1.8 Risk / Potential hazard
KIMESSA gas detection systems and transmitters pose no risks subject to a proper and appropriate. use of our
systems and components, these represent no hazard. A threat of non-execution or false alarm is only given
when untrained and unauthorized personnel operate the gas detection system, transmitters and input signals.
The responsibility for this, or for the omission of regular maintenance work and the consequences are borne by
the owner of the gas warning system, even if a maintenance contract is in place and service personnel have no
access to the system.
1.9 Safety / Responsibility
The safety function is guaranteed if the gas detection systems, transmitters and other system components are
regularly inspected i.e. once or twice a year by authorized and qualified personnel having obtained training by
the KIMESSA staff for a specific product. The responsibility for compliance with rules and regulations rests with
the owner or his representative, including for regular testing of the system as part of cyclical maintenance.
1.10 If Ex-measuring sensors are connected in hazardous areas the following must
be observed:
Safety information for hazardous areas
•Pay attention to the applicable
-Regulations and specifications (ExVO, BetrSichV, etc.)
-Requirements for testing of personnel ("qualified" person, TRBS 1203)
•Installation, commissioning and periodic inspection must be carried out by suitably qualified personnel
("authorized persons")
•Compliance with important data for explosion protection must be met through the labelling of the pro-
duct
-G= Gas, D=Dust
-Equipment category 1,2,3 in the 3 zone areas
-Characteristics of the gas: Temperature class (T1..T6), explosion group (IIA, B, C)
-Dust characteristics: Explosion group (III A, B: non-conductive; IIIC: high conductivity); surface tempe-
rature, smoulder and ignition temperature
If the so called ex-gas sensors are connected it should be noted that the sensor is suitable for
use in gas and dust explosion hazard areas (zone 2 and 22).
The applicable regulations for installation, operation and maintenance of gas detection systems
for monitoring of combustible gases and oxygen, for example
(EN / IEC 60079-29-2) and for monitoring of toxic gases such as (EN 45544-4)
must be observed and complied with.

•The deposit of dust is to be avoided so that the surface temperature does not dangerously increase. (in-
stallation position, protection, cleaning measures, etc.)
•Care must be taken to ensure that all technical and organizational precautions are met and their func-
tion or effects are tested.
•If an "X" is present after the EC-Type Examination Certificate number, there are special stipulations or
deviations from the standard conditions. In this case, these special instructions can be found in the certi-
ficate.
•Before any work (installation etc.) is performed in potentially explosive atmospheres, a work permit
must be submitted by the operator.
If Ex-measuring sensors are connected in hazardous areas the following must be observed:
For work such as installation, electrical connection, repair or opening of the housing, it must be
ensured that
•no explosive atmosphere is present
•no electric voltage is applied
•accidental activation is not possible
•there is a work permit from the operator
Changes to the equipment are not allowed and can lead to triggering an
explosion (ignition)!
Additional information on use in potentially explosive dust atmospheres:
•The details of the maximum surface temperature are valid only for a dust allowance of more than 5
mm. At higher dust allowance the surface temperature must
be reduced
•Determining the maximum permissible surface temperature
-Dust with ignition temperature-TCL: Tmax1= 2/3 TCL
-Dust layer with ignition temperature-T5mm: Tmax2= T5mm – 75oC
-The smaller of the two values is decisive for the maximum
permissible surface temperature
• During installation and operation of the equipment, it must be ensured that no electrostatic
charges (no high flow rate; cleaning with a damp cloth, etc.) occur on the plastic parts (type
label, plastic housing).

