Considerations When Installing Meters

- Installation must be performed by only qualified personnel who follow standard safety precautions during all procedures. Personnel should have appropriate training and experience with high voltage devices. Appropriate safety gloves, safety glasses and protective clothing are recommended.

- During normal operation of the meter, dangerous voltages flow through many parts of the meter, including: Terminals and any connected CTs (Current Transformers) and PTs (Potential Transformers), all I/O modules (Inputs and Outputs) and their circuits. All primary and secondary circuits can, at times, produce lethal voltages and currents. Avoid contact with any currentcarrying surfaces.

- Do not use the meter or any I/O output device for primary protection or in an energy-limiting capacity. The meter can only be used as secondary protection. Do not use the meter for applications where failure of the meter may cause harm or death. Do not use the meter for any application where there may be a risk of fire.

- All meter terminals should be inaccessible after installation.

- Do not apply more than the maximum voltage the meter or any attached device can withstand. Refer to meter and/or device labels and to the Specifications for all devices before applying voltages. Do not HIPOT/Dielectric test any Outputs, Inputs or Communications terminals.

- AMETEK recommends the use of shorting blocks and fuses for voltage leads and power supply to prevent hazardous voltage conditions or damage to CTs, if the meter needs to be removed from service. CT grounding is optional.

- AMETEK recommends using a dry cloth to wipe the meter.

NOTE

M a k e s u r e t h e voltage of power supply is the same as what the meter n e e d e d f o r i t s auxiliary power.

Fig 2-7 Earth Ground Symbol

Auxiliary Power

The auxiliary power supply of the DPMS XL+ meter is 100-415Vac (50/60Hz) or 100-300Vdc. The meter’s typical power consumption is very little so it can be supplied by an independent source or by the line to be measured. A regulator or a

UPS should be used when the power supply varies too much. The terminals for the auxiliary power supply are 11, 12 and 13 (L, N, and Ground). A switch or circuit-breaker shall be included in the building installation, and it shall be in close proximity to the equipment and within easy reach of the operator, and it shall be marked as the disconnecting device for the equipment.

Voltage Input

Input voltage of DPMS XL+ should be 400 LN/690 LL VAC rms(three phases)

-

400 LN VAC(single phase).

In a high voltage system, a PT must be used. The secondary output of the

PT should be 100V or 120V typically. The accuracy of the measurement is related to the PT you select, so be careful! For the star system, the

POWER INSTRUMENTS primary rated voltage of the PT is equal to or close to the phase voltage of the system. For the delta system, it is the line voltage of the system.

A fuse (typical 1A/250Vac) should be used in a voltage input loop. The wire size of the voltage input could be AWG16-12 or 1.3-2.0mm

2

.

Note:

In no circumstance could the secondary of PT be shorted. The secondary of the PT should be well grounded at one end.

Current Input

In a practical engineering application, CTs should be installed in the measured loop. Normally the CT secondary is 5A. 1A is possible as an ordering option. A CT accuracy of over 0.5% (rating over 3VA) is recommended and it will influence the measuring accuracy. The wire between the CT and DPMS XL+ should be as short as possible. The length of the wire may increase the error of the measurement. CTs must be required if the rated current is over 5A.

The wire size of the current input could be AWG15-10 or 1.5-2.5mm

2

.

The CT loop should not be open in any circumstance when the power is on. There should not be any fuse or switch in the CT loop and one end of the CT loop should be well connected to ground.

Vn Connection

Vn is the reference point of the DPMS XL+ voltage input. The lower the wire resistance, the better the accuracy. The wiring mode of Vn depends greatly on the system wiring mode. Please refer to the wiring diagram.

Three phase wiring diagram

The DPMS XL+ can satisfy almost all kinds of three phase wiring diagrams.

Please read this part carefully before you begin to do the wiring so that

15

DPMS XL+ Series Multi-function Power Meter you can choose a suitable wiring method for your power system.

The voltage and current input wiring mode can be set separately during the meter parameter setting process. The voltage wiring mode could be

3-phase 4-line Wye (3LN), 3-phase 4-line 2PT Wye mode (2LN) and 3-phase

3-line open delta (2LL). The current input wiring mode could be 3CT,

2CT and 1CT. Any voltage mode could be grouped with one of the current mode.

Voltage Input Wiring

3-Phase 4-Line Wye mode (3LN)

The 3-Phase 4-Line Wye mode is commonly used in low voltage electric distribution power systems. The power line can be connected to the meter voltage input directly as in fig 2.10a. In the high voltage input system, 3PT Wye mode is often used as in fig 2.10b. The voltage input mode of the DPMS XL+ should be set to 3LN for both voltage input wiring modes.

