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 26), the display scrolls
through each available
Operator Page
consecutively.