2Usage
2.1 Introduction

The universal KIMESSA CANline 02 gas monitor has been designed to ensure safety of persons. The KIMESSA
CANline 02 gas detection control unit is a compact, economic evaluation unit, which is available in different
versions and can handle up to 2 measurement channels.
In addition the 2 analogue/BUS sensors, several touch displays, relay cards and further modules can be
connected to the CANline 02 control unit. Aside from the 5 internal potential-free relays, there are up to 128
further potential-free, programmable relay contacts, which are provided with 3 alarm thresholds per measuring
point and can be split into 2 fire/ventilation zones or groups. The CANline 02 control unit also has an alarm for
over- and undershooting the measurement signal, with which relevant relays can be programmed that then, for
example, visualize a fault accordingly.
Pressing the SELECT button shows the values of individual sensors. The RESET button is used to reset the system
when limits are exceeded. The control unit has a history function that documents and displays limit exceedances
and errors from the connected sensors precisely to the second. The parameters of the sensor and the entire
system can be programmed with the integrated USB interface.
In conjunction with the KIMESSA BUS sensors, there are many cost-saving cabling possibilities, which also include
connecting in KIMESSA BUS signals so that only one cable has to be run. Other features include the ability to
record over long periods of time using a MicroSD memory card.
The CANline 02 gas detection control unit comes in a panel-mount version as well as in the standard wall-
mounting housing, each with an integrated power supply.

4Installation
4.1 Conditions of use/Installation/Where and how will the control unit be
mounted?
The control unit housing is neither water-proof nor explosion-proof The monitor should be placed in a dry and
non-hazardous area. It can be installed directly onto the wall or into a cabinet.
The ambient temperature for the operation of the CANline 02 gas detection control unit should be between -
10 °C to 40 °C. The relative humidity must be between 5% RH (relative humidity) and 95% RH. Ideally, the unit
is installed vertically on the wall or in a cabinet (plastic/metal). For installation in the control cabinet, for examp-
le on a DIN rail, two nuts are inserted (metal piece with threading) and secured directly into the rail. For installa-
tion onto the control cabinet door, there is a mounting frame. The cable glands are mounted on the lower part
of the CANline 02 housing, facing downwards. It is important to ensure that the gas detection control unit is
always accessible. Note that the upper part of housing opens upwards for wiring, programming and during
maintenance work. It may be necessary to secure the gas detection control unit in exposed locations with a
mechanical bumper buffer device/ram protection. When cleaning in its vicinity, do not expose the control unit
to any contamination and avoid splashing water and vapours.

If ex-sensors are used, refer to the following for ex-sensor installation:
Before the unit (ex-sensor) is installed, the following checks must be carried out
•The device must not show any damage or other conspicuous changes
•The IP protection of the device must conform to the operational and environmental conditions
•The operator must have already defined zones
•Check whether the device category corresponds to the predefined zones
•Check the product documentation, whether any upstream safety devices (fuse, etc.) are required
•Specification of ex-technical requirements, safety characteristics of the potentially explosive substances,
zone areas, ambient temperatures
The following standards and rules are helpful
•BGR-104: Explosion protection regulations
•EN 1127-1: Explosion protection basics and methodology

Observing the primary task of supervision at gas detectors:
•Direction of propagation of the gases
Upwards, if the gas is lighter than air (natural gas, hydrogen, etc.)
Downwards, if the gas is heavier than air (almost all gases)
•Areas in which gases appear:
In the vicinity above or below a potential leakage point
•Areas in which gases accumulate:
In the upper and lower spaces of a room
•Health protection with regard to toxic gases and oxygen:
Position, mouth height approx. 1.6m
Additional information on use in potentially explosive dust atmospheres:
•The deposit of dust is to be avoided so that the surface temperature does not dangerously increase.
(installation position, protection, cleaning measures, etc.)
•During installation and operation of the equipment, it must be ensured that no electrostatic charges (no
high flow rate; cleaning with a damp cloth, etc.) occur on the plastic parts (type label, plastic housing).

4.2 Mechanical installation of CANline 02
Unpack the gas detection control unit and check for missing parts or transport damage. Also check the technical
specifications. Compare the nameplate with the actual product that you ordered. Be especially careful if additi-
onal assembly aids are present, such as mounting plates or installation frames.
Open/close the gas detection control unit, remove it from/install it via the back panel by screwing
in/unscrewing the housing screws (M3 flat screwdriver or M3 Phillips head screwdriver).
Install the control unit directly on the wall or in the control cabinet on DIN rails or on/in the control cabinet door.
After installation, attach the upper part again (plastic brackets). Close the control unit and check the fit: If the
back panel is properly installed, the control unit closes easily.

