2.2 Naming Rules

Chapter 3 Installation

3.1 Inspection

The instrument is no longer safe when, a) Shows clear signs of damage b) Does not work c) Long storage under extreme conditions d) Damage during shipment

3.2 Safety

Please use the soft dry clothes to clean the instrument. Please do not use any chemical or detergent or volatile solvents to clean the instrument, in order to avoid any possibility of the cover damage.

3.2.1 Dimension and Latch

 Products come with external split type clip-on CT’s. Disconnect the CT’s or use

other CT’s is highly prohibited.

 Please read this operation manual carefully before using.  Please re-confirm the measure position.  PM-4324 series can be installed as rail mounting mode or embedded, no need to

drill a hole or screw to fix it (rail mounting width can up to the length of 35 mm).

 Meter auxiliary power is +100 ~ +240 VAC.

3.2.2 Mounting and Dismounting

 Mounting

Assembly: Place the PM-4324 on the DIN-Rail. Push the front of the PM-4324 toward the mounting surface until it audibly snaps into place. Dismantling: Pull out the latch and then remove the PM-4324 from the DIN-Rail.

 Wire Disconnection

1. Open the CT clip to detach the CT, do not remove the CT terminal lines if possible Note: if you need to remove the terminal lines, always detach the CT before removing the CT terminal lines. Otherwise the CT may develop open-circuit

secondary voltages which may be hazardous to personnel or damaging to the CT or equipment connected in the secondary circuit.

2. Disconnect the voltage input wires from terminals and wrap the wire tips with plastic tape.

3. Disconnect the communication wires from terminal.

4. Disconnect the auxiliary power from terminal and wrap the wire tip with plastic tape.

 At the bottom of the CT, there is a

“K→L” mark.

 Open the CT clip.

 Make sure the power current

direction follow the “K→L” mark on the CT and then close the CT clip.

 Installation steps finished.

3.2.3 CT’s installation steps

Chapter 4 Wiring Diagrams

4.1 Connection

Please firstly check the current input terminal, and then in white black, white black, white black wire sequences (CT1-K, CT1-L, CT2-K, CT2-L, CT3-K, CT3-L). Then

connect the CT’s, and close the CT clip. Make sure the arrow direction sign on CT’s

follows current flow direction（K→L）

Note: it must be in the same direction. Connect the voltage input terminal N C B A. for PM-4324, in the three phase order as follows on N C B A.

Attention please!! For 3P3W-2CT, connect in N C A phase sequence, do not connect phase B (Check the diagram).

Voltage Input

1. PM-4324 series: Input Voltage up to 500V. For any higher Input Voltage large than 500V, please add the PT (power transformer), and Change PT RATIO setup.

2. Confirm the RST (ABC) phase sequence.

Current Input

1. The external CT’s are fragile, please handle with care.

2. The current input of PM-4324 series is in mA range. Only the ex-factory attached CT’s can be used. The other CT’s, for example, from panel will damage the instrument due to its large current (around 5A)

3. When more than one smart meter (PM-4324 series) are installed, please do not disconnect the CT with its original meter and mix use with each other. Since each set of smart meter (PM-4324 series) and its attached split type clip-on CT are calibrated set by set. The mix use may cause wrong measurements.

4. To install CT’s correctly, please ensure the CT lines sequences is right before clip the CT’s onto the power cable of the monitoring equipment. (Detail will be found in next section)

5. When measuring the current, the secondary circuit of a CT should never be opened when a load is passing through its primary. Make sure you always open

the CT clip to detach the CT before removing the terminal lines. Otherwise, it will cause severe injury.

6. Please handle with extra care, especially when the operation space of CT’s is limited.

7. The current direction must follow K-L marked on CT’s.

8. Please select the right size CT’s for different size of monitoring equipment cables: power cable diameter ＜Φ10 use 60A CT，Φ10～Φ16 use 100A CT，Φ16～Φ24 use 200A CT, ，Φ36 use 300A CT，Φ36 use 400A CT

9. The maximum current value cannot exceed the CT rating

7.2 CANopen Protocol

The CANopen is a kind of network protocols evolving from the CAN bus, used on car control system in early days, and has been greatly used in various applications, such as vehicles, industrial machines, building automation, medical devices, maritime applications, restaurant appliances, laboratory equipment & research.

