Program step 1 should be always a definite initial state, here atmospheric pressure. To reach this state
definitely set a tickmark at venting and ”Step” (press selection knob).
Step 2 causes pumping down to 10 mbar within 5 minutes (linear ramp) as ”Step” is not set.
Step 3 keeps the vacuum (10 mbar) constant for 15 minutes.
Step 4 vents within 1 minute to 500 mbar.
Step 5 keeps 500 mbar for 9 minutes.
Step 6 pumps down to 5 mbar within 10 minutes.
Step 7 keeps the vacuum (5 mbar) constant for 20 minutes.
Step 8 vents as fast as possible to atmospheric pressure and switches off the control after one minute.
Vacuum pump with isolation valve and/or Vacuum-Management-System Module A: Pumping
