The LHMI presents pages in two categories: the Operator

pages and the Engineer pages. The Operator pages include the

ones which are typically required as a part of an operator’s

normal activities, such as a single-line diagram, controls,

measurements, events, alarms, and so on. The Engineer’s

pages include specifically designed pages supporting relay

parametrization, troubleshooting, testing and commissioning

activities.

The Operator pages can be used as such or customized

according to the project’s requirements using Graphical Display

Editor (GDE) within the PCM600 software tool. The Engineer

pages are fixed and cannot be customized.

The Operator pages can be scrolled either by tapping the Home

button or by swiping the actual pages. The Engineer pages are

accessible by touching the upper horizontal section of the

screen.

The LHMI is an accessory for the relay which is fully operational

even without the LHMI. The relay communication card has a

dedicated port where the LHMI is connected using an RJ-45

connector and a CAT6 S/FTP cable. The LHMI can be

connected to the relay also via station communication network

if a longer distance is required between the relay and the LHMI.

Additionally, the LHMI contains one Ethernet service port with

an RJ-45 connector and one USB port. The service port can be

used for the PCM600 connection or for Web HMI connection.

Data transfer to a USB memory is enabled via the USB port. By

default the USB port is disabled and has to be taken into use

with a specific parameter.
