Throughout this document, the phase-to-neutral notations of A/B/C and L1/L2/L3 as well as the phaseto-phase notations of AB/BC/CA and L12/L23/L31 may be used interchangeably for specifying a certain parameter to be a phase-to-neutral or phase-to-phase value, respectively.
The following sections illustrate the available measurements for each display option. Depending on the Wiring Mode selected, certain measurements may not be available. For example, the per-phase ULN, ULN Average, I4, per-phase P, Q, S, PF and per-phase Energy measurements (available in FW V1.01.00 or later) are not available when the Wiring Mode is set to 3P3W or 1P2W L-L.

4.1 Inputs and Outputs 4.1.1 Digital Inputs
The PMC-53A-E comes standard with four self-excited Digital Inputs that are internally wetted at 24 VDC with a sampling frequency of 1000Hz and programmable debounce. The PMC-53A-E provides the following programmable functions for its Digital Inputs:
1) Digital Input
The digital inputs are typically used for status monitoring which can help prevent equipment damage, improve maintenance, and track security breaches. The real-time statuses of Digital Inputs are available on the Front Panel LCD Display as well as through communications. Changes in Digital Input status are stored as events in the SOE Log in 1 ms resolution.
2) Pulse Counting
Pulse counter is supported with programmable Pulse Weight and facilitates WAGES (Water, Air, Gas, Electricity and Steam) information collection.
3) Tariff Switching
Up to 3 Digital Inputs may be used to select to which of the 8 Tariffs the energy consumption should be accumulated. The 3 Digital Inputs (DI1, DI2 and DI3) represent 3 binary digits where Tariff 1=000, Tariff 2=001, …, Tariff 8=111 where DI1 represents the least significant digit and DI3 represents the most significant digit. The DI1 Function setup register must first be programmed as a Tariff Switch before configuring DI2 with the same function. In other words, if DI1 is configured as a Digital Input or Energy Pulse Counter and DI2 is configured as a Tariff Switch, the TOU will continue to function based on the TOU Schedule.
The following table describes the DI’s setup parameters:

4.1.2 ډیجیټل پایلې
The PMC-53A-E comes standard with two Form A Electrometrical Relays. Digital Outputs are normally used for setpoint alarming, load control, or remote control applications.
Digital Outputs on the PMC-53A-E can be used in the following applications:
1) Front Panel Control
Manually operated from the Front Panel. Please refer to the DO Control setup parameter in Section 3.1.3 for a detailed description.
2) ریموٹ کنټرول
Remotely operated over communications via our free PMC Setup software or PecStar® iEMS Integrated Energy Management System.
3) Control Setpoint
Control Setpoints can be programmed to trigger DO action upon becoming active. Please refer to Section 4.4 for a detailed description.
Since there are multiple ways to trigger the Digital Outputs on the PMC-53A-E, a prioritized scheme has been developed to avoid conflicts between different applications. In general, Front Panel Control has the highest priority and can override other control schemes. Remote Control and Control Setpoint share the same priority, meaning that they can all be programmed to control the same Digital Output. This scheme is equivalent to having an implicit Logical OR operation for the control of a Digital Output and may be useful in providing a generic alarm output signal. However, the sharing of a Digital Output is not recommended if the user intends to generate a control signal in response to a specific setpoint condition.

