the 1 mA scale to 60V; then the 120V reading will be scaled to 2 mA.
Configuring Counters
The PowerSmart+ PQM has four six-digit general counters that can count pulses delivered through the device digital inputs with a programmable scale factor. Each counter can also be incremented in response to any internal or external event, checked and cleared through the Control Setpoints.

Configuring Alarm/Control Setpoints
The PowerSmart+ PQM has an embedded logical controller that can perform different actions in response to user-defined internal and external events. Unlike a PLC, the meter uses a simplified programming technique based on setpoints that allows the user to define a logical expression
PowerSmart+ Power Quality Meter 85
Chapter 5 Configuring the PowerSmart+ PQM General Meter Setup
based on measured analog and digital values that produce a required action.
The meter provides 16 control setpoints with programmable operate and release delays. Each setpoint evaluates a logical expression with one trigger argument. Whenever an expression is evaluated as “true”, the setpoint performs a programmable action that can send a command to the output relay, or increment a counter.
The logical controller provides very fast response to events. The scan time for all setpoints is 1 cycle time (16.6 ms at 60Hz and 20 ms at 50/400 Hz).
Using the Front Display
Select Setpoint Setup menu from the Device Setup menu to enter the setup menu. See Viewing and Changing Setup Options in Chapter 3 for information on configuring parameters via the front display.

Figure 5-12: General Setup Dialog Box – Control/Alarm Setpoints Tab
Using Numeric Triggers
For numeric (analog) triggers, you can specify two thresholds for each trigger to provide hysteresis (dead band) for setpoint operations.
The Operate Limit defines the operating threshold, and the second Release Limit defines the release threshold for the trigger. The trigger thresholds are specified in primary units.
PowerSmart+ Power Quality Meter 87
Chapter 5 Configuring the PowerSmart+ PQM General Meter Setup
If you do not want to use hysteresis for the trigger, set the Release Limit to the same value as the Operate Limit.
Using Binary Triggers
Binary (digital) triggers like digital inputs and relays are tested for ON/CLOSED or OFF/OPEN status.
In the PowerSmart+ PQM, the binary events are level-sensitive events. An event is asserted all the time while the corresponding condition exists.
Delaying Setpoint Operations
Two optional delays can be added to each setpoint to extend monitoring triggers for a longer time before reaching a decision on whether the expected event occurred or not. When a delay is specified, the logical controller changes the setpoint status only if all conditions are asserted for a period of at least as long as the delay time.
Using Setpoint Events and Actions
When a setpoint status changes, i.e., a setpoint event is either asserted or de-asserted, the following happens in your meter:
• The new setpoint status is logged to the setpoint status register
that can be monitored through communications from the SCADA system or from a programmable controller in order to give an indication on the expected event.
• The operated setpoint status is latched to the setpoint alarm latch
register that can be inspected through communications and via the display (see Status Display in Chapter 3). The register holds the last setpoint alarm status until it is explicitly cleared through communications or via the display.
• A programmable action is performed on setpoint status transition
when a setpoint event is asserted.
Generally, setpoint actions are performed independently for each setpoint and can be repeated a number of times for the same target. The exceptions are relay operations that are shared for each target relay between all setpoints using an OR scheme.
A relay output is operated when one of the setpoints linked to the relay is activated and remains operated until all of these setpoints are released (except for latched relays that require a separate release command to be deactivated).
Using Time Counters
Any of the general counters can be used to count the setpoint operation time. If you select the TIME CNT n action for a setpoint, the target counter measures the time while the setpoint is in the operated state. The counter resolution is 0.1 hour. See Status Display in Chapter 3 on how to examine the counters via the front display.

