      Control power rating on the CM4000 series meter is different than what is stated in the specifications in CM4 manual

      Issue
      Control power rating is different than what is shown in the CM4000 series user manual 

      Product Line
      CM4000 Series

      Environment
      Wiring

      Resolution
      The control power for the CM4000 series Circuit Monitors is rated for a voltage range of 90-305V ac or 100-300V dc. It was our standard practice to publish these ratings. Recently a change was implemented to mark the circuit monitors with the nominal voltage ranges instead of the maximum range. As a result the meters now show a control power voltage range of 100-277 V ac or 125-250 V dc.

      What values should be set for the potential transformer (PT) primary and secondary values in a CM4000 when connecting the voltage inputs of meters directly to the bus (with fuses)?

      Issue
      A user may want to know the PT primary and secondary values for a CM4000 upon initial setup

      Product Line
      CM4000

      Environment
      Setup

      Cause
      The meter may be set to "No PT" or the PT ratio may be used. 

      Resolution
      When setting the PT ratio, one may select "No PT" for the PT Primary Scale - there is no requirement to set the PT ratio if "NO PT" is chosen.

      The PT Primary and PT Secondary inputs are still available, but they are not used when "No PT" is selected for the PT Pri Scale.
      A user would set the PT ratio to "No PT" when the system voltage used by the load to be metered is the same as the system voltage connected directly to the meter (i.e. direct connect with no potential transformers used).

      The PT ratio needs to be set only when the load is using a different voltage from the meter voltage inputs (i.e. potential transformers are being utilized). Potential transformers are used when the voltage of the electrical system is higher than the rated specifications of the meter voltage inputs. The PT primary and secondary ratio on the meter should match that of the potential transformers in the field.

      Example 1: When metering a 1.2 kV system with a set of PT's that contain a ratio of 1200:120, the PT Primary of the meter should be set to 1200 and the PT Secondary of the meter should be set to 120.
      (Potential transformers are used in this scenario because 1.2 kV exceeds the acceptable voltage input threshold the CM4000 can withstand (1–690 L-L, 400 L-N)

      Example 2: When metering a a 480V L-L system, no PT's are being used. The system voltage is directly connected to the metering inputs. In this scenario, you would set the PT Pri Scale of the meter to "No PT".

      Note: If the meter receives voltage that is the same as the voltage used by the load and "No PT" is NOT selected, then a PT ratio of 1:1 would need to be used and is still acceptable. (i.e.This result can be achieved by setting the PT Ratio to 120:120 or 480:480)

      How to calculate Energy readings from the raw Integer register data on an Energy Meter

      Issue
      The energy values are stored across two 16-bit integer registers on an energy meter. 

      Product Line
      Energy Meter

      Environment
      Reading and converting Modbus register values

      Resolution
      The Energy Meter stores energy across two 16-bit integer registers.

      Register #1 and Register #2 (Modbus address 257/258 for Register #1 and 259/260 for Register #2). Register #2 is the High WORD and Register #1 is the Low WORD. 

      The Multiplier/Divisor table states that both of these registers must be divided by 32 to obtain the real value from the raw data.
      The Multiplier/Divisor should NOT be applied to both registers. It is applied to the final value of both registers.

      To calculate the Energy the registers must first be arranged as the register list states [2] is the High word and [1] is the Low word.

      To make [2] the High word it needs to be shifted to the left 16 bits.
      To accomplish this multiply the value in [2] by 65,356.
      You will then add this value to the value in [1].
      The final value will be divided or multiplied by the correct scaling value. Please see the example listed below.

      For this example we will assume an Energy Meter with 300 amp CTs. According to the Integer Multiplier/ Divisor table, 300 amp CTs will give a divisor value, (d), of 32 and a multiplier value, (m), of 0.03125.
      We will assume the following register values.
      Register #1 = 29,586
      Register #2 = 31

      Using Divisor Table
      kWh = ([R2]*65,536+[R1])/d
      kWh = (31*65,536+29,586) / 32
      kWh = 64412.56

      Using Multiplier Table
      kWh = ([R2]*65,536+[R1]) * m
      kWh = (31*65,536+29,586) * 0.03125
      kWh = 64412.56

      *Note the divisor will not always be 32 and the multiplier will not always be 0.03125. For the correct values please see the Integer Multiplier Table.