Communication

The communication port and protocol of the DPMS XL+ are RS485 and

Modbus-RTU. The comm terminals are A, B, and S (14, 15, 16). A is a differential signal +, B is differential signal - and S is connected to the twisted pair shield. Please use good quality shielded twisted pair cable, AWG22 (0.5mm

2

) or higher. The overall length of the RS485 cable connecting all devices should not exceed 1200m (4000ft). The DPMS XL+ is used as a slave device of masters like PC, PLC, data collector or RTU.

If the master does not have an RS485 communication port, a converter has to be used. Normally an RS232/RS485 or USB/RS485 is adopted. The topology of RS485 net can be line, circle and star.

For high quality communication, good quality shielded twisted pair of cable AWG22 (0.5mm

2

) or higher is highly recommended.

25

DPMS XL+ Series Multi-function Power Meter

The shield of each segment of the RS485 cable must be connected to the ground at one end only.

Every A(+) should be connected to A(+), B(-) to B(-), or it will influence the network, or even damage the communication interface.

The connection topology should avoid “T” type which means there is a new branch and it does not begin from the beginning point.

Keep communication cables away as much as possible from sources of electrical noise.

When many devices are connected to the same long communication line, an anti-reflection resistor of 120Ω-300Ω is preferred which will be connected to A and B at the end of the line.

Use an RS232/RS485 or USB/RS485 converter with optical isolated output and surge protection.

3.8 Page recovery Function

The DPMS XL+ has the page recovery function, which means that the meter stores the current display page in the non-volatile memory during power off and reloads the page when power recovers. If power goes off when displaying the parameter setting mode, the meter will start with the page of voltage display when power recovers. If power goes off when displaying at the expanded I/O module data mode, and this expanded I/O module is not connected when power recovers, the meter will start with the page of voltage display.

DPMS XL+ Series Multi-function Power Meter

The function of the DPMS XL+ is very powerful. It can measure almost all the parameters in the power system. Some of its functions may not be controlled by simply pressing the keys. We’ll introduce functions with the help of the software interface in this chapter. The version of the software you get may be advanced or it may differ somewhere, please refer to the manual that goes with it.

4.1 Basic Analog Measurements

The DPMS XL+ can measure voltage, current, power, frequency, power factor and demand etc with high accuracy, shown as below:

Fig 4.1 Real-Time Metering

58

POWER INSTRUMENTS

Demand:

Types of demand calculated in the DPMS XL+ are: active power demand of three phase, reactive power demand of three phases, and apparent power demand of three phases. Demand memory can be cleared. To clear is to reset all the registers to 0, like the initialization of the meter

(demand calculation only).

Demand calculating mode can be set as sliding window and thermal according to user. The figure 4-7 shows how it works.

In the sliding window interval, you select an interval from 1 to 30 minutes, which is the period of the calculation. The demand updates every minute.

Thermal demand method calculates the demand based on a thermal response which mimics the thermal demand meter. You select the period for the calculation and the demand updates at the end of each period.

Energy:

Various kinds of energy will be accumulated in the DPMS XL+. Real time energy: the accumulation of energy for the kWh, kvarh and kVAh since cleared last time.

Calculating mode

1. You can select the calculating mode from fundamental based or fullwave based by pressing a key or via communication port. Fundamental based calculating is to accumulate energy ignoring harmonics while fullwave based calculating is to accumulate energy including fundamental and harmonics.

Note:

When fundamental based calculating is selected, PF is that of a

59

Figure 4-2 energy and power quality parameters

Current direction adjustment

The normal current direction is from port 1 to port 2, but sometimes

POWER INSTRUMENTS incorrect wiring may result. To adjust the direction of current, the three current directions can be set as “Negative” which means reversing 180 degrees and “Positive” which means normal. It is easy to get the right data without changing the wiring. It is also shown in figure 4-7.

4.2 Max/Min

Figure 4-3 Max/Min

The DPMS XL+ can produce statistics of the maximum and minimum values of phase/line voltages, currents, power, reactive power, apparent power, power factor, frequency, demand, unbalance factor, THD as well as the time they occur. All the data will be stored in non-volatile memory

61

DPMS XL+ Series Multi-function Power Meter so that it will not be lost when the power supply is off. All of the maximum and minimum data can be accessed via communication port or panel, but the time stamps can only be accessed via communication port.

