Display Diagnostics
The display may indicate a connection error as shown on the left picture if it fails to establish a connection with the meter. Check the connection between the display module and the meter body. If the error message is still displayed, contact your local distributor.
Numeric LED Display
The meter has a simple user interface that allows you to view numerous measurement parameters by scrolling through different display pages. The
32 Series PM172 Powermeters
Chapter 3 Display Operations
Data Display numeric LED display shows up to three parameters at a time. Small rectangular or triangular LEDs at right and below the display indicate the displayed parameters and their measurement units.
The display layout may change depending on the meter type and mode of operation. There are three modes of display operation: data display, status display, and programming mode display.
Load Bar Graph
The load bar graph displays the amount, in percent (40% to 110%), of the present current load with respect to user-defined nominal load current. The reference nominal current can be set up in amps through the Display Setup menu. If it is set to 0 (default), the current load is referenced to the specified
CT primary current.
Energy Pulse LED
The PM172E and PM172EH have a red “Energy Pulse” LED. It flashes at a constant rate when a load is applied to the meter. There are two modes of
LED operation: normal and test. In normal mode, the LED pulses indicate imported Wh at a rate of 1,000 pulses per kWh in secondary units. In test mode, the LED pulses indicate either imported Wh, or imported (inductive) varh at a rate of 10,000 pulses per kWh/kvarh. The energy test mode can be enabled through the Display Setup menu. When in test mode, the energy and demand accumulators do not account for consumed energy.
Port Activity LEDs
The meter has two yellow LEDs “COM1” and “COM2”, which indicate activity on the two communication ports. The port’s LED flashes when the port is receiving or transmitting data. With the Ethernet or Profibus option, the
“COM1” LED flashes constantly regardless of the port activity.
When the display module is connected remotely through a 3-wire RS-485 interface, the “COM1” LED indicates the display port activity, while the
“COM2” LED is not operational.
Navigation Buttons
The PM172 is provided with six push buttons that are normally used to navigate between different measurement displays. In programming mode, the buttons access the device setup menus and the default factory-set device settings can be changed.
Data Display
In data mode, the display is normally updated once per second; you can adjust the display update rate via the Display Setup menu.
Display Features
Measurement Units
Currents are always displayed in amperes with two decimal places.
Measurement units for voltage and power depend on the connection scheme of the meter:
• When direct wiring is used, voltages are displayed in volts with one decimal place, and power in kilowatts with three decimal places.
Series PM172 Powermeters 33
Chapter 3 Display Operations
• When wiring via PT is used, for the PT ratio up to and including 4.0, voltages are displayed in volts, and power in whole kilowatts.
Data Display
• For the PT ratio above 4.0, voltages are displayed in kilovolts, and power in megawatts with three decimal places.
The small round “Kilo” and “Mega” LEDs light up showing the appropriate measurement units for a displayed page.
Primary and Secondary Volts
Volts can be displayed in primary (default) or secondary units. The volts display mode can be changed through the Display Setup menu.
Phase Power Readings
In configurations with the neutral wire, in addition to total three-phase powers, the meter can show per-phase power readings. By default, they are disabled. See Display Setup on how to enable per-phase power readings in your meter.
Fundamental Component
The meter can display total power factor and active power for the fundamental component if it is enabled through the Display Setup menu.
Whenever phase power readings are allowed, the PM172 also displays perphase power factor and active power for the fundamental component.
Auto Return
If no buttons are pressed for 30 seconds while the display Auto Return option is enabled, the display automatically returns to the main screen from any other measurement display or programming mode.
The Auto Return option can be enabled through the Display Setup menu
Auto Scroll
If no buttons are pressed for 30 seconds while in the common measurements display, and the Auto Scroll option is enabled in the meter, the display automatically scrolls through all available pages. The scroll interval can be adjusted through the Display Setup menu.
To stop auto scrolling, press briefly the SCROLL button.

