VPS

VPS Test Failure Valve 2 proving sequence 

has failed.

1.) Check the piping train (is MOV closed, 
piping flanges tight, O-ring leakage), main 
electronics wiring and Pressure Module 
connection to it. For wiring, refer to the 
installation instructions, 32-00018. Reset 
valve and repeat the VPS test.

2.) If fault persists, check system gas 
pressure and repeat the VPS test.

3.) If fault persists, replace Pressure 
Module.

4.) Accept new Pressure Module on the 
PRESSMOD tab in the Setup & Tests 
menu.

5.) Recommission the Hi-Gas and Lo-Gas 
pressure limits. Repeat leak detection test.

6.) If fault persists, replace valve.

Warning 
indication 
for SV2 
valve. 
But this 
condition 
will likely 
cause a 
burner 
controller
