The p1 Pressure Band Setting screen is shown in Figure 57 below. The bar graph gives a visual indication 
of the pressure band settings. Press the numerical value boxes to make adjustments as needed. Note that 
the minimum and maximum values that will be allowed for each box will change dynamically based on the 
design pressure of the machine as well as the values of the other settings. For example, to increase the 
Load pressure to 126 PSI in Figure 57, the Unload pressure and Target pressure would first need to be 
increased. 
 
 

 

Figure 57: Primary Pressure Band Setting 

Once you are satisfied with the pressure band settings, press the 

Save

 button to commit the changes. 

 
One thing to note, when the certain machine settings are changed a (*) will come up next to the changed 
setting indicating the changes are made and pending to save. Hit the 

Save

 button at bottom to implement 

the changes and the (*) will go away when changes are confirmed. 
 

3.7 Clearing Alarms 

 
If there are any faults present on the machine, they must first be cleared to allow the machine to be started. 
If the machine has been powered on recently and Auto Restart is not enabled, a Power Loss fault will be 
present.  
 
If a fault is active on the machine, the  Active Alarms  screen can be accessed by  pressing  on the  Alarm 
triangle on the Message Status Bar on the Home screen, or by navigating to Alarms > Active Alarms through 
the Menu. The Active Alarms screen is shown in Figure 58. 
 
If the alarm icon in the Alarm column is an outline, as shown in Figure 58, the alarm is no longer active and 

may be reset. If the alarm icon is solid (

), the fault is still active and the condition must be resolved 

before it can be cleared. 
 
Once all faults have been resolved, press the 

Reset All

 button, which will move the alarms to the Alarm 

History screen. Once all faults have been reset, return to the Home screen.