CET Electric Technology
4.1.3 Energy Pulse Outputs (Optional)
The PMC-53A-E comes standard with one Front Panel LED Pulse Output for energy pulsing and can be equipped with two optional Solid State Digital Outputs for kWh and kvarh pulsing, replacing the default Digital Outputs. Energy Pulse Outputs are typically used for accuracy testing. Energy Pulsing via the Front Panel LED can be enabled from the Front Panel through the LED EN Pulse setup parameter. The pulse constant can be configured as 10/100/1000/3200/5000/6400/10000/25000 impulses per kWh/kvarh through the EN Pulse CNST setup parameter.
Note: The constant 10/100/5000/10000/25000 are supported in the Firmware V2.00.00 and later.
4.1.4 Analog Input (Optional)
The PMC-53A-E comes optionally with an Analog Input which can be programmed as 0mA to 20mA or 4mA to 20mA input. There are 3 setup parameters:
Type: Select between 0-20mA or 4-20mA input. AI Zero: This value corresponds to the minimum Analog Input of 4 mA (for 4-20mA input) and has
a range of -999,999 to +999,999. AI Full: This value corresponds to the maximum Analog Input of 20 mA and has a range of –
999,999 to +999,999. For example, to measure the oil temperature of a transformer, connect the outputs of the temperature sensor to the AI terminals of the PMC-53A-E. The temperature sensor outputs 4mA when the temperature is -25°C and 20mA when the temperature is 100°C. As such, the Type parameter should be programmed as 4-20mA. The AI FULL parameter should be programmed with the value of 100, and the AI ZERO parameter should be programmed with the value of -25. Therefore, when the output of the sensor is 20mA, the reading will be 100.00°C. When the output is 4mA, the reading will be -25.00°C. When the output is 12mA, the reading will be (100°C – (-25°C)) x (12mA-4mA) / (20mA-4mA) + (-25°C) = 37.50°C.
4.1.5 IR Input (Optional)
The PMC-53A-E comes optionally with one IR input for Residual Current measurement via an external Residual Current transformer. The IR measurement can be set as the Setpoint Source to trigger an alarm when a threshold value is exceeded. The 3-Phase and Neutral conductors should be wired through the Residual Current CT without the PE (Protective Earth) wire as illustrated below.

1) When the Wiring Mode is 3P3W, the per-phase ULN, P, Q, S and Power Factor are reserved. 2) The Ung and Ing measurements are valid only when the Wiring Mode is 3P4W. 3) The Frequency detection priority is: U1 (U12) > U2 (U23) > U3 (U31). For example, if U1=0, the U2 signal would be used for
Frequency detection instead. If both U1 and U2 are 0, the U3 signal would be used for Frequency detection.
4.2.2 د انرژي اندازه کول
The PMC-53A-E provides Energy parameters for active energy (kWh), reactive energy (kvarh) and apparent energy (kVAh) with a resolution of 0.1k and a maximum value of ±100,000,000.0 kXh. When the maximum value is reached, the energy registers will automatically roll over to zero. The Real-time energy can be reset manually through the Front Panel or via communications.
The PMC-53A-E provides the following energy measurements:
Per-Phase & 3-Phase

kvarh Import/Export/Net/Total kvarh Import/Export of TOU T1-8 kvarh of Q1/Q2/Q3/Q4 kVAh kVAh of TOU T1-8
Table 4-3 Energy Measurement
4.2.3 Interval Energy Measurements
The PMC-53A-E provides Interval Energy measurements of kWh Import/Export, kvarh Import/Export and kVAh. The Interval Energy measurements represent the amount of energy consumed during the last completed interval as defined by EN Period. The Interval Energy Measurements can only be retrieved through communications and are not available on the Front Panel or Web انٹرفیس.
The Interval Energy Period (EN Period) setup parameter can be programmed from the Front Panel, Web Interface or through communications and allows the user to specify the interval for which the real-time energy consumption should be accumulated. Please note that changing the Interval Energy Period would clear the present Interval Energy measurements.
4.2.4 Demand Measurements
Demand is defined as the highest average power consumption over a fixed interval (usually 15 minutes) within the billing period. The PMC-53A-E provides Present and Predicted Demand for P /Q/ S Total, 3Phase ULL, ULN, Currents and Average updated once a second, as well as Max. Demand (See Section 4.5.2) in This Month (Since Last Reset) and Last Month (Before Last Reset). Predicted Demand is typically used for pre-alarming and to help users reduce power consumption using a Setpoint to warn that the Demand limit may be exceeded.
The PMC-53A-E provides the following setup parameters:

For example, the value 1512 means that the Self-Read will take place at 12:00pm on the 15th day of each month. · A 0xFFFF value will disable the Self-Read operation and replace it with manual operation. A manual reset will cause the Max. Demand of This Month to be transferred to the Max. Demand of Last Month and then reset. The terms This Month and Last Month will become Since Last Reset and Before Last Reset. The Predicated Response shows the speed of the predicted demand output. A value between 70 and 99 is recommended for a reasonably fast response. Specify a higher value for higher sensitivity.

