Test certificates are included in the equipment documentation.
4 Settings
4.1 Air quantity
The flow should be set according to the sensor type:
 Transmitter with electrochemical sensor ~60 l/h
 Transmitter with electrochemical IR transmitter
in series ~80 l/h
 IR transmitter ~180 l/h
The flow should be matched to the circumstances in the system
as a whole.
4.2 Standard system without delivery unit
The sample air leaves the process with excess pressure!
 The sample gas flow should be set to 60 l/h at the fine
regulating valve on the flow meter. The top of the ball is the
read mark for the scale.
 Notice on handling: see the Instructions for Use for the
flow meter.
4.3 System with ejector unit
 To function correctly, the regulating valve needs an input
pressure of 1 bar to 10 bar. The control range of the
regulating valve is 0.2 bar to 10 bar.
 Setting the sample gas flow:
 Open the fine regulating valve on the flow meter (turn anti-
clockwise to the stop, then 1 turn back).
 Set the flow approximately at the regulating valve, then carry
out the fine regulation using the regulating valve on the
flow meter. The top of the ball is the read mark for the scale.
 Notice on handling: see the Instructions for Use for the
flow meter and for the regulating valve.
4.4 System with gas sampling pump
 The sample gas flow should be set to 60 l/h at the fine
regulating valve on the flow meter. The top of the ball is the
read mark for the scale.
 Setting the sample gas flow:
 Open the fine regulating valve on the flow meter (turn anti-
clockwise to the stop, then 1 turn back), set the flow
approximately at the bypass valve on the gas sampling
pump, then carry out the fine regulation using the
regulating valve on the flow meter. The top of the ball is the
read mark for the scale.
 Notice on handling: see the Instructions for Use for the
flow meter and for the gas sampling pump.
4.5 Circuit breaker (option)
 The circuit breaker is delivered together with the aspirator
system as a separate item. Installation is carried out on site
by the operator in accordance with the assembly
instructions. Information is included in the documentation.
 The circuit breaker makes it possible to monitor line breaks
and short circuits. Furthermore, the action of the relay can
be reversed by means of a switch. Settings should be
adjusted in accordance with the operator's requirements
during commissioning. Information is included in
the documentation.
 Standard: Auxiliary power 24 V DC
 Optional: Auxiliary power 230 V, 50 Hz
