Overview MIQ/CR3; DIQ/CR3

1.2 Features of the combi output module
General
characteristics
The combi output module has three current outputs and three relay outputs. You
can link current outputs and relay outputs to sensors. The linked current outputs
and relay outputs can, for example, be used to monitor sensors or to output
measurement data. Unlinked relay outputs can be used for general monitoring
functions.
With the standard MIQ module housing, the combi output module has the same
characteristics as all MIQ modules regarding stability, leakproofness and
weather resistance. It also provides the same wide variety of installation options
(stacked mounting, canopy mounting, tophat rail mounting, etc.).
Instrument types The MIQ/CR3 and DIQ/CR3 combi output modules differ in their compatibility
with the individual IQ SENSOR NET system families.
Terminal strip The combi output module has the following electrical connections on the
terminal strip inside the housing:
3 x relay contact
3 x current output
2 x SENSORNET connection

2 Safety instructions
2.1 Safety information
2.1.1 Safety information in the operating manual
This operating manual provides important information on the safe operation of
the product. Read this operating manual thoroughly and make yourself familiar
with the product before putting it into operation or working with it. The operating
manual must be kept in the vicinity of the product so you can always find the
information you need.
Important safety instructions are highlighted in this operating manual. They are
indicated by the warning symbol (triangle) in the left column. The signal word
(e.g. "CAUTION") indicates the level of danger:
NOTE
indicates a situation where goods might be damaged if the actions mentioned
are not taken.
2.1.2 Safety signs on the product
Note all labels, information signs and safety symbols on the product. A warning
symbol (triangle) without text refers to safety information in this operating
manual.
2.1.3 Further documents providing safety information
The following documents provide additional information, which you should ob-
serve for your safety when working with the measuring system:
Operating manuals of other components of the IQ SENSOR NET system
(power supply modules, accessories)
Safety datasheets of calibration and maintenance equipment (e.g. cleaning
solutions).
WARNING
indicates a possibly dangerous situation that can lead to
serious (irreversible) injury or death if the safety instruc-
tion is not followed.
CAUTION
indicates a possibly dangerous situation that can lead to
slight (reversible) injury if the safety instruction is not fol-
lowed.

Safety instructions MIQ/CR3; DIQ/CR3

2.2 Safe operation
2.2.1 Authorized use
The authorized use of the MIQ/CR3; DIQ/CR3 consists of providing relay and
current outputs in the IQ SENSOR NET. Only the operation according to the
instructions and technical specifications given in this operating manual is autho-
rized (see chapter 6 TECHNICAL DATA). Any other use is considered unautho-
rized.
2.2.2 Requirements for safe operation
Note the following points for safe operation:
The product may only be operated according to the authorized use specified
above.
The product may only be operated under the environmental conditions men-
tioned in this operating manual.
The product may only be supplied with power by the energy sources men-
tioned in this operating manual.
The product may only be opened if this is explicitly described in this operating
manual (example: connecting electrical lines to the terminal strip).
2.2.3 Unauthorized use
The product must not be put into operation if:
it is visibly damaged (e.g. after being transported)
it was stored under adverse conditions for a lengthy period of time (storing
conditions, see chapter 6 TECHNICAL DATA).
2.3 User qualification
Target group The IQ SENSOR NET system was developed for online analysis. Some mainte-
nance activities, e.g. changing the membrane caps in D.O. sensors, require the
safe handling of chemicals. Thus, we assume that the maintenance personnel
is familiar with the necessary precautions to take when dealing with chemicals
as a result of their professional training and experience.
Special user
qualifications
The following installation activities may only be performed by a qualified electri-
cian:
Connection of the MIQ/CR3; DIQ/CR3 to the power supply.
Connection of external, line voltage-carrying circuits to relay contacts (see
module manual of the relay output module).
