1.1 About This Manual
This manual is intended for the user of the PM130 Powermeter.
The PM130 is a microprocessor-based instrument used for measurement, monitoring, and management of electrical parameters.
This chapter gives an overview of this manual and an introduction
to the PM130.
Chapter 2, Installation, provides instructions for mechanical and
electrical installation.
Chapter 3, Using the Menus, presents the structure of menus for
setup and status viewing.
Chapter 4, Setup Menus, provides instructions for performing
parameter setup via the front panel.
Chapter 5, Data Display, guides you through the display pages.
Chapter 6, Viewing Status Information, tells you how to access
additional status information on the instrument. This information
may be useful during installation.
Technical Specifications for the PM130 are found in the Appendix.
1.2 About The PM130
The PM130 is a compact panel mounted 3-phase AC Powermeter,
specially designed to meet the requirements of users ranging from
electrical panel builders to substation operators. The PM130 is
available in three models: the PM130 for basic voltage, current
and frequency measurements; the PM130P which adds power and
power factor measurements; and the PM130E which adds power
demands and energy measurements. All models are suitable for
mounting on both 4-inch round and 92x92mm square cut-outs.
Features
Display: The front panel features bright LED displays (three
windows, up to 38 pages) with adjustable display update time, and
a LED bar graph showing percentage load with respect to userdefinable nominal (100%) load current. In the common
measurements group (see Chapter 5), Display Auto Scroll is
available with a programmable scroll interval of 2 to 15 seconds.
Chapter 1 Introduction
2
Automatic return to the main screen is available after 30 seconds
of uninterrupted use.
Setup is menu driven, with optional password protection.
Communications are available using an RS-485 standard, with
ASCII/Modbus or ASCII/DNP3.0 protocols. 120 user assignable
registers are available. Transmitter and receiver status are
displayed on the status information page (see Chapter 6).
One multi-purpose relay (optional) is provided for energy pulsing
(KYZ) or alarm and remote control. Up to 16 setpoints can be
assigned to the relay.
Four time operation counters are provided which are operated
and released by user-defined triggers. These are for counting total
generator time or transformer or power line time overload.
External synchronization of the power demand interval is
provided through communications in the PM130E.
Three user-selectable options are provided:
Power calculation mode (P.cAL):
Mode 1: Reactive power calculation (rEAc)
Active power P and reactive power Q are measured
directly and apparent power S = √ P
2
+ Q2
Mode 2: Non-active power calculation (nAct)
Active power is measured directly, and apparent
power S = V × I (V, I - rms voltage and currents)
and non-active power N = √ S
2 - P2
Mode 1 is recommended for electrical networks with low
harmonic distortion (voltage THD < 5%, current THD < 10%);
Mode 2 is recommended for all other cases. (
The PM130 does
not measure harmonics; contact your distributor for information on
instruments that provide harmonic measurement).
Energy rollover value (roll – PM130E only)
This option specifies the point at which the energy value rolls
over to zero. For example, if the roll value is 10.E4, then the
energy counter has 4 digits, i.e., energy is displayed up to 9999
kWh (kvarh, kVAh) with resolution 1 kW-hour.
Roll value Maximum Energy Resolution
10.E4 9999 kWh (kvarh, kVAh) 1 kWh (kvarh, kVAh)
10.E5 99999 kWh (kvarh, kVAh) 1 kWh (kvarh, kVAh)
10.E6 999.99 MWh (kvarh, kVAh) 10 kWh (kvarh, kVAh)
10.E7 9999.9 MWh (kvarh, kVAh) 100 kWh (kvarh, kVAh)
10.E8 99999. MWh (Mvarh, MVAh) 1 MWh (Mvarh, MVAh)
Chapter 1 Introduction 3
The roll value may be changed in accordance with the average
load of the power line. For example, if average power equals 400
kW and the counter must reset every 3 months (2160 hours),
then energy during this period equals 864000 (6 digits) and the
roll = 10.E6.
Phase energy calculations mode (Ph.En)
This option is used to enable or disable phase energy calculations.

