6.10.3.2.3 Alarm settings – Delay
The delays are used to suppress the alarm that has been triggered in situations where the threshold is
briefly exceeded or undershot.
The delay can be entered in seconds or in hours - minutes - seconds. To enter the colon, please use
the "dot" key. After confirming the data using the Enter key, the input value is displayed in the format
[Hours]: [Minutes]: [Seconds].
Example: CO alarm is set as follows:
If the threshold is exceeded, the following sequence of events occurs:
