Pfeiffer Vacuum ASM 310 - Connecting the exhaust; Electrical connection; Connecting the part;installation to be tested

●
relative excess pressure: 200 hPa
●
flow rate: 5 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 neutral gas purge connector (see chapter “Connection
interface”).
5.3 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).
The detector exhaust filter (EXHAUST) must never be removed.
The detector exhaust (EXHAUST) must never be obstructed.
5.4 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.
NOTICE
Risk of electromagnetic disturbance
Voltages and currents can induce a multitude of electromagnetic fields and interference signals. In-
stallations that do not comply with the EMC regulations can interfere with other equipment and the
environment in general.
►
Use shielded cables and connections for the interfaces in interference-prone environments.
Electrical safety
The leak detector is Class 1 equipment and therefore must be earthed.
►
Connect the power supply to the connector using the power cable supplied with the detector (see
chapter “Connection interface”).
►
See chapter “Technical characteristics”.
5.5 Connecting the part/installation to be tested
NOTICE
Risk of deterioration of parts or installations
There is a risk of deterioration for parts or installations connected to the leak detector vacuum circuit.
►
Make sure that the parts or installations connected to the detector’s pump inlet withstand a nega-
tive pressure of 1 · 10
3
hPa in relation to the atmospheric pressure.
