CARBON-DIOXIDE TRANSMITTER
TRANSMITTER

Overvie
The PHG transmitter measures CO2 concentration in in-door atmospheres and
converts it into standard current or voltage signal. PHG model uses dual N IR
carbon-dioxide sensor for better accuracy and sensitivity as well as low temperature
and humidity dependence. The transmitter can be equipped with local 4-digit LE
display and RS232 serial interface. PHG application area includes indoor air control,
ventilation, air-conditioning, mushroom control, etc.
Mounting
Free mounting
♦ Remove 2 protection plastic caps (1)
using a flat-screwdriver tip.
♦ Fix the unit using 4 M4 screws with
proper length through holes (2) to your
mounting construction or use the
supplied COMECO mounting
accessories.
♦ Return the protection caps to their
original places.
Duct mounting
♦ Place the supplied flange to duct wall
and mark 2~4 mounting holes.
♦ rill on duct wall d4.5mm flange holes
and a d17mm central hole.
♦ Fix the flange (3) using 2~4 M4 screws
(4) with proper length.
♦ Place the transmitter inlet tube to the
desired process depth and front rotation.
Fix it with flange fixing screw (5).
Important notes:
♦ Do not try to open the enclosure.
It can damage the transmitter!
♦ Sintered filter significantly increases
the response time!
Wiring
♦ Check the pin numbers of the male
connector located on housing top or
bottom.
♦ Turn off power supply!
♦ Attach the female connector part wired
to your system as shown on the left.
♦ Turn the power supply on.
♦ If RS232 interface is installed:
- Baud Rate: 9600 bps
- Transmit Update: 2 s
- Transmit Frame:
