●
relative excess pressure: 200 hPa
●
flow rate: 50 sccm (if pressure = 1 bar (absolute) at the inlet)
Use pressure
If the neutral gas pressure is too high, the inlet vent valve may remain closed.
●
0 to 0.3 bar relative (≈ 0 to 4.5 psig)
●
1 to 1.3 bar absolute (≈ 14.5 to 19 psig)
Procedure
►
Connect the neutral gas pipework to the inlet vent and purge connector (see chapter “Connection
interface”).
5.5 Connecting the exhaust
NOTICE
Risk of deterioration due to overpressure at exhaust
Too much pressure at the detector’s exhaust risks damaging the detector.
►
Ensure that the customer application exhaust line is always under slightly negative pressure.
►
Make sure the detector’s exhaust pressure does not exceed 200 hPa (relative).
Dry model
The detector's exhaust is equipped with an external filter.
The detector exhaust filter (EXHAUST) must never be removed.
The detector exhaust (EXHAUST) must never be obstructed.
►
Clean the filter regularly.
Wet model
NOTICE
High-pressure pumping - Wet model only
►
Connect the exhaust of the detector to an exhaust duct or pipe.
Connection: 1/8 gas
The detector's primary pump is equipped with an internal oil mist eliminator.
The detector exhaust (EXHAUST) must never be obstructed.
The operator can connect an external eliminator instead of this internal eliminator.
►
Install the connection tubing designed for this purpose and available as an accessory (see chapter
“Connecting an external oil mist separator”).
If degassing the customer application, you are advised to connect the detector exhaust to an exhaust
line (at the customer’s charge), ensuring that the detector is always used in compliance with the recom-
mendations given.
5.6 Electrical connection
WARNING
Risk of electric shock due to non-compliant electrical installations
This product uses mains voltage for its electrical supply. Non-compliant electrical installations or in-
stallations not done to professional standards may endanger the user’s life.
►
Only qualified technicians trained in the relevant electrical safety and EMC regulations are au-
thorized to work on the electrical installation.
►
This product must not be modified or converted arbitrarily.
