2. Guideline for connection and use of photometer
2. 1. Field of use
Photometer is designed for measuring and regulating illumination in traffic areas. It
provides adequate ilumination at any time of the day and any light conditions. Its basic
application is to regulate the illumination of tunnels and under passages based on L
20
measurement according to CIE standard. Photometer FM-1 is provided with analogue
U/I output for PLC or tunnel SCADA connection. For local illumination controll 4-channel
230VAC programmable outputs are available. Measuring range, output channel
switching and time averaging interval are PC programmable using provided software.
2. 2. Mounting and placement
Photometer is equipped with wall fixture. Pole fixture is also available (optional).
For measuring light conditions at the entrance of the tunnel the photometer is installed at
the stopping distance before entrance portal. It should be pointed directly to the entrance
of the tunnel.
When used to measure in-tunnel light conditions, the photometer should be mounted at
the height app. 4.5 metres and pointed to the spot one reach in 3 seconds at maximum
allowed speed. In this chase the driver’s view cannot be simulated very accurate due to
mounting height. Therefore, the measuring result must be adopted by multiplying with a
constant number (usually between 1.05 and 1.20).
Once mounted, undisturbed view field of the photometer must be provided. There should
be no disturbing objects in the view field of the photometer, either any light sources or
light reflecting objects in near distance. Any of these can considerably affect light
measuring accuracy.
2. 3. Connecting
Photometer is connected to the mains power supply 230 VAC and to the tunnel light
regulating system. Cables with 3-7 leads at minimum 0.75 mm
2
must be used for 230 VAC
power outputs. For analogue U/I output coaxial 2-3 lead data cable is recommended.
Maximum connection distance is up to 400 metres. Cable inlet via glands must be well
tightened after the connection. For the parametric setup connect photometer with personal
computer and run software. Connection distance can be up to 20 metres for RS-232 (200 m
for RS-485 –optional).
All necessary connectors are accessible by removing rear cover (see Pictures 1 and 2and
Table 1).
After final connection and successful commition place provided desiccant bag in the
photometer housing and push it towards front window. Take care it is not touching any
electrical part!

2. 4. Onboard indicators
Beside connectors there are LED indicators on the PCB board (seePicture 1). They indicate
current light conditions (green) and contactor output status (red).
2. 4. 1. Use of 230 VAC contactor outputs
Those outputs can be directly connected to the coil side of contactors for light-chain
switching (check contactor’s coil voltage). Use provided software to distribute switching
combinations regarding to light condition. Example is shown at Table 2.

Table 2: Indicating LEDs and contactor outputs
Four green LEDs indicate current light level switch combination (no averaging delay)
regarding to light condition. For example : At first level there is LED 1 lit in second LED 2 is lit
in third LED 3, etc. Red LEDs indicate current status of 230 VAC outputs (averaging
affected).
Light levels, output combinations and averaging interval are software adjustable (referto
PC software).
2. 4. 2. Use of U/I analog outputs
Analogue outputs directly follow current light conditions (no averaging is applied). There are
two outputs for this purpose: voltage (0-10 V) and current (4-20 mA). Simultaneous use of
both is not recommended and can affect accuracy. 230 VAC contactor outputs can be used
at the same time with no affect to accuracy. (For example: tunnel lighting can be switched
on/off by using contactor outputs while light conditions are monitored via analog outputs
connected to SCADA). For distance over 100 metres use of I-current output is preferred. For
brightness calculation use following equations:
B(U)=B
range
*(U-U dc
range
)/(10- U dc
range
)
B(U ) = brightness at output voltage U(cd/m

Using individual calibration constants is always preferred for best accuracy.
When using analog outputs “fix-range” optionshould be chosen when programming (seePC
software) and relevant range applied in equations!
Calibration constants are placed on thecalibration sticker at the side of photometer.
2. 5. Calibration
Each photometer is individually factory pre-calibrated. Last calibration date and calibration
constants are stored in photometer’s memory and can be read using PC program. They are
also visible on the calibration sticker at the side of the photometer. Recommended
recalibration interval is 3 years.

3. PC software
Software FM-1v1.1.exe is used to monitor photometer condition and to configure working
parameters using PC. Install the software to any folder on the computer running MS
Windows 2000 or higher. By clicking the icon FM-1 window like shown at Picture 3 appears.

The “System settings” button is used for factory calibration and testing. It has no
meaning for the user.

3. 1. Setting up PC communication
Photometer should be connected to the computer via serial COM port using RS-232 (485)
protocol. Cable length can be up to 20 metres (using optional RS-485 up to 200 m).
In the upper right corner of the screen there is a field for adjusting communication
parameters. COM1 is selected as default. If port is already occupied by other device the
message “Port closed!” appears. In this chase select another port and click “Open port”.
If port is successfully open, the message "Port OK!" appears. Communication speed is
fixed at 9600 bps. When communicating, photometer must be powered on!
In the upper left corner of the screen there is a field to select the photometer’s ID
number. This is used to identify the device when there is more than one photometer
connected on the bus (RS-485). Use last two digits of the device’s serial number (see
back side sticker) for ID.
3. 2. Writing data to the photometer
Left part of the screen contains data to be written into the photometer (black font), right
side shows data read from the photometer (red font). By clicking “Write” button all data
consisting of 16 contactor-switch combinations, range, averaging interval and other
parameters are downloaded to the photometer. Data is only applied to device with
accurate ID number. When download is done successfully red numbers as read data
appears on the right side of the screen. If there is an error at the procedure “Error!”
message appears. In this chase check ID number and try clicking “Write” button again.
Range
Use “Range” setting to define measuring range of the photometer. Always use lowest
possible range, taking care brightness never exceed the range specified. In “auto” mode
photometer switches ranges according to light conditions. Use this option when
brightness data is acquisition is done from RS232/485 or contactor outputs. When using
analog outputs, make sure to choose fixed range R1-R3 and match range in equations.
Default factory setting for range is full measuring range –R3.
Contactor out
A contactor combinations field Level 1-16 represents the upper limit of brightness (cd/m
2
)
for the level. You can use only numerical data. When the option “Expander” is selected
the software fills the contactor-output combinations like BCD code. Use this option when
optional Expander unit is used to controll more than 4 light chains. In this chase
contactor-combinations are programmed at Expander unit.
The contactor-output combinations can be set for each level independently when option
“Custom” is set. When using less than 16 brightness level combinations, fill the rest of
the Level data with zero, and Level 16 with combination used when brightness at any
level specified are exceeded. (see: Picture 4, Table 2).

Picture 4: Contactor output example
Averaging
Averaging interval represents the time in minutes for brightness-averaging before
contactor outputs are switched. This eliminates contactor switching due to short-time
light changes (approaching car, ect.) and provides hysteresis between the brightness
levels. The numerical data between 0 and 12 minutes can be selected.
3. 3. Reading data from photometer
By clicking “Read” button data is read from photometer. Data is only read from device
corresponding set ID. After reading is done successfully red numbers as read data
appear on the right side of the screen. Brightness data is not affected with averaging
interval.