2.2 Electrical Installation
) Before installation ensure that all incoming power
sources are shut OFF. Failure to observe this practice can
result in serious or even fatal injury and damage to
equipment.
Connections to the PM130 are made via terminals (voltage input,
power supply, communication and optional relay output) and CT
cores located on the rear of the instrument as shown in Figure 2-3.
Note: If your PM130 was not ordered with the optional relay, it will
not have the relay connector.
Figure 2-3 PM130 Connections - Rear View
2.2.1 Power Supply Connection
The power supply can be dedicated-fused, or from a monitored
voltage if it is within the instrument’s power supply range.
Connection to the AC power supply is: Line to terminal L; Neutral
to terminal N.
Chapter 2 Installation 9
2.2.2 Current Inputs
To ensure accurate readings, the input current should not exceed
1.5A RMS for the 1A CT secondary, or 7.5A RMS for the 5A CT
secondary.
The PM130 does not have current terminals. To connect to the
external CT, you must pass the external CT wire through the
instrument CT core (see Figure 2-4).
In the case of a retrofit where each external CT ends with two
wires, pass one wire through the core and connect it to one of the
instrument termination screws; connect the second wire from the
termination screw to the external CT to close the loop. One wire
must pass through the core; observe the arrow which indicates
the current direction (see Figure 2-4).

4.4 Alarm/Event Setpoints Setup Menu
Your instrument provides 16 alarm/event setpoints that can
monitor a wide variety of events; in turn, these events can be
programmed to trigger specific actions. This menu is used to
specify the events to be monitored by the setpoints, and actions to
be triggered by those events.
To program a setpoint (all 16 can be assigned to the relay) you
need to define up to six setup parameters: the setpoint trigger
parameter, operate and release limits, optional operate and
release delays, and the setpoint action. Tables 4-4, 4-5 and 4-6 list
the setpoint setup parameters, available triggers and setpoint
actions.
Example:
Trigger
parameter
Setpoint 1 is set to monitor the real-time
high current on phase 1 (the trigger
parameter).
Operate limit }
}
}
}
Release limit }
The operate (On) and release (OFF)
limits which determine setpoint
operation are defined as 1200A and
1100A respectively.
Operate delay }
}
}
Release delay
}
The delays before operation (On d)
and release (OFFd) are set at 5
seconds and 10 seconds respectively.
Setpoint action
The action to be triggered is relay
operation.
To select a setpoint:
Scroll to the desired setpoint using the up/down arrow keys.

When a setpoint is operated, its status is always stored to the alarm status
register even if no action is assigned to the setpoint. The alarm status can
be inspected and cleared from the front panel through the Status
Information Menu (see Section 6.2) or via communications.
This action converts a common event counter to the time counter which
measures time at 0.1 hour resolution while the setpoint is in the operated
state. Each time counter has a non-volatile shadow counter which counts
time at 1 second resolution before the corresponding time counter is
incremented. Time counters can be inspected via the Status Information
Menu. They are labeled by

4.5 Relay Operation Control Menu
This menu allows you to set the relay operation mode: non-failsafe
or failsafe. Failsafe relay operation is the opposite of normal
operation where relay contacts are closed when a relay is
operated (activated), and are open when a relay is released (deactivated). In failsafe mode, an alarm is activated by a nonenergized relay which will open in all cases when an alarm
condition is present or an alarm setpoint is not operational either
due to a loss of control power or due to corruption of the setpoint
setup configuration. A failsafe relay is closed only if it is under
setpoint control and no alarm conditions exist, or if it is manually
operated via communications.
To change the relay operation mode:
Press to activate the lower window.
Use the up/down arrow keys to set the desired
option. Select nor for normal (non-failsafe) relay
operation, or select FSAFE for failsafe relay
operation.
Press to store your new setting or press to
leave your previous setting unchanged.
To quit the setup menu:
From the middle window, press or .
NOTES
1. You will not be able to change the relay operation mode if a relay has
been allocated for pulsing.
2. When a failsafe relay is allocated for pulsing, it automatically reverts
to normal operation.

