The circuit monitor is a multifunction, digital instrumentation, data acquisition and control device. It can replace a variety of meters, relays, transducers and other components. The circuit monitor can be located at the service entrance to monitor the cost and quality of power, and can be used to evaluate the utility service. When located at equipment mains, the circuit monitor can detect voltage-based disturbances that cause costly equipment downtime.
The circuit monitor is equipped with
RS-485 and RS-232 communications for
integration into any power monitoring and control system. However, System Managersoftware (
SMS)fromPOWERLOGIC, which is written specifically
for power monitoring and control, best supports the circuit monitor’s advanced features.
The circuit monitor is a true rms meter capable of exceptionally accurate measurement of highly nonlinear loads. A sophisticated sampling technique enables accurate, true rms measurement through the 255th harmonic. You can view over 50 metered values plus extensive minimum and maximum data from the display or remotely using software. Table 1–1 summarizes the readings available from the circuit monitor.

63230-300-212 Chapter 1—Introduction April 2 001 What is the Circuit Monitor?

Accessories and Options for the Circuit Monitor

The circuit monitor has a modular design to maximize its usability. In addition to the main meter, the circuit monitor has plug-on modules and accessories, including:
• Current/voltage module (CVM). A standard part of the circuit monitor is
the current/voltage module where all metering data acquisition occurs.
• Remote display . The optional remote 4-line display is available with a
back-lit liquid crystal display (LCD) or a vacuum fluorescent display (VFD). The VFD model includes an infrared port that can be used to communicate directly with the circuit monitor from a laptop and can be used to download firmware, which keeps the circuit monitor up to date with the latest system enhancements.
I/O Extender. The I/O extender, located on the side of the circuit monitor,
enables you to plug inup to 8 industry-standard inputs and outputs. Several preconfigured combinations are available, or you can create a custom configuration.
Digital I/O Card. You can further expand the I/O capabilities of the circuit
monitor by adding a digital I/O card (4 inputs and 4 outputs). This card fits into one of the option slots on the top of the circuit monitor.
Ethernet Communications Card. The Ethernet communications card
provides an Ethernet port that accepts a 100 Mbps fiber optic cable or a 10/100 Mbps UTP and provides an RS-485 master port to extend the circuit monitor communications options. This card is easily installed into option slot A on the top of the circuit monitor.
Table 1–2 lists the circuit monitor parts and accessories and their associated instruction bulletins.

Setting Up Alarms

This section describes how to setup alarms and create your own custom alarms. For a detailed description of alarm capabilities, see Chapter 6— Alarms on page 83. The circuit monitor can detect over 100 alarm conditions, including over/under conditions, status input changes, phase unbalance conditions, and more. Some alarms are preconfigured and enabled at the factory. See Factory Defaultson page 11 in Chapter 3— Getting Started of the installation manual for information about preconfigured alarms. You can edit the parameters of any preconfigured alarm from the display.
For each alarm that you set up, do the following:
Select the alarm group that defines the type of alarm:
Standard speed
alarms have a detection rate of one second and are useful for detecting conditions such as over current and under voltage. Up to 80 alarms can be set up in this group.
High speed
alarms have a detection rate of 100 milliseconds and are useful for detecting voltage sags and swells that last a few cycles. Up to 20 alarms can be set up in this group.
Disturbance monitoring
alarms have a detection rate of one cycle and are useful for detecting voltage sags and swells. Up to 20 alarms can be set up in this group.
Digital
alarms are triggered by an exception such as the transition of a status input or the end of an incremental energy interval. Up to 40 alarms can be set up in this group.
Boolean
alarms have a detection rate of the alarms used as inputs. They are used to combine specific alarms into summary alarm information.
Select the alarm that you want to configure. Keep the default name or enter a new name with up to 15 characters.
Enable the alarm.
Assign a priority to the alarm. Refer to “Viewing Alarms” on page 41 for
information about the alarm priority levels.
Define any required pickup and dropout setpoints, and pickup and dropout time delays (for standard, high speed, and disturbance alarm groups only, refer to Setpoint-Driven Alarmson page 85 in Chapter 6—Alarms).

Advanced Setup Features

Creating Custom Quantities to be Displayed
The features discussed in this section are not required for basic circuit monitor setup, but can be used to customize your circuit monitor to suit your needs.
Any quantity that is stored in a register in the circuit monitor can be displayed on the remote display. The circuit monitor has a list of viewable quantities already defined such as average current, power factor total, and so forth. In addition to these predefined values, you can define custom quantities that can be displayed on a custom screen. For example, if your facility uses different types of utility services such as water, gas, and steam, you may want to track usage of the three services on oneconvenient screen. To dothis, you could set up inputs to receive pulses from each utility meter, then display the scaled register quantity.
For the circuit monitor display, custom quantities can be used to display a value. Dont confuse this feature with quantities are used to add new parameters which functions. new into
SMS custom quantities are defined, for example, when you add a
POWERLOGIC-compatible device to SMS or if you want to import data
SMS from another software package. You can use the SMS custom

Figure 3–10: Wiring Error Test option on the Diagnostics menu.
The circuit monitor can diagnose possible wiring errors when you initiate the wiring test on the Diagnostics menu. Running the test is not required, but may help you to pinpoint a potentially miswired connection. Before running the wiring test, you must first wire the circuit monitor and perform the minimum set up of the circuit monitor, which includes setting up these parameters:

CT primary and secondary
PT primary and secondary
System type
Frequency
After you have wired and completed the minimum set up, run the wiring test to verify proper wiring of your circuit monitor. The wiring test assumes that the following is true about your system:
45
Page 58
Chapter 3Operation 63230-300-212 Performing a Wiring Check April 2001
Voltage connection Van(4-wire) or Vab(3-wire) is correct. This connection must be properly wired for the wiring check program to work.
3-phase system. The system must be a 3-phase system. You cannot perform a wiring check on a single-phase system.
System type. The wiring check can be performed only on the six possible system types: 33W2CT, 33W3CT, 34W3CT, 34W4CT, 34W3CT2PT, and 34W4CT2PT (see Table 5–2 on page 38 of the installation manual for a description of system types).
Expected displacement power factor is between .60 lagging and .99 leading.
The load must be at least 1% of the CT Primary setting.
This wiring error program is based on the assumptions above and based on a typical wiring system, results may vary depending on your system and some errors may not apply to your system. When the wiring test is run, the program performs the following checks in this order:
1. Verifies that the system type is one of those listed above.
2. Verifies that the frequency is within ±5% of the frequency that you
selected in circuit monitor set up.
3. Verifies that the voltage phase angles are 120° apart. If the voltage
connections are correct, the phase angles will be 120° apart. If the voltage connections are correct, the test continues.
4. Verifies that the measured phase rotation is the same as the phase
rotation set up in the circuit monitor.
5. Verifies the magnitude of the currents to see if there is enough load on
each phase input to perform the check.
6. Indicates if the 3-phase real power (kW) total is negative, which could
indicate a possible wiring error.
7. Compares each current angle to its respective voltage.

MIN/MAX VALUES FOR REAL-TIME READINGS

© 2001 Schneider Electric All Rights Reserved
When any one-second real-time reading reaches its highest or lowest value, the circuit monitor saves the value in its nonvolatile memory. These values are called the minimum and maximum (min/max) values. Two logs are associated with min/max values. The Min/Max Log stores the minimum and maximum values since the last reset of the min/max values. The other log, the Interval Min/Max/Average Log, determines min/max values over a specified interval and records the minimum, maximum, and average values for pre-defined quantities over that specified interval. For example, the circuit monitor could record the min, max, and average every 1440 minutes (total minutes in a day) to record the daily value of quantities such as kW demand. See Chapter 7Logging on page 99 for more about the Min/Max/Average log.
From the circuit monitor display you can:
View all min/max values since the last reset and view their associated dates and times. See Viewing Minimum and Maximum Values from the Min/Max Menuon page 39 for instructions.
Resetmin/maxvalues.SeeResetting Min/Max, Demand, and Energy Values” on page 37 for reset instructions.

Power Factor Min/Max Conventions

All running min/max values, except for power factor, are arithmetic minimum and maximum values. For example, the minimum phase A–Bvoltageisthe lowest value in the range 0 to 1200 kV that has occurred since the min/max values were last reset. In contrast, because the power factor’s midpoint is unity (equal to one), the power factor min/max values are not true arithmetic minimums and maximums. Instead, the minimum value represents the measurement closest to –0 on a continuous scale for all real-time readings –0 to 1.00 to +0. The maximum value is the measurement closest to+0onthesamescale.
Figure 4–1 below shows the min/max values in a typical environment in which a positive power flow is assumed. In the figure, the minimum power fact or is –.7 (lagging) and the maximum is .8 (leading). Note that the minimum power factor need not be lagging, and the maximum power factor need not be leading. For example, if the power factor values ranged from –.75 to –.95, then the minimum power factor would be –.75 (lagging) and the maximum power factor would be –.95 (lagging). Both would be negative. Likewise, if the power factor ranged from +.9 to +.95, the minimum would be +.95 (leading) and the maximum would be +.90 (leading). Both would be positive in this case.

Demand Power Calculation Methods

Block Interval Demand
Demand power is the energy accumulated during a specified period divided by the length of that period. How the circuit monitor performs this calculation depends on the method you select. To be compatible with electric utility billing practices, the circuit monitor provides the following types of demand power calculations:
Block Interval Demand
Synchronized Demand
The default demand calculation is set to sliding block with a 15 minute interval. You can set up any of the demand power calculation methods from the display or from
SMS. For instructions on how to setup the demand
calculation from the display, see Setting Up the Metering Functions of the Circuit Monitoron page 16. See the
SMS online help to perform the set up
using the software.
In the block interval demand method, you select a blockof time that the circuit monitor uses for the demand calculation. You choose how the circuit monitor handles that block of time (interval). Three different modes are possible:
Sliding Block. In the sliding block interval, you select an interval from 1 to 60 minutes (in 1-minute increments). If the interval is between 1 and 15 minutes, the demand calculation is between 16 and 60 minutes, the demand calculation

.Iftheinterval
completed interval.
Fixed Block. In the fixed block interval, you select an interval from 1 to 60 minutes (in 1-minute increments). The circuit monitor calculates and updates the demand at the end of each interval.
Rolling Block. In the rolling block interval, you select an interval and a subinterval. The subinterval must divide evenly into the interval. For example, you might set three 5-minute subintervals for a 15-minute interval. Demand is
updated at each subinterval
. The circuit monitor
displays the demand value for the last completed interval.

