Setup of Monitor Limits, a survey of adjustments.
Limits Adjustments
Voltage 2 Probability percentages (100 % and adjustable):
each with adjustable upper and lower limit.
Harmonics For each harmonic 2 Probability percentages (100
% and adjustable): each with adjustable upper limit.
Flicker 2 Probability percentages (100 % and adjustable):
adjustable percentage with adjustable upper limit.
Weighing curve (lamp type): adjustable under
FUNCTION PREFerence, Flicker, Lamp Model.
Dips (*) Reference voltage (Nominal or Sliding as selected
under Function Preference/Dips & Swells).
Threshold, hysteresis, allowed number of
dips/week.
Swells (*) Reference voltage (Nominal or Sliding as selected
under Function Preference/Dips & Swells).
Threshold, hysteresis, allowed number of
swells/week.
Interruptions (*) Threshold, hysteresis, allowed number of
interruptions/week. Reference voltage is Nominal.
Rapid Voltage Changes (*) Allowed number of events/week. Voltage tolerance:
adjustable under FUNCTION PREFerence, F3 –
RAPID CHANGE
Unbalance For each harmonic 2 Probability percentages (100
% and adjustable): adjustable percentage with
adjustable upper limit.
Frequency 2 Probability percentages (100 % and adjustable):
each with adjustable upper and lower limit.
Mains Signaling 2 Adjustable frequencies. For each frequency 2
probability percentages (100 % and adjustable):
adjustable upper limits (**).
(*): setups that are also valid for measuring mode Dips & Swells. Events per week is used for Monitor only.
(**): when changing frequency, limits automatically follow the EN50160 ‘Meisterkurve’, but can also be set
manually. The ‘Meisterkurve’ is shown in the figure below.
