The EM-PULSE is a three channel meter, capable of monitoring
single-phase, two-phase and three-phase systems, as well
as 3 independent single-phase systems with one meter. The
EM-PULSE meter oers 2 pulse outputs and 2 pulse inputs
to maintain exibility during installation and operation. The
EM-PULSE is compatible with all sizes of current/voltage
transducers (CVTs). With the meter’s AutoScale feature, the
pulse scale is set according to the CVT amperage, removing
the need for manual conguration.
Each CVT is independently calibrated to measure and digitally
communicate power values with the meter. The CVT’s exible
rogowski coil makes installations less burdensome. To maintain
high accuracy and exibility for multiple channel installs, high
voltage connections are made directly into each CVT. Each
CVT is rated for installations ranging from 90 to 600V.

oDefault Settings
The EM-PULSE installs with minimal user intervention.
If LEDs are green and you are happy with default factory settings
below, your installation is complete!
Each meter has ve factory default settings. Review the factory
default settings and their denitions below.
Default Setting 1. Pulse Scale
AutoScale is the default factory setting. With AutoScale, pulse
scale is automatically set based on the CVT amperage rating as
follows:
CVT Rated Amps Default Pulse Scale
5-50A 1 Wh/pulse
51-500A 10 Wh/pulse
501-5000A 100 Wh/pulse
5000+A 1 kWh/pulse
Check CVT amperage rating to determine the pulse scale. For
alternative pulse scale settings, see Section 7.1 - Pulse Scale.
Default Setting 2. Pulse/Alarm Options
Fast Pulses (30ms), KY Mode is the default factory setting. Fast
pulses corresponds to a pulse width of 30 milliseconds. In
KY Mode pulses are the representative units and each pulse
output is independent. For alternative pulse widths, KYZ Mode,
or Alarm options see Section 7.2 - Pulse/Alarm Options.
Default Setting 3. Energy Output Type
Total Real ‘Active‘ Energy (P) is the default factory setting. This is
the metric that utility companies typically use for billing.
For alternative Energy Output Types, see Section 7.3 - Energy
Output Type.
Default Setting 4. Balanced Load Multiplier
The Balanced Load Multiplier is disabled in the default factory
settings. For options on balanced load multipliers see Section
7.4 - Balanced Load Multiplier.
Default Setting 5. PowerPrint
PowerPrint is disabled in the default factory settings. For details
on how to utilize PowerPrint see Section 7.5 - PowerPrint.
To Restore Factory Default Settings
Caution: Restoring factory default settings will revert device to
settings listed above. Any manual congurations will be reset.
1. Hold setup button down until all LEDs blink red
(approximately 30 seconds) and release.
2. Momentarily press the setup button again within 5
seconds of the rst release.
3. The LEDs will stop blinking and remain solid red for about
1 second.
4. Meter is now reset to factory default settings.
pConguration Settings
The EM-PULSE meter allows for manual conguation of the
following settings:
1. Pulse Scale
2. Pulse/Alarm Options
3. Energy Output Type
4. Balanced Load Multiplier
5. Powerprint
Each setting has factory default, which can be found in Section

Set based on current energy being monitored
1AutoScale pulse scale is selected based on the largest CVT size
installed. This is the factory default setting for the meter. See
Section 6.1 - Pulse Scale for usage of AutoScale pulse scaling.
2LiveScale takes a sample of energy currently being monitored
and calculates the most appropriate pulse scale after 10
seconds of sampling. LiveScale should be initiated when panel
is fully loaded. This ensures that the automatically chosen pulse
is appropriate to the monitored load while avoiding the pulse
overload warning condition.
Setting 2. Pulse/Alarm Options
Pulse/Alarm Options allow for setting dierent pulse types (KY
vs KYZ) and alarm outputs for alerts of phase loss or changes
from a saved PowerPrint (Setting 5. PowerPrint). There are 6

