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 off - 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

PowerPrint will not monitor frequency variance if system frequency is not
50 or 60Hz when PowerPrint is initiated.
PowerPrint Diagnostic Codes

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)
1
Total Real ‘Active Energy outputs both import and export pulses as the
energy is accumulated by the meter.
2
Net 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 identifies 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
