3.2.3.4. How to acknowledge and reset indications, output contacts and
memorized values
• To clear the LEDs and the display, press the [C] button. The LEDs and the
display will be cleared only if the fault situation has disappeared.
• Press the [C] button for at least five seconds to unlatch the output contacts. Note
that the LEDs and the display have to be cleared before this.
• Press the [C] and [E] buttons simultaneously for at least half a second to perform
a master reset, i.e. to clear indications 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.