Data Display
Pressing both the UP and DOWN arrow buttons together returns to the first page within the current display.
The SELECT button operates once it’s released. The button has two functions:
•
When pressed briefly, it switches to programming mode.
•
When pressed together with the ENTER button for more than 5 seconds, it resets Min/Max records, maximum demands, or energies depending on the currently displayed page. If the meter is password protected and a simple reset of data from the display is not allowed, the action has no effect.
The ENERGY button switches to the Energy display in the PM172E and
PM172EH. In the PM172P, the button is not operational. If TOU registers are configured in the meter, you can repeatedly press this button to scroll through all available TOU registers. When briefly pressed once again, it switches back to the common measurements display
Simple Reset of Accumulated Data
When the meter is not password protected, or the simple reset of data is allowed from the display regardless of the security setting (see “Display
Setup”), the meter allows the simple “two-button’ reset of the Min/Max registers, maximum demands, energies, and counters from the data display mode without entering the reset menu:
1. Select a display page where the data you want to reset is displayed:
Min/Max log - select a Min/Max page from the Min/Max Display.
Ampere and volt maximum demands - select the ampere or volt maximum demand page from the Min/Max Display.
Power maximum demands - select the power maximum demand page from the Min/Max Display.
Total and phase energies - select a total energy, or phase energy page from the Energy Display.
Counters – select a counter page from the Status Display

To configure an EGD exchange:
1. Select a desired exchange ID.
2. Specify a destination IP address of the data-consuming node.
3. Specify the production period for the exchange. The
PM172 exchanges provide production rates from 70 ms to
10 minutes in 10 ms increments. Though lower settings are allowed, the actual production period in most cases will not be less than 70 ms.
4. Select “Enabled” in the Exchange Status box to enable the exchange operations.
5. Define address ranges for the points to be sent via the exchange and the data element type for each address range. Up to 30 point ranges can be selected for each exchange that may identify a single point or a range of contiguous points.
Specify the data ranges using the range start point and end point identifiers (ID) in decimal notation. For the available device data points and their IDs, refer the
Series PM172 Powermeters
Chapter 4 PAS Application Software
Configuring Communications in your Meter
PM172 GE EGD Communications Protocol Reference
Guide.
Select a desired data type for the point range. Data transferred through the exchange can be represented in word (16-bit) or double word (32-bit) integer format, or in
IEEE single precision floating-point format.
As you specify an address range for the exchange, PAS immediately shows you the data offset in bytes in the production data area for the following range. Each exchange can send a total of 480 bytes of production data. PAS automatically truncates your range if you specify more data than the exchange can accommodate.
To indicate the end of the address range list, put a zero start point ID in the range following the last range you specified.
6. Click on Send to download your new setup to the meter.
The device will reject your setup if you specified an inexistent start point ID for one of the address ranges. If you specified more points in a range than the device can provide, it truncates the range to the maximum number of points available.
From this dialog box, you can also temporarily put a configured exchange into the pending (disabled) state, and then resume (enable) it whenever needed.
NOTE
When you change the consumer IP address for an exchange through the
Ethernet, the device port restarts so communications will be temporarily lost.
You may need to wait some additional time until PAS restores a connection with your device.

When the daylight saving time is enabled, the meter automatically advances the device clock one hour (by default at 02.00 AM) when daylight saving time begins and puts the clock back one hour (by default at 02.00 AM) when it ends. The default daylight saving time change points are preset for the
U.S.A.
The daylight saving time option is disabled in the PM172 by default. If the daylight saving time option is disabled, you need to manually adjust the device clock for daylight saving time.
Time Synchronization Pulses
External time synchronization pulses can be delivered through one of the digital inputs. If a digital input is selected as the time synchronization source, the edge of an external pulse adjusts the device clock at the nearest whole minute. The time accuracy could be affected by the debounce time of the digital input, and by the operation delay of the external relay.
Using Digital Inputs
The meter is provided with two digital inputs that can trigger the alarm/control setpoints to give an alarm on input status change, or can be linked to the energy/TOU registers to count pulses from external watt meters, or gas and water meters.
To configure them in your device, select the device site from the list box on the PAS toolbar, select General Setup from the Meter Setup menu, and then click on the Digital Inputs tab.

Description
In pulse mode, either leading, or trailing edge of the input pulse is recognized as an event. In KYZ mode, both leading and trailing edges of the input pulse are recognized as separate events.
NORMAL For the normal polarity, the open to closed transition is considered a pulse. For the inverting polarity, the closed to open transition is considered a pulse.
It has no meaning in KYZ mode where both transitions are used.
Debounce time 1-1000 ms 10 ms The amount of time while the state of the digital input should not change to be recognized as a new state. Too low debounce time could produce multiple events on the input change.

Latched mode: the relay goes into its active state when the control setpoint goes into active state and remains in the active state until it is returned into its non-active state by a remote command.
Pulse mode: the relay goes into its active state for the specified time, goes into non-active state for the specified time and remains in the non-active state.
KYZ mode: the relay generates transition pulses. The relay changes its output state upon each command and remains in this state until the next command.
With normal polarity, the relay is normally de-energized in its non-active state and is energized in its active
(operated) state.
With inverting polarity, the relay is normally energized in its non-active state and is de-energized in its active
(operated) state. It is called failsafe relay operation.
Applicable for latched relays.
In non-retentive mode, the relay always returns to its non-active state upon power up.

Programming Analog Inputs
General Meter Setup
The PM172 can be provided with two optional analog inputs with options for
0-1mA, ±1mA, 0-20mA or 4-20mA input currents, depending on the order.
Inputs with 0-1mA and ±1mA options can accept ×200% overload currents, i.e., can actually accommodate currents in the range of 0-2 mA and ±2mA.
The meter automatically converts the analog input readings received from the analog-to-digital converter to the user-defined engineering scale and shows the input values in true engineering units, for example, in volts, amps, or degrees, with the desired resolution.
To configure the Analog Inputs in your device, select General Setup from the

Scaling Non-directional Analog Inputs
For non-directional analog inputs with the 0-1mA, 0-20mA and 4-20mA current options, provide both zero and full engineering scales. Each of the scales operates independently.
Scaling ±1mA Analog Inputs
For directional ±1mA analog inputs, you should provide only the engineering scale for the +1 mA input current. The engineering scale for the 0 mA input current is always equal to zero. The device does not allow you to access this setting. Whenever the direction of the input current is changed to negative, the device automatically uses your full engineering scale settings for +1 mA with a negative sign.
Scaling Analog Inputs for 0-2 mA and ±2 mA
The input scales for 0-1 mA and ±1 mA analog inputs are always programmed for 0 mA and +1 mA regardless of the desired input range. If you want to use the entire input range of 2 mA or ±2 mA, set the analog input scales in your device as follows:
0-2 mA: set the 1 mA scale to 1/2 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 1/2 of the required full-scale output for both uni-directional and bi-directional parameters.
For example, to convert voltage readings from the analog transducer that transmits them in the range of 0 to 2 mA to the range 0 to 120V, set the full range for the +1 mA analog input to 60V; then the 2 mA reading is scaled to
120V.
Programming Analog Outputs
The meter can be ordered with two optional analog outputs with options for
0-1mA, ±1mA, 0-20mA or 4-20mA output currents.
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 set for the 1 mA or ±1mA.
To configure the Analog Outputs in your device, select General Setup from the Meter Setup menu, and then click on the Analog Outputs tab. If you are programming your device online, analog outputs are designated as not available if they are not present in the device.

When you select an output parameter for the analog output channel, the default engineering scales are set automatically. They represent the maximum available scales. If the parameter actually covers a lower range, you can change the scales to provide a better resolution on the analog outputs.
Scaling Non-directional Analog Outputs
When programming scales 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). Negative power factor is scaled as
-1.000 minus measured value, and non-negative power factor is scaled as
+1.000 minus 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.
If the output value is unsigned, you can change both zero and full engineering scales.
If the parameter represents a signed (directional) value, you should provide only 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 device does not allow you access to this setting if the parameter is directional. Whenever the sign of the output parameter is changed to negative, the device automatically uses your full engineering scale settings for +1 mA with a negative sign.

