5.3.5 DEMAND METERING
The values for current and power demand are shown here. This peak demand information can be cleared using the
S1 489
SETUP \ CLEAR DATA \ 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
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
If the Tachometer function is assigned to one of the digital inputs, the tachometer readout may 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 in the
S3 DIGITAL INPUTS
setpoints page, the
THIS FEATURE NOT PRO-
GRAMMED
flash message will appear when an attempt is made to enter this group of messages.
