Possible events:
Failure supply voltage
Setpoint status change
Relay actions
Digital input status changes
Setup changes
Each event record includes the event classification, the relevant parameter values
and a timestamp in 1 ms resolution.
All event entries can be retrieved via the communications interface.
The event log can be cleared using the buttons on the front panel or via communi-
cations interface.
7.7 Power Quality
7.7.1 Harmonic distortion
The device provides an analysis
Total Harmonic Distortion (THD)
Even Total Harmonic Distortion (TEHD)
Odd Total Harmonic Distortion (TOHD)
k-factor
All harmonics up to the 31
st
order
The evaluation of the harmonic components is carried out when a current of at
least 150 mA (current input 1 A) resp. 750 mA (current input 5 A) flows.
All parameters are available on the display or the communications interface.
The following parameters are provided:
L1
L2
