Provides information about instrument properties and properties of the equipment associated with the instrument.

Supply

Select the type of supply that the instrument requires: alternating current (AC) or direct current (DC).

Number of phases

Select the number of phases for the instrument. You can select 1 or 3 phases. This property applies for an AC supply only.

Frequency (Hz)

Select the operating frequency of the instrument. You can define and customize the available frequencies in the Data Dictionary Manager. This property applies for an AC output only.

Instrument rated power

Allows you to enter the power requirement for the instrument.

Power factor

Enter the ratio of active power to apparent power at 100% of the rated power and at the demand point for the associated equipment. The power factor can have a value between 0 and 1.

Rated voltage

Select the voltage at which the instrument is designed to operate. This quantity usually appears on the instrument nameplate. You can define and customize the available rated voltages in the Data Dictionary Manager.

Rated active power

Shows the quantity of electrical power in kW drawn from the network and supplied to the associated equipment that is actually converted to output power.

Rated reactive power

Shows the quantity of reactive power in kVAR that the associated equipment draws from the network.

Rated apparent power

Shows the quantity of electrical power in kVA that represents the vector sum of the active and reactive power. This quantity is the actual power that the network needs to generate for the associated equipment.

Override FLA calculation

Select the required option to determine whether the software uses a calculated or manually typed full load current value. If you select Calculated, the software calculates the full load current value based on values you enter on this tab; the calculated value overwrites any value that you previously entered manually. Selecting Manual enables data entry in the Full load current box, with the last calculated full load current as the starting value.

Full load current (FLA)

The electrical current, in amperes, that the instrument measures for the associated equipment when operating at maximum power. You can select Calculated or Manual from the Override FLA calculation list to determine whether the software calculates this value or whether you enter a value manually. When the associated equipment has an attached cable, the software copies this value to the cable and uses it as a default value for sizing the cable.

Starting current

The electrical current, in amperes, that the instrument measures for the associated equipment when starting. When the instrument has an attached cable, the software copies this value to the cable and uses it as a default value for sizing the cable.

Coincidence factors

Allows you to enter values corresponding to the percentage utilization of the associated equipment for the selected operating mode. Also known as duty factors. Type a value between 0 and 1 for the required mode. A value of 0 corresponds to an unused load, while a value of 1 corresponds to continuous operation.

Operating mode

Select the operating mode that describes how the associated equipment is used in practice in the plant. The standard available operating modes are:

Continuous

Intermittent

Standby

Spare

The coincidence factor corresponding to the selected operating mode provides a quantitative measure of the associated equipment behavior in that mode. You can customize the available operating modes in the Data Dictionary Manager.

Manage Operating Cases

Opens the Manage Operating Cases dialog where you can add, edit, or delete property values specific to various plant operating cases that exist for the current plant item.