7.2.1 SDO Introduction

7.2.1.1 Upload SDO Protocol

Initiate SDO Upload Protocol

Before transferring the SDO segments, the client and server need to communicate with each other by using the initiate SDO upload protocol. Via the initiate SDO upload protocol, the SDO client will inform the SDO server what object the SDO client wants to request. As well, the initiate SDO upload protocol is permitted to transmit up to four bytes of data. Therefore, if the data length of the object, which the SDO client can read, is equal to or less than the permitted data amount, the SDO communication will be finished only by using the initial SDO upload protocol, i.e. if the data upload is less enough to be transmitted in the initiate SDO upload protocol, then the upload SDO segment protocol will not be used. The communication process of this protocol is shown as follows.

ccs: client command specified

2: initiate upload request scs: server command specified

2: initiate upload response n : Only valid if e = 1 and s = 1, otherwise 0.

If valid, it indicates the number of bytes in d that do not contain data. Bytes [8-n, 7]

do not contain segment data. e: transfer type

0: normal transfer

1: expedited transfer

If the e=1, it means that the data of the object are equal or less than 4 bytes, and

only initiate SDO upload protocol is needed. If e=0, the upload SDO segment

protocol is necessary. s: size indicator

0: Data set size is not indicated.

1: Data set size is indicated. m: multiplexer

It represents the index/sub-index of the data to be transfer by the SDO. The first

two bytes are the index value and the last byte is the sub-index value.

d: data

e=0, s=0: d is reserved for further use.

e=0, s=1: d contains the number of bytes to be uploaded, and byte 4 contains the

least significant bit, and byte 7 contains the most significant bit.

e=1, s=1: d contains the data of length 4-n to be uploaded, the encoding depends

on the type of the data referenced by index and sub-index.

e=1, s=0: d contains unspecified number of bytes to be uploaded. x: not used, always 0 reserved: reserved for further use , always 0

Upload SDO Segment Protocol

When the upload data length is over 4 bytes, the upload SDO segment protocol will be needed. After finishing the transmission of the initiate SDO upload protocol, the SDO client will start to upload the data. The upload SDO segment protocol will comply with the process shown below.

ccs: client command specified

3: upload segment request scs: server command specified

0: upload segment response t: toggle bit.

This bit must alternate for each subsequence segment that is uploaded. The first

segment will have the toggle bit set to 0. The toggle bit will be equal for the

request and response message. c : indicates whether where are still more segments to be uploaded

0: more segments to be uploaded.

1: no more segment to be uploaded. seg-data: It is at most 7 bytes of segment data to be uploaded.

The encoding depends on the type of the data referenced by index and sub-index. n: It indicates the number of bytes in seg-data that do not contain segment data.

Bytes [8-n, 7] do not contain segment data. n = 0 if no segment size is indicated.

x: not used, always 0 reserved: reserved for further use , always 0

7.2.1.2 Download SDO Protocol

Initiate SDO Download Protocol

The download modes are similar to the upload modes, but different in some parameters of the SDO messages. They are also separated into two steps. If the download data length is less than 4 bytes, the download action will finish in the download initialization protocol. Otherwise, the download segment protocol will be needed. These two protocols are shown below.

ccs: client command specified

1: initiate download request scs: server command specified

3: initiate download response n: Only valid if e = 1 and s = 1, otherwise 0.

If valid, it indicates the number of bytes in d that do not contain data. Bytes [8-n, 7]

do not contain segment data. e: transfer type

0: normal transfer

1: expedited transfer

If the e=1, it means that the data of the object are equal or less than 4 bytes, and

only initiate SDO download protocol is needed. If e=0, the download SDO segment

protocol is necessary. s: size indicator

0: Data set size is not indicated.

1: Data set size is indicated. m: multiplexer

It represents the index/sub-index of the data to be transfer by the SDO. The first

two bytes are the index value and the last byte is the sub-index value. d: data

e=0, s=0: d is reserved for further use.

e=0, s=1: d contains the number of bytes to be downloaded, and byte 4 contains

the least significant bit, and byte 7 contains the most significant bit.

e=1, s=1: d contains the data of length 4-n to be downloaded, the encoding

depends on the type of the data referenced by index and sub-index.

e=1, s=0: d contains unspecified number of bytes to be downloaded.

x: not used, always 0 reserved: reserved for further use , always 0

Download Segment Protocol

ccs: client command specified

0: download segment request scs: server command specified

1: download segment response seg-data: It is at most 7 bytes of segment data to be downloaded.

The encoding depends on the type of the data referenced by index and sub-index. n: It indicates the number of bytes in seg-data that do not contain segment data.