PowerPrint can only learn and save characteristics for channels
with a properly installed CVT. If the CVT is displaying a
warning or error condition during Normal Operation, take
the corrective action to resolve the installation error prior to
enabling PowerPrint.
When PowerPrint is enabled, it will identify which channels are
active (have properly installed CVTs) and apply the learn and
save characteristics to those channels:
Setting PowerPrint Function
PowerPrint o - default PowerPrint is disabled
PowerPrint on Channel R
PowerPrint enabled for all channels with a
properly installed CVT.
PowerPrint should not be saved if any channels
display an error condition (red LED) during
Normal Operation (See Section 4 - Normal
Operation Mode).
PowerPrint on Channel S
PowerPrint on Channels RT
PowerPrint on Channel T
PowerPrint on Channel RT
PowerPrint on Channel ST
PowerPrint on Channel RST
Once PowerPrint has been turned on and the system
characteristics have been saved, the alarm conditions below
will be displayed on the meter LEDs as a warning or error
during Normal Operation (See Section 4 - Normal Operation
Mode):
Alarm Condition Parameter
Missing sensor CVT missing on one or more channels

PowerPrint Alarm Mode: In addition to the LED indicators
above, the PowerPrint can also alert via an output alarm when
a PowerPrint warning condition is present. This requires the
user to select Alarm Mode in Setting 2. Pulse/Alarm Options.
With PowerPrint On and Alarm Mode selected, the meter will
now display warning conditions on the LEDs and provide an
alarm output to the controller.
Alarm Mode: Output 2 provides a normally open alarm output.
The default alarm is for phase loss of one or more channels
in a multi-phase installation. Alarm mode will also convert
output 1 to the total import and export energy sensed by the
meter. See Section 3 - Wiring: Pulse Output Wiring Options.
PowerPrint Alarm Mode: When PowerPrint is turned on Output
2 provides a normally open alarm output for all PowerPrint
alarm conditions. See Setting 5. PowerPrint below for all alarm
conditions. Alarm mode will also convert output 1 to the total
import and export energy sensed by the meter. See Section 3 -
Wiring: Pulse Output Wiring Options.
Setting 3. Energy Output Type
There are 4 Energy Output Type settings in the EM-PULSE
meter: Total Real ‘Active’Energy, Net Real ‘Active’Energy,
Reactive Energy, and Apparent Energy.
Setting Energy Units
Total Real ‘Active’ Energy
1
(P) - default Measured in watts (Wh or kWh) Meter will output total import and export
energy of all CVT channels
Net Real ‘Active’ Energy
2
(P
net
) Measured in watts (Wh or kWh)
Meter will output net energy
Reactive Energy (Q) Measured in volt-amperes reactive
(VARh or kVARh)
Apparent Energy (S) Measured in volt-amperes (VAh or kVAh)
1Total Real ‘Active Energy outputs both import and export pulses as the
energy is accumulated by the meter.
2Net Real ‘Active’Energy sums the channels internally before outputting, so
import and export energy will cancel, resulting in the net energy output.
Setting 4. Balanced Load Multiplier
The Balanced Load Multiplier is utilized so that one CVT can
extrapolate power of a balanced load (e.g. motor) without
actually monitoring all 3 phases. The multiplier can be applied
to one or more CVT channels, meaning the EM-PULSE can
monitor up to three motors with one meter:
Setting Balanced Load Multiplier Function
Disable all balanced
load multiplers - Default All balanced load multipliers are disabled
Enable R balanced load
multiplier Output for R channel = 3X power measurement
Enable S balanced load
multiplier Output for S channel = 3X power measurement
Enable RS balanced
load multipliers Output for R & S channels = 3X power measurement
Enable T balanced load
multiplier Output for T channel = 3X power measurement
Enable RT balanced
load multipliers Output for R & T channels = 3X power measurement
Enable ST balanced
load multipliers Output for S & T channels = 3X power measurement
Enable RST balanced
load multipliers Output for all channels = 3X power measurement
Setting 5. PowerPrint
PowerPrint is a power quality alarm that enables the meter to
learn and save characteristics of the system being monitored.
Based on recorded values, the meter can provide alarm
conditions and allow user to evaluate system status at a later
time. This is an optional feature, but as PowerPrint is turned
on, the meter identies each CVT connection and saves
settings on the following parameters:
1. Which channels have a CVT connected
2. Amperage rating and internal serial number of each CVT
3. System voltage
4. System frequency
5. Phase voltage angle
