The Human Machine Interface

The IED 670 products can be ordered with a small or medium HMI module.

Both have a LED panel and a serial communication port on the front panel. The

Parameter Setting Tool in PCM 600 toolbox installed on a PC is used to set

parameters via the serial port. The PC cable to the HMI from the PC shall be a

crossed Ethernet cable with RJ45 connectors. If it is connected via a hub a stan-

dard Ethernet cable is used. The Medium HMI has a 150x180 mm Graphic dis-

play where single line presentation and control of the IED can be shown in

addition to the setting information.

The following keys are provided to navigate the menus:

•

C is used to cancel or clear

•

E is used to confirm or enter

•

L/R is used to set local or remote control

•

Menu alternates between the menu screen and graphic mode

•

Reset activates the reset screen

•

Help activates the help screen

I closes a disconnector or breaker

•

O opens a disconnector or breaker

•

The arrow keys are used to navigate between different screens and data

To change a setting, select an item in the menu structure and change it using the

up and down keys on the HMI. After selecting parameter values move up

through the menu system by repeatedly pushing the left arrow key until a dialog

box appears where changes can be confirmed or cancelled.

The LEDs on the front panel of the IED are configured with the Signal Matrix

Tool and are activated by various events, such as Distance protection trip, Phase

selection L1, L2 and L3 and Auto Reclose. The LEDs are labelled according to

the configuration chosen. The label is printed and inserted manually from the

top, see picture. The labels for each LED can include a maximum of 18 charac-

ters in Arial 16 font. These 15 LEDs are alarm indicators and are colored red

(1-6) and yellow (7-15). When active they will show flashing or steady light.

Use the Reset button to reset the LEDs. Above the LCD there is a green

(depends on settings), a yellow (start) and a red (trip) LED. These are activated

by general start and trip operations. The Trip logic function block (TRM) must

be used and set ON to activate the red LED.