Bytes [8-n, 7] do not contain segment data. n = 0 if no segment size is indicated. c: It indicates whether there are still more segments to be downloaded.

0:more segments to be downloaded.

1:no more segments to be downloaded. t: toggle bit

This bit must alternate for each subsequent segment that is downloaded. The first

segment will have the toggle-bit set to 0.The toggle bit will be equal for the request

and the response message.

x: not used, always 0 reserved: reserved for further use , always 0

7.2.1.3 Abort SDO Transfer Protocol

In some conditions, the SDO client or SDO server will terminate the SDO transmission. For example, the value of entries that users want to modify does not exist or is read-only, even users wouldn’t continue the uncompleted SDO protocol under some special situations. When these conditions occur, both the client and the server can be activated to send the Abort SDO Transfer message. The Abort SDO Transfer protocol is shown below.

cs: command specified

4: abort transfer request

x: not used, always 0 m: multiplexer

It represents index and sub-index of the SDO d: contains a 4-byte “Abort Code” about the reason for the abort.

7.2.2 PDO Introduction

7.2.2.1 PDO COB-ID Parameters

Before the real-time data are transmitted by the PDO, it is necessary to check the COB-ID parameter of this PDO in the PDO communication objects. This parameter setting controls the COB-ID of the PDO communication, which is in 32 bits, and each bit with its meaning is given in the table follow.

Note: PM-4324-CPS supports CAN 2.0A only.

In the following table, it’s regarding the default PDO COB-ID parameters.

Note:

1. Users can also define the PDO COB-ID by themselves. Actually, all COB-ID can be

defined by users except the reserved COB-ID described in the table of the section

3.1. It is important to avoid the conflict with the defined COB-ID used in the same node.

2. The PDO COB-ID parameters cannot be changed if the PDO is valid (bit 31 =0).

7.2.2.2 Transmission Type

The transmission type is one of the several parameters defined in PDO communication objects with sub-index 02. Each PDO has its own transmission type. The transmission type can indicate the transmission or reception character for its corresponding PDO. The following table describes the relationship between the value of the transmission type and the PDO character. For example, if users used transmission type 0 for the first TxPDO, the CANopen device will follow the rule of the acyclic and synchronous PDO transmission.

Note:  The transmission type 1-240 indicates how many SYNC objects the TxPDO will be

triggered. The RxPDO is always triggered by the following SYNC upon reception of

data independent of the transmission types 0-240.  The transmission type 252 and 253 are only used for TxPDO. The transmission

type 252 means that the data is updated (but not sent) immediately after reception

of the SYNC object. For these two transmission types, the PDO is only transmitted

on remote transmission requests.  For the transmission types 254 and 255, the event timer will be used in the TxPDO.

The PDO, including the DI value, will be sent when the DI value is changed. And

both transmission types will directly trigger an update of the mapped data when

receiving the RxPDO.

7.2.2.3 PDO Communication Rule

The PDO related objects are indicated from index 0x1400 to 0x1BFF. For the PM-4324-CPS, RxPDO communication objects are not used. The ranges of the TxPDO communication objects and the mapping objects are from index 0x1800 to index 0x1813 and from index 0x1A00 to index 0x1A27 respectively. Moreover, each PDO communication object has its own PDO mapping object.

For example, the first TxPDO communication object is stored in the entry with index 0x1800, and the corresponding mapping object is stored in an entry with index 0x1A00. The object with index 0x1801 and the object with index 0x1A01 are a group, and so on. Therefore, before users access the practical data via PDO communication, each parameter for the PDO communications and mapping objects must be controlled.

Besides, only PDO communications can be used in the NMT operational state. Users can use the NMT module control protocol to change the NMT state of the PM-4324-CPS. It is described in the section 8.3.3. Besides, during communication via the PDO messages, the data length of the PDO message must match with the PDO mapping object. If the data length ‘L’ of the PDO message exceeds the total bytes ‘n’ of the PDO mapping object entries, only the first 'n' bytes of the PDO message are used by the PDO consumer. If ‘L’ is less than 'n', the PDO message will not be disposed by the PDO consumer, and an Emergency message with error code 8210h will be transmitted to the PDO producer. The PDO communication set is shown as follows.

