VDR Specifications
The PowerWatch VDR
PowerWatch VDR Features
The PowerWatch VDR records surges, sags, impulses, outages and
frequency variations. It is self powered and easy to use - parameters can be
set by a few easy keystrokes from your PC.
The VDR can retain 4,000 events. The existence of recorded events can be
indicated by the VDR's flashing light.
Communication between a PC and the VDR is carried via the Lite-Link
interface cable. By using this optical data transfer, the PC remains electrically
isolated.
Safety Precautions
The VDR is designed and certified to work only on single-phase systems.
Attempting to modify the VDR or operating it improperly may cause circuit
damage which can ultimately result in property damage, personal injury, or
death.
Plugging in a PowerWatch VDR
The VDR is designed to plug into a standard convenience outlet. As a safety
precaution, the unit should be in a place where it can be easily unplugged.
This will also make it accessible for data retrieval. The VDR does not use a
protective earth connection since there are no exposed metal parts. The earth
conductor is used to measure neutral to ground (N-G) events. The ground
prong may be electrically unconnected (as long as it is not exposed). The
2007 ACR Systems Inc.
The PowerWatch Voltage Disturbance Recorder

VDR does not normally need any special ventilation, however, its ambient
temperature should not be allowed to rise above the operating limit.
Electrical Immunity
The VDR's internal circuitry is solid-state with built-in EMI and RFI protection
to ensure reliable readings.
Safety Inspection
We recommend that you inspect the VDR periodically for visible damage. To
ensure that it operates safely, inspect for missing labels, cracks in the case, or
bent blades and/or broken leads.
Battery Care
The VDR contains a lithium battery that will, under normal circumstances,
allow the VDR to operate for 10 years. Exposing the VDR to extreme
temperatures for extended periods of time may reduce battery life by as much
as 50%. The VDR is designed for INDOOR USE. It should not be exposed to
direct sunlight.
To extend battery life, keep the VDR plugged into a standard convenience
outlet (even when not in use).
WARNING: BATTERY POSES FIRE, EXPLOSION AND SEVERE BURN
HAZARD. DO NOT RECHARGE, DISASSEMBLE, HEAT ABOVE 100°C
(212°F), INCINERATE, OR EXPOSE CONTENTS TO WATER
Maintenance
The PowerWatch VDR is a maintenance-free product. However, it is
recommended that it be kept clean to allow for easy visual inspections. To
clean the VDR, unplug it from the outlet and wipe it with a dry, clean cloth.
Product Service
The PowerWatch VDR has no user-serviceable parts inside. The fuse inside
the VDR is NOT OPERATOR-REPLACEABLE. Opening the case, or
attempting to do so, will void the warranty and safety certification. If you
require service, please contact your local dealer or factory representative.

Quick Summary
Quick Summary
Quick Summary displays the number of surge, sag, impulse, and frequency
events as bars on a graph. Outages are included with sags.
The horizontal axis displays time; the vertical axis displays the number of
events that occurred in each time period. In the Quick Summary above, the
time periods are sorted by date.
Note that the thickness of a bar and its position in a time period is irrelevant;
the bar only displays the number of events and the time period they occurred
in.
If more detailed analysis is needed, it may be better to export the file to a
spreadsheet or database for further manipulation.
A Quick Summary can be saved in either a bitmap(BMP) or metafile(WMF)
format. In most cases, a metafile format is preferred since it is smaller, is
easily scaled, and prints better. However, some applications (such as MSPAINT) can only handle the BMP format.
To Edit the graph, right-click anywhere in the graph to open the
Graph Control dialog box.

PowerWatch©
A single impulse event between hot and neutral or neutral and ground can be
displayed as a graph, enabling you to see if the impulse is causing zero
crossings.
An impulse graph is produced using the amplitude, polarity/direction, and
position (in degrees) of the event. The graphical representation is not intended
to show the actual wave form nor does it show the duration of the impulse.
Important To graph an impulse you must choose an event that contains only
one impulse; it is not possible to graph an event consisting of multiple
impulses.

The Event Distribution Graph plots the magnitude of the event against
duration on a logarithmic scale in order to determine the importance of the
data. For example, a single random event may not be as significant as a
cluster of recurring events.
This information can be interpreted using the CBEMA Curve found in
Appendix B, Power Quality Issues, in the PowerWatch Reference Guide.
Since the impulses have a duration that is unknown, they are represented as
having a width of 10 microseconds.

list them on the Communicate menu. Ports that it cannot find either don't exist
or are in use. For example, if your computer has two COM ports (1, 2) and if
COM 1 is being used by the mouse, and COM 2 is unused, then only COM 2
will appear on the Communicate menu.
Clicking on an unchecked port will cause PowerWatch to try to open that port;

Having downloaded a VDR's events, and with the Events tab still open, you
can view and analyze the data that the VDR has gathered since it was last
cleared. A VDR can store 4,000 events.

