4.1 Inputs and Outputs

4.1.1 Digital Inputs

The PMC-592 provides two or optionally four self-excited Digital Inputs (DIs) that are internally wetted

at 24 VDC. DIs are typically used for monitoring external status which can help prevent equipment

damage, improve maintenance, and track security breaches. The real-time statuses of the DIs are

available on the Web Interface, HMI as well as through communications. Changes in DI status are stored

as events in the SOE Log in 1 ms resolution. Each DI has the following setup parameters:

Table 4-1 Definition for DI Parameters

In addition, the PMC-592 can be configured for monitoring the breaker status for each Branch Circuit

via the external DI module such as PMC-521D in Firmware V1.00.03 or later. Up to 4 DI Modules (or

PMC-521D) may be connected where each PMC-521D can be used for monitoring 21 breaker status of

each Branch Input. The breaker status is read by the PMC-592 over RS485 (P2) when the P2 Operation

Mode is set to External DI Module. Each DI Module has the following setup parameters which can be

programed via the Web interface, HMI or through communication:

Self-Read Time

(Reg. # 6021)

The Self-Read Time allows the user to specify the time and day of the month for the Demand Log Self-Read operation. At the specified time in each month, the Max Demand of This Month is transferred to the Max Demand of Last Month and then reset. The 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: Self-Read Time = Day * 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.

volatile memory and will not suffer any loss in the event of a power failure.

The PMC-592 supports the sliding window demand calculation and has the following setup parameters:

Table 4-7 Demand Setup Parameters

The PMC-592 provides the following Demand and Max Demand parameters:

* Available in Firmware V1.00.04 or later

Table 4-8 Demand Parameters

Notes:

1) The Mains or SMx Max Demands can be reset manually through communications, the built-in Web Interface or the optional

HMI.

4.3 Alarm Setpoints

The PMC-592 provides powerful alarming functions for the Mains and Branch Inputs as well as for

different parameters. Each Alarm Type has an independent enable switch, which allows the alarms for

Mains-I, Mains-II and Branch to be enabled separately as needed. The alarms may also be disabled by

setting the alarm threshold to 0.

4.3.1 Alarm Status

The PMC-592 supports both the Instantaneous Alarm and Latched Alarm, which are defined below.

The Instantaneous Alarm becomes Active when the alarm condition is met and is automatically reset to

NORMAL when the alarm condition is no longer met. Instantaneous Alarm cannot be reset manually.

Latched Alarm

On the other hand, the Latched Alarm becomes Active when the alarm condition is met and will remain

in the ALARM state even after the alarm condition is no longer met. The Latched Alarm must be reset

manually. However, the Latched Alarm cannot be reset while the alarm condition remains.

4.3.3 Universal Hysteresis and Current ON/OFF Status

The Universal Hysteresis is a global parameter that is valid for all alarms except Dip/Swell and

Interruption alarms, which have their own Hysteresis parameters. The Current ON Threshold, Current

ON Delay and Current OFF are global parameters that are valid for all Mains and Branch Inputs.

Table 4-10 Global Parameters

The Universal Hysteresis is a global parameter that is used to prevent an alarm from fluctuating between

the Active and Inactive states around the threshold point.

It should be noted that the Current ON Limit is calculated based on the Breaker Rating parameters.

Therefore, it’s critical to set the Breaker Rating correctly for each Current channel for the Current

Alarms to work properly.

Current ON Limit = Channel’s Breaker Rating x Current On Threshold (%)

Current OFF Limit = Current ON Limit x (1 - Universal Hysteresis)

The PMC-592 provides an internal Current ON/OFF status for each Current channel to indicate whether

the channel is ON (Loaded) or OFF (No Load). If the channel status is OFF and has never been ON, it

means that the channel has no load and would prevent the Low and Low-Low alarms from activating.

In Firmware V1.00.10 or later, the Current OFF Alarm Enable parameter (Modbus Register 6394) has

been added to ensure that the Current L/LL Alarms would remain Active even when the Current

transitions from the ON to OFF state if Current OFF Alarm Enable is enabled. The Current L/LL Alarms

would be reset only if the Current returns to the ON state. For Firmware V1.00.09 or earlier, the Current

L/LL Alarms would be reset immediately when the Current transitions from the ON to OFF state, similar

to having the Current OFF Alarm Enable parameter disabled.

The following figures illustrate the logic diagram of the Current ON/OFF status, respectively.

4.3.4 Current Alarms

PMC-592 provides four Current alarm levels (High-High, High, Low, Low-Low) for the Mains and Branch

Currents as well as the associated Current Demands with Time Delay parameters.

It should be noted that the Alarm Limit is calculated based on the Breaker Rating parameters. Therefore,

it’s critical to set the Breaker Rating correctly for each Current channel for the Current Alarms to work

properly.

Channel Alarm Limit = Channel’s Breaker Rating x Alarm Threshold (%)

For High and High-High Alarms, which are conceptually similar to Over Setpoint:

Channel Alarm Return Limit = Channel Alarm Limit x (1 – Universal Hysteresis)

For Low and Low-Low Alarms, which are conceptually similar to Under Setpoint:

Channel Alarm Return Limit = Channel Alarm Limit x (1 + Universal Hysteresis)

and Mains-II Voltage Alarms will be evaluated against their respective Mains-I/II PT Secondary

(ULL) values. Also, the Nominal Voltage will be adjusted internally for the ULN and ULL Alarms

accordingly, where ULL-I/II Nominal Voltage = Mains-I/II PT Secondary and ULN-I/II Nominal

Voltage = Mains-I/II PT Secondary ÷√3.