63230-300-212 Chapter 4Metering Capabilities April 2 001 Demand Readings
Synchronized Demand
The demand calculations can be synchronized by accepting an external pulse input, a command sent over communications, or by synchronizing to the internal real-time clock.
Input Synchronized Demand. You can set up the circuit monitor to accept an input such as a demand synch pulse from an external source. The circuit monitor then uses the same time interval as the other meter for each demand calculation. You can use any digital input installed on the meter to receive the synch pulse. When setting up this type of demand, you select whether it will be input-synchronized block or input­synchronized rolling block demand. The rolling block demand requires that you choose a subinterval.
Command Synchronized Demand. Using command synchronized demand, you can synchronize the demand intervals of multiple meters on a communications network. For example, if a PLC input is monitoring a pulse at the end of a demand interval on a utility revenue meter, you could program the PLC to issue a command to multiple meters whenever the utility meter starts a new demand interval. Each time the command is issued, the demand readings of each meter are calculated for the same interval. When setting up this type of demand, you select whether it will be command-synchronized block or command-synchronized rolling block demand. The rolling block demandrequires that you choose a subinterval. See Appendix BUsing the Command Interface on page 181 for more information.
Clock SynchronizedDemand. You can synchronize the demand interval to the internal real-time clock in the circuit monitor. This enables you to synchronize the demand to a particular time, typically on the hour. The default time is 12:00 am. If you select another time of day when the demand intervals are to be synchronized, the time must be in minutes from midnight. For example, to synchronize at 8:00 am, select 480 minutes. When setting up this type of demand, you select whether it will be clock-synchronized block or clock-synchronized rolling block demand. The rolling block demand requires that you choose a subinterval.

Thermal Demand

Predicted Demand

The thermal demand method calculates the demand based on a thermal response, which mimics thermal demand meters. The demand calculation updates at the end of each interval. You select the demand interval from 1 to 60 minutes (in 1-minute increments). In Figure 4–4 the interval is set to 15 minutes for illustration purposes.

Peak Demand

Generic Demand

In nonvolatile memory, the circuit monitor maintains a running maximum for power demand values, called peak demand.The peak is the highest average for each of these readings: kWD, kVARD, and kVAD since the last reset. The circuit monitor also stores the date and time when the peak demand occurred. In addition to the peak demand, the circuit monitor also stores the coinciding average 3-phase power factor. The average 3-phase power factor is defined as demand kW/demand kVAfor the peak demand interval. Table 4–3 on page 56 lists the available peak demand readings from the circuit monitor.
You can reset peak demand values from the circuit monitor display. From the Main Menu, select Resets > Demand. You can also reset the values over the communications link by using
SMS.SeetheSMS online help for instructions.
NOTE: You should reset peak demand after changes to basic meter setup, such as CT ratio or system type.
The circuit monitor also stores the peak demand during the last incremental energy interval. See Energy Readingson page 64 for more about incremental energy readings.
The circuit monitor can perform any of the demand calculation methods, described earlier in this chapter, on up to 20 quantities that you choose. In
SMS the quantities are divided into two groups of 10, so you can set up two
different demand profiles.For each profile, you do the following in
SMS:
Select the demand calculation method (thermal, block interval, or synchronized).
Select the demandinterval (from 5–60 minutes in 1–minute increments) and select the demand subinterval (if applicable).
Select the quantities on which to perform the demand calculation. You must also select the units and scale factor for each quantity.
Use the Device Setup > Basic Setup tab in
SMS to create the generic
demand profiles. For example, you might set up a profile to calculate the 15-minute average value of an analog input. To do this, select a fixed-block demand interval with a 15-minute interval for the analog input.
For each quantity in the demand profile, the circuit monitor stores four values:
Partial interval demand value
Last completed demand interval value
Minimum values (date and time for each is also stored)
Peak demand value (date and time for each is also stored)
You can reset the minimum and peak values of the quantities in a generic demand profile by using one of two methods:
Use
SMS (see the SMS online help file), or
Use the command interface. Command 5115 resets the generic demand profile 1. Command 5116 resets the generic demand profile 2. See Appendix BUsing the Command Interface on page 181 for more about the command interface.

