…7 Operation
Figure 21 shows an overview of Operator pages 2 to 3. Each
Operator Page displays the PV and temperature from a single
sensor. Fixed, color-coded, user-assignable tags (one for each
fitted sensor) and color-coded bargraphs aid identification of
each sensor.
The bargraph indicates the PV. Minimum and maximum PVs are
configurable in the Sensor Setup level. If the measured PV is
above the maximum specified range of the sensor (refer to the
sensor’s Operating Instruction), the bargraph flashes to
indicate the value is outside the specified range.
When multiple sensors are fitted and Autoscroll is selected
from the Operator Menu (see page 20), the display scrolls
through each available Operator Page consecutively.
