Test 5 - Display Switchover Pressure 

The number on the display is the switchover 
(changeover) pressure value that is internally 
set for product operation.  The value is in the 
units of measure selected for the product (PSI, 
BAR, etc.) 

 

 

Test 6 – Auxiliary Settings 

Displays settings for Units of Measure, 
Communication setting, Keypad lockout, 
allow remote settings enable, Reserve Gas 
source enable. 

Refer to Table 9 to determine what is enabled 

 

Test 7 – Delivery Regulator Pressure 
Tolerance 

This number represents the value added or 
subtracted to the nominal delivery pressure of 
the product.  It is used to determine the 
allowable range of operation before a delivery 
regulator fault condition is declared. 

 

Test 8 – Delivery Regulator Alarm Delay 

This value is the number of minutes the 
system waits before looking back.
