Instructions in brief for Installation, Commissioning and Operation
Analyzer data sheet
Fidas24:
Mains lead, length 5 m, with 4-pin socket connector and separate
grounding connector for the power supply to the heating of the
detector and the heated sample gas connection
Accessories pack with fittings and O-rings for connection of the
sample gas line
Exhaust pipe with fitting nut and compression fitting
Material Required for the Installation (not supplied)
Gas Connections
For the connection of pipelines: Threaded connections with a 1/8 NPT
thread and PTFE sealing tape
Fidas24: Use only metal threaded connectors!
Fidas24: Gas lines
Process gases, test gases and waste air
PTFE or stainless steel tubes with 4 mm inside diameter and
PTFE or stainless steel tube with at least 10 mm inside diameter for
waste air
Tube fittings
Pressure regulator
Flow restrictor in the combustion gas supply line (see page 30)
Shut-off valve in the combustion gas supply line (see page 30)
Sample gas
Heated sample gas line (recommended: TBL 01) or
unheated sample gas line (PTFE or stainless steel tube with
inside/outside diameter 4/6 mm).
The fittings and O-rings required for the connection are included in
the scope of supply and delivery of the gas analyzer.
Flowmeter/Flow Monitor
Flowmeter or flow monitor with a needle valve for adjustment and
monitoring of the sample gas flow rate and purge gas flow rate if
required
Notes for the selection and use of flowmeters:
Measuring range 7…70 l/h
Pressure drop < 4 hPa
Needle valve open
Recommendation: Flowmeter 7…70 l/h, Part Number 23151-5-
8018474
Shut-off Valve
Install a shut-off valve in the sample gas line (definitely recommended
with pressurized sample gas).
Purging of the gas line system
Provide a means for purging the gas line system by feeding in an
inert gas, e.g. nitrogen, from the gas sampling point.
Installation Material
19-inch Case (Model EL3020)
4 oval head screws (Recommendation: M6; this depends on the
cabinet/rack system)
1 pair of mounting rails (Design depends on the cabinet/rack system),
length approx. 240 mm corresponding to approx. 2/3 of the case
depth
Wall-mounting Case (Model EL3040)
4 screws M8 or M10
Signal Lines
Select conductive material which is appropriate for the length of the
lines and the predictable current load.
Notes concerning the cable cross-section for connection of the
I/O modules:
The max. capacity of terminals for stranded wire and solid wire is
1 mm2
(17 AWG).
The stranded wire can be tinned on the tip or twisted to simplify
the assembly.
When using wire end ferrules, the total cross-section may not be
more than 1 mm2
, i.e. the cross-section of the stranded wire may
not be more than 0.5 mm2
. The PZ 6/5 crimping tool of
Weidmüller & Co. must be used for crimping the ferrules.
Max. length of the RS485 leads 1200 m (max. transmission rate
19200 bit/s). Cable type: 3-core twisted-pair cable, cable crosssection 0.25 mm2
(e.g. Thomas & Betts, Type LiYCY).
Max. length of the RS232 leads 15 m.
Power Supply Lines
If the supplied mains lead is not used, select conductive material
which is appropriate for the length of the lines and the predictable
current load.
Provide a mains isolator or a switched socket-outlet, in order to be
able to disconnect all the power from the gas analyzer if required.
Requirements for the Installation Site, Power Supply
NOTE
For the analyzers ZO23 and Fidas24 the information contained in the
sections "ZO23: Preparation for Installation" (see page 25) or "Fidas24:
Preparation for Installation (see page 30)" must be considered in addition.
Requirements for the Installation Site
The gas analyzer is only intended for installation indoors.
The max. altitude of the installation site may not exceed 2000 m above
sea level.
The installation site must be stable enough to bear the weight of the gas
analyzer!
To ensure safe installation and removal, we recommend that the 19-inch
housing is supported in a cabinet or rack with slide rails!
Short gas paths
Install the gas analyzer as close as possible to the sampling location.
Install the gas conditioning and calibration modules as close as possible
to the gas analyzer.
Adequate air circulation
Provide for adequate natural air circulation around the gas analyzer.
Avoid heat build-up.
Mount (see page 66) several 19-inch housings with a minimum spacing of
