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.
• 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 (external pressure switch S4')
• Remote pressure sensing (switch S'):
• LAN control: The compressor is controlled via a local network. Consult Atlas Copco.
