Operational check
The operational check can be effected with or without a digital manometer.
In the following the complete check is described. If during the operational
check of TITANUS
®
the values vary from those given in the following the de-
vice or its air flow sensor is damaged.
1. Make sure the device has been operating for at least 30 minutes.
2. Close all air sampling points of the test pipe by means of adhesive tape.
After a short initiation period the depression generated in the device is to
be approx. 250 up to 310 Pa for a set fan voltage of 6.9 V and 460 up to
530 Pa for 9 V.
3. Free the air sampling point at the test pipe again. After about 120 secs
press the Init-button S2 on the detector module. The LED in operation
flashes and the fault LED must go out (see INSTRUCTION).
4. Close the air sampling points of the test pipe with adhesive tape. After
several seconds of “blockage”, the flash code of the LED on the detector
module must flash.
5. Re-open all air sampling points of the test pipe. After a few seconds the
flash code of the LED must go out.
6. Remove the test pipe. The LED flash code on the detector module I and
detector module II must signal “fracture” for several seconds.
7. Re-connect the test pipe to the device. After a few seconds the LED
flash code must go out.
NOTICE
A pipe fracture or blockage is indicated by a flash code via the LEDs on the
detector module I and module II detector:
- fracture: 3x flashing
- blockage: 2x flashing
The corresponding flash code is repeated every two seconds.
NOTICE
For a TITANUS
®
with 2 pipe systems, the preparation for functional testing
with the steps 1 - 7 to perform for both pipe systems.
