Technical Overview LED Indication
The GS-S-CO-LED has 6 LED indicator lights which change
colour based upon concentration levels. This allows for easy
visual awareness of the CO levels, with either a relay or
RS485 interface output.
Installation
1. Select a location on a wall of the controlled space which
will give a representative sample of the prevailing room
condition.
Avoid sitting the sensor in direct sunlight, near
diffusers and steam sources.
2. Gently remove the front cover from the back plate. The
front plate is removed by pressing the tab at the top of
the sensor with a flat bladed screwdriver. Gently slant
the screwdriver and this will separate the front cover
from the back plate.
3. Using the base as a template mark the hole centres and
fix to the wall with suitable screws. Alternatively the
base plate can be mounted on to a conduit box or a
standard recessed back box.
4. Feed cable through the knockout in the base of the
housing and terminate the cores at the terminal block.
Install wiring into terminal blocks as required, and push
excess wire back into wall or junction box.
5. Select the relay switching point using jumpers J1 & J2.
6. Ensure that the supply voltage is within the specified
tolerances.
7. Replace the front cover to the base plate until a click is
heard.
8. Power the unit, pre-commissioning checks can be made
after 10 minutes. Full commissioning should not be
carried out for at least 36 hours.
9. It is recommended that screened cable be used and that
the screen should be earthed at the controller only. Care
should be taken not to lay control signal wiring in close
proximity to power or other cables which may produce
significant electromagnetic noise.