Chapter 5 Configuring the PowerSmart+ PQM Configuring Billing/TOU
5.4 Configuring Billing/TOU
The TOU battery-backed clock unit is highly recommended in case of using time-scheduled tariff rates, otherwise a long power outage may cause the meter clock to lose time so your tariff counters would not comply with the calendar schedule.
Billing Energy Registers
The PowerSmart+ PQME/EH has 4 fully programmable billing energy registers that can be linked to any internal energy source or to an external pulse source that delivers pulses through the meter digital inputs.
Any energy register can provide either a single-tariff energy accumulation or be individually linked to the TOU system providing both total and multi­tariff energy billing.
Tariff Rates
The meter tariff structure supports 8 different tariff rates using an arbitrary tariff schedule. A total of 4 types of days and 4 seasons are supported with up to eight tariff changes per day.
Maximum Demand Registers
Any of billing energy registers can be individually linked to the maximum demand register providing the same demand tariff structure as you selected for energy registers.
Recording Billing Data and Load Profiling
The PowerSmart+ PQME/EH can provide automatic recording of the daily energy and maximum demand profile to a data log file. Maximum demand profiling can be individually configured for every register.
See Factory Preset Data Log Files in Chapter 5 and Billing Profile Log File in Appendix E for more information on the file layout and contents.
To configure the billing registers and the tariff system in your meter:
1. Link the billing registers to the respective energy sources.
2. Configure the options for the registers to whether the only totalization or both total and tariff registers would be used, and whether daily profiling should be enabled for the energy usage and maximum demand registers.
3. Configure the daily tariff schedule using the TOU daily profiles for all types of days and seasons.
4. Configure the season tariff schedule using the TOU calendar.
Configuring Billing/Tariff Registers
To configure the billing/TOU registers in your meter:
1. Select Energy/TOU from the Meter Setup menu.

To configure your daily tariff schedule, select Energy/TOU from the Meter Setup menu, and then click on the TOU Daily Profiles tab.
Figure 5-17: Energy/TOU Setup Dialog Box – TOU Daily Profiles Tab
The daily profile setup allows you to specify the daily tariff change points with a 15-minute resolution for 4 seasons using 4 different daily schedules for each season.
To configure your daily profiles:
1. Select the desired season and day type.
2. Select the start time for each tariff change point and the corresponding active tariff number.
3. Repeat the setup for all active profiles.
The first tariff change point is fixed at 00:00 hours, and the last tariff change you specified will be in use until 00:00 hours on the next day.
NOTE
The billing daily profile log file is automatically configured for the number of active tariffs you defined in the meter TOU daily profiles.
Configuring the Season Tariff Schedule
To configure your season tariff schedule, select Energy/TOU from the Meter Setup menu, and then click on the TOU Calendar tab.
PowerSmart+ Power Quality Meter 97
Chapter 5 Configuring the PowerSmart+ PQM Configuring Billing/TOU
Figure 5-18: TOU Calendar Setup Dialog Box – TOU Calendar Tab
The meter TOU calendar allows you to configure any tariff schedule based on any possible utility regulation. The calendar provides 32 entries that allow you to specify profiles for working days and holidays through all seasons in any order that is convenient for you, based on simple intuitive rules.
To configure your season tariff schedule:
1. In the Season/Period box, select the season, and in the Day Type box, select a day type for this calendar entry.
2. Define the time interval when this daily tariff schedule is effective, based on the start and end weekdays and, for a multi-season schedule, on the start and end month for the selected season. It does not matter which order of weekdays or months you select: the meter recognizes the correct order.
3. For exception days like weekends and designated holidays, define a specific day either by a month and a month day, or by selecting a month, a week and a weekday within the month.
There are no limitations on how to build your schedule. A common recommendation is to use minimum time constraints and only when it is needed to avoid ambiguity. You need not to define month days if a daily schedule is effective all days of the month, or to define the start and end months if it is effective through all the year. If you wish to define a specific period within a month using the start and end days, put this entry before allocating the remaining days to another daily schedule without specified month days, so it would be checked first for a match.
The above picture shows a typical single-season tariff schedule with two daily tariff profiles configured for working days, and weekends and the designated U.S.A. holidays.
