11 - Performance table
General notes:
• The performance values given in the next table are valid with ≥ 100 ms trip time, temperature
and signals within the operating limits; failure to comply with these limitations could lead to an
increase in the tolerances.
• Ekip Touch sends the TRIP command if the signal read exceeds the threshold for longer than the
set time (or the time resulting from the calculation formula)
• with an inverse time-delay trip curve, the calculation refers to a signal with a constant value
throughout the timing: variation of the alarm signal causes a different trip time
• The additional notes are given after all the tables
