5 Commissioning
5.1 Visual inspection
Make certain that all the operations of the “Installation” chapter have been achieved correctly.
Pay particular attention on installation conformity, check the cables entry, the presence of O-
rings, and the connection of the cartridge.
•
The label on the smart sensor indicates the type of detector, the type of gas and the range
for which the instrument has been calibrated
•
The cartridge colour must correspond to the type of detector:
-
Yellow for combustible gas
-
Brown for catharometer
5.2 Power-up
The detector is powered through the multichannel detection unit or the Programmable Logic
Controller.
•
The backlight turns violet
•
The display (red) appears. It displays, among other information, the INH which indicates
the start-up inhibition and the warming up remaining time in
min and sec.
•
After this warming up time, the backlight turns green and the current concentration is
displayed.
5.3 Operational tests
All MultiXplo / MultiTox detectors are delivered set and tested. Some additional tests are
necessary to check the good working of the loop. Please make sure to have all authorizations
needed before running the following operations:
•
Check the states/information using the TLU600 or TLH700 (hart) or the magnetic wand,
•
Check the alarm levels
•
Zero point: If there are no polluting gases or, if necessary, by injecting clean air at 30 l/h
using the calibration kit equipped with an air cylinder
•
Sensitivity: By injecting a suitable gas mixture at 30 l/h using the calibration kit
•
Check the servo controls