Scaling Analog Outputs for 0-2 mA and ±2 mA
The output scales for 0-1 mA and ±1 mA analog outputs are programmed for
0 mA and +1 mA regardless of the desired output current range. To use the entire output range of 2 mA or ±2 mA, set the analog output scales in your device as follows:
0-2 mA: set the 1 mA scale to 1/2 of the required full scale output for unidirectional 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 1/2 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.
Programming the Analog Expander
Your meter can support up to two analog expanders that are connected through a serial RS-422 interface to the meter port COM2. Each expander has its own address 0 or 1 on the serial interface and provides 8 analog channels with options for 0-1mA, ±1mA, 0-20mA or 4-20mA output currents.
To configure the Analog Expander outputs in your device, select General
Setup from the Meter Setup menu, and then click on the Analog Expander tab.
The expanded analog outputs are enumerated in the following manner: analog output channels 1 through 8 are associated with the analog expander with address 0, while channels 9 through 16 are associated with the analog expander with address 1.
The available analog expander outputs options are described in the following table.

You can preset a counter to a desired value or clear it through this dialog without affecting the counter setup. Check the Online button on the PAS toolbar before entering the setup dialog, type in the desired value into the
Counter Value box, and then click Send.
Using Periodic Timers
The PM172E and PM172EH provide two programmable interval timers that can be used for periodic recording and triggering operations on a time basis through the Control Setpoints. When a pre-programmed timer interval expires, the timer generates an internal event that can trigger any setpoint
(see “Using Alarm/Control Setpoints”).
To configure the device timers, select General Setup from the Meter Setup menu, and then click on the Periodic Timers tab.
To run a periodic timer, specify a non-zero time period for the timer. The time period can be set from 1 to 9999 seconds.
To stop a timer, set the time period to zero.
Using Control Setpoints
The PM172 has an embedded logical controller that runs 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 based on measured analog and digital values that produce a required action.
Series PM172 Powermeters 77
Chapter 4 PAS Application Software
General Meter Setup
The meter provides 16 control setpoints with programmable operate and release delays. Each setpoint evaluates a logical expression with up to four arguments using OR/AND logic. Whenever an expression is evaluated as
“true”, the setpoint performs up to four concurrent actions that can send a command to the output relays, increment or decrement a counter, or trigger a recorder.
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).
To program the setpoints, select General Setup from the Meter Setup menu, and then click on the Control/Alarm Setpoints tab.
The available setpoint options are described in the following table.

