Atlas Copco GA 11+ Instruction Book page 80

On compressors equipped with an Elektronikon™ Swipe controller, the controller is provided with
potential free auxiliary NO contacts (NO = normally open) (K05, K07 and K08) for remote
indication of:
• Manual load/unload or automatic operation (K07)
• Warning condition (K08)
• Shut-down condition (K05)
Example: K05 is a NO (NO = normally open) contact. It will be closed if all conditions are normal
and will open in case of power failure or shutdown.
Maximum contact load: 10 A / 250 V AC.
Stop the compressor and switch off the voltage before connecting external equipment. Consult
your supplier.
Compressor control mode
On compressors equipped with an Elektronikon™ Swipe controller, consult the controller chapter
if it is desired to switch to another control mode.
On compressors equipped with an Elektronikon™ Touch controller, consult section
screen if it is desired to switch to another control mode.
The following control modes can be selected:
• Local control: The compressor will react to commands entered by means of the buttons on
the control panel. Compressor start/stop commands via Clock function are active, if
programmed.
• Remote control: The compressor will react to commands from external switches.
Emergency stop remains active. Compressor start/stop commands via Clock function are
still possible.
Options:
• Remote starting and stopping (switch S1')
• Remote loading/unloading (switch S4')
• Remote pressure sensing (switch S' combined with pressure switch S4')
• LAN control: The compressor is controlled via a local network. Consult your supplier.
See service diagram 9828 5323 50 (9828 5323 51 for Ammann) to locate the connectors.
