Selection Description

Default

 

 

 

 

CT Primary

1–32,767

Set the rating for the CT primary. The circuit monitor supports two primary CT

5

 

 

ratings: one for the phase CTs and the other for the neutral CT.

 

 

 

 

 

CT Secondary

1 or 5

Set the rating for the CT secondaries.

5

 

 

 

 

PT Pri Scale

x1

Set the value to which the PT Primary is to be scaled if the PT Primary is larger

x1

 

x10

than 32,767. For example, setting the scale to x10 multiplies the PT Primary

 

 

x100

number by 10.

 

 

No PT

For a direct-current installation, select “No PT.”

 

 

 

 

 

PT Primary

1–32,767

Set the rating for the PT primary.

120

 

 

 

 

PT Secondary

100

Set the rating for the PT secondaries.

Sys Type

3Ø3W2CT

3Ø3W2CT is system type 30

3Ø4W3CT (40)

 

3Ø3W3CT

3Ø3W3CT is system type 31

 

 

3Ø4W3CT

3Ø4W3CT is system type 40

 

 

3Ø4W4CT

3Ø4W4CT is system type 41

 

 

3Ø4W3CT2PT

3Ø4W3CT2PT is system type 42

 

 

3Ø4W4CT2PT

3Ø4W4CT2PT is system type 43

 

 

 

Set the system type. A system type code is assigned to each type of system

 

 

 

connection. See Table 5–2 on page 38 of the installation manual for a description

 

 

 

of system connection types.

 

 

 

 

 

Frequency (Hz)

50, 60, or 400 Hz

Frequency of the system.

60

 

 

 

 

Pwr Dmd Meth

Select the power demand calculation method. The circuit monitor supports several methods to calculate

Slide

 

average demand of real power. See “Demand Power Calculation Methods” on page 57 for a detailed

 

 

description.

 

 

 

Slide—Sliding Block Demand

 

 

Slave—Slave Block Demand

 

 

Therm—Thermal Demand

 

 

RComms—Command-Synchronized Rolling Block Demand

 

 

Comms—Command-Synchronized Block Demand

 

 

RInput—Input-Synchronized Rolling Block Demand

 

 

Input—Input-Synchronized Block Demand

 

 

RClock—Clock-Synchronized Rolling Block Demand

 

 

Clock—Clock-Synchronized Block Demand

 

 

RBlock—Rolling Block Demand

 

 

Block—Fixed Block Demand

 

 

IncEngy—Synch to Incremental Energy Interval

 

 

 

 

 

Pwr Dmd Int

1–60

Power demand interval—set the time in minutes in which the circuit monitor

15

 

 

calculates the demand.

 

 

 

 

 

Pwr Dmd Sub Interval

1–60

Power demand subinterval—period of time within the demand interval in which the

N/A

 

 

demand calculation is updated. Set the subinterval only for methods that will

 

 

 

accept a subinterval. The subinterval must be evenly divisible into the interval.
