2. 

Guideline for Connection and Use of Photometer 

 

2. 1.  Field of Use 

 
Photometer  is  designed for measuring  and  regulation  of  traffic  area  illumination. Based 
on  L

20

  measurement  according  to  CIE  standard  it  establishes  adequate  illumination  at 

any time of day and any light conditions. Integrated logic controller and software provide 
complete solution for tunnel lighting regulation with no external controller necessary.  
Photometer FM-4 is provided with 4-channel 230 V AC contactor-driving outputs for local 
lighting  control,  programmable.  Full  function  control,  measuring  range,  output  channel 
switching and time averaging interval are PC programmable using software provided. 

2. 2.  Mounting and Placement 

 
Photometer comes with wall/pole fixture; special pole fixture is also available (optional).  
When used for tunnel entrance portal-lighting measurement, the photometer is installed 
at  the stopping  distance  before  the  tunnel  entrance. It should  be  pointed  directly  to the 
entrance.  Mounting  on  pole,  take  special  care  for  proper  pole  grounding,  including  any 
foldings or joints! 
When it is used to measure in-tunnel light conditions, it should be mounted at the height 
of app. 4.5 metres and pointed to the spot one reach in 3 seconds at maximum allowed 
speed.  In  this  case  the  driver’s  view  cannot  be  simulated  accuratley  due  to  mounting 
height and measuring result shlold be adopted by correction factor (usually between 1.05 
and  1.20).  For  in-tunnel  use,  especially  in  long  tunnels  choose  full-stainless  steel 
hausing option. 
Once mounted, undisturbed view-field of the photometer must be provided. There should 
be no light sources, either any light reflecting objects in the view-field of the photometer. 
Any of those can considerably affect light measuring accuracy. 

2. 3.  Connections 

 
Photometer  is  connected  to  the  mains  power  supply  230  V  AC  and  to  the  tunnel  light 
controlling system. All connections are done from the back side with cover removed. Cables 
of 3-9 leads and minimum 0.75 mm

2

 must be used for 230 V AC power outputs. Maximum 

connection distance is up to 400 metres.  
 
After  final  connection  and  successful  commition  place  desiccant  bag  provided  in  the 
photometer’s  housing  and  push  it  towards  front  window.  Take  care  it  is  not  touching  any 
electrical  part!  Cable  inlet-glands  and  back  cover  must  be  well  tightened  after  final 
connection!
