QUICK REFERENCE GUIDE
OVERVIEW OF THE GM10 MODULE
INSTALLATION
GM10 is the carbon dioxide measurement module utilized in the
GMW90 and GMW80 series of wall mount transmitters.
Replacing the module restores the CO2 measurement accuracy of
the transmitter.

User calibration settings (if provided by your transmitter model)
are stored in the GM10 module. When you replace the module,
you do not need to undo the previously applied correction.

CAUTION
Handle the GM10 module carefully.
CAUTION
Electrostatic Discharge (ESD) can cause
immediate or latent damage to electronic
circuits. To avoid damaging the modules or
the transmitter, avoid touching any
component contacts or connectors.
Remove the locking screw(s) from the transmitter if they
are installed.
Use a flat screwdriver to push down the tab that holds the
transmitter cover and mounting base together, and pull
the top of the transmitter cover away from the mounting
base.
CAUTION
Do not insert tools into the housing. Be
careful not to damage any components when
pushing on the tab.
For best protection, handle the transmitters
and modules on a properly grounded and
protected ESD workbench.

3.
Locate the GM10 module on the transmitter. The module
is a separate component board with a golden cuvette that
contains the CARBOCAP® sensor. It is connected to the
main transmitter board with a connector, and held in
place by a plastic clip on the other side.
Note the orientation of the module. The new module must
be installed in the same way.

Disconnect the module by carefully lifting the module
from the connector side. Lift straight up to avoid bending
the pins or damaging the connector.
5.
GMW90 only: A short piece of foam pipe is included
with the GM10 spare part. Place it on top of the
calibration gas inlet inside the transmitter, as shown in
the figure below. If the foam pipe is already in place and
appears undamaged, you do not have to replace it.

9.
Lower the connector end of the module, and push down
on the module to secure the connector. The module
should now be straight and firmly connected.
Reconnect the transmitter to the mounting base.
Verify that the transmitter starts up and the CO2
measurement functions normally.
