W66 Gate interrupt of the booster-
TMP converter is missing!
"Frequency converter is faulty",
"Booster-TMP is faulty",
W67 Booster-TMP runup time
exceeded!
"Frequency converter is faulty",
"Booster-TMP is faulty",
W69 Booster-TMP frequency is
too high!
"Frequency converter is faulty",
"Booster-TMP is faulty",
E73
Emission off (p2 too high)
PV >> 0.2 or 3 mbar due to an inrush, e. g. The UL5000 will again try to
resume the measurement mode.
W76 Maximum of evacuation time
was exceeded.
•
Test sample has got a GROSS leak.
•
False adjustments of the max. time of evacuation.
W77 Peak not in Range
The signal maximum has shifted to mass range alignment limits.
•
Signal of leak rate was instable during mass adjustment. Calibrate
again.
•
Check the basic setting for the anode voltage through the service
menu.
•
Check calibrated leak.
W78 Differences of signal between
test leak open and closed is
too low.
The amplifier voltage difference between opened and closed calibrated
leak is less than 10 mV. Calibrated leak has not been closed properly.
W79 Signal of test leak is too small Calibrated leak is too small or has not been opened. Preamplifier voltage
< 10 mV.
W80 Please calibrate machine
newly
The automatic request of calibration is activated (See Chapter
) and
has fulfilled at least one of the conditions:
•
30 minutes are passed since energizing.
•
Temperature of the pre-amplifier has changed more than 5°C since the
last calibration.
•
Mass adjustments were changed.
W81 CAL Factor too low
The calculated factor falls out of the valid range (<0,1). The old factor is
retained.
Possible fault cause:
•
The conditions for calibration have not been maintained.
•
The leak rate of the internal calibrated leak which was entered is much
too small.
•
The internal test leak is defect.
W82 CAL Factor too high
The calculated factor is out of the valid range (>10). The old factor is
retained.
Possible fault cause:
•
The conditions for calibration have not been maintained.
•
The leak rate of the internal calibrated leak which was entered is much
too high or much too small.
No.
