(*) In the ‘Check’ column above, alarms are checked:
Constantly—if machine running or stopped
When Running—if machine is running
If Enabled—if parameter is non-zero
At Start—will not allow start if alarm present
Over Min Psi—machine is loaded and above min load pressure
(**) 750 psi for 750 psi transducers.
