Description and possible solutions
Signal MVPZN on the MSV board is active. 24 V voltage on the MSV board is too
low, U <18.3 V.
Fuse F1 on the MSV board has burned through.
Reference voltage UREF on the MSV board XT7/1 is too high, U>5 V.
DC/DC transformer of MSV board is defective
24 V current supply from the main power supply unit is excessively strained or
defective.
Anode-cathode voltage is higher than U > 130 V.
MSV is faulty.
Anode-cathode voltage is lower than U < 30 V.
Fuse F4 on the MSV board is defective.
MSV is faulty.
Signal MFSZH on MSV board is active. Suppressor signal control input is too high.
Suppressor voltage is short circuited (cable, ion accumulator)
MSV is faulty.
Suppressor potential is greater than 363V.
MSV is defective.
Suppressor potential is lower than U < 297 V.
Short circuit in suppressor line.
MSV is faulty.
High-impedance short circuit in the ion collector.
The actual anode potential exceeds its nominal value by 10%. The nominal value
can be displayed in the service menu (in "Info")
MSV is faulty.
MC 68 is defective
The actual anode potential has dropped below its nominal value by 10%. The
nominal value can be displayed in the service menu (in "Info")
Brief pressure increase in the mass spectrometer.
MSV is faulty.
MC 68 is defective
Signal MFAZH on MSV board is active. Reference size of the anode potential is
too great.
Brief pressure increase in the mass spectrometer.
Valve contamination causes briefly a high mass spectrometer pressure.
Anode voltage has been short circuited.
Nominal value of the anode voltage is too high. Anode voltage is limited to about
1,200 V.
