Gas sampling and gas conditioning technology 2-1.1.7.6-ME
13.3 CONNECTION OF DILUTION GAS OR BYPASS GAS
For connection of the supply lines, tube connectors with dimension 6 x 1mm are available. mm zur
Verfügung. The connection fittings of the heated dilution units are located outside the cover and can
be connected without disassembly. Only when using the heat
ed versions and option I, a heated “undi-
luted” sample line is connected to the bypass outlet. Please act as follows:

Remove protective cover

Open the fastening clamp

Mount the hose pipe or tube to the respective fitting

Shut the fastening clamp again

Install the protective cover again.
When using option
–A (only dilution gas) or –A1 (dilution and bypass gas), the supply lines are con-
nected to the connection fittings of the precision pressure regulator.
When using the 19“ control panels –S or –S1, corresponding connectors for the supply gases are pro-
vided at the rear of the unit.
13.4 CONNECTION OF CALIBRATION GAS
For all versions of DIL-1 and DIL-1/H, a tube connector 6 x 1 mm is available for connection of the
calibration gas (see figure 4).
13.5 ELECTRICAL CONNECTION
The temperature setting on the dilution unit DIL-1/H is made on the internal capillary thermostate.
W A R N I N G !
The incorrect mains voltage can destroy the unit. Check the type
plate for the correct voltage prior to connection!
The dilution units must be mounted in such a way that touching the
live parts is excluded!
In any case, we recommend the use of temperature resistant ca-
bles!
The alarm contact for low temperature must be controlled!
In case of a low temperature alarm (failure of heating or sensor) the
dilution gas or bypass gas supply must be interrupted to avoid se-
rious damage of the dilution unit. We recommend to switch the low
temperature alarm onto external solenoid valves that provide the
above mentioned function!