Input Pulse Demand Metering

The circuit monitor has ten input pulse metering channels. The channels count pulses received from one or more digital inputs assigned to that channel. Each channel requires a consumption pulse weight, consumption scale factor, demand pulse weight, and demand scale factor. The consumption pulse weight is the number of watt-hours or kilowatt-hours per pulse. The consumption scale factor is a factor of 10 multiplier that determines the format of the value. For example, if each incoming pulse represents 125 Wh, and you want consumption data in watt-hours, the consumption pulse weight is 125 and the consumption scale factor is zero. The resulting calculation is 125 x 10
0
, which equals 125 watt-hoursper pulse.
If you want the consumption data in kilowatt-hours, the calculation is 125 x
-3
10
, which equals 0.125 kilowatt-hours per pulse.
Time must be taken into account for demand data so you begin by calculating demand pulse weight using the following formula:
watts =
watt-hours x 3600 seconds x pulse
per pulse per hour per second
If each incoming pulse represents 125 Wh, using the formula above you get 450,000 watts. If you want demand data in watts, the demand pulse weight is 450 and the demand scale factor is three. The calculation is 450 x 10
3
, which equals 450,000 watts. If you want the demand data in kilowatts, the calculation is 450 x 10
0
, which equals 450 kilowatts.
The circuit monitor counts each input transition as a pulse. Therefore, for an input transition of OFF-to-ON and ON-to-OFF will be counted as two pulses. For each channel, the circuit monitor maintains the following information:
Total consumption
Last completed interval demand—calculated demand for the last
completed interval.
Partial interval demanddemand calculation up to the present point
during the interval.
Peak demandhighest demand value since the last reset of the input
pulse demand. The date and time of the peak demand is also saved.
Minimum demandlowest demand value since the last reset of the input
pulse demand. The date and time of the minimum demand is also saved.
For example, you can use channels to verify utility charges. In Figure 4–6, Channel 1 is adding demand from two utility feeders to track total consumption and demand for the building. This information could be viewed in
SMS and compared against the utility charges.
To use the channels feature, first set up the digital inputs from the display or from
SMS.SeeSettingUpI/Os” on page 23 in Chapter 3Operation for
instructions. Then using
SMS, you must set the I/O operating mode to Normal
and set up the channels. The demand method and interval that you select applies to all channels. See the
SMS online help for instructions on device set
up of the CM4000 Circuit Monitor.

The circuit monitor can accumulate the energy values shown in Table 4–4in one of two modes: signed or unsigned (absolute). In signed mode, the circuit monitor considers the direction of power flow, allowing the magnitude of accumulated energy to increase and decrease. In unsigned mode, the circuit monitor accumulates energy as a positive value, regardless of the direction of power flow. In other words, the energy value increases, even during reverse power flow. The default accumulation mode is unsigned.
You can view accumulated energy from the display. The resolution of the energy value will automatically change through the range of 000.000 kWh to 000,000 MWh (000.000 to 000,000 MVARh), or it can be fixed. See Appendix AAbbreviated Register Listing on page 127 for the contents of the registers.

63230-300-212 Chapter 4Metering Capabilities April 2 001 Energy Readings
For conditional accumulated energy readings, you can set the real, reactive, and apparent energy accumulation to
OFF or ON when a particular condition
occurs. You can do this over the communications link, using a command, or from a digital input change. For example, you may want to track accumulated energy values during a particular process that is controlled by a PLC. The circuit monitor stores the date and time of the last reset of conditional energy in nonvolatile memory.
Also, the circuit monitor provides an additional energy reading that is only available over the communications link:
Four-quadrant r eactive accumulated energy readings. The circuit
monitor accumulates reactive energy (kVARh) in four quadrants as shown in Figure 4–7. The registers operate in unsigned (absolute) mode in which the circuit monitor accumulates energy as positive.

POWER ANALYSIS VALUES

The circuit monitor provides a number of power analysis values that can be used to detect power quality problems, diagnose wiring problems, and more. Ta b le 4 –5 on page 68 summarizes the power analysis values.
THD. Total Harmonic Distortion (THD) is a quick measure of the total
distortion present in a waveform and is the ratio of harmonic content to the fundamental. It provides a general indication of the qualityof a waveform. THD is calculated for both voltage and current. The circuit monitor uses the following equation to calculate THD where H is the harmonic distortion:

Displacement PowerFactor. Power factor (PF) represents the degree to
which voltage and current coming into a load are out of phase. When true power factor is based on the angle between the fundamental components of current and voltage.
Harmonic Values. Harmonics can reduce the capacity of the power
system. The circuit monitor determines the individual per-phase harmonic magnitudes and angles through the 63rd harmonic for all currents and voltages. The harmonic magnitudes can be formatted as either a percentage of the fundamental (default) or a percentage of the rms value. Refer to Setting Up Individual Harmonic Calculationson page 190 in