COB-ID: the default PDO COB-ID, or the PDO COB-ID defined by users L: the data length about how many bytes the PDO message has PDO-msg: the real-time data or the data which can be mapped into the PDO mapping

objects

7.2.3 NMT Introduction

Error Control Protocol is a kind of the solution to check whether the CANopen device is still alive or not. And its related objects include 0x100C and 0x100D. The 0x100C is the guard time, and the 0x100D is the life time factor. The node life time is the guard time multiplied by the life time factor. The Node Guarding timer of the PM-4324-CPS will start to count after receiving the first RTR message for the guarding identifier. The communication set of the Error Control protocol is displayed below.

t: toggle bit

The value of this bit will be alternatively changed between two consecutive responses from the NMT slave. After the Node Guarding protocol becomes active, the value of the toggle-bit of the first response will be 0.

7.2.5 Object Dictionary of PM-4324-CPS

7.2.5.1 Communication Profile Area

The following tables are regarding each entry of the communication profile area is defined in PM-4324-CPS. For the convenient purpose, all communication entries are

divided into several tables. They are “General Communication Entries”, “TxPDO

Communication Entries”, and “TxPDO Mapping Communication Entries”.

Please note that in the table header with “Idx”, “Sidx” and “Attr” represent “index”,

“sub-index”, and “attribute” respectively. The sign “---” in the default field means that the

default is not defined or can be defined conditionally by the firmware built in PM-4324-CPS. In the table, the number accompanying letter “h” indicates that this value is in the hex format.

7.2.5.2 Manufacturer Specific Profile Area

In the following table, there is information about some special functions for the PM-4324-CPS. The index from 0x3200 to 0x3209 records the power meter measurement parameters. The number of these entries will be automatically updated when the PM-4324-CPS boot up. 0x320A is meter parameters information. 0x320B stores three meter parameters including Meter Ratio, PT Ratio and RT Ratio. PT Ratio means potential transformer ratio, the default value is 100 and the unit is 0.1. RT Ratio means current transformer ratio, the default value is 1 and the unit is 1.

Appendix: Questions & Answers

Q1. Can we use the other 5A CT’s (like 600/5) to directly connect to the input current

terminals of PM-4324 series?

No, because the input current is only mA size on PM-4324 series，definitely not to directly use other 5A CT’s to connect and apply（like100/5…）， It could causes the fetal damages. Users can use the PM-4324 series attached split type clip-on CT to connect the other CT’s secondary test 5A current.

Q2. If I want to replace the failed split type clip-on CT, can I just detach it? Anything I

should pay more attention to?

In any circumstance, please make sure the CT had been disconnected with the power cable of monitoring equipments before the CT lines detach from the terminals of the smart meter. Otherwise, it will cause the severe injury.

Q3. If the turn point of the split type clip-on CT has broken, or inner Ferrite-core has

broken, how to settle this condition?

The measure data will be not accuracy as before, please do not use any more. You need the new CT.

Q4. If multiple set of meters being installed，Can I detach the CT’s and mix use with

each other?

Please do not mix use，because each set of smart meter(PM-4324 series) and its attached split type clip-on CT are calibrated set by set. The mix use may cause the wrong measurements.

Q5. What problem is while the measured readings of the power consumption（kw）is

negative?

(1) First check the current input end – line terminal, （check the connection should be

CT1-K, CT1-L, CT2-K, CT2-L, CT3-K, CT3-L

）， base on white black, white black,

white black follow the sequence order

(2) Check the field current direction（K→L）is same as the inner arrow direction of the

split type clip-on CT.

(3) Confirm the RST (ABC) phase sequence.

Q6. What does negative kW on a motor/pump mean? Confirm the pump running at full load. Or are the readings taken at "idle" (negative kW, low power factor)?

Q7. PC and meter cannot make the connection with RS-485？

(1) Confirm the Modbus Address, default is 1. (2) Confirm the Band Rate, default is 19200. (3) Confirm the stop bit, default is 1. (4) Confirm the RS-485 connection, make sure the D+/D- is right. (5) Confirm the RS-485 master have to provide the bias for PM-4324 series. Otherwise,

the tM-SG4 or SG-785 should be added to provide the bias. All ICP DAS controllers and converters provide the bias.

Q8. What the power cable diameter (mm) of the monitoring equipments should be for

the various CT’s?

Power cable diameter ＜Φ10 use 60A CT，Φ10～Φ16 use 100A CT，Φ16～Φ24 use 200A CT，Φ36 use 300A CT，Φ36 use 400A CT

Q9. Regarding to the split type clip-on CT’s, if the wire is not long enough?

