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 L20 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-6 is provided with analogue U/I/f outputs for additional PLC or SCADA
connection. For local lighting control 6-channel 230 V AC, programmable, contactor­driving outputs are available. 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 mm2 must be used for 230 V AC power outputs. For
analogue U/I/f outputs and communication coaxial 2-4 lead data cables are recommended.
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!

2. 4. Onboard Indicators

From back side visible LED indicators on PCB indicate current light conditions - green and
contactor output status – red (see Picture 1). Other LEDs are status indicators and have no
meaning for the user.

2. 4. 1. Serial Communication Port

The photometer's selectable communication port can be configured for RS-232 or RS-485.
Set jumpers J1...J3 to select the protocol. Connection distance can be up to 20 m for RS­232 and 300 m for RS-485. Communication supports the complete set of photometer’s
functions, setup parameters and output values.
When serial communication is used for on-line data transfer always choose RS-485. Use
RS-232 for parametric setup or laboratory use only.