63230-300-212 Chapter 5Input/Output Capabilities April 2 001 Digital Inputs

DIGITAL INPUTS

The circuit monitor can accept up to 16 digital inputs depending on the I/O accessories you select. Digital inputs are used to detect digital signals. For example, the digital input can be used to determine circuit breaker status, count pulses, or count motor starts. Digital inputs canalso be associated with an external relay, which can trigger a waveform capture in the circuit monitor. You can log digital input transitions as events in the circuit monitors on-board alarm Log. The event is date and time stamped with resolution to the millisecond, for sequence of events recording. The circuit monitor counts
OFF-to-ON transitions for each input, and you can reset this value using the
command interface.
Digital inputs have four operating modes:
Normal—Use the normal mode for simple on/off digital inputs. In normal
mode, digital inputs can be used to count KYZ pulses for demand and energy calculation. Using the input pulse demand feature, you can map multiple inputs to the same channel where the circuit monitor can total pulses from multiple inputs (seeInput Pulse Demand Meteringon page 62 in Chapter 4Metering Capabilities for more information). To accurately count pulses, set the time between transitions from
OFF to ON
and ON to OFF to at least 20 milliseconds.
Demand Interval Synch Pul seyou can configure any digital input to
accept a demand synch pulse from a utility demand meter (see Demand Synch Pulse Inputon page 72 of this chapter for more about this topic). For each demand profile, you can designate only one input as a demand synch input.
Time Synchyou can configure one digital input to receive a signal from
a GPS receiver that provides a serial pulse stream in accordance to the DCF-77 format to synchronize the internal clock of the circuit monitor.
Conditional Energy Controlyou can configure one digital input to control conditional energy (see “Energy Readingson page 64 in Chapter 4Metering Capabilities for more about conditional energy).
© 2001 Schneider Electric All Rights Reserved
To set up a digital input on the I/O extender, you must first define it from the display. From the main menu, select Setup > I/O. Select the appropriate digital input option. For example, if you are using IOX-2411 option of the I/O Extender, select IOX-2411. For detailed instructions, see Setting Up I/Oson page 23 in Chapter 3Operation. Then using SMS, define the name and operating mode of the digital input. The name is a 16-character label that identifies the digital input. The operating mode is one of those listed above. See the SMS online help for instructions on device set up of the circuit monitor.

Chapter 5Input/Output Capabilities 63230-300-212 Demand Synch Pulse Input April 2001

DEMAND SYNCH PULSE INPUT

You can configure the circuit monitor to accept a demand synch pulse from an external source such as another demand meter. By accepting demand synch pulses through a digital input, the circuit monitor can make its demand interval windowmatch the other meter’s demand interval window.The circuit monitor does this by watchingthe digital input for a pulse from the other demand meter. When it sees a pulse, it starts a new demand interval and calculates the demand for the preceding interval. The circuit monitor then uses the same time interval as the other meter for each demand calculation. Figure 5–1 illustrates this point. See Synchronized Demandon page 59 in Chapter 4Metering Capabilities for more about demand calculations.
When in demand synch pulse operating mode, the circuit monitor will not start or stop a demand interval without a pulse. The maximum allowable time between pulses is 60 minutes. If 66 minutes (110% of the demand interval) pass before a synch pulse is received, the circuit monitor throws out the demand calculations and begins a new calculation when the next pulse is received. Once in synch with the billingmeter, the circuit monitor can be used to verify peak demand charges.
Important facts about the circuit monitor’s demand synch feature are listed below:
Any installed digital input can be set to accept a demand synch pulse.
Each system can choose whether to use an external synch pulse, but only
one demand synch pulse can be brought into the meter for each demand system. One input can be used to synchronize any combination of the demand systems.
The demand synch feature can be set up from
SMS. See the SMS online
help for instructions on device set up of the circuit monitor.

ANALOG INPUTS

Depending on the I/O modules you select, the circuit monitor can accept either voltage or current signals through its analog inputs. See Table 5–1on page 70 for a list of I/O options. The circuit monitor stores a minimum and a maximum value for each analog input.
For technical specifications and instructions on installing I/O modules, refer to the instruction bulletin that ships with the I/O (see Table 1–2onpage3for a list of these publications). To set up analog inputs, you must first set it up from the display. From the main menu, select Setup > I/O, then select the appropriate analog input option. For example, if you are using the
IOX0404
option of the I/O Extender, select IOX-0404. For detailed instructions, see SettingUpI/Os” on page 23 in Chapter 3Operation. Then, in
SMS define
the following values for each analog input:
Namea 16-character label used to identify the analog input.
Unitsthe units of the monitored analog value (for example, “psi”).
Scale factormultiplies the units by this value (such as tenths or
hundreths).
Report Range Lower Limitthe value the circuit monitor reports when the input reaches a minimum value. When the input current is below the lowest valid reading, the circuit monitor reports the lower limit.
Report Range Upper Limitthe value the circuit monitor reports when the input reaches the maximum value. When the input current is above highest valid reading, the circuit monitor reports the upper limit.

RELAY OUTPUT OPERATING MODES

Before we describe the 11 available relay operating modes, it is important to understand the difference between a relay configured for remote (external) control and a relay configured for circuit monitor (internal) control.
Each relay output defaults to external control, but you can choose whether the relay is set to external or internal control:
Remote (external)controlthe relay is controlled either from a
SMS or a programmable logic controller using commands via
PC using
communications.
Circuit monitor (internal) control—the relay is controlled by the circuit monitor in response to a set-point controlled alarm condition, or as a pulse initiator output. Once you’ve set up a relay for circuit monitor control, you can no longer operate the relay remotely. However, you can temporarily override the relay, using
SMS.
NOTE: If any basic setup parameters or I/O setup parameters are modified, all relay outputs will be de-energized.
The 11 relay operating modes are as follows:
Normal
Remotely Controlled:
a remote
PC or programmable controller. The relay remains energized
until a command to de-energize is issued from the remote
Energize the relay by issuing a command from
PC or
programmable controller, or until the circuit monitor loses control power. When control power is restored, the relay will be re-energized.
Circuit Monitor Controlled:
When an alarm condition assigned to the
relay occurs, the relay is energized. The relay is not de-energized until
all
alarm conditions assigned to the relay have dropped out, the circuit monitor loses control power, or the alarms are over-ridden using SMS software. If the alarm condition is still true when the circuit monitor regains control power, the relay will be re-energized.
Latched
Remotely Controlled:
a remote
PC or programmable controller. The relay remains energized
until a command to de-energize is issued from a remote
Energize the relay by issuing a command from
PC or
programmable controller, or until the circuit monitor loses control power. When control power is restored, the relay will not be re­energized.
Circuit Monitor Controlled:
When an alarm condition assigned to the relay occurs, the relay is energized. The relay remains energized even after all alarm conditions assigned to the relay have dropped outuntil a command to de-energize is issued from a remote PC or programmable controller, until the high priority alarm log is cleared from the display, or until the circuit monitor loses control power. When control power is restored, the relay will not be re-energized if the alarm condition is not TRUE.