5.1 Navigating in the Display Mode
The front panel has a simple interface that allows you to display
numerous measurement parameters in up to 38 display pages. For
easier reading, the parameters are divided into three groups, each
accessible by a designated key. These are:
Common measurements
- no selection key
Min/Max measurements
- selected by the key
Energy measurements
- selected by the key
The up/down arrow keys are used as follows in the Display Mode:
Scrolls through the pages downward (forward)
Scrolls through the pages upward (backward)
Returns to the first page within current measurement group
For each display page, up to three parameters can be displayed.
The Load bar graph displays the amount, in percent, of the current
load with respect to user-defined nominal load current. The highest
current measured by the PM130 is divided by the nominal load
current as defined in the Display Setup Menu (see Section 4.6)
and expressed as a percent by the LEDs (40% to 110%) which are
lit. For example, if all LEDs up to and including 90% are lit, this
means that the load is 90%-100% of the nominal load current. If
the nominal load current is set to 0, the CT primary current setup is
used.

Display readings for all electrical quantities except Min/Max log and
energies are sliding average values.
Voltage and current readings with a decimal point are displayed in kV and
kA. Power readings with a decimal point are displayed in MW, Mvar, and
MVA. When the value width is over the window resolution, the right most
digits are truncated.
By default, the maximum range for energy readings is 99,999,999
MWh/Mvarh/MVAh. Beyond this value, the reading will roll over to zero.
When the energy reading exceeds the window resolution, the right-most
digits are truncated. To avoid truncation, you can change the energy roll
value to lower limit via the User Selectable Options menu (see Section
4.7). Negative (exported) energy readings are displayed without a sign.
Per phase power and power factor readings are displayed only in
4LN3/4LL3 and 3LN3/3LL3 wiring modes (see Section 4.1) if the phase
powers display is enabled in the Display Setup menu (see Section 4.6).
Phase energy readings are displayed only in 4LN3/4LL3 and 3LN3/3LL3
wiring modes if they are enabled in the User Selectable Options menu (see
Section 4.7).
When the 4LN3 or 3LN3 wiring mode is selected, the voltages will be line-
to-neutral; for any other wiring mode, they will be line-to-line voltages.
Displayed only in the 4LN3 or 3LN3 wiring mode.
5.3 Self-Test Diagnostics Display
The PM130 periodically performs self-test diagnostics during
operation. If the instrument fails the test, it discards the last
measurement results, and an error code is displayed for one
second on all LEDs. Error codes are listed in Table 5-3. Code ‘8’
indicates normal operation.
available in the PM130E
E
Chapter 5 Data Display
40
Frequent failures may be the result of excessive electrical noise in
the region of the instrument. If the instrument continuously resets
itself, contact your local distributor.
Table 5-3 Self-Test Diagnostic Codes
Code Meaning
1 ROM error
2 RAM error
3 Watch dog timer reset
4 Sampling failure
5 Out of control trap
7 Timing failure
8 Normal power up
9 External reset (warm restart)
NOTE
The PM130 provides a self-check alarm register accessible through
communications that indicates possible problems with instrument
hardware or setup configuration. The hardware problems are indicated
by the appropriate bits which are set whenever the instrument fails selftest diagnostics or in the event of loss of power. The setup
problems are
indicated by the dedicated bit which is set when either configuration
register is corrupted. In this event, your instrument will use the default
configuration. For more information on the self-check alarm register, refer
to the communications reference guides provided with your instrument.

Key:
PT = external potential transformer ratio CT, CT Primary Current = primary current rating of external current transformer
FSU = voltage full scale
FSI = current full scale
@ 10% to 120% of voltage FS and 2% to 150% of current FS
Higher resolution is achievable via communications
Where the current is > 10% FS, the energy accuracy is better than 1.5% Rdg.
Additional Notes
1. Accuracy is expressed as ± (percentage of reading + percentage of full scale) ± 1 digit. This does not include
inaccuracies introduced by the user's potential and current transformers.
2. Specifications assume a reference temperature of 20 - 26
°C.
3. Specifications for kvar, kVA and PF assume voltage and current waveforms with THD
≤ 5%
4. Ordinary measurement error is considerably less than the specified accuracy which indicates maximum error.
