LEDs
min 8
The LHMI includes three protection indicators above the display: Ready, Start and
Trip.
There are also 11 matrix programmable LEDs on front of the LHMI. The LEDs
can be configured with PCM600 and the operation mode can be selected with the
LHMI, WHMI or PCM600.

REF615
The LHMI keypad contains push-buttons which are used to navigate in different
views or menus. With the push-buttons you can give open or close commands to
objects in the primary circuit, for example, a circuit breaker, a contactor or a disconnector. The push-buttons are also used to acknowledge alarms, reset
indications, provide help and switch between local and remote control mode

Audit trail
615 series IEDs offer a large set of event logging functions. Normal process related
events can be viewed by the normal user with Event Viewer in PCM600. Critical
system and IED security related events are logged to a separate non-volatile audit
trail for the administrator.
Audit trail is a chronological record of system activities that enable the
reconstruction and examination of the sequence of events and/or changes in an
event. Past user and process events can be examined and analyzed in a consistent
method with the help of Event List and Event Viewer in PCM600. The IED stores
2048 system events to non-volatile audit trail. Additionally, 1024 process events
are stored in non-volatile event list. Both audit trail and event list work according
to the FIFO principle.
User audit trail is defined according to the selected set of requirements from IEEE
1686. The logging is based on predefined usernames or user categories. The user
audit trail events are supported in IEC 61850-8-1, PCM600, LHMI and WHMI.