Chapter 5Input/Output Capabilities 63230-300-212 Relay Output Operating Modes April 2001
Timed
Remotely Controlled:
Energize the relay by issuing a command from a remote PC or programmable controller. The relay remains energized until the timer expires, or until the circuit monitor loses control power. If a new command to energize the relay is issued before the timer expires, the timer restarts. If the circuit monitor loses control power, the relay will be re-energized when control power is restored and the timer will reset to zero and begin timing again.
Circuit Monitor Controlled:
When an alarm condition assigned to the relay occurs, the relay is energized. The relay remains energized for the duration of the timer. When the timer expires, the relay will de­energize and remain de-energized. If the relay is on and the circuit monitor loses control power, the relay will be re-energized when control power is restored and the timer will reset to zero and begin timing again.
End Of Power Demand Interval
This mode assigns the relay to operate as a synch pulse to another device. The output operates in timed mode using the timer setting and turns on at the end of a power demand interval. It turns off when the timer expires. Because of it’s long life, this mode should be used with solid state relay outputs.
Absolute kW h Pulse
This mode assigns the relay to operate as a pulse initiator with a user-defined number of kWh per pulse. In this mode, both forward and reverse real energy are treated as additive (as in a tie circuit breaker).
Absolute kVARh Pulse
This mode assigns the relay to operate as a pulse initiator with a user-defined number of kVARh per pulse. In this mode, both forward and reverse reactive energy are treated as additive (as in a tie circuit breaker).
kVAhPulse
This mode assigns the relay to operate as a pulse initiator with a user-defined number of kVAh per pulse. Since kVA has no sign, the kVAh pulse has only one mode.
kWhInPulse
This mode assigns the relay to operate as a pulse initiator with a user-defined number ofkWh per pulse. In this mode, only the kWh flowing into the load is considered.
kVARh In Pulse
This mode assigns the relay to operate as a pulse initiator with a user-defined number of kVARh per pulse. In this mode, only the kVARh flowing into the load is considered.
kWh Out Pulse
This mode assigns the relay to operate as a pulse initiator with a user-defined number ofkWh per pulse. In this mode, only the kWh flowing out of the load is considered.
kVARhOut Pulse
This mode assigns the relay to operate as a pulse initiator with a user-defined number of kVARh per pulse. In this mode, only the kVARh flowing out of the load is considered.

Setpoint-controlled Relay Functions

SOLID-STATE KYZ PULSE O UTPUT

The circuit monitor can detect over 100 alarm conditions, including over/ under conditions, digital input changes, phase unbalance conditions, and more (see Chapter 6Alarms on page 83 for more about alarms). Using
SMS, you can configure a relay to operate when an alarm condition is true.
For example, you could set up the three relays on the
IOC44 card to operate
at each occurrence of Undervoltage Phase A.Then, each time the alarm condition occursthat is, each time the setpoints and time delays assigned to Undervoltage Phase A are satisfiedthe circuit monitor automatically operates relays R1, R2, and R3 according to their configured mode of operation. See Relay Output Operating Modeson page 75 of this chapter for a description of the operating modes.
Also, you can assign multiple alarm conditions to a relay. For example, relay AR1 on the IOC-44 card could have Undervoltage Phase Aand Undervoltage Phase Bassigned to it. The relay would operate whenever either condition occurred.
NOTE: Setpoint-controlled relay operation can be used for some types of non-time-critical relaying. For more information, see Setpoint-Controlled Relay Functionson page 88 in
Chapter 6Alarms
.
This section describes the pulse output capabilities of the circuit monitor. For instructions on wiring the
KYZ pulse output, see Wiring the Solid-State KYZ
Outputon page 55 in Chapter 5Wiring of the installation manual.
The circuit monitor is equipped with one solid-state
KYZ pulse output located
near the option card slots. The IOC44 option card also has a solid-state KYZ output. The solid-state relays provides the extremely long lifebillions of operationsrequired for pulse initiator applications.
The
KYZ output is a Form-C contact with a maximum rating of 96 mA.
Because most pulse initiator applications feed solid-state receivers with low burdens, this 96 mA rating is adequate for most applications. For applications where a higher rating is required, the ampere ratings. Use
SMS or the display to configure any of the 10 ampere
IOC44 card provides 3 relays with 10
relays as a pulse initiator output. Keep in mind that the 10 ampere relays are mechanical relays with limited life10 million operations under no load; 100,000 under load.

