Test Procedure Positive Test Pressure
• A positive pressure is built up with the FPE pump.
• The pump is stopped and the valves closed if the set-point pressure for PDA
= +400 mmHg is reached.
• The PDA reference value is stored after a wait state of 5 s.
• This reference value is compared with the actual value after 30 s.
• If the deviation is < 10 mmHg the next test step is performed.
Test Step 1 VLA, VEBK1/2, VABK1/2---------------- closed
Test Step 2 VLA, VDEBK1/2, VDABK1/2------------- closed
Note
Only if start pressure was positive
After the second test step a leak proof test of the membranes is performed. The
valves have the following position:
VDEBK/VABK:---------------------------- opened
VDABK/VEBK/VLA: ----------------------- closed
Test Step 2a
Note
Test step 2a and 2b only for HDF online machines.
VLA Air separator valve: ------------------ closed
VDFF DF filter valve: ---------------------- closed
VSB Substitution bypass valve: ------------ closed
VSAE Substitution connection inlet valve: - closed
Test Step 2b
VLA Air separator valve: ------------------ closed
VDFF DF filter valve : --------------------- closed
VSB Substitution bypass valve: ------------ closed
VSAA Substitution connection outlet valve: closed
Test Step 3 VLA, VDE, VDA ------------------------ closed
