5. Maintenance
Warning!
Electric shock hazard!
• Do not carry out any maintenance or repair work without first discon-
necting the supply voltage of the units.
• The machine which has the units fitted must not be in operation.
• The bars passively absorb energy from the moving substrate web. The
high voltage cable must be plugged in or grounded to the power supply.
An unconnected grounding cable may cause a spark discharge and
may lead to a risk of injury.
• Repairs and maintenance work must be carried out by qualified person-
nel only.
To ensure the trouble-free function of the discharging bars, clean the bars
at least once a week with compressed air free of oil and water (max.6 bar
and standard compressed air pistol) and a brush with soft plastic bristles.
Clean grease, ink, glue, paper dust, etc. off the discharging bar and the
distance detection using a suitable solvent (benzine). Do not soak the
bars and the high voltage cable in solvent!
Caution!
Do not damage the emission tips when cleaning. Brush only in longitudinal
direction.
Warning!
Risk of deflagration!
Allow the solvent to evaporate completely before restarting the unit.
Inspection of the protective resistors
The function and the appearance of the protective resistors must be
inspected at regular intervals. The inspection intervals are specified in the
accident prevention regulations, as amended (e.g. in Germany DGUV
V3). Eltex recommend inspection intervals of 6 months.
The function of the series resistors must be checked using a suitable
measuring device. The test voltage must be 1,000V. The measured resis-
tance between two emission tips of the same tip row must not fall below
240 MOhm and not exceed 360 MOhm.