When working on the gas detection system, use your personal protective
equipment, safety boots, helmet, goggles, hand-held measuring instrument, respira-
tory protection and, if necessary, hearing protection and gloves.

should be added to the total power.
4.9 Sensor-Cable BUS-Installation
Recommended: 4-Core control cable, shielded
Cable diameters/Distances
Data transmission is guaranteed up to approx. 1000 m. The power consumption of each node must be added
together.
In each case, the cable cross section must be calculated. The length of the + wire and the −wire and the total
power consumption must be taken into consideration
When working on the gas detection system, use your personal protective
equipment, safety boots, helmet, goggles, hand-held measuring instrument, respira-
tory protection and, if necessary, hearing protection and gloves.
Please note the regulations concerning the transport and storage of gas bottles.

KIMESSA –Electronic cable, shielded
1506.2 ZK CAVO LIHCH 4x1.00 (30x0.200) DIN 47100 - GIALLO 1021 ∅7.10-40°C / +70°C –
These shielded cables for flexible
application, free-moving without
tensile load or forced movements,
are suited for installation in dry en-
vironments and may not be used
outside of buildings. LIHH cable for
electronic, computer, measurement and control systems can be used wherever cables with small external diame-
ters are required. The insulation and sheath are made of a special plastic (LSZH) which prevents halogen gases
from being emitted in the case of a fire. KIMESSA electronics cables are therefore suitable for installation in
public buildings (hospitals, theaters, etc. ). The good protection by the shield of a thin and effective copper braid
allows for interference-free signal and impulse transfer. The use of KIMESSA electronics cable is recommended
especially for safety-critical systems in public facilities and plants with high reliability requirements.

e.g., total cable length approx. 750 m/cable cross section 0.75 mm2

During tightening the gland, hold the cable

Risk of electrical shock!
Electrical operations should only be performed by qualified electrician personnel.
Before opening the unit, disconnect power and secure against inadvertently restarting
the power.
When in a potentially explosive area, make sure:
•to check whether the device category corresponds to the predefined zones
•no explosive atmosphere is present
•there is a work permit from the operator
•to comply with applicable rules
•to ensure that the documentation of the devices used in operations such
as installation, electrical connection, repair or opening of the housing is complete
•no electric voltage is applied
•accidental activation is not possible
The transmitter supply line must be shielded or the supply line must be laid in metallic cable routing. If an
unshielded supply line is used, it must be ensured that no other current-carrying line is run along the same
conduit, see Transmitter Datasheet. The supply line must be X-wired (see Transmitter Datasheet) and is limited by
the terminal port in the transmitter to 1.0 mm2.
•Selecting connection cable
When selecting the cable, the following points should be noted:
-Select cable material with regard to the local
resistance requirements
-?-wired standard cable with shield
-Conductor cross-section: 1 mm2
-Cable diameter 7.1 mm, KIMESSA special cable
•Running cable
-If risk of mechanical damage is possible, the cable must be appropriately protected (protective tube,
etc.)
-The cable diameter must be complied with so that the
connection in the cable entry point remains tight
-The gland and the screws of the housing cover must be tightened so that IP protection is maintained.
Excessive pulling damages the seal and thus affects the IP protection
•Grounding system
-The external grounding terminal on the housing must be connected
to the potential equalizer of the hazardous area with low resistance
-No potential equalization currents may flow between hazardous areas and non-hazardous areas.
-Minimum cross-section: 2 x 1.5 mm2 or 1 x 4 mm2
-Ground connection of the electrostatic charge with a resistance between 0.2-1 MOhm does not qualify
as grounding

Electrical connection of sensors and explosion sensors
- Make sure that the lines to be connected are not energized. Otherwise,
there is a risk of damage to the unit and of igniting an explosive atmos-
phere!
Before the device is supplied with voltage, the following inspections (TRBS 1201) must be carried out:
•Inspection of order:
-if the equipment used complies with all safety-related parameters (device category, surface tempe-
rature.)
-if the documentation is complete and comprehensive
(permits, regulations, certificates, checks to be carried out, etc.)
•Technical inspection
-Screws, for a tightness of
connection, protective and potential equalizer terminals
housing cover
-Torque of the cable entry point
-Tightness between cable and seal in the cable entry point
-Check whether the device is ready for operation
The parameterization for this application must be carried out
All interfaces such as inputs and outputs for control purposes must be connected and ready.
