Connect gas and power lines:
Do not install the sensor until the gas lines have been connected and the electrical connections made.
Install the unit, and connect the sample gas lines, power and appropriate alarm and output connections. Connect the
sample gas line to the fitting on the rear panel using the ¼” compression fittings provided, and the exhaust line to a
suitable vent.
Sample gas:
The sample gas inlet pressure should be between 1-40psig.
Span gas:
Span gas (if desired) must be provided by a user-supplied valve.
Exhaust:
The exhaust line may be left open, or vented to a suitable vent. If used with a scavenging system, use a large diameter
pipe (for example, ½” pipe) as the input to the scavenging system, and allow the ¼” vent to terminate a little way
inside this larger line without sealing it. The scavenging system will then draw in room air along with the sample,
while leaving the exhaust at atmospheric pressure.
Power connections:
The 201LC is designed to be operated from a 24V power supply only. Use a suitable wall adapter, or other kind of
stable DC power supply. Make sure the ground is connected to a real ground – otherwise you may experience
