Each wellness status can be set ON or OFF. If activated, the status is measured as a ratio of
the actual value against the calculated value obtained from settings of lower limit and upper
limit. For limit setting see Appendix 4. The status is indicated as a number in between 0
(bad) and 4 (good).
6.4.6 Sensor status
The SA11 monitors some process conditions of the connected sensor:
•
Maximum temperature exposed
, which is automatically updated every time a higher
process temperature is measured.
•
High temperature 1/High temperature 2
, which is the total time at which the sensor
is exposed above the corresponding limits, set by the Yokogawa HOST system. The last
date and time (the end of high-temperature condition) is stored.
•
Sterilization
, which reflects the number of times at which the temperature remains
above the preset value for at least the prescribed time period set by the Yokogawa HOST
system.
Figure 6.2: Example of sterilization
a. This event is not counted because the duration does not reach the prescribed sterilization
time.
b. This event is counted because the duration exceeds the prescribed sterilization time.
c. This event is counted because the duration exceeds the prescribed sterilization time.
However long the event lasts, it is counted as one.
The number of counts is up to 9999. The date and time of the last count is stored even
when the maximum number of counts is reached.
6.5 Output setup
The SA11 Smart Adapter is normally always in operation mode. Only a dedicated HOST
(FLXA402 expert HOST) can set the SA11 in three other modes:
•
Sleep
, all operations which result in output data will be disabled. Communication however
is still active.
•
HOLD
, calculated output data will be set in a fixed value:
o Last value
o Maximum limit (hardcoded limits of SA11 which can be overruled by expert HOST)
o Minimum limit (hardcoded limits of SA11 which can be overruled by expert HOST)
o Not a number (no result of calculated output data)
When SA11 is in HOLD only the output data is ‘frozen’, all other operations are still active.
•
Safely remove
, wherby it is safe to remove the SA11 without the risk of losing data.
6.6 Calibration and Commissioning
Allows the user to calibrate and configure the SA11 device. For details see section 7 and
section 8.
