7.2 Error messages
Errors are events that the device cannot correct itself. Errors force an inter-
ruption in operation.
W160 Leakage rate too high! Switch made to
Standby to prevent contamination!
– The monitor function "Gross leak protection" is activated and a leakage rate above the set limit value has been
detected.
– Gross leak.
– Switch-off limit value too low.
– Alarm delay set too short.
W161 Maximum evacuation time exceeded! – Within the set evacuation time the "measure" mode has not been reached.
– Evacuation time is adapted incorrectly to the volume of the test object.
– The test object has a gross leak.
– Switching pressures set incorrectly.
W162 Excessive increase in inlet pressure p2 dur-
ing AUTO-TEST!**
– Gross leak
– AUTO TEST** delay time is too short

No. Message Possible error sources
E21 Suppressor voltage reference value too high. – The suppressor voltage has been affected by a short circuit.
–MSV is defective.
E22 Setpoint of anode potential too high! – Brief increase in pressure in the mass spectrometer.
– Valve contaminations cause high mass spectrometer pressure.
– The anode voltage is short-circuited.
– The nominal value for the anode voltage is too high. 
The anode voltage is limited to 1,200 V.
E24 24V voltage at MSV board is too low! – Fuse F1 on the MSV board is blown.
– MSV board defective
– 24 V supply voltage from power supply unit too heavily stressed or faulty.
E25 Filament current is too high! – MSV board defective.
E26 Filament current is too low! – MSV board defective
– Defective ion source connector or cable.
E27 Emission fail – Inrush of air
–Valves contaminated
– Failure of a filament during measurement
E28 Emission for both filaments cannot be
switched on!
– Both filaments defective. Replace ion source.
– Defective ion source connector.
– MSV board defective
E29 The anode potential has risen above the set-
point by over 10%.
–MSV is defective.
– MC 68 defective
E30 The anode potential has dropped below its
nominal value by over 10%.
– Brief increase in pressure in the mass spectrometer.
–MSV is defective.
– MC 68 defective
