11-6-8 Temperature Range Count
Description
Counting starts when this
temperature is exceeded.
When the temperature range is
set to 10°C above the set
temperature (95°C), the function
counts how long the temperature
is within that 10°C range.

This function times (in 1-second units) how long the temperature input value is
within a user-set temperature range. The range count (zone count) can indi-
cate when preventative maintenance is required for devices or applications
that deteriorate at a fixed rate within the user-set temperature range.
Select the temperature range settings on the Comparator Tab Page. The
temperature range boundaries are defined by the High High Limit (HH), High
Limit (H), Low Low Limit (LL), or Low Limit (L). If the time within the set tem-
perature range exceeds the monitor value, it indicates that a threshold value
has been exceeded. The status can be read in the Monitor Window or via an
explicit message to know when a threshold has been exceeded.
The Over Threshold status can be read in the Maintenance Information Win-
dow or via an explicit message.
