ADJUSTMENTS AND CHECKOUT
Adjust Detector Sighting
With  the flame detector  installed  and  the  burner  running, 
adjust the sighting position of the detector for optimum flame 
signal. It is suggested that a volt-Ohm meter with a minimum 
sensitivity of one megohm/volt and a zero to five or ten Vdc 
scale  be  used  for  R7861 amplifier  flame signal  measure-
ments.
Measure the flame signal as illustrated in Fig. 11. Be care-
ful  to  make  the  proper  connections  of  positive  (red)  meter 
lead  to  positive  (+)  control  jack  and  negative  (black)  meter 
lead  to  negative  (-)  or  (-Com)  jack  with  7800  SERIES  con-
trols. When the 7800 SERIES control has the keyboard dis-
play  module,  a  zero  to five Vdc  voltage  is  displayed  on  the 
module.
NOTE:  The flame Signal m ust be steady.
Use a W136 test meter (or similar) when measur-
ing the current on an R7061 amplifier . 
Move the detector and sight pipe around to sight the  flame 
from  various  positions  and  angles. Try  to  get  a  maximum 
steady (or stable) reading on the meter. The signal must be 
above the minimum acceptable voltage listed in Table 1.
Measure the  flame signal for the pilot alone, the main burner 
flame  alone, and both together (unless monitoring only the 
pilot  flame  when using an intermittent pilot, or only the main 
burner  flame when  using  direct  spark  ignition).  Also  mea-
sure the  flame signal at low and high  firing rates and while 
modulating in between (as applicable). With the detector in 
its  final  position,  all  required  flame signals  must  be  steady 
(or stable) and as  specified in Table 1. If you cannot obtain 
the proper signal, refer to the Troubleshooting section.
Pilot Turndown Test
If the detector is used to prove a pilot  flame before the main 
fuel  valve(s)  can  be  opened,  perform  a  pilot  turndown  test 
before welding the sight pipe into position. Follow the proce-
dures in the  flame safeguard control instructions and in the 
burner manufacturer instructions.
lgnition Spark Response Test
Test to make certain that ignition spark is not actuating the 
flame relay in the flame safeguard control.
A  Close the pilot and main burner manual shutoff valves.
B  Start the burner and run through the lgnition period. lgni-
tion spark should occur, but the flame LED must not light. 
The flame signal should not be greater than 0.25 Vdc.
C  If the flame relay does pull in, reposition the detector far-
ther  from  the  spark,  or  relocate/resight  the  detector  to 
eliminate/reduce  the  detector  response  to reflected UV 
radiation.  It  may  be  necessary  to  construct  a  barrier  to 
block the ignition spark from the detector view. Continue 
adjustments until the flame signal due to ignition spark is 
less than the flame signal values indicated in step B.
Response to other Ultraviolet Radiation Sources
Some  sources  of  ar tificial light  produce  small  amounts  of 
ultraviolet radiation. Under certain conditions, an ultraviolet 
detector  responds  to  them  as  if  it  is  sensing  a  flame.  Do 
not use an ar tificial light source to check the response of an 
ultraviolet  flame detector. To check for proper detector oper-
ation, conduct  flame failure response tests under all operat-
ing conditions.
Weld the Sight Pipe
When  the  flame signal  is  acceptable  after  all  adjustments 
are made, remove the detector and weld the sight pipe in its 
final  position. (lf you are using a swivel mount, the pipe may 
already be welded). Then reinstall the detector.
Final Checkout
Before putting the burner into service, check out the instal-
lation  using  the  checkout  procedures  in  the  instructions  for 
the  appropriate flame safeguard  control.  After  completing 
the checkout, run the burner through at least one complete 
cycle to verify correct operation.
CAUTION
Do  not  put  the  system  into  operation  until  all 
checkout  tests  in  the  instructions  for  the  appro-
priate flame safeguard  control  and  any  others 
specified in  the  burner  installation  instructions 
are satisfactorily completed.

TROUBLESHOOTING
CAUTION
1. Be  extremely  careful  while  troubleshooting 
the detector; line voltage is present on some 
of the terminals when power is on.
2.  Open the master switch to disconnect power 
before  removing  or  installing  the  detector  or 
its  cover. More  than  one  disconnect  may  be 
involved.
Equipment Required
A volt-Ohm meter with a minimum sensitivity of one megohm 
/ Volt and a zero to five or ten Vdc scale is suggested. When 
the keyboard display module is available, a flame signal dis-
plays on the module. For revision of a flame safeguard con-
trol using the R7061 amplifier, use the W136 or a similar test 
meter. For replacement parts, see specifications section.
UV Sensor Tube Test
see UV sensor tube test section.
Unsatisfactory Flame Signal
If  a  satisfactory  flame signal  (see  Table  1)  cannot  be 
obtained  while  adjusting  the  sighting  position  of  the  detec-
tor,  follow  these  procedures.  If  you  encounter  other  prob-
lems  in  the  system,  refer  to  the Troubleshooting  section  in 
the instructions for the appropriate  flame safeguard control.
NOTE:  For  instructions  for  replacing  the  viewing  window,  sensing  tube,  and  coil  and  shutter  assembly,  see 
the service section.
Troubleshooting Procedures
First  perform  the  preliminary  inspection.  Then  follow  the 
applicable  procedures  for  either  a  low  reading  or  a  zero 
reading  on  the  meter.  After  reinstalling  the  detector  or 
replacing  its  cover,  recheck  the  meter  reading.  To  try  to 
obtain  the  proper flame signal,  adjust  the  position  of  the 
detector.  If  you  complete  all  of  the  procedures  and  still 
cannot obtain a proper flame signal, replace the detector.
Preliminary lnspection
A Check for the proper line voltage. Make sure the master 
switch  is  closed,  connections  are  correct,  and  power 
supply is of the correct voltage and frequency.
B  Check the detector wiring for defects:
a. lncorrect connections.
b.  Wrong type or size of wire.
c.  Deteriorated wire.
d.  Open circuits.
e.  Short circuits.
f.  Leakage paths caused by moisture, soot, or dirt.
C  With  the  burner  running,  check  the  temperature  at  the 
detector. If it exceeds 79°C (175°F):
a. Add additional insulation between the wall of the com-
bustion chamber and the detector.
b.  Add  a  shield  or  screen  to reflect radiated  heat  away 
from the detector, or
c.  Add cooling (refer to sight pipe ventilation and acces-
sories sections).
Removing the Detector from the Sight Pipe
C7061A:
Loosen  the  three  screws  holding  the  mounting flange 
together; rotate the detector slightly so the screws clear the 
slots in the back section of the flange; separate the flange; 
and pull off the back section (with the UV Sensor).
NOTE:  The  detector  will  be  free  as  soon  as  the  collar  is 
unscrewed; do not drop it.
C7061F:
Carefull unscrew from sight pipe
Procedure for a Zero Meter Reading
A  Replace  the  plug-in amplifier.  Then  recheck  the flame 
signal.
B  Replace  the  ultraviolet  sensing  tube  (see  Service  sec-
tion). Then recheck the flame signal.
C  Replace  the  coil  and  shutter  assembly  (see  Service  below). Then recheck the flame signal.
D  If  you  still  cannot  obtain  a  meter  reading,  replace  the 
detector.
