7 Operating instructions
7.1 Before initial start-up
Safety
The operator must apply all relevant safety precautions, including those mentioned in
this book.
Outdoor/altitude operation
If the compressor is installed outdoors or if the air inlet temperature can be below 0 °C , precautions must be
taken. In this case, and also if operating above 1000 m , consult Atlas Copco.
Moving/lifting
The compressor can be moved by a lift truck using the slots in the frame. Take care not to damage the
bodywork during lifting or transport. Before lifting, reinstall the transport securing bolts. Make sure that the
forks protrude from the other side of the frame. The compressor can also be lifted after inserting beams in
the slots. Make sure that the beams cannot slide and that they protrude from the frame equally. The chains
must be held parallel to the bodywork by chain spreaders in order not to damage the compressor. The lifting
equipment must be placed in such a way that the compressor is lifted perpendicularly. Lift gently and avoid
twisting.
In case of units equipped with the Lifting Device Option, it is not allowed to lift the
compressor if the canopy parts or lifting supports are not completely installed. When the
compressor is being lifted, it is also forbidden to come under the load or to perform
maintenance activities to it.
Compressor status indication on compressors equipped with an Elektronikon® Graphic controller
The controller is provided with auxiliary contacts (K05, K07 and K08) for remote indication of:
• manual load/unload or automatic operation (K07)
• warning condition (K08)
• shut-down condition (K05)
Maximum load for the contacts: 10 A / 250 V AC. Stop the compressor and switch off the voltage before
connecting external equipment. Consult Atlas Copco.
Compressor control modes
Stop the compressor and switch off the voltage before connecting external equipment.
Only voltage-free contacts are allowed. Have the modifications checked by Atlas Copco.
The following control modes can be selected:
• Local control: The compressor will react to commands entered by the buttons on the control panel
Compressor start/stop commands via Clock function are active, if programmed.
