2.1
Installing the Monitor
The rear panel has a serial-link and a USB socket for the PC
interface. The mains input, sample gas inlet and outlet for expelled
gas samples are located on the rear panel.
2.1.1 Operating Environment
The following environmental conditions must be observed:
•
Safe ambient operating temperatures range from 5°C to 40°C
•
Humidity should not exceed 90% RH non-condensing.
Warning! The monitor is not intended for use in explosive
environments.
2.1.2 The Gas Sample Line
The gas to be sampled (measured) is drawn from the sample point
via a sample line at a flow rate of 800 ml/min. Various types of
sample lines are available depending on the individual application.
The sample line tubing between the sample point and the monitor
should be kept as short as possible to assist response times. If you
are unsure about the type of sample line for your application, contact
your LumaSense representative for advice before installing the
system.
Up to 100 m tube (AF0614) with internal diameter 3mm can be
attached. The response time is then 70 sec.
Note: You must use a filter in the gas-line immediately before the
gas-line enters the monitor. The UD 5091A in-line filter (optional
accessory) is ideal for this purpose.
The gas inlet for the sample line is located on the rear panel of the
monitor. If the dew point of the gas sample is comparable to the
temperature in the monitor, Nafion tubing UD5037 can be used to
remove water and eliminate the risk of condensation inside the
monitor
Nafion is impermeable to O

whereas alcohols and other gases will completely or partly penetrate
through the material. Contact an LumaSense Technical Support
representative for advice on whether or not to use Nafion when
monitoring a particular gas.
You should protect the Nafion tubing against the effects of ultra-
violet light, as this reduces the tubes lifetime. Nafion tubing should