4.2.5 Reactive Energy Monitoring
This feature is only available in Firmware V1.01.00 or later.
In many countries, there is often a penalty for over Reactive Energy consumption. The PMC-53A-E has implemented the following parameters to help monitor both kvarh Import and kvarh Export as a percentage of kWh Import on a daily basis as well as the running total from the last 30 days.
The following is a list of parameters calculated by the PMC-53A-E for the purpose of monitoring the rate of kvarh (Import and Export) consumption relative kWh Import:

Table 4-5 Reactive Energy Monitoring Parameters
The above parameters are updated daily at 00:00 based on yesterday’s P Imp., Q Imp. and Q Exp. An internal circular buffer is used to accumulate a 30-day running total of P Imp., Q Imp. and Q Exp., based on the sliding window calculation, to arrive at the 30D Total %(Q Imp./P Imp.) and 30D Total % (Q Exp./P Imp.) values. The Daily and 30D Total %(Q Imp./P Imp.) are available on the Front Panel, Web Interface and via communications. Also, the internal buffer for the 30-day running total calculation can be reset via the Front Panel, Web Interface and Communications.
The PMC-53A-E can further be configured to generate a Setpoint alarm for Daily %(Q Imp./P Imp.) and/or Daily %(Q Exp./P Imp.) and trigger an email if so desired on a daily basis to alert the customers if they have exceeded their Reactive Energy quota the previous day so that appropriate measure can be taken to correct their consumption trend. Please refer to 4.4 Setpoints for more information.
4.3 Power Quality 4.3.1 Phase Angles
Phase analysis is used to identify the angle relationship between 3-phase Voltages او جریان.
For WYE connected systems, the per phase difference of the Current and Voltage angles should correspond to the per phase PF. For example, if the PF is 0.5 Lag and the Voltage phase angles are 0.0°, 240.0° and 120.0°, the Current phase angles should have the values of -60.0°, 180.0° and 60.0°.

4.3.4 Frequency and Voltage Deviations
The PMC-53A-E with Firmware V2.00.00 or later is capable of measuring Frequency Deviation and Voltage Deviation. The Deviation measurement can be accessed via web interface or through communications.
The PMC-53A-E computes Freq. Deviation as per below:
Freq. Deviation = f – fnominal
where fnominal is the Nominal Frequency The PMC-53A-E provides the ability to capture Voltage Deviation as per below:
For the ULN: If Upu < 100
ULN Underdeviation = 100 – Upu ULN Overdeviation=0 If Upu > 100 ULN Underdeviation =0 ULN Overdeviation = 100 – Upu
where Upu=100ULN3
For the ULL: If Upu < 100
ULL Underdeviation = 100 – Upu ULL Overdeviation=0 If Upu > 100 ULL Underdeviation =0 ULL Overdeviation = 100 – Upu
where Upu=100ULL

4.5.3 Monthly Energy Log
The PMC-53A-E stores monthly energy data for the present month and the last 12 months. The Monthly Energy Log Self-read Time setup parameter allows the user to specify the time and day of the month for the Recorder’s Self-read operation via communications. The Monthly Energy Logs are stored in the meter’s non-volatile memory and will not suffer any loss in the event of power failure, and they are stored on a First-In-First-Out basis where the newest log will overwrite the oldest.
The Monthly Energy Log Self-Read Time supports two options: A zero value means that the Self-Read will take place at 00:00 of the first day of each month.
A non-zero value means that the Self-Read will take place at a specific time and day based on the formula: Energy Self-Read Time = Day x 100 + Hour where 0 Hour 23 and 1 Day 28. For example, the value 1512 means that the Self-Read will take place at 12:00pm on the 15th day of each month.
The Monthly Energy Logs can be reset manually through the front panel or via communications.
The PMC-53A-E provides the following energy data for the present month and the last 12 months:

4.5.4 Daily and Monthly Freeze Log
The PMC-53A-E provides a Daily Freeze Log and a Monthly Freeze Log for Energy and Demand parameters and can store up to 60 daily freeze records (2 months) and 36 monthly freeze records (3 years). All Freeze Logs and their respective setup registers can only be accessed through communications. The PMC-53AE’s Freeze Logs can freeze and record the following parameters:
Freeze Type Daily Freeze

The Daily Self-Read Time setup parameter allows the user to specify the time of the day for the Daily Freeze Log Self-Read operation, while the Monthly Self-Read Time setup parameter allows the user to specify the time and day of the month for the Monthly Freeze Log Self-Read operation.
1) Daily Freeze Self-Read Time can be set to a zero value or a non-zero value:
· A zero value means that the Self-Read will take place at 00:00 every day. · A non-zero value means that the Self-Read will take place at a specific time of the day based on
the formula: Self-Read time = (Hour x 100 + Min) where 0 Hour 23 and 0 Min 59. For example, the value 1512 means that the Self-Read will take place at 15:12 of each day.
2) Monthly Freeze Self-Read Time can be set to a zero value or a non-zero value:
· A zero value means that the Self-Read will take place at 00:00 of the first day of each month. · A non-zero value means that the Self-Read will take place at a specific time and day based on the
formula: Monthly Self-Read Time = Day x 100 + Hour where 0 Hour 23 and 1 Day 28. For example, the value 1512 means that the Self-Read will take place at 12:00pm on the 15th day of each month.
4.5.5 SOE Log
The PMC-53A-E’s SOE Log can store up to 100 events such as Power-on, Power-off, Digital Input status changes, Digital Output status changes, Setup changes and Setpoint events in its non-volatile memory. Each event record includes the event classification, its relevant parameter values and a timestamp in ±1 ms resolution. The SOE Log can be displayed on the Front Panel or Web Interface or retrieved via communications for display. If there are more than 100 events, the newest event will replace the oldest event on a First-In-First-Out basis. The SOE Log can be reset from the Front Panel or via communications.
4.5.6 Data Recorder (DR) Log
The PMC-53A-E provides five Data Recorders capable of recording a maximum of 16 parameters each with a minimum recording interval of 60s. The Data Recorder Log is stored in the device’s non-volatile memory and will not suffer any loss in the event of a power failure.
Hardware V1 and Firmware V1.00.00.
The PMC-53A-E’s 4MB log memory is divided equally into 5 buffers of 800kB each. By default, each DR is allocated one 800kB buffer, which can hold a maximum ~118 days of recording with 16 parameters at 15minute interval. This is equivalent to having a Recording Depth of ~11,377 data records (~118 days x 24 hours per day x 4 data records per hour).
The Data Recorder can be configured to use more than one 800kB buffer if it’s required to maintain recording for a longer period of time. For example, if the entire 4MB log memory is used for a single Data Recorder, it can be configured to hold a maximum of 592 days (1.62 years) of recording with 16 parameters at 15-minute interval. This is equivalent to having a Recording Depth of 56,888 data records (592 days x 24 hours per day x 4 data records per hour). In order to do this, it’s necessary to free the log
58
CET Electric Technology
memory occupied by Data Recorders #2 to #5 by setting their respective Number of Parameters and Recording Depth setup parameters to 0.
The PMC-53A-E’s Data Recorder has been enhanced such that it can support a maximum Recording Depth of 120,000 records (compared to the max. of 10,000 in PMC-53A), which is equivalent to 1250 days (~3.4 years) of recording at 15-minute interval. However, only one Data Recorder can be configured with a maximum of 6 parameters and 120,000 records.
The following formula can be used to calculate how many bytes would be required for a single record with n parameters where 0 n 16.
No. of Bytes per Record = n x 4 + Timestamp @ 8 bytes
With 16 parameters, the no. of bytes required = 16 x 4 + 8 = 72 bytes. If a Data Recorder is allocated a single 800kB buffer, its Recording Depth = 800kB / 72 bytes = 11,377 records.
It should be noted that the above calculation is used to illustrate the internal organization of the data storage and is only an approximation of the actual implementation. The following table defines how many records are actually available for the different number of parameters in each 800kB buffer.
No. of Parameters 1 2 3 4 5 6 7 8
No. of Records 68,200 51,200 40,800 34,000 29,200 25,600 22,600 20,400