The statics can be cleared via communication port or panel buttons.

4.3 Harmonics and Power Quality Analysis

1. Harmonics

The DPMS XL+ can measure and analyze THD, Harmonics (2nd to 31st), even HD, odd HD, Crest Factor, THFF, K factor etc. They are shown in figure 4-2.

2. Phase angle:

Phase angle indicates the angle between U1 and other voltage and current parameters. It ranges from 0 to 360 degrees. This function is to help you find out the relationship between all input signals avoiding incorrect wiring. When it is set to “2LL” or “3LL”, it gives out the phase angles of u23, i1, i2, i3 corresponding to u12. For other settings, it gives out the phase angles of u2, u3, i1, i2, i3 corresponding to u1. They are shown in figure 4-4.

3. Sequence component and unbalance analysis

The DPMS XL+ will do some sequential analysis for the input signal. It provides the positive sequence, negative sequence and zero sequence of the fundamentals and does the unbalance analysis of voltage and current.

Sequence components are shown in figure 4-4, unbalance of voltage and current are shown in figure 4-1.

62

POWER INSTRUMENTS

Figure 4-4 Sequence component and Phase angle

4.4 Over-Range Alarming

In the DPMS XL+, when the metering data is over the pre-set limit and over pre-set time interval, the over limit alarm will be picked up. The over limit value and time stamp will be recorded and the maximum number of records is 16. The digital output (DO) and RO can be used

(if extended I/O modules are connected) as a trigger to light or sound alarm.

In order to use the over-range alarm function, you should finish all the settings (equation or inequation or enable switches) correctly, or it will

63

DPMS XL+ Series Multi-function Power Meter fail. All of the settings can be accessed by writing to their corresponding

64 registers via communication port as shown in figure 4-5.

Parameter code: used to select a parameter for this group. For example:

0-frequency, 44-AI4 sampling data. Then this parameter will be monitored.

Comparison mode: set alarm condition 1: larger, 2: equal, 3: smaller. For example: if you choose frequency, larger, and setting value is 50, then it will alarm when the frequency is larger than 50Hz.

Notice:

the relationship between communication setting value and actual value is the same as that of the selected parameter.

Delay time: if the alarm condition lasts for a specified time period, an alarm will be valid and recorded. It ranges from 0 to 3000 (unit: 10ms).

When it is set to 0, there is no delay after the condition is setup. If it is set to 20, it will delay 20*10=200ms.

Output to relay: 0-the alarm will not output to RO, if it is set as 1 and

IO1 is connected, it will output to RO1 when alarm happens and RO1 will be turned off until all alarms output to RO1 are reset. RO2~RO8 are the same as RO1.

Notice:

if RO is under alarm mode, it can only work in “latch” mode.

After the single alarm group setting is finished, you need to go on and finish the following global setting or the alarm won’t work.

2. Global settings

The addresses of all the global variables are 1046H~104dH in system parameters.

65

DPMS XL+ Series Multi-function Power Meter

“Global alarming enable” determines whether the alarm function of this meter works or not. Only when it is set as “1”, the alarm function is enabled.

When “Alarming flash enable“ is set to be “1”, the backlight will flash when the alarm happens.

“Alarming channel enable setting” determines whether the corresponding group is enabled or not. There are 16 groups in all and each one is corresponding to one bit of a 16-bit register. For each group, whether it works or not depends on the enable setting. If some bits of the register are “1”, it means their corresponding groups take effect.

“Logical “And” between alarming setting”: The 16 alarm records in the

DPMS XL+ are divided into 8 pairs. Each pair has two groups. The two groups can be logically “and” by controlling the logic switch. When two groups are “and”, the alarm happens only if both the conditions are met.

If the switch is off, the two groups work independently.

The 8 pairs are arranged as follows: according to their serial number, the

1st & 2nd = pair 1; the 3rd & 4th = pair 2; the 5th & 6th = pair 3; 7th &

8th = pair 4; 9th & 10th = pair 5; 11th & 12th = pair 6; 13th & 14th = pair 7;

15th & 16th = pair 8.

This function is controlled by the lower 8 bits of a 16 bit register, each bit is corresponding to a pair. “1” means this function is enabled and “0” means disabled.

