PRODUCT HANDBOOK
C7061 A/F
DYNAMIC SELF CHECK ULTRAVIOLET FLAME DETECTOR
APPLICATION
The  C7061A  is  a  dynamic  self-checking flame detector  for 
sensing  the  ultraviolet  radiation  generated  by  the  combus-
tion of gas, oil, or other fuels.
This flame detector is available in two versions:
model C7061A for use in Standard applications, and model 
C7061F  for  use  in  installations  requiring  explosion-proof 
packaging.  The flame detector  is  designed  for  use  with...

GENERAL
DESCRIPTION
The  C7061Axxxx  and  C7061F1xxx  detector  models  are 
identical except for housings.
Model  C7061F  detector  is  for  use  in  installations  requiring 
explosion  proof  packaging.  The 
housing  is  conform  the 
EExd  IIC  T6  classification.  More  details  for  the  explosion 
proof  housing  can  be  found  in  the  chapter  Standards  and 
Approvals. 
The C7061F model has a 1-inch NPT tapping for mounting 
onto a sight pipe. For allowable mounting...

INSTALLATION AND OPERATION
PLANNING THE INSTALLATION
Proper flame detector application is the back of a safe and 
reliable flame safeguard  installation.  Refer  to  the  burner 
manufacturer’s instructions as well to those included here.
Follow all instructions carefully.
CAUTION
1.  Do  not  connect  these  detectors  to  non-Hon-
eywell manufactured controls (primaries, pro-
grammers,  multiburner  systems,  and  burner 
management  systems).  Unsafe  conditions 
could result.

IMPORTANT
When installing the detector, make sure it does 
not respond to ignition spark.
Single burner requirements
The  detector  must  have  an  unobstructed  view  of  the flame 
it  is  supervising  under  all  firing  conditions. This  implies  a 
proper  sighting  angle  and  the  minimization  of  screening 
effects.
Sighting angle
The  first 30  percent  of  a  flame (the  root)  radiates  the  most 
intense  ultraviolet  energy.  The  low  angle  sighting  permits 
the...

INSTALLATION
CAUTION
1. lnstaller must be a trained, experienced flame 
safeguard control serviceman.
2.  Disconnect  power  supply  before  beginning 
installation  to  prevent  electrical  shock  and 
equipment damage.
3.  All  wiring  must  comply  with  applicable  local 
electrical codes, ordinances and regulations.
4.  Voltage  and  frequency  of  power  supply  con-
nected  to  this  detector  must  agree  with  the 
values marked on the detector.
6.  On  multiburner...

IMPORTANT
The  notch  and  arrow  on  the  faceplate  must  be 
aligned in a vertical plane with the notch up and 
the arrow pointing down.
The housing must be mounted with the conduit 
opening  approximately  45°  below  horizontal 
(see Fig. 7)
To mount a C7061A (Fig. 8):
A  The mounting flange is in two pieces. Loosen (but do not 
remove) the three screws holding the flange together. B 
Slightly  rotate  the  detector  so  the  slots  in  the  back  sec-
tion  of  the  mounting...

WIRING
CAUTION
When using a C7061A/F with an R7061 or R7861 
Dynamic  Self-Check amplifier,  be  careful  not  to 
short  the  white  shutter  lead  wires  together  (by 
wiring incorrectly, leaving an incorrect jumper wire, 
or  stripping  the  insulation  too  muc
h  so the  bare 
lead wires can touch).
If  the  shutter  leadwires  are  shorted  during  the 
operation,  the amplifier can  be  permanently 
damaged and nonoperative.
1.  All  wiring  must  comply  with  applicable...
