Data Entry Principles

Follow these steps to modify parameter or protection settings using the Sepam™

UMI:

1 Enter the proper password for either the protection or the parameter settings

(see "Entering Passwords", page 82).

2 Display the screen with the value you want to modify (see "Displaying operating

Information", page 83).

3 Modify the values using one of the three entry methods offered, depending on

the type of parameter or protection settings:

b entering Boolean values

b selecting a value from a number of options

b entering numerical values

4 Final confirmation of all the new parameter or protection settings for use by

Sepam™.

Entering Boolean Values

The Sepam™ display shows Boolean parameters and protection settings as two

buttons, representing the two status conditions of Boolean data. For example, the

language used for the operating texts on the Sepam™ UMI is a Boolean parameter

that can have one of two states:

b UK English

b US English as the local language

Use the following process to modify the value of a Boolean parameter or protection

setting:

1 Position the cursor by pressing or as needed.

2 Confirm the selection by pressing .

Selecting Values From a List of Options

Certain parameters and protection settings must be selected from a list of

possibilities. For example, the type of tripping curve for the "phase overcurrent"

protection function is selected from among 16 predefined curves (such as, DT, SIT,

VIT, EIT, etc.).

Perform the following steps to select a particular parameter or protection setting:

1 Press or as needed to position the cursor on the value you want to

modify.

2 Press to confirm your value selection.

3 Press or to scroll through the possibilities.

4 Press to confirm the new value.

Entering Numerical Values

The Sepam™ display shows numerical parameters and protection settings as three

digits, with or without the decimal point and the unit symbol.

To modify the value of a numerical parameter or protection setting, follow these

steps:

1 Press or as needed to position the cursor on the value you want to

modify.

2 Press to position the cursor on the first digit.

3 Use or as needed to scroll through the character list. The available

characters are the digits from 0 to 9, the decimal point, and a space.

4 Press again to confirm your choice and proceed to the next digit. After

confirming the third digit, the cursor positions on the unit symbol.

5 Use or as needed to scroll through the available units.

6 Press to confirm unit selection.
