Positioning The Sensor; Twilight Sensor; Indoor Sensor - Kerbl 345000 Bedienungsanleitung

55
You can connect the following components to the light control terminals:
• buttons: Any buttons that are normally open (contact is closed when the button is pressed and open
when it is not pressed)
• light sensor: Use the light sensor that is included in delivery.
Additional light sensors are available from Kerbl.
• lights: Please note the following when choosing lights:
• maximum power output of circuits 1 and 2: 3 kVA each
• maximum power output of circuits 3 and 4: 3 kVA together
• lights with cos φ min. 0.8
• the input surge current of the lights must not exceed 30 A for maximum 5 ms in any light circuit

6. Positioning the sensor

Please plan the positioning of light sensors with care. If the sensor does not supply the right signals, the light control
may not be able to perform well in the control mode to which it is set. Avoid interference from other light sources.
You have two options for positioning the light sensors:
• outdoors (twilight sensor) for the TWILI control mode
• inside the building (indoor sensor) for the AUTO control mode
Please ensure that your desired control mode is set correctly for the circuit, as described in section 9.2.
In Advanced Settings in section 10.1, you can find out how to adjust the sensor readings. You can adjust the settings
in order to adapt the readings to the sensor's installation location.

6.1 Twilight sensor

For the TWILI control mode, position the sensor in a suitable location outdoors.
The sensor must not be under the influence of other light sources. Therefore, avoid influence from
• outside lights on the building itself or other buildings
• street lights
• light cast from windows
• possible headlights from passing vehicles
• any other interfering light sources
Also avoid any possibility of the sensor being overly concealed by large objects. Furthermore, there must be no feedback
with the controlled light circuit. Avoid sensor installation locations in which the brightness changes with the controlled
light circuit. This could be near windows, for example.

6.2 Indoor sensor

If you wish to measure the brightness inside the building using the AUTO control mode, position the sensor in a suitable
location in the same area as the lights you wish to control. The sensor is designed to measure the basic brightness in
the room, and must not receive any interference from local light sources. Therefore, do not position the sensor
• directly in the path of rays of light
• close to a window through which extraneous light may come
• within range of light cast from vehicles
• immediately next to other (uncontrolled) lights
• immediately next to equipment with indicator lamps or a display light
Choose a suitable installation height for the light sensor. Position the sensor sufficiently high to prevent the risk of
shadows cast by passing people, animals or vehicles. Do not position the sensor too high, however, to prevent ceiling
lights from having an excessive influence on readings. As far as possible, position the sensor at the location in the