To set the kilowatthour-per-pulsevalue, use SMS or the display. When setting the kWh/pulse value, set the value based on a 3-wire pulse output. For instructions on calculating the correct value, see Calculating the Kilowatthour-Per-Pulse Valueon page 80 in this chapter.
The circuit monitor can be used in 2-wire or 3-wire pulse initiator applications. Each of these applications is described in the sections that follow.
The
KYZ pulse output can be configured to operate in one of 11 operating
modes. See Relay Output Operating Modeson page 75 for a description of the modes.
The setup in
SMS or at the circuit monitor display is the same as a
mechanical relay. See the previous section Mechanical Relay Outputs” on page 77, for the values you must set up in

2-Wire Pulse Initiator

Most digital inputs in energy management systems use only two of the three wires provided with a KYZ pulse initiator. This is called a 2-wire pulse initiator application. Figure 5–3 shows a pulse train from a 2-wire pulse initiator application.
In a 2-wire application, the pulse train looks like the alternating open and closed states of a Form-A contact. Most 2-wire pulse initiator applications use a Form-C contact, but tie into only one side of the Form-C contact where the pulse is the transition from OFF to ON of that side of the Form-C relay. In Figure 5–3, the transitions are marked as 1 and 2. Each transition represents the time when the relay transitions from KZ to KY. Each time the relay transitions, the receiver counts a pulse. The circuit monitor can deliver up to 25 pulses per second in a 2-wire application.

Some applications require the use of all three wires provided with the KYZ pulse initiator. This is called a 3-wire pulse initiator application. Figure 5–4 shows a pulse train for a 3-wire pulse initiator application.
Three-wire KYZ pulses are the transitions between KY and KZ. These transitions are the alternate contact closures of a Form-C contact. In Figure 5–4, the transitions are marked as 1, 2, 3, and 4. The receiver counts a pulse at each transition. That is, each time the Form-C contact changes state from KY to KZ, or from KZ to KY, the receiver counts a pulse.The circuit monitor can deliver up to 50 pulses per second in a 3-wire application.

Chapter 5Input/Output Capabilities 63230-300-212 Calculating the Watthour-Per-Pulse Value April 2001

CALCULATING THE KILOWATTHOUR-PER-PULSE VALUE

This section shows an example of how to calculate kilowatthours per pulse. To calculate this value, first determine the highest kW value you can expect and the required pulse rate. In this example, the following assumptions are made:
The metered load should not exceed 1600 kW.
About two KYZ pulses per second should occur at full scale.
Step 1: Convert 1600 kW load into kWh/second.
(1600 kW) (1 Hr) = 1600 kWh
(1600 kWh) = “X” kWh
1 hour
1 second
(1600 kWh) = “X” kWh
3600 seconds
1 second
X = 1600/3600 = 0.4444 kWh/second
Step 2: Calculate the kWh required per pulse.
0.4444 kWh/second = 0.2222 kWh/pulse
2 pulses/second
Step 3: Round to nearest hundreth, since the circuit monitor only accepts
0.01 kWh increments.
Ke = 0.22 kWh/pulse
Summary:
3-wire application0.22 kWh/pulse provides approximately 2 pulses per
second at full scale.
2-wire application0.11 kWh/pulse provides approximately 2 pulses per
second at full scale. (To convert to the kWh/pulse required for a 2-wire application, divide Ke by 2. This is necessary because the circuit monitor Form C relay generates two pulsesKY and KZfor every pulse that is counted.)

ABOUT ALARMS

Alarms Groups

The circuit monitor can detect over 100 alarm conditions, including over or under conditions, digital input changes, phase unbalance conditions, and more. It also maintains a counter for each alarm to keep track of the total number of occurrences. A complete list of default alarm configurations are described in Table 6–3 on page 94. In addition, you can set up your own custom alarms and set up relays to operate on alarm conditions.
When one or more alarm conditions are true, the circuit monitor will execute a task automatically. Using
SMS or the display, you can set up each alarm
condition to perform these tasks:
Force data log entries in up to 14 user-defined data log files. See Chapter 7Logging on page 99 for more about data logging.
Perform event captures. See Chapter8Waveform and Event Capture
on page 107 for more about event recording.
Operate relays. Using
SMS you can assign one or more relays to operate
when an alarm condition is true. See the SMS online help for more about this topic.
Whether you are using a default alarm or creating a custom alarm, you first choose the alarm group that is appropriate for the application. Each alarm condition is assigned to one of these alarm groups:
StandardStandard alarms have a detection rate of 1 second and are useful for detecting conditions such as over current and under voltage. Up to 80 alarms can be set up in this alarm group
High SpeedHigh speed alarms have a detection rate of 100 milliseconds and are useful for detecting voltage sags and swells lasting only a few cycles. Up to 20 alarms can be set up in this group.
DisturbanceDisturbance alarms have a detection rate one cycle and are useful for detecting voltage sags and swells. Up to 20 alarms can be set up in this group. See Chapter 9Disturbance Monitoring on page 113 for more about disturbance monitoring.
DigitalDigital alarms are triggered by an exception such as the transition of a digital input or the end of an incremental energy interval. Up to 40 alarms can be set up in this group.
BooleanBoolean alarms use Boolean logic to combine up to four enabled alarms. You can choose from the Boolean logic operands:
NAND, OR, NOR
,orXOR to combine your alarms. Up to 15 alarms can be
AND,
set up in this group.