Event # Column
The Events column displays the number sequence of each event, with the
most recent events displayed first. By using the scroll bar on the right of the
window, all the events that the VDR has recorded can be viewed. The number
0 is given to an Open Event.
Start Time Column
The Start Time column displays the time that an event started. The resolution
of the time stamp in a VDR is eight seconds. Therefore, if an impulse occurred
once every second starting at 12:00:00, the first eight impulses would all be
reported to have the same time of 12:00:00. The next eight impulses would be
reported as having the same time of 12:00:08. Also, if identical information
was downloaded twice from a VDR, the two site reports could show a time
difference of eight seconds.
Event Column
The Event column displays the types of events that occurred during the
reporting period.
Impulse Events An Impulse Event is a transient voltage surge. The event
column will display the number of impulses that the VDR was able to count.
For instance, in the Event tab displayed above, event #8 is one impulse; event
#18 is made up of nine impulses.
Surge and Sag Events Surge and sag events are increases and decreases
in line voltage that are outside the thresholds for at least one full cycle. Surges

can occur on the hot-neutral lines or on the neutral-ground lines. Sags are
only measured on the hot-neutral lines.
Outage Events An Outage Event is a 0 voltage sag (for example, event #16
listed above).
High and Low Frequency Events Frequency events are recorded when the
frequency is outside the preset frequency thresholds.
Loss of Synchronization Excessive harmonics or noise on a power line
may cause severly distorted voltage waveforms. While not common, these
distorted waveforms could result in "extra" zero crossings on the AC line.
PowerWatch synchronizes itself to the consecutive positive and negative zero
crossings of the AC line (every 8.33 milliseconds). Should the voltage
waveform be so highly distorted that unexpected zero crossings are detected,
PowerWatch will report a loss of synchronization relative to the measured
voltage waveform.
Extreme Column
The Extreme column displays the maximum value measured during the event.
End Time/Duration/Degree Column
This column displays the duration of an event, or the time that the event
ended, or, in the case of a single impulse, the event's position on the sine
wave (in degrees).
Information is displayed according to the length of the event.
· Events of less than one second are displayed in number of cycles.
· Events of one to 119 seconds are displayed in seconds. Outages
up to 16 seconds are recorded in 0.5 cycle resolution, otherwise the
outage resolution is eight seconds.
· Events of between two minutes and 24 hours are displayed in
hours, minutes and seconds for example, 07:51:24 (7 hours, 51
minutes, and 24 seconds).
· Events that last longer than 24 hours display the end time (date and
time).
If an event was still in progress when data was downloaded from the VDR, the
event will be designated as an open event in this column. PowerWatch can
display one each of three open event types simultaneously. Open events are
assigned the number zero in the Event # column.

Impulses
Impulses
Impulses are transient voltage fluctuations (sometimes called spikes). They
can be positive or negative and can occur on the hot-neutral line or on the
neutral-ground line. Impulses typically have a duration far below one cycle
time and can be detected below microsecond.
PowerWatch will record any voltage deviation above the impulse limit and of
less than one cycle duration as an impulse event.
5.2.1.3
Impulse events
Impulse Events
Impulses are transient voltage fluctuations (sometimes called spikes), can be
positive or negative, and can occur on both the hot-neutral line and the
neutral-ground line. The voltage potential of an impulse can be quite large;
hundreds of volts is not uncommon. Impulses typically have a duration far
below one cycle time and can be detected below a microsecond. PowerWatch
will record any voltage deviation above the impulse threshold of less than one
cycle duration as an impulse.
PowerWatch can detect both positive and negative impulses down to one
microsecond in duration on both the H-N and N-G lines. If the voltage exceeds
the impulse deviation threshold within one half cycle, an impulse event will be
recorded. An impulse event can include one or more impulses occurring within
the same half cycle. The event column will display the number of impulses
that the PowerWatch was able to count.
An important point to note about a multiple impulse event is that the voltage
reading in the Extreme column will be the total voltage of any impulses that
occur more than 100 microseconds apart. When multiple impulses of different
polarity occur, their absolute values are added together. The degree (in the
fourth column) will be the position in the cycle of the first impulse. The angle of
neutral-ground impulses is referenced to the start of the hot-neutral sine wave.
If an impulse is less than one microsecond in length, PowerWatch will
measure the magnitude of the impulse but may be unable to determine the
polarity. In this case, PowerWatch will show the sign of the impulse as "+"
(firmware version 4 or greater).