Chapter 4 PAS Application Software
General Meter Setup
Setpoint #1 is factory preset to provide standard periodic data logs on a 15minute time basis. It is linked to the device clock and runs data logs #1 and
#2 at 15-minute boundaries of an hour.
Using Logical Expressions
Logical operators OR/AND are treated in a simplified manner. They have no specific priority or precedence rules.
Any trigger condition bound to the logical expression by the OR operator and evaluated as “true” will override any preceding condition evaluated as “false”.
Similarly, any trigger condition evaluated as “false” and bound by the AND operator will override any condition evaluated before it as “true”.
To avoid confusion, it is recommended not to alternate different logical operators in one expression. Instead, bring all conditions that use the same logical operator together at one side of the expression, and the others - at the opposite side.
To explicitly override all other conditions with the critical trigger, put it at the end of the expression using the OR operator if you want the setpoint to be operated anyway when the trigger condition is asserted, and with the AND operator, if the setpoint should not be operated while the critical trigger is not asserted.
Using Numeric Triggers
For numeric (analog) triggers, a setpoint allows you to 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.
If you do not want to use hysteresis for the trigger, set the Release Limit to the same as the Operate Limit.
Using Binary Triggers
Binary (digital) triggers, like digital inputs, relays, or internal static and pulsed events, are tested for ON (closed/set) or OFF (open/cleared) status.
The binary events are divided into two types: static events and pulsed events. Static events are level-sensitive events. A static event is asserted all the time while the corresponding condition exists. Examples are digital inputs, relays and event flags.
Pulsed events are edge-sensitive events with auto-reset. A pulsed event is generated for a trigger only once when a positive transition edge is detected on the trigger input. The examples of pulsed events are pulse inputs
(transition pulses on the digital inputs), internal pulsed events (energy pulses and time interval pulses), and events generated by the interval timers. The logical controller automatically clears pulsed events at the end of each scan, so that triggers that used pulsed events are prevented from being triggered by the same event once again.
Using Event Flags
The PM172EH provides 8 common binary flags, called event flags, which can be individually set, cleared and tested through setpoints and via communications.
Event flags can be used in different applications, for example, to transfer events between setpoints in order to expand a logical expression or a list of actions that have to be done for a specific event, or to externally trigger setpoint actions from the SCADA system or from a PLC through communications.
Using Interval Timers
The PM172E and PM172EH provide two interval timers that are commonly used for periodic recording of interval data at the time of the fault or in the presence of other events detected by a setpoint. The timers can be
Series PM172 Powermeters 79
Chapter 4 PAS Application Software
General Meter Setup programmed to generate periodic events at user-defined intervals (see
“Using Periodic Timers”).
Interval timers are not synchronized with the clock. When you run a timer, it generates a pulsed event that can trigger a setpoint if you have put the timer into a list of the setpoint triggers. When the setpoint event is asserted, the timer is restarted, and then generates the next event when the timer interval expires.
If you want to record interval data at predefined intervals without linking to other events, just select a timer as a setpoint trigger and specify a data log file you want to use for recording, in the setpoint actions list. If you want the periodic data to be recorded in presence of a specific event, select triggers that will identify your event, and then add the timer at the end of the trigger list using the AND operator.
Using Time Triggers
If you want the setpoint actions to be synchronized with the clock, for example, to provide synchronous recording interval data each 15 minutes or each hour, or to output time pulses through relay contacts, use the time triggers that generate static events synchronized to the device clock.
You can exercise the default setting for Setpoint #1 in your device as an example of using time triggers. The setpoint is pre-programmed for data profiling at 15-minute intervals using data logs #1 and #2.
Using the Voltage Disturbance Trigger
The PM172EH provides the voltage disturbance trigger (found under the
VOLT DISTURB name) that detects all types of the voltage waveshape faults on any phase caused by fast transient voltages. You can use it for recording disturbances.
The operate threshold for the voltage disturbance trigger defines the maximum allowable voltage deviation from the steady-state level above which the device will declare a waveshape fault. By default, it is specified as a percent of the nominal device voltage. If you wish to use volts units instead, you can select the desired voltage disturbance units from the
Preferences tab in the Tools/Options/Preferences dialog.
Ì
The voltage waveforms in 4LN3, 4LL3, 3LN3, 3LL3, 3BLN3 and 3BLL3 wiring modes represent line-to-neutral voltages; otherwise, they will be lineto-line voltages. Take it into account when specifying the nominal device voltage that is used as a reference for the disturbance trigger.
The trigger does not respond to slow voltage variations whenever the voltage rise above or drop below the specified threshold takes longer than 1 cycle time.
Delaying Setpoint Operations
Two optional delays can be added to each setpoint to extend monitoring setpoint triggers for a longer time before making a decision on whether the expected event occurred or not. When a delay is specified, the logical controller will change the setpoint status only if all conditions are asserted for a period at least as long as the delay time.
Note that you cannot use delays with pulsed events since they are cleared immediately and will no longer exist on the next setpoint scan.
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 device:
1. 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
80 Series PM172 Powermeters
Chapter 4 PAS Application Software
General Meter Setup controller in order to give an indication on the expected event.
2. The operated setpoint status is latched to the setpoint alarm latch register accessible through communications.
The register holds the last setpoint alarm status until it is explicitly cleared through communications.
3. Up to four programmable actions can be performed in sequence 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, data logging and waveform logging that are shared for each separate target between all setpoints using an OR scheme.
A relay output is operated when one of the setpoints linked to the relay is activated and will stay in the operated state until all of these setpoints are released (except for latched relays that require a separate release command to be deactivated).
Data logging and waveform logging directed to the same file are done once for the first setpoint among those that specify the same action, guaranteeing that there will not be repeated records related to the same time.
Recording Setpoint Events
Time-tagged setpoint events can be recorded to the device Event Log if you put a corresponding action into the setpoint action list. The Event Recorder will log any setpoint transition event: both when the setpoint is operated, and when it is released. The Event Recorder will put into a log file a separate record for each active trigger caused a setpoint status transition, and a separate record for each action done on the setpoint activation (except for data logging actions that are not recorded to the Event Log).

