11. MAINTENANCE AND TROUBLESHOOTING
The supply needs minimum maintenance. Depending on the dust levels in the environment where
the device is being operated, a periodic check of the vents on upper and lower side of the device
and outlet of the fan is desirable. In case of dust contamination it can be cleaned by means of a
vacuum cleaner.
For repair the supply should be shipped back to Saes Group S.p.A..
11.1. IP troubleshooting
During a running mode of the ION pump these messages may be displayed:
(for more details see Cap. 7)
 Arcing - The message will appear after automatic switching off of the power supply due to
either an unstable electric arc in ion element or an arc of high voltage in the circuit of ion
element cable. In this situation, the power supply will try to switch on and if the third attempt is
not successful, the supply remains permanently switched off with error report. The remedy is to
forepump to higher vacuum or to remove the reason of arcing. It is possible to switch on the
supply unit again by pushing the START/STOP pushbutton.
 Over Temperature - The supply is switched off as a consequence of overheating the generator
HV. This circumstance can occur at high ambient temperature and simultaneously maximal
output power of the supply.
After decrease of inner temperature the supply will start automatically again.
If the failure lasts too long time or it appears too often the reason for it might be:
Excessive high ambient temperature.
–
Reduce the ambient temperature or load of the supply.
An insufficient flow of cooling air through lateral grids
–
Ensure a sufficient air flow, leave the supply switched on.
 Low Voltage - The supply is switched off as a consequence of low mains voltage (under low
margin of working extent) apparently at high output power.
As long as this state remains it is probable that the failure message and operating regime will
change periodically until sufficient mains voltage is ensured.
Warning
In the case the HV cable is disconnected, the current will be 0 nA.