Use either
SMS or the display to set up any of the alarms.

63230-300-212 Chapter 6Alarms April 2 001 About Alarms

Setpoint-Driven Alarms

Many of the alarm conditions require that you define setpoints. This includes all alarms for over, under, and phase unbalance alarm conditions. Other alarm conditions such as digital input transitions and phase reversals do not require setpoints. For those alarm conditions that require setpoints, you must define the following information:
Pickup Setpoint
Pickup Delay (depending on the alarm group, you choose the time in
seconds, 100 ms increments, or cycles)
Dropout Setpoint
Dropout Delay (depending on the alarm group, you choose the time in
seconds, 100 ms increments, or cycles)
NOTE: Alarms with both Pickup and Dropout setpoints set to zero are invalid.
To understand how the circuit monitor handles setpoint-driven alarms, see Figure 6–2 on page 86. Figure 6–1 shows what the actual alarm Log entries for Figure 6–2 might look like, as displayed by
SMS.
NOTE: The software does not actually display the codes in parentheses EV1, EV2, Max1, Max2. These are references to the codes in Figure 6–2.

Priorities

Alarm Levels

Each alarm also has a priority level. Use the priorities to distinguish between events that require immediate action and those that do not require action.
High priorityif a high priority alarm occurs, the display informs you in
two ways: the LED onthe display flashes until you acknowledge the alarm and a message displays while the alarm is active.
Medium pr iorityif a medium priority alarm occurs, the LED flashes and
a message displays only while the alarm is active. Once the alarm becomes inactive, the LED stops flashing.
Low priorityif a low priority alarm occurs, the LED on the display
flashes only while the alarm is active. No alarm message is displayed.
No priority—if an alarm is setup with no priority, no visible representation
will appear on the display. Alarms with no priority are not entered in the Alarm Log. See Chapter 7Logging for alarm logging information.
If multiple alarms with different priorities are active at the same time, the display shows the alarm message for the last alarm that occurred. For instructions on setting up alarms from the circuit monitor display, see Setting Up and Editing Alarmson page 21.
From the display or
SMS, multiple alarms can be set up for one particular
quantity (parameter) to create alarm levels. You can take different actions depending on the severity of the alarm.
For example, you could set up two alarms for kW Demand. A default alarm already exists for kW Demand (no. 26 in the alarm list), but you could create another custom alarm for kW Demand, selecting different pickup points for it. The custom kW Demand alarm, once created, will appear in the standard alarm list. For illustration purposes, let’s set the default kW Demand alarm to 120 kW and the new custom alarm to 150 kW. One alarm named
Demand
; the other
kW Demand 150kW
as shown in Figure 6–3. Note that if
kW
you choose to set up two alarms for the same quantity, use slightly different names to distinguish which alarm is active. The display can hold up to 15 characters for each name. You can create up to 10 alarm levels for each quantity.

Chapter 6Alarms 63230-300-212 Custom Alarms April 2001

CUSTOM ALARMS

SETPOINT-CONTROLLED RELAY FUNCTIONS

The circuit monitor has many pre-defined alarms, but you can also set up your own custom alarms. For example, you may need to alarm on the ON-to­OFF transition of a digital input. To create this type of custom alarm:
1. Select the appropriate alarm group (digital in this case).
2. Select the type of alarm (described in Table 6–4 on page 96).
3. Give the alarm a name.
After creating a custom alarm, you can configure it by applying priorities, setting pickups and dropouts (if applicable), and so forth. For instructions on creating custom alarms, see Creating a New Custom Alarmon page 19 in Chapter 3Operation.
NOTE: The circuit monitor will automatically create alarms for the IOC44 and the IOX when the modules are identified. These are OFF-to-ON alarms.
A circuit monitor can mimic the functions of certain motor management devices to detect and respond to conditions such as phase loss, undervoltage, or reverse phase relays. While the circuit monitor is not a primary protective device, it can detect abnormal conditions and respond by operating one or more Form-C output contacts. These outputs can be used to operate an alarm horn or bell to annunciate the alarm condition.
NOTE: The circuit monitor is not designed for use as a primary protective relay. While its setpoint-controlled functions may be acceptable for certain applications, it should not be considered a substitute for proper circuit protection.
If you determine that the circuit monitor’s performance is acceptable for the application, the output contacts can be used to mimic some functions of a motor management device. When deciding if the circuit monitor is acceptable for these applications, keep the following points in mind:
Circuit monitors require control power to operate properly.
Circuit monitors may take up to 5 seconds after control power is applied
before setpoint-controlled functions are activated. If this is too long, a reliable source of control power is required.
When control power is interrupted for more than approximately 100 milliseconds, the circuit monitor releases all energized output contacts.
Standard setpoint-controlled functions may take 1–2 seconds to operate, in addition to the intended delay.
A password is required to program the circuit monitor’s setpoint controlled relay functions.
Changing certain setup parameters after installation may operate relays in a manner inconsistent with the requirements of the application.
For instructions on configuring setpoint-controlled alarms or relays from the circuit monitors display, see Setting Up and Editing Alarmson page 21. The types of available alarms are described later in this chapter in Ta b le 6 –3 on page 94.
