7.3 Air flow sensor adjustment
Air flow initialising for the TITANUS MICRO·SENS
®
is completed suc-
cessfully if a stable status for temperature and air flow is set for a pe-
riod of 2 minutes. The maximum duration is 2 hours.
Air flow initialising for the TITANUS MICRO·SENS
®
is completed
successfully if for a period of 2 minutes the following status is set:
- the temperature oscillates by less than 0.1K and
- the air flow does not oscillate too much (temperature regulation) and
- the ventilator voltage can be set properly
- ventilator and ventilator power supply working normally
The maximum duration is 2 hours.
Air flow initialising is interrupted immediately if any of the following errors
occur:
- Temperature measurement defective
- Air flow measurement defective
- Ventilator control defective
Types of adjustment
z Adjustment can be conducted independently of the current air pres-
sure. The restrictions for this kind of adjustment can be found in Chap-
ter 4.3 "Air Flow Monitoring".
z The air flow sensor can be adjusted as a function of the current air
pressure.
In order to be able to assess the air flow sensor figure correctly during
maintenance work, record the type of adjustment in each case in the test
records.
7.3.1 Air Pressure-Independent Adjustment
Air pressure-independent adjustment for the TITANUS MICRO·SENS
®
happens completely automatically each time the detection unit is inserted
into the device base and the Jumper X4 is changed or via the diagnosis
tool.
During the learning phase, the alarm detection is fully functional. During
this time the operating display flashes and there must be no air flow
influences. When initialising is completed, the operating display changes
to a permanent light and the air flow sensor has determined its ideal
value for the connected pipe system.
