the cool down cycle, the compressor stops. If the system is in the Automatic Mode,
the compressor restarts to refill the storage when the system pressure drops about
6200psi below the desired maximum pressure. In contract, if the system is in
Manual Mode, you must press Start on the HMI after the storage pressure drops
about 6200psi from full to restart the compressor to refill the storage.

When the compressor is in Automatic Mode, it restarts when the pressure drops
about 6200psi below maximum system pressure. If the storage pressure was
already full when the system started, the HMI displays Storage Full and the
compressor will still restart automatically when pressure drops.

Provided all compressor operating parameters are within tolerances, the system is
ready to fill breathing air cylinders.
Warning: Never attempt to perform service while the compressor system is in use in
the Automatic mode. When the compressor system is in the Automatic mode, the
compressor will restart when the storage pressure drops approximately 6200psi below
maximum pressure. This can happen at any time without warning. Failure to observe
this warning could result in serious injury or death.
Compressor E-Stop
Button
This section covers the compressor E-Stop button.
This is not the same as the HMI Stop, that provides an orderly compressor shutdown.

In case of an emergency, press E-Stop button. This automatically stops the
compressor. The compressor locks and is unavailable for four (4) minutes after the
Emergency Shutdown button is activated.
Warning: Use of the Emergency Shutdown button stops the compressor immediately
without the benefits of a two minute cool-down cycle. In the Emergency Shutdown
mode, the compressor is locked out and unavailable for four (4) minutes. Repeated use
of the Emergency Shutdown results in residual moisture in the system which may result
in serious damage to the equipment.
