How to acknowledge and reset targets, output contacts and
memorized values
• To clear the LEDs and the display, press
. The LEDs and the display will be
cleared only if the fault has disappeared.
• Press
for at least five seconds to unlatch the output contacts. Note that the
LEDs and the display have to be cleared before this.
• Press
and
simultaneously for at least half a second to perform a master
reset, i.e. to clear targets and memorized values and to unlatch the output
contacts. The display being inverted confirms this action. Memorized values
include recorded data, disturbance recorder data and average values (demand
values).

Protection relay targets
The operation of the relay can be monitored by means of three different kinds of
targets on the HMI:
• Three target LEDs with fixed functionality: Ready, Pickup/Alarm and Trip
• Eight programmable target LEDs
• A text message on the display
The protection functions are not affected by fault targets.