“Alarming output to DO1 setting”: When “Digital output mode” is set to “1”, DO1 can be used as alarming output. A 16-bit register is used to finish this function, its bit0~bit15 are corresponding to the 1st ~16th group respectively. When the related I/O module is connected and under

66

POWER INSTRUMENTS alarm mode, if corresponding bit is set to 1 and the alarm condition is met, then it will output to DO1 and DO1 will be turned off until all alarms output to DO1 are reset. If related bit is set to 0, it doesn’t affect DO1.

DO2~DO4 are the same as DO1.

After finishing the previous steps correctly, the alarm function is available.

3. Setting Example

We’ll show you an example of how to use the logical “and” in a pair.

We set an event as follows: I1 greater than 180A, delay 5s for the 1st group; U1 less than 9980V, delay 10s for the 2nd group. No output is available. The CT primary value of I1 is 200A, and CT2 is 5A. The primary voltage of U1 is 10000V, PT2 is 100V. Then let’s see how all the related registers are to be set.

Settings of first group:

“Parameter code (104eH)” is set to 9, which stands for I1.

“Comparison mode (104fH)” is set to 1, which stands for larger.

“Setting value (1050H)” is set to 4500, according to the relationship between actual value and communication value (I=Rx *

-

CT1/CT2

-

/1000).

“Delay time (1051H)” is set to 500, so the actual delay time is

500*10ms=5s.

“Output to relay (1052H)” is set to 0, because there is no output to RO.

Settings of second group:

“Parameter code (1053H)” is set to 1, which stands for U1.

“Comparison mode (1054H)” is set to 3, which stands for smaller.

“Setting value (1055H)” is set to 998, according to the relationship between actual value and communication value (U=Rx X

-

PT1/PT2

-

/10).

67

DPMS XL+ Series Multi-function Power Meter

“Delay time (1056H)” is set to 1000, so the actual delay time is

1000*10ms=10s.

“Output to relay (1057H)” is set to 0, because there is no output to RO.

Global settings:

“Alarming channel enable setting (1048H)” is set as 0x0003, which enables the first and the second channel.

“Logical "AND" between alarming setting (1049H)” is set as 0x0001, which enable logic "AND" in Pair 1.

“Alarming output to DO1 setting (104aH)” is set to 0, because there is no output to DO1.

“Alarming output to DO2 setting (104bH)” is also set to 0.

“Alarming output to DO3 setting (104cH)” is also set to 0.

“Alarming output to DO4 setting (104dH)” is also set to 0.

“Alarming flash enable (1047H)” is set to 0, which does not enable backlight flashing when alarm occurred.

“Global alarming enable (1046H)” is set to 1, which enables the Over-

Range alarming.

4. Records of Alarm Event

There are 16 groups of alarm event records to be stored. But they are not corresponding to setting records, they are recorded in cycle. The latest event will cover the oldest one. It begins at the 1st record when the power is turned on. When over range parameters return to normal, the time stamp and value will be recorded as well. So you can work out the duration of over range by checking the changing time.

68

Related with parameters

“Alarming status” indicates information of the current alarm status. It is a 16-bit unsigned integer. Parameter code is stored in the higher 8 bits.

Bit1 indicates whether logic "AND" is enabled or not, 1 means enabled and 0 means not. Bit0 indicates whether an alarm occurred or recovered,

1 means occurred and 0 means recovered. Undefined bits are 0.

“Parameter code” indicates which parameter is recorded.

“Value” indicates the recorded value when alarm happens and recovers.

“Time” indicates the time stamp with the accuracy of ms.

Alarm event will set bit0 of “system status (102eH)” to 1. At the same time, corresponding flags will be set to 1 to indicate new data. It should be cleared after the controller has read the data, and then bit0 of “system status (102eH)” will be set to 0.

Note:

alarm records will not be lost during power off. The pointer will point to the 1st group of records after it is powered on again.

DPMS XL+ Series Multi-function Power Meter

This chapter will mainly discuss how to handle the meter via the communication port using software. To master this chapter, you should be familiar with Modbus and have read other chapters of this manual, and you have generously mastered the function and application of this product.

This chapter includes: Modbus protocol, format of communication and data address table and the DPMS XL+ application details.

5.1 Introducing Modbus Protocol

The Modbus RTU protocol is used for communication in the DPMS XL+.

The data format and error check methods are defined in the Modbus protocol. The half duplex query and respond mode is adopted in Modbus protocol. There is only one master device in the communication net.

The others are slave devices, waiting for the query of the master.

Transmission mode

The mode of transmission defines the data structure within a frame and the rules used to transmit data. The mode is defined in the following which is compatible with Modbus RTU Mode*.

