3 User Interface

Operation, parameter selection, and control of the ISGS relay

are performed using the front panel controls and indicators.

They consist of a 26-key membrane keypad, a 2-line by

16-character liquid crystal display (LCD), three light-emitting

diodes (LEDs), and the front port.

3.1 Keypad

The relay can be controlled via the keypad, the front port, or

the optional rear port. This manual covers only keypad oper-

ations. For information about communicating with the ISGS

relay via the data ports, refer to the documentation supplied

with the communications software (WinPM or Wisdom).

The ISGS relay keypad allows access to any relay informa-

tion or function for display or parameter changes where

applicable. The keypad consists of 26 keys. Table 3.1 pro-

vides a detailed description of each key type.

To access relay information or functions for display or modifi-

cation, use the Arrow keys to scroll through relay addresses

or use the Direct Addr key and the specific address number

to go directly to the information or function.

Use the Double Arrow keys to scroll through the address

blocks and use the Single Arrow keys to scroll within an

address block.

3.2 Indicators

The indicators on the front panel display consist of three

LEDs and a two-line LCD.

3.2.1

LEDs

The LED indicators are used to provide general status infor-

mation, which alerts the operator to an event or problem and

prompts the operator to use the LCD to review the logs for

more detailed information. The three LEDs and their func-

tions are listed below.

Both the Pickup and the System LED operate automatically

and do not require a reset.

The System LED remains on as long as power is applied

and the relay is functioning properly.

The Pickup LED is illuminated as long as a protective

function is in pickup.
