5. Safety
This manual contains general instructions that must
be observed during installation, operation and
maintenance. This manual must therefore be read by
the installation engineer and the relevant qualified
personnel/operators prior to installation and start-up
and must be available at the installation location of
the Conex
®
DIA-G at all times.
It is not only the general safety instructions
described in this section 5. Safety that must be
observed, but all special safety instructions that are
provided in the other sections.
5.1 Risks when safety instructions are not
observed
If safety instructions are not observed, it may result
in personal injury or damage to the Conex
®
DIA-G. If
safety instructions are not observed, this may lead to
the loss of any claims for damages.
If individual safety instructions are not observed, this
may cause for example the following damage:
failure of specified methods for recording gas
concentrations and secondary safety equipment
harm to humans from exposure to electrical,
mechanical and chemical influences.
5.2 Obligations of the owner/operations
manager
The owner/operations manager must ensure that
persons working with the described device fulfil
these requirements:
They are acquainted with the regulations
concerning working safety and accident
prevention.
They have been trained in use of the device.
They have read and understood the warning
information and handling symbols.
The owner/operations manager is also responsible
for ensuring that this manual is kept in the immediate
vicinity of the device and is always available for the
operating personnel and that the local safety
regulations are observed when setting the limit
values for the sensors.
5.3 Avoidance of danger
5.3.1 Safety instructions for the operator
Damage caused by electrical energy must be
prevented. For more details, see for example the
regulations of the VDE, German Association for
Electrical, Electronic and Information Technologies,
and the local power supply company.
5.3.2 Safety instructions for maintenance,
inspection and installation work
The operator is responsible for ensuring that all
maintenance, inspection and installation work is
carried out by authorised and qualified personnel,
who have been adequately trained by reading the
installation and operating instructions.
All safety and protective equipment must be
immediately restarted or put into operation once
work is complete.
Observe the points described in the initial start-up
section prior to subsequent start-up.
Warning
Do not use the device for monitoring
constant concentrations. The device is
designed for detecting leaks.
Warning
Installation and connection of the device
and the associated supplementary
components must only be carried out by
qualified specialists!
The local safety regulations must be
observed!
Warning
Switch off the power supply before
connecting the power supply cable and
relay contacts!
Do not dismantle the device! Maintenance
and repairs must only be carried out by
authorised specialists!
Caution
The mounting location must be selected so
that the housing is not subjected to
mechanical loading.
Check that all settings are correct before
starting up the device!

7.1 General description
The Conex
®
DIA-G is a gas warning controller for
monitoring gas concentrations, for example in
storage or dosing rooms. With a maximum of two
independently connected sensors, the gas
concentration of chlorine, ozone, chlorine dioxide,
hydrochloric acid or ammonia can be displayed and
monitored. Amperometric sensors (sensor discs) can
be connected directly to the Conex
®
DIA-G, and
potentiostatic sensors can be connected to a
preceding Conex
®
DIA-G sensor interface.
Each of the two sensors is provided with electrically
isolated current outputs (potential-free to power
supply) to output the measured concentration, two
electrically isolated limit value transmitters and an
alarm relay to control the warning and safety
equipment.
The Conex
®
DIA-G meets the high safety
requirements through permanent sensor monitoring,
alarm relays and optional backup mode (connection
of an external backup battery for supplying power to
the Conex
®
DIA-G in case of short-term power
supply interruptions).
How the system operates
The gas sensors generate a current which is
proportional to the gas concentration in the air.
The Conex
®
DIA-G gas warning controller
– amplifies the sensor current
– triggers an initial warning, for example when
the first limit value is exceeded
– activates the relevant warning and safety
equipment when the second limit value is
exceeded
– outputs the measured concentration at both
sensors as a 0 (4) - 20 mA signal via the
current outputs (for example for recording).
