The S702, S706, S802, and S806 viewing heads do not have 

a safety function. They are used to provide flame intensity 

information via cables to Signal Processor Models 531AC, 

531DC, 532AC, 532DC, 700AC, 700DC, and 800 which use 

Flame Relays to provide a safety function.

The proof test must be conducted every 1 to 5 years. This 

range is given to allow for the test to be performed during the 

normally scheduled burner shutdown period. It is the 

responsibility of the user to perform the proof test in the 

specified time frame.

The following diagrams present the dependence of the 

PFD

AVG

 on the proof test interval. The PFD

AVG

 increases as 

the proof test interval increases.

1. 700 or P532 Signal Processor connected to the S702, 

S706, S802, or S806 viewing head.

2. DC power supply for DC model signal processor and AC 

power supply for AC model.

3. A source capable of generating UV or IR signals as 

required.

1. Ensure the S702, S706, S802, or S806 viewing head 

under test is correctly connected to a compatible signal 

processor.

2. While performing the proof test, disconnect or disregard 

the signal processor outputs so that any outputs due to 

testing do not affect the overall safety system and 

potentially cause a hazardous situation.

3. Record all previously entered user programmable 

settings so that you can restore them to their desired 

values after the proof test.

1. Apply power to the signal processor, fully illuminate the 

viewing head with the light source, and ensure that a 

flame on condition is indicated by the signal processor. 

2. Gradually angle the light source away from the viewing 

head. Ensure that the count decreases until a flame off 

condition is indicated by the signal processor.

3. Cover the end of the viewing head with your hand and 

ensure that the signal processor indicates a flame count 

of zero. 

4. For model 531AC, 531DC, 532AC, and 532DC, signal 

processors, use your light source to generate a 

flamecount of between 1200 and 2800, and note the 

flamecount. For model 700AC, 700DC, and 800 signal 

processors, use your light source to generate a 

flamecount of between 12 and 22, and note the 

flamecount.
