4 COMMISSIONING

4.1 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.
•
Please refer to Chapter 3 "INSTALLATION
" for details.

4.2 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.

4.3 Checking system functions

The GD10P is factory calibrated, and does not require any adjustments before operation. A
check prior to putting into service should however consist of:
1) Clean the optical surfaces
The detector may have been collecting dirt after being initially installed. It is thus crucial to
clean the optical parts before testing the detector (refer to Paragraph 6.1 "Cleaning of optical
lens/mirror").
