Demand values are the calculated average values of measured parameters over a user defined period.
Average values are compared to the demand values at the end of the period, and if the new value is
greater, it is recorded as the demand value. Demand values are automatically reset at the start of each
month. Thus, demand values are valid only for the current month.
Demand calculations can be done for the following values:
- demand I1
- demand I2
- demand I3
- demand Io (average current)
- demand active power
- demand reactive power
Min-max values are dependent on internal measurements. They may be sensitive to short term changes
and transients since they do not have an averaging period, such as starting currents due to engine starts.
As long as the unit is active, it compares the actual value to the recorded minimum or maximum value. If
the actual value provides the condition (greater than max or less than min), it is recorded as the new
value.
Pressing the
and
buttons together for 5 seconds resets the min-max values.
Min-max values can also be reset from the programming menu. relevant parameter:
ELECTRICAL PARAMETERS > Reset Min/Max
For more robust results, min/max detection starts 10 seconds after the device powers on. Mains demand,
minimum and maximum values are located in the
Mains Electrical Parameters
display group.
Navigating between screens is done by using the
buttons.
Min/max is calculated for the following values:
- Mains Min voltage L1-N
- Mains Min voltage L2-N
- Mains Min voltage L3-N
- Mains Min voltage L1-2
- Mains Min voltage L2-3
- Mains Min voltage L3-1
- Mains Min frequency
- Mains Min current I1
- Mains Min current I2
- Mains Min current I3
- Mains Min current Io (average current)
- Mains Min active power
- Mains Min inductive reactive power
- Mains Min capacitive reactive power
- Mains Max voltage L1-N
- Mains Max voltage L2-N
- Mains Max voltage L3-N
- Mains Max voltage L1-2
- Mains Max voltage L2-3
- Mains Max voltage L3-1
- Mains Max frequency
- Mains Max current I1
- Mains Max current I2
- Mains Max current I3
- Mains Max current Io (average current)
- Mains Max active power
- Mains Max inductive reactive power
- Mains Max capacitive reactive power
