5.1 Visual inspection
The following should be checked before initial powering up:
•
The axis of the detector shall be horizontal,
•
Correct cable gland installation,
•
Electrical connection,
•
Electrical grounding,
•
Termination of cable shield,
•
Orientation of the weather protection,
•
All bolts and screws are tight.
Check the presence and good condition of the O-ring (no cracks, cuts, good elasticity) on the
back cover. Make sure that the flat support surface is clean, properly greased and that it does
not show any visible scratches or "knocks".
Please refer to Chapter 4 "Installation" for details.
5.2 Power up
Ensure that system wiring and control system are in working order before powering the detector.
The startup period takes about 60 seconds, a functional self-test is performed during this time.
When the self-test is completed the detector turns over to measuring mode. The 4-20mA output
will stay at 0mA during the 60 seconds startup period and 4mA (if no gas is present) in measuring
mode. The graph on the left shows the reading of the 4-20mA analog output during startup
period.