Sag Events
Sags are decreases in line voltage lasting for at least one cycle. Sags are only
measured on the hot-neutral lines. Typically, a sag will range from a few volts
to tens of volts below normal.
If the voltage drops below the sag threshold, a sag event will be recorded. If it
drops below 70V, the event will be recorded by PowerWatch as an outage.

Typically, surges are in the order of tens of volts and last from several cycles
to several seconds.
If the voltage exceeds the surge voltage threshold for longer than one cycle, a
surge event will be recorded.

Outage events
Outage Events
When PowerWatch records a sag of below 70Vrms for longer than a second it
displays the event as an outage. The VDR will go into self-powered mode
(battery) and will sample the voltage every eight seconds. As a result, the
shortest outage it will record will be eight seconds. When the power is
reapplied to PowerWatch, the VDR will not detect it immediately, but will wait
until the next eight-second sample before returning to the line powered
operational mode. This delay will prevent contact bounce being reported as an
event when PowerWatch is plugged into a standard electrical outlet.
Since PowerWatch's eight-second clock is not synchronized with outages, it
can sometimes report an outage as 16 seconds when in fact the outage only
lasted for slightly over one second. An example of when this would happen is
if a sag below 70Vrms occurred 6.9 seconds into an eight-second period. At
the 7.9-second point, PowerWatch would change to self powered mode and
report a minimum outage of eight seconds. If then, at the 8.1-second point,
power was restored, the VDR would not sample again until the 16-second
point.

Frequency events are variations in frequency above or below the nominal
frequency (for example, 60Hz in North America and 50Hz in Europe).
Variations in frequency are typically a few cycles and can be from seconds to
minutes in duration.
If the frequency drops below the minimum threshold a low frequency event will
be recorded; if it exceeds the maximum threshold a high frequency event will
be recorded.
The factory default nominal frequency is 60Hz for 110V models and 50Hz for
220V models. However, PowerWatch can be user configured to record at
50Hz and 60Hz for either 110V or 240V models.

PowerWatch Operating Overview
54
PowerWatch synchronizes itself to the consecutive positive and negative zero
crossings of the AC line (every 8.33 milliseconds). Should the voltage
waveform be so highly distorted that unexpected zero crossings are detected,
PowerWatch will report a loss of synchronization relative to the measured
voltage waveform. This Loss of Synchronization will be recorded as an event
until such time as:
· the zero crossing distortion ends; or
· the reported voltage drops below 70V (a detected outage). In this
situation, the Loss of Synchronization event will change to an
Outage event (while keeping the original start time and duration).
PowerWatch has a resolution of 8 seconds, so events shorter than this
duration will have a time stamp of "< 8 seconds".

Modem Overview
Communication with a remote VDR is possible over a telephone line via two
modems: a modem connected to your computer and a modem connected to
the VDR at the remote site. Each modem must be configured before it can be
used for communication.
The configuration instructions we give apply to the USRobotics Sportster
14,400. If your modems are made by another company you will have to check
their manuals to get an equivalent setup string and/or DIP switch settings.
Setting up modem communication can sometimes be problematic; we have
explained the operation as simply as possible in three main steps:
NOTE: Configure the remote station modem before you configure the
computer station modem. The first step in remote modem configuration is:

It is not possible to configure the remote station modem at the remote site.
You must connect the remote station modem to your computer and configure
the remote modem at the computer station before installing it at the remote
site.
DIP switch settings are different for computer station and remote modems.
Because you are configuring the remote modem at the computer station you
must set its DIP switches to computer station settings for the configuring
operation. If your remote station modem has no DIP switches you can skip
this step.
1. Set the DIP switches to the computer station settings. If you have a US

Choose this string if you have a US Robotics modem. If you have another
model of modem check the modem's manual to see if you need to enter a
different setup string.
4. Click Set up Modem.
You will see a "Failed Setup String" message on the status bar at the bottom

2. Open the PowerWatch program and from the menu bar choose the COM
port that the modem is connected to.
The Modem dialog box will appear. Choose the Setup tab.
3. To choose a setup string click the down arrow to the right of the Setup
String box. The strings in this pulldown menu are the default settings for the
US Robotics Sportster 14,400 modem. The computer station setup string for a
US Robotics modem is:
AT&FV0&D2Q0E1&C1B1&B1&H1X0
Choose this string if you have a US Robotics modem. If you have another
model of modem check the modem's manual to see if you need to enter a
different setup string.
If the modem understood the setup string, the message "Initialized modem
successfully" will be displayed on the status bar.

Setting the Dial command
The dial command is the string that commands the modem to initiate a dialing
operation. AT is the command prefix.
If your phone line has tone dial for a touch tone phone, leave the dial
command at ATDT. If your phone line has pulse dial for a rotary phone

change this command to ATDP.
NOTE: If you must always switch to an outside line to dial, you can embed the
code here as well (for example, ATDT9W; the W after the number causes the
modem to wait for another dial tone).
Setting the Timeout
Timeout enables you to set the number of seconds that the PowerWatch
program will wait to connect with the remote station before hanging up.
Leave the default setting at forty-five seconds unless you are placing an
international call, in which case you may need to choose a longer timeout.

Remote modem connection
Before you install the remote modem at the remote station, you want to be
sure that you are able to communicate with it. To save yourself time and
trouble, we suggest that you set up your computer station and your remote
station close to each other on different phone lines (preferably in the same
building) to test their operation.
Connecting the Remote Modem
The remote station consists of a PowerWatch VDR, an LIC-100 Lite-Link
interface cable, a 9- to 25-pin adapter, an MA-100, and a modem.

Lite-Link Interface Cable
Lite-Link Interface Cable
Many manufacturers of PC software and hardware use serial (COM) port(s). It
is difficult to predict potential serial port conflicts. If the Lite-Link interface
cavle's wand tip is not flashing, ther are a few steps that can be taken in order
to potentially find the source of the problem.
· Make sure that the Lite-Link interface cable is securely plugged in. The
Lite-Link may appear to be properly connected but only be partially plugged
in.
· Try a different serial port. If the PC has more than one serial port, try
another port to see if the Lite-Linnk flashes.
· Determine if you have any other Windows programs using the serial
port. PC faxing programs or other programs that use the COM port can
cause conflicts during data transmission. To verify that no other programs
are running and causing comunication problems, shut down your computer
and restart if before you run the PowerWatch program.
· Verify that your serial port settings are correct. In Windows 3.1, use the
Microsoft Diagnostics program, MSD.EXE, to find out the number of
installed serial ports in you PC, and their settings. These settings should be
the same as those displayed in the advanced section of "Ports" in the
Windows 3.1 Control Panel. Exit Windows or restart the computer in MSDOS mode before running MSD. If an internal modem is used, MSD may
detect the modem's serial port. This serial port cannot be directly used with
the Lite-Link.
Windows 95 users can verify port settings using Device Manager. Device
Manager is found on the Task Bar by choosing Start, Settings, Control
Panel, Systems, and Device Manager.

· Verify that your serial port is functioning properly. Use any standard
Windows communications program to ensure the port is functioning.
Examples include: ProComm, Windows 3.1 Terminal or Windows 95
Hyperterminal.
Exit all programs (including PowerWatch) and connect the Lite-Link to the

port. Run the communications software and set the local echo to "off" and
hardware flow control control to "none". When using Hyperterminal, choose a
direct connection to the port. Open the port with the communication software.
Any alphanumeric character typed on the keyboard should cause the Lite-Link
to flash, and the character to appear on the screen.
If the Lite-Link does not flash during typing, the Lite-Link may need repair.
If the Lite-Link flashes during typing, it should also work with PowerWatch
software. Exit the communications program, and re-start PowerWatch. If LiteLink does not flash when running PowerWatch, re-install PowerWatch
software.
· Check your mouse driver. Certain older or inferior drivers for mice,
trackballs, and laptop "pointers" are known to interfere with serial port
operation. If, after disabling your mouse driver, the Lite-Link functions
normally, try using a high quality mouse driver such as Logitech or
Microsoft.
· Try another computer. An alternative to serial port troubleshooting is to
use a different computer. Another computer with its serial ports set up
correctly will confirm that there is an incorrect set up or software/hardware
conflict with the original PC.

· Verify that the printer is plugged in, turned on, and has paper.
· Verify that Windows is set up correctly. Windows uses its own printer
drivers. Set up is done through the Windows Control Panel. If you need
help, follow the instructions in the Windows 3.1 Guide under
Printers/Setup; in Windows 95, click Help, and choose Troubleshooting
Printers.
· Try printing from another program to eliminate the possibility of a hardware
conflict.