Firmware V1.01.00 or later
The total available log memory of the PMC-53A-E has been increased to 8MB and is equally divided into 1600kB for each Data Recorder. A maximum Recording Depth of 110,000, equivalent to 1145 days (~3.14 years), can be configured for one Data Recorder with 16 parameters at 15-minute recording interval.
Hardware V2 and Firmware V2.00.00 or later
The total available log memory of the PMC-53A-E has been increased to 16MB and is equally divided into 3200kB for each Data Recorder. A maximum Recording Depth of 120,000, equivalent to 1250 days (~3.42 years), can be configured for one Data Recorder with 16 parameters at 15-minute recording interval. In order to do that, it’s necessary to free up sufficient buffer occupied by other DR groups. Please note that modifying the Recording Depth of one group will clear the recorded DR Logs and reset their Log Pointers.
The programming of the Data Recorder is only supported over communications. Each Data Recorder provides the following setup parameters:
Setup Parameters Trigger Mode Recording Mode Recording Depth Recording Interval Offset Time Number of Parameters Parameter 1 to 16
Value/Option 0=Disabled / 1=Triggered by Timer 0=Stop-When-Full / 1=First-In-First-Out 1 to 120,000 (entry) 60 to 3,456,000 seconds 0 to 43,200 seconds, 0 indicates no offset 0 to 16 See Appendix A for a complete list of parameters Table 4-13 Setup Parameters for Data Recorder
ډیفالټ 1 1
See Appendix B 900 s 0
See Appendix B See Appendix B
The Data Recorder Log is only operational when the values of Trigger Mode, Recording Depth, Recording Interval, and Number of Parameters are all non-zero.
The Recording Offset parameter can be used to delay the recording by a fixed time from the Recording Interval. For example, if the Recording Interval parameter is set to 3600 (hourly) and the Recording Offset parameter is set to 300 (5 minutes), the recording will take place at 5 minutes after the hour every hour, i.e. 00:05, 01:05, 02:05, etc. The value of the Recording Offset parameter should be less than the Recording Interval parameter.

4.6 Time of Use (TOU)
TOU is used for electricity pricing that varies depending on the time of day, day of week, and season. The TOU system allows the user to configure an electricity price schedule inside the PMC-53A-E and accumulate energy consumption into different TOU tariffs based on the time of consumption. TOU programming is only supported through communications.
The TOU feature on PMC-53A-E supports two TOU schedules, which can be switched at a pre-defined time. Each TOU schedule supports:
Up to 12 seasons 90 Holidays or Alternate Days 20 Daily Profiles, each with 12 Periods in 15-minute interval 8 Tariffs
Instead of using the TOU schedule to switch between Tariffs, the PMC-53A-E supports Tariff switching based on the status of DI1 to DI3.
The 3 Digital Inputs (DI1, DI2 and DI3) represent 3 binary digits where Tariff 1=000, Tariff 2=001, Tariff 3=
010, …, Tariff 7=110 and Tariff 8=111 where DI1 represents the least significant digit and DI3 represents
the most significant digit. As soon as DI1, DI2 and/or DI3 are configured as Tariff Switches, the current
TOU Tariff will be determined by the status of the DIs, and the TOU Schedule will be ignored. The DI1 Function setup register must first be programmed as a Tariff Switch before configuring DI2 and DI3 with
the same function. In other words, if DI1 is configured as a Digital Input or Energy Pulse Counter, and DI2 is configured as a Tariff Switch, the TOU will continue to function based on the TOU Schedule. The number
of Tariffs supported depends on how many DIs are programmed as a Tariff Switch as indicated in the following table.

