Description of temperature maximum logging function:
The temperature value is supervised constantly. As soon as the value exceeds the actual maximum value, the
time measurement starts. The minutes are added up, the period can be requested by the user any time. The
actual maximum value is overwritten by a higher value automatically, if it lasts more than 30 seconds; the time
measurement starts once more. The determined values (max temperature/period) can be cleared by the user.
They are written into the parameter Old durat/value after Clear values or after power off/on, the actual time
value is deleted, the max temperature value is set on the actual temperature value. By switching Temp max
log off the values are not cleared.
When exceeding the maximum temperature of 70°C the error message “Temp over limit” appears.
