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-4 is provided with analogue
U/I output for PLC or tunnel SCADA connection. For local illumination controll 6-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.

Four green LEDs indicate current light level switch combination (no averaging delay)
regarding to light condition. For example : At first level thereis LED 1 lit in second LED2 is lit
in third LED 3, etc. Red LEDs indicate current status of 230 VAC outputs (averaging
affected).
Light levels, outputcombinations and averaging interval are software adjustable (referto
PC software).
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 (individually calibrated 2 years).