4.7.3 Ethernet Gateway
The PMC-53A-E’s Ethernet Gateway feature supports Modbus communications between the Master Software (e.g. PecStar iEMS) on a Local Area Network and other RS-485-enabled devices (e.g. PMC-53A) via the PMC-53A-E’s Ethernet (P2) and RS-485 port (P1). This eliminates the need for an additional, external Ethernet-to-RS-485 Gateway, simplifies the overall network design and saves cost. The Master Software sends a “Modbus RTU over TCP/IP” packet (Modbus RTU packet, i.e. the payload, encapsulated in a TCP/IP frame) to the PMC-53A-E’s Ethernet port at its IP Address and IP Port No. 6000. The PMC-53A-E receives this “Modbus RTU over TCP/IP” packet at its Ethernet port, extracts the “encapsulated” Modbus RTU packet, i.e. the payload, from the TCP/IP frame and then in turn forwards it to its RS-485 port (P1). The RS-485-enabled device receives the Modbus RTU packet and sends its response back to the PMC-53A-E, which in turn encapsulates the Modbus RTU response packet in a TCP/IP frame, sends it back to the Master Software over Ethernet and completes the transaction. The following illustrates the steps of configuring the PMC-53A-E’s Ethernet Gateway:
1) Go to Setup-> Comm.-> RS-485 (P1) to change the Protocol setup parameter from the default setting of Modbus to Gateway, either via the Web Interface or Front Panel.
62
CET Electric Technology
Figure 4-8 Select “Gateway” Mode on Web Server 2) Connect the RS-485-enabled devices (i.e. PMC-53A) to the RS-485 port (P1) of the PMC-53A-E.
Figure 4-9 Typical Application for Ethernet Gateway 3) Configure the Master Software (e.g. PecStar iEMS) on the WorkStation to communicate with the
RS-485-enabled devices via PMC-53A-E’s Ethernet port at IP port No. 6000. It should be noted that the Master Software must support the Modbus RTU over TCP/IP protocol for this to work. 4) Make sure the serial port settings such as Baud Rate and Data Format are identical between the PMC-53A-E’s RS-485 port and the RS-485-enabled devices. 5) The Master Software should be able to communicate with the RS-485-enabled devices via the PMC-53A-E’s Ethernet Gateway, providing that all the necessary configuration is correct.
4.8 تشخیص
The PMC-53A-E provides wiring error detection for 3P4W and 3P3W wiring modes and allows the user to check for potential problems, especially during the initial commissioning stage. The following wiring errors may be detected: Frequency Out-of-Range Voltage/Current Phase Loss Incorrect Voltage and Current Phase Sequence P Direction per phase and Total Possible Incorrect CT Polarity Disconnection of Residual Current Input Please note that the error detection above is based on the following assumptions: The Voltage and Current Phase Sequences are consistent P is P Import, which means the P is over 0
63
CET Electric Technology
3P4W wiring mode supports all detections
3P3W wiring mode does not support the detection of Voltage Phase Loss, P Direction per phase and
CT Polarity

Table 5-3 Data Format for 0x05 Execute Request/Response Packet
The PMC-53A-E adopts the ARM before EXECUTE operation for the remote control of its Digital Outputs if this
65
CET Electric Technology
function is enabled through the Arm Before Execute Enable Setup register (40301), which is enabled by default. Before executing an OPEN or CLOSE command on a Relay Output, it must be “Armed” first. This is achieved by writing the value 0xFF00 to the appropriate register to “Arm” a particular DO operation. The DO will be “Disarmed” automatically if an “Execute” command is not received within 15 seconds after it has been “Armed”. If an “Execute” command is received without first having received an “Arm” command, the meter ignores the “Execute” command and returns the 0x04 exception code.

7. The PMC-53A-E has one SOE Log and five DR Logs. Each of these logs has a Log Pointer that indicates its current logging position. The range of the Log Pointer is between 0 and 0xFFFFFFFF, and it is incremented by one for every new log generated and will roll over to 0 if its current value is 0xFFFFFFFF. A value of zero indicates that the SOE or DRx does not contain any Log. If a Clear Log is performed via communications, its Log Pointer will be reset to zero and immediately incremented by one with a new “Clear SOE via Communications” event. When the number of events is larger than the Log Depth, only the latest 100 SOE Logs (up to 120000 DR Logs) will be stored on a FIFO basis.
Use the following equation to determine the latest log location: Latest Log Location = Modulo [Log Pointer/Log Depth] where Log Pointer may be one of the following: SOE Log Pointer, DR1 – DR5 Log Pointers and Log Depth is as follows: SOE Log Depth = 100 (fixed) DRx Log Depth = DRx Recording Depth (see Section 5.13.5 Data Recorder Setup)
