1. General In truction
1.1 Indication
This manual has to be read carefully before switching on the instrument.
The instructions must be strictly adhered to.
Non-ob ervance of the e in truction may lead to the lo of right to
claim for damage or warranty!
Meaning of signs used in this instruction manual:
: Warning
: Indication of particular importance
: Avoid actions marked with this sign
CATCHWORDS appear in italics on the right hand margin

1.2 Safety Precaution and Important In truction
The 2240 PROcheck-Analyzer is designed for monitoring, displaying,
and logging the levels of a certain compound (gas).
The analyzer is not intended to be a safety monitor. The 2240
PROcheck-analyzer is not designed for use in potentially e plosive
environments. Never place and operate the instrument in areas with a
potentially e plosive atmosphere!
The analyzer should be used only for its intended field of application and
should be operated only by qualified personnel.
1.3 Tran portation / Storage / Unpacking
During transportation please make sure that the instrument is being pro-
tected against violent shocks or impacts. Transportation of instrument
should as a matter of principle only be made in original cardboard bo
containing shock absorbing elements. When storing the instrument for a
longer period of time, it should be wrapped in a plastic hood together
with a silica gel bag for protection against humidity. During storage or
transportation e posure of the instrument to temperatures below -10° or
higher than +60° C must be avoided.
TRANS-
PORTATION
DAMAGES?
Immediately after unpacking the instrument should be visually inspected
for e ternal damage which might have been caused to it during transpor-
tation. In the event of such damage, the supplier has to be informed im-
mediately and the instrument must not be switched on by any means.

2.2 De cription of function
2.2.1 De cription of en or function
In Gas Monitors 2240 PROcheck a sensor is being used which
operates on the principle of
Infrared - NDIR.
By means of which the physical quality of many gases to react to
electromagnetic waves (for instance infrared rays) is being e ploited
as they respond to a single (or to several) wave length(s) specific to
every kind of gas as well as absorb such energy.
PRINCIPLE
An infrared radiation source emits IR-radiation of a wide range and of
different wave lengths. An optical filter permits the passage of defined
wave lengths of small band width from the radiation source's
spectrum. This defined bandwidth is characteristic for the gas
component to be determined.
At this wave length the gas component will absorb IR-radiation. This
effect is converted into electric signals by a measuring transducer.
The concentration of the gas component is being calculated via
calibration functions filed in the Gas Monitor's configuration library.

2.2.2 De cription of equipment function
The devices of the type 2240 PROcheck are primarily intended for
measurement of gas concentrations in fumigation processes. They are
equipped with 3 measuring gas connections, which can be selected
either by the instrument software automatically or by an e ternal
controller (Plant- or machine-control). Two limits per channel can be
adjusted to suit your requirements independently.
For measuring the gas concentration of the currently selected
measurement channel, the gas to be analysed is drawn by the device
internal diaphragm pump through a particulate filter and the sample
gas line in the sensor (active sampling). During the measuring
operation a large number of individual measured values is integrated.
The result is continuously displayed and compared with the limiting
values valid for the current measurement channel.
A comparison of the set limits versus measured value will be e ecuted
only after a predetermined time (set by device software) to avoid
mispricing by short-term fluctuations in concentration. The formation
of mean values for the storage (USB / GSM) begins just after this time
has elapsed.
The “traffic light” indicator on the front panel visually inform about
the status of the measuring channel with respect to the set limits.
For the behavior of the alarm contacts are three settings available:
NO (normally open)
NC (normally closed)
Alarm window
The following tables describe the status of the LED lights and the
signal contacts with different alarm settings.
