If these discharges are not avoided there is the danger of:
• injury to/incapacitation of operators and maintenance staff
• spark formation
• damage to the AirBox
• damage to the electrical equipment
The electrical triggering has priority over the mechanical
triggering.
Operation
Check the safe functioning of the unit. Display by LEDs:
• LED green: supply voltage via the AS-i system
• LEDs yellow: external voltage supply
For trouble-free operation sufficiently treated air must be used (filtered
air 5µm, lubricated (ISO-VG10)1) or not lubricated). Once the AirBox
has been operated with lubricated air, it always has to be operated
with lubricated air as the oil removes the initial lubrication.
1) You can find further notes on compressed air and EMC/ESD for the
AirBox at www.ifm-electronic.com. Enter the article number of your
AirBox on the start page under "Data sheet direct". You receive the
additional product information by clicking on "Additional data".
Depending on the unit version the exhaust air is filtered with a sinter-
ed exhaust or leaves via a common exhaust.