Φ10, Φ16, Φ24, Φ36 split type CT，the standard length is 4M. For special length, please contact ICP DAS.

Q10. How to measure the current large than 400A?

The CT of PM-4324 maximum range is 400A. If the target is more than 400A, we suggest the solution as follow.

For example the target is to measure maximum 800A current. We can measure big CT output and set a CT Ratio.

Note:

A. Primary CT accuracy will influence the measurement. B. Even primary CT output current max is 5A, please don’t wire to PM-4324 and PM-4324P

directly.

You need to choose primary current Transformers, please refer to

Q11. Can I use CT's that I currently own with PM-4324 Power Meter?

You can use CT's that you currently own with PM-4324P (without CTs) Power Meter. The CT inputs of the PM-4324P can handle a maximum of 333mV of AC current.

PM-4324P's current ratio is always full scale to 5A. CT ratio can be set internally to work with up to 1200 amp CTs.

Adding current transformer (333mV Output CTs) has the effect of reducing the measured current by the CT ratio (let's say 40:1 for 200A CT as example). So a current of 200A becomes 5A. Since the meter sees 5A, many of the measurements it reports will be low by a factor of 4 unless they are scaled up by 4.

Note:

A. Please use low phase angle error CTs: essential for accurate power and energy

measurements. (Example: phase error <2°) B. Accuracy may be 5% or greater without calibration with power Meter. C. Primary CT accuracy will influence the measurement.

D. PM-4324P only for external 333mV Output CTs.

Safe: burden resistor built-in, 333 mVac voltage output at rated full scale current, no

shorting blocks needed. E. This meter requires external CT(s) to operate:

1P2W-1CT requires 1 CT per meter.

3P3W-2CT/1P3W-2CT requires 2 CTs per meter.

3P4W-3CT/3P3W-3CT requires 3 CTs per meter.

Q12. What is the difference between line to line voltages to line to ground voltage?

On a three phase wye connected system line to line voltages will be the voltages between the terminals A - B, B - C, A - C. On a three phase wye connected system line to ground voltages will be the voltages between the terminals A - N, B - N, C - N. To calculate the line to ground voltages divide the line voltage by the square root of three which equals 1.73. An

example, on a 380 volt wye system, line to line voltage is 380 volts and line to ground voltage is 380/1.73 = 220 volts

Q13. How about the harmonic (THD) analysis capability?

The number of harmonics N that can be analyzed within the 2.8 kHz pass band is the whole number of 2800/f. The absolute maximum number of harmonics accepted by the Energy Metering IC is 63.

N = [2800/f], N ≤ 63

Q14. How to measure the Voltage large than 500V?

For service voltage above 600 Vac, voltage transformers (PTs) are used to step down the voltage to a lower range that will work with a PM-4324 meter.

Selecting a Transformer: Selecting the right voltage transformer is simple. Review the following

considerations to determine the best fit for your application.

Input Voltage: Select a transformer that will operate on the supply voltage available at your facility (Example: PRI. Voltage 720V; SEC. Voltage 120V). Check the connection diagram (three-phase Y and delta; phase sequence) to ensure compatibility. Adding potential transformers has the effect of reducing the measured line voltage by the PT ratio (let's say 6:1 for this example). So a voltage of 720 Vac becomes 120 Vac. Since the meter sees 120 Vac, many of the measurements it reports will be low by a factor of 6 unless they are scaled up by 6.

Frequency: If you are operating in the United States, you will most likely be operating on 60 Hz. However should you need a 50 Hz rated transformer.

Accuracy: Transformer (PT) accuracy (Example: 1% or 3%) will influence the measurement. Rated Output (VA): Example: 150 VA (50VA per phase).

Q15. How to set up [Display Voltage] register value to correctly display line to ground voltage or line to line voltage?

Line to Ground Voltage

Line to Line Voltage

3P3W-2CT

[Display Voltage] = 1 (Show as Vln)

[Display Voltage] = 0 (Automatic)

3P3W-3CT

[Display Voltage] = 0 (Automatic)

[Display Voltage] = 2 (Show as Vll)

3P4W-3CT

[Display Voltage] = 0 (Automatic)

[Display Voltage] = 2 (Show as Vll)

The voltage [V_x] register in Modbus register table can be used to show line-to-ground voltage or line-to-line voltage value by setting [Display Voltage] register value. According to different wiring types, it is required to set different [Display Voltage] value. If the voltage is not displayed as expected value, please refer to the table below and check if the setting value is set accurately.
