5.3.5 DEMAND METERING
PATH: ACTUAL VALUES ÖØ A2 METERING DATA ÖØ DEMAND METERING
The values for current and power demand are shown here. This peak demand information can be cleared using the S1 489
SETUP ÖØ CLEAR DATA ÖØ CLEAR PEAK DEMAND setpoint. Demand is shown only for positive real and positive reactive
power (+Watts, +vars). Peak demand will not update if a digital input programmed as Test Input is shorted.
5.3.6 ANALOG INPUTS
PATH: ACTUAL VALUES ÖØ A2 METERING DATA ÖØ ANALOG INPUTS
The values for analog inputs are shown here. The name of the input and the units will reflect those programmed for each
input. If no analog inputs are programmed in the
S11 ANALOG I/O setpoints page, the THIS FEATURE NOT PROGRAMMED
flash message will appear when an attempt is made to enter this group of messages.
5.3.7 SPEED
PATH: ACTUAL VALUES ÖØ A2 METERING DATA ÖØ SPEED
If the Tachometer function is assigned to one of the digital inputs, its speed be viewed here. A bar graph on the second line
of this message represents speed from 0 RPM to rated speed. If no digital input is configured for tachometer, the
THIS FEA-
TURE NOT PROGRAMMED flash message will appear when an attempt is made to enter this group of messages.