Therefore, it’s critical to set the Nominal Voltage correctly for the Voltage ON/OFF Status, Voltage

Alarms, as well as the Dip/Swell and Interruption Alarms (discussed in Section 4.3.12) to work properly.

Voltage-I/II ON Limit = Mains-I/II Nominal Voltage x 10%

4.3.6 Power and Power Factor Alarms

PMC-592 provides an internal Power On/OFF status as well as two Power Alarm levels (High and Low).

The Power H/L Alarms will only be evaluated if it’s determined that the Power ON status is TRUE. The

Power and Power Factor Alarms only apply to the Mains Inputs.

It should be noted that the Power Alarm On and Power Alarm Threshold are calculated based on the

Nominal Voltage, Breaker Rating and Current ON Threshold parameters. Therefore, it’s critical to set

these parameters correctly for the Power ON and Power Alarms to work properly.

a) For Firmware V1.00.09 or earlier

Power Alarm ON Limit = Channel Breaker Rating x Nominal Voltage x 3 x Current ON Threshold

Power H/L Alarm Limit = Channel Breaker Rating x Nominal Voltage x 3 x Power H/L Alarm Threshold

where Nominal Voltage = Nominal ULN Voltage (Modbus Register 6001)

b) For Firmware V1.00.10 or later

Power Alarm ON Limit = Channel Breaker Rating x (Nominal Voltage ÷√3) x 3 x Current ON Threshold

Power H Alarm Limit = Channel Breaker Rating x (Nominal Voltage ÷√3) x 3 x Power H Alarm Threshold

Power L Alarm Limit = Channel Breaker Rating x (Nominal Voltage ÷√3) x 3 x Power L Alarm Threshold

where Nominal Voltage = Mains-I/II PT Secondary (ULL Voltage) (Modbus Registers 6043 and 6046)

Power OFF Limit = Power ON Limit x (1 – Universal Hysteresis)

Power H Alarm Return Limit = Power H Alarm Limit x (1 – Universal Hysteresis)

4.3.12 Dip, Swell and Interruption Alarm

The PMC-592 with Firmware V1.00.05 or later supports Dip/Swell and Interruption Alarms according to

IEC 61000-4-30 with 1-cycle update instead of ½ -cycle as specified by the standard. The following table

illustrates the Dip/Swell and Interruption Alarm parameters and their respective default values.

It should be noted that the Dip/Swell/Interruption Alarm Limits are calculated based on Nominal

Voltage, which is defined as the

a) Nominal ULN Voltage (Modbus Register 6001) in Firmware V1.00.09 or before. b) Mains-I/II PT Secondary (ULL) (Modbus Registers 6043 and 6046, respectively) in Firmware

V1.00.10 or later, replacing Nominal ULN Voltage in pervious Firmware versions. The Mains-I

Table 4-19 Dip/Swell Alarm Parameters

Page 95

and Mains-II Dip/Swell/Interruption Alarms will be evaluated against their respective Mains-

I/II PT Secondary (ULL) values. Also, the Nominal Voltage will be adjusted internally for Wye

and Delta modes accordingly, where ULL-I/II Nominal Voltage = Mains-I/II PT Secondary and

ULN-I/II Nominal Voltage = Mains-I/II PT Secondary ÷√3.

Therefore, it’s critical to set the Nominal Voltage correctly for the Dip/Swell/Interruption Alarms to work

properly.

Dip/Swell/Interruption Alarm Limit = Nominal Voltage x Dip/Swell/Interruption Alarm Threshold

Dip/Interruption Alarm Return Limit = Dip/Interruption Alarm Limit x (1 + Universal Hysteresis)

Swell Alarm Return Limit = Swell Alarm Limit x (1 – Universal Hysteresis)

Total Demand Distortion (TDD)

TDD the ratio of the root mean square (rms) of the harmonic current to the root mean square value of

the rated or maximum demand fundamental current, expressed as a percent.

TDD of the current I is calculated by the formula below:

where

IL = maximum demand of fundamental current which calculated via FFT (Fast Fourier

Transform)

h = harmonic order (1, 2, 3, 4, etc.)

= rms load current at the harmonic order h

K-Factor and Crest Factor

K-factor is defined as the weighted sum of the harmonic load currents according to their effects on

transformer heating, as derived from ANSI/IEEE C57.110. A K-Factor of 1.0 indicates a linear load (no

harmonics). The higher the K-Factor, the greater the harmonic heating effects.

The calculation method of K-Factor is listed below:

Ih = hth Harmonic Current in RMS

= Highest harmonic order

h = Harmonic order

Crest Factor is defined as the Peak to Average Ratio (PAR), and its calculation is listed below:

4.4.3 Supply Voltage Dips/Swells and Interruptions

The PMC-592 supports the detection of the Supply Voltage Dip/Swell and Interruption using a method

that is in accordance with Section 5.4 of IEC 61000-4-30 Power Quality Standard for Class A performance

since Firmware V1.00.05. The PMC-592 provides Dip/Swell detection on a per phase basis and can

trigger the following parameters at the same time: WFR, SOE and Alarm Setpoints. The timestamp,

duration and Maximum and Minimum of three phase voltage of each Dip/Swell would be recorded by

PMC-592.

For applications that require 12-CT Strips, it is not recommended to assign SM from 1 to 48 (with 4x12-

CT Strips). Instead, use the default SM assignment as if the 21-CT Strips were used and leave gaps in the

SMs. The data from the un-used SMs would all be 0. In addition, it is strongly recommended to install

all 12-CT Strips using the Top Installation Direction; otherwise, there will be an invalid 2-Ø SM for each

CT Strip as shown below:
