Error No. 1 - PRel not achieved / Cause + Remedy ?
Possible cause:
The required filling pressure in the test volume could not be adjusted within
the test program tolerances for Prel (= relative
pressure)
Possible remedy:
-
The main system pressure is less than the required test pressure =>
Increase main system pressure
-
There is a very large leak. In this case it can happen that the filling
pressure is not reached within the tolerance Limits => Eleminate
leakage
-
Pressure regulator is de-adjusted
in the actual value or setpoint => Check with pressure calibrator and
adjust the pressure regulator if necessary
-
Actual value signal of pressure
regulator defective => Replace pressure regulator and re-adjust actual /
nominal
-
Setpoint signal of pressure
regulator defect => Replace pressure regulator and re-adjust actual /
nominal
-
Mechanical fault in the pressure
regulator => Replace pressure regulator and re-adjust actual / nominal
-
Test program tolerances for Prel
too low => Adjust tolerances in the test program