Address Field

The address field of a message frame contains eight bits. Valid slave device addresses are in the range of 0~247 decimal. A master addresses a slave by placing the slave address in the address field of the message.

When the slave sends its response, it places its own address in this address field of the response to let the master know which slave is responding.

Function Field

The function code field of a message frame contains eight bits. Valid codes are in the range of 1~255 decimal. When a message is sent from a master to a slave device the function code field tells the slave what kind of action to perform.

Table5.2 Function Code

Data Field

The data field is constructed using sets of two hexadecimal digits, in the range of 00 to FF hexadecimal. The data field of messages sent from a master to slave devices contains additional information which the slave must use to take the action defined by the function code. This can include items like discrete and register addresses, the quantity of

75

DPMS XL+ Series Multi-function Power Meter items to be handled, and the count of actual data bytes in the field.

For example, if the master requests a slave to read a group of holding registers (function code 03), the data field specifies the starting register and how many registers are to be read. If the master writes to a group of registers in the slave (function code 10 hexadecimal), the data field specifies the starting register, how many registers to write, the count of data bytes to follow in the data field, and the data to be written into the registers.

If no error occurs, the data field of a response from a slave to a master contains the data requested. If an error occurs, the field contains an exception code that the master application can use to determine the next action to be taken. The data field can be nonexistent (of zero length) in certain kinds of messages.

Error Check Field

Messages include an error’s checking field that is based on a Cyclical

Redundancy Check (CRC) method. The CRC field checks the contents of the entire message. It is applied regardless of any parity check method used for the individual characters of the message. The CRC field is two bytes, containing a 16 bit binary value. The CRC value is calculated by the transmitting device, which appends the CRC to the message.

The receiving device recalculates a CRC during receipt of the message, and compares the calculated value to the actual value it received in the

CRC field. If the two values are not equal, an error will result. The CRC is started by first preloading a 16-bit register to all 1’s. Then a process begins of applying successive 8-bit bytes of the message to the current contents of the register. Only the eight bits of data in each character are used for generating the CRC. Start and stop bits, and the parity bit, do

76

POWER INSTRUMENTS not apply to the CRC. During generation of the CRC, each 8-bit character is exclusive ORed with the register contents. Then the result is shifted in the direction of the least significant bit (LSB), with a zero filled into the most significant bit (MSB) position. The LSB is extracted and examined.

If the LSB was a1, the register is then exclusive ORed with a preset, fixed value. If the LSB was a 0, no exclusive OR takes place. This process is repeated until eight shifts have been performed. After the last (eighth) shift, the next 8-bit byte is exclusive ORed with the register current value, and the process repeats for eight more shifts as described above.

The final contents of the register, after all the bytes of the message have been applied, is the CRC value. When the CRC is appended to the message, the low-order byte is appended first, followed by the high-order byte.

1. Data type:

“bit” refers to binary.

“word” refers to 16-bit unsigned integer using one data address and 2 bytes of memory, it varies from 0 to 65535.

“int” refers to 16-bit integer using one data address and 2 bytes of memory, it varies from -32768 to32767.

“dword” refers to 32-bit unsigned integer using two data addresses and 4 bytes of memory with high word at the front and low word at the end, it varies from 0 to 4294967295. Rx=high word *65536+low word.

“float” refers to 32-bit single value using two data addresses and 4 bytes of memory, it varies from -1.175494E-38 to 3.402823E+38.

2. Relationship between communication value and numerical value.

Important Note: Regions from “System parameters settings” to “AO transforming parameter settings” are the regions that can be set and

83

DPMS XL+ Series Multi-function Power Meter modified. Please follow the rules when you communicate with the DPMS

XL+.

1. Using function code 10H, one communication order can only modify contents in one region, such as “System parameters settings”, ”System status parameter”, “Date and Time table”, “Over-range alarming-Global settings”, “Over-range alarming-Single settings”, “I/O Modules settings”.

It can not be accomplished in one communication order to modify contents in both of two or more regions above.

2. Using function code 03H, there is no such rules described above.

System parameter setting

System parameters determine how the meter works. You should understand them clearly by referring to chapter 3 and chapter 4.

Basic Analog measurements

There are two different modes to read basic analog measurements, one is secondary mode, and another is primary mode. In primary mode, the numerical value in the DPMS XL+ register is equal to the real physical value. In secondary mode, the relationship between numerical values in the register and the real physical value is as follows. (Rx is the numerical value in the DPMS XL+ register)
