5.10 Extreme Environment Status
5.10.1 Description
With the help of the
Extreme Environment Status
, the time
is recorded in which the device was exposed to extreme
conditions. In parameter
Lifetime Extreme Thresholds
, limit
values can be configured for the respective conditions.
Parameter
Lifetime Extreme Status
can be used to read
out the current status as well as the summed time. The
calculation is based on the features of temperature (see
chapter 5.11 on page 68), humidity (see chapter 5.14
on page 76) and vibration (see chapter 5.13 on
5.10.2 Mathematics/Algorithm
If one (or more) extreme conditions are met, the device
begins to record the time.
If the power supply is interrupted during this time,
the time counter can have an error of maximum
180 seconds.
