  WARNINGS 

Warning Description  Possible 

Cause

Possible 

Actions 

Electronics 
Temperature 
Low 

The internal 
electronics 
temperature sensor 
has failed to a low 
value. The valve may 
not reach specified 
performance. 

Internal fault. 

Replace the valve. 

Fuel Gas 
Pressure High 

The Fuel Gas 
Pressure value 
exceeds the fuel gas 
pressure high 
warning threshold. 

Warning threshold 
improperly configured. 
 

 
 

Pressure regulator 
adjusted too high. 
 
Faulty or slow pressure 
regulator. 

Configure warning 
threshold for value 
appropriate to the 
application. 
 
Adjust pressure regulator. 
 
 
Verify proper pressure 
regulator operation. 

Fuel Gas 
Pressure Low 

The Fuel Gas 
Pressure value is 
below the fuel gas 
pressure low warning 
threshold. 

Warning threshold 
improperly configured. 
 
 

 

 
Improper engine 
shutdown sequence. 

Configure warning 
threshold for value 
appropriate to the 
application and the 
elevation of the site. 

 

Verify proper engine 
shutdown sequence. 

Fuel Gas 
Pressure Sensor 
High 

The Fuel Gas 
Pressure sensor has 
failed to a high value. 
The fuel gas pressure 
value is derived from 
the default 
downstream pressure 
table instead. 

Internal fault. 

Replace valve. 

Fuel Gas 
Pressure Sensor 
Low 

The Fuel Gas 
Pressure sensor has 
failed to a low value. 
The fuel gas pressure 
value is derived from 
the default 
downstream pressure 
table instead. 

Internal fault. 

Replace valve. 

Fuel Gas 
Temperature 
High 

The Fuel Gas 
Temperature value 
exceeds the fuel gas 
temperature high 
warning threshold. 

Warning threshold 
improperly configured. 
 
 

 

Fuel temperature is above 
warning threshold. 

Configure warning 
threshold for value 
appropriate to the 
application. 
 
Correct fuel temperature 
problem. 

Fuel Gas 
Temperature 
Low 

The Fuel Gas 
Temperature value is 
below the fuel gas 
temperature low 
warning threshold. 

Warning threshold 
improperly configured. 
 
 

 

Fuel temperature is below 
warning threshold. 

Configure warning 
threshold for value 
appropriate to the 
application. 
 
Correct fuel temperature 
problem. 

Fuel Gas 
Temperature 
Sensor High 

The Fuel Gas 
Temperature sensor 
has failed to a high 
value and the default 
fuel gas temperature 
is being used instead. 

Internal fault. 

Replace valve.