6. Click OK and send your setup to the meter or save to the database.
Configuring the Waveform Recorder
Waveform log files are organized as multi-section files that store data for each recording channel in a separate section. A waveform log file stores 6 channels simultaneously: three voltage and three current channels.
A single waveform record for a channel contains 512 points of the sampled input signal. If a waveform log is configured to record more samples per event than a single record can hold, the waveform recorder stores as many records per event as required to record the entire event. All waveform records related to the event are merged in a series and have the same series number, so that they can be plotted together.
The PM172EH supports two waveform files that record waveforms at two fixed sampling rates:
• Waveform Log #1 – at 32 samples/cycle
• Waveform Log #2 – at 128 samples/cycle
To configure a waveform log file:
1. Double click on a waveform log partition with the left mouse button.
2. Select a file type for your file.
3. Select the maximum number of records you want to be recorded in the file.
The number of records in the waveform log file needed to store one waveform event (series) is defined as follows:
Series PM172 Powermeters
Number of Records per Series = Sampling Rate (Samples per Cycle) x
Number of Cycles per Event / 512
The total number of records you must allocate to store the required number of events (series) is defined as follows:
Number of Records = Number of Records per Series x Number of Series
For example, if you want to record a 64-cycle waveform sampled at a rate of 32 samples per cycle, the number of records required for one waveform series would be:
Number of Records per Series = (32 x 64)/512 = 4.
If you want to allocate space sufficient to store 20 waveform events (series), you should set up the waveform log file for 4 x 20 = 80 records.
4. Click OK, and send your setup to the meter or save to the database.
5. Click “Setup Recorder”, or click on the “Waveform
Recorder” tab.

Configuring DNP Event Classes
The PM172 can generate object change events for any static analog input, binary input and binary counter point when a corresponding point either exceeds a predefined threshold, or the point status changes. A total of 64 change event points are available for monitoring.
Object change events are normally polled via DNP Class 1, Class 2 or Class
3 requests. You can link any change event point to any event class upon the event priority. Refer to the PM172 DNP3 Reference Guide for more information on polling event classes via DNP.
A change event point index is normally the same as for the corresponding static object point. If you wish to use independent numeration for event
Series PM172 Powermeters
Chapter 4 PAS Application Software
Configuring Communication Protocols points, enable re-mapping event point indices via DNP Options setup (see above) so they would start with index 0.
You should define a separate event setpoint for each static object point you wish to be monitored for change events. To view or change the factory-set
DNP event setpoints, select Protocol Setup from the Meter Setup menu and click on the DNP Event Setpoints tab.
The number of event setpoints for each static object type is specified via the
DNP Options setup (see above). Notice that the device clears all event buffers and links the default set of static points to each event object type every time you change the number of points for any of the objects.
To define setpoints for selected static points:
1. Check the “Ext” box if you wish to use the extended point list.
2. Select a parameter group and then a desired parameter for each event point.
3. For AI and BC points, select a relation and an operating threshold or a deadband to be used for detecting events.
All thresholds are specified in primary units. The following relations are available:
Delta – a new event is generated when the absolute value of the difference between the last reported point value and its current value exceeds the specified deadband value;
More than (over) - a new event is generated when the point value rises over the specified threshold, and then when it returns below the threshold minus a predefined return hysteresis – applicable for AI objects;
Less than (under) - a new event is generated when the point value drops below the specified threshold, and then when it returns above the threshold plus a predefined return hysteresis – applicable for AI objects.

PAS can give you indication on whether harmonic levels in the sampled waveforms exceed compliance limits defined by the power quality standards or local regulations.
To review or change harmonic limits:
1. Click on the spectrum window with the right mouse button and select “Limits…”.
112
2. Select a harmonics standard, or select “Custom” and specify your own harmonic limits.
3. Check the Enabled box to visualize harmonic faults on the spectrum graph and in harmonic tables.

Viewing Recorded Files
Harmonics that exceed selected compliance levels are colored in red on the graph and in the tables.
Viewing a Spectrum Table
Click on the button on the local toolbar. The spectrum table displays voltage, current, active power and reactive power harmonic components both in percent of the fundamental and in natural units, and phase angles between the harmonic voltage and current.
To change a phase, click on the window with the right mouse button, select
“Options...”, check the phase you want displayed, and then click OK.
Viewing a Frequency Plot
Click on the button to view a cycle-by-cycle voltage frequency plot.
Viewing Synchronized Waveforms
If you have a number of devices with synchronized clocks, you can view waveforms recorded at different locations in one window. PAS synchronizes the time axes for different waveforms so they could be displayed in a single plot.
To get synchronized waveforms:
1. Put the databases with waveforms into the same folder, or put the sites from which you have uploaded data to the same group in the sites tree.
2. Open a waveform you want to synchronize with other waveforms, and then click on the Multi-site View button . PAS searches for timecoordinated waveforms that have the same time span as the selected waveform.

COMTRADE and PQDIF Converters
COMTRADE and PQDIF Converters
The COMTRADE and PQDIF file converters allow you to convert retrieved waveforms into COMTRADE or PQDIF file format, and data log tables – into
PQDIF format.
Manual Converting
To manually convert your waveforms or a data log into COMTRADE or
PQDIF format:
1. Click on the Export button on the PAS toolbar.
2. Select the database and a waveform or data log table you want to export, and then click Open.
3. Select a directory where you want to store your exported files, type a file name that identifies your files, select a desired file output format, and then click on the Save button. The PQDIF files are commonly recorded in compressed format. If you do not want your files to be compressed, uncheck the Compress box before saving the file.
In COMTRADE format, each waveform event is recorded into a separate file.
A COMTRADE waveform file name contains a site name followed by an ID of the fault or power quality event, which triggered the waveform record.
PQDIF file names contain a site name followed by a timestamp of the first event recorded to the file, and may look like
12KVSUB_20040928T133038.pqd.

To automatically convert your waveform or data log tables into COMTRADE or PQDIF format:
1. Open the Upload Scheduler.
116
2. Highlight a desired device site with the left mouse button, and then click on the Export button.
3. Check the Enabled box for a data log or a waveform log table you want to automatically convert at the upload time.
4. Highlight the Record to… row for the selected table and click on the Browse button.
5. Select a folder where you want to store converted files, type in the converted file’s name, select a desired output file format, and then click on Save.

Appendix E Data Scales
Appendix E Data Scales
The maximum values for volts, amps and power in the PM172 setup and in communications are limited by the voltage and current scale settings. See
in Chapter 4 on how to change the voltage scale in your meter.
The following table defines the meter data scales.

120V+20% = 144V for using with external PT’s, and 690V+20% = 828V for a direct connection to power line.
2
CT Ratio = CT primary current/CT secondary current
3 The default current scale is 2
× CT secondary (2.0A with 1A secondaries and
10.0A with 5A secondaries)
.
