Product Usage Instructions

Safety: – The installation and operation of this luminaire must comply with national safety regulations. – Only a qualified electrician should carry out the installation and commissioning. –
The manufacturer is not liable for damage caused by improper use or installation. – Any modifications to the luminaire should be done by the responsible person, who will be considered the manufacturer.
Overvoltage Protection: – The luminaire’s electronic components are protected against overvoltage according to DIN EN 61547. – For additional protection against transients, it is recommended to use separate overvoltage protection components available on the manufacturer’s website.
Installation: – LED components are high-quality electronic components. Avoid touching the light output opening directly during installation or relamping. – To release the glass from the luminaire housing, turn it counter-clockwise (left) (Das Abnehmen des Glases erfolgt durch Linksdrehung).
Mounting
Height and Range: – The maximum wall mounting height is 2.7 m and the maximum ceiling mounting height is 4.0 m, with a significant reduction in range. – Metal parts mounted close to the luminaire can affect the range. – The range can be set individually using the push-button sensitivity. Adjustments can be made using the integrated push-buttons on the motion sensor
Push-Button
Settings: – The three integrated push-buttons on the motion sensor allow specific settings. – Press a push-button to switch each function to the next level. The LED indicator on the motion sensor flashes to confirm. – After reaching the highest level, the level setting begins with Level 1.
Daylight Setting: – The number of flashes indicates the step or level for the daylight setting. – Level 1 – 1x blink, Level 2 – 2x blink, Level 3 – 3x blink, Level 4 – 4x blink, Level 5 – 5x blink, Level 6 – 6x blink. – Daylight intensity: 300 lx for Levels 1-3, and 150 lx for Levels 4-6. 7.
Teach-In Configuration: – Use the designated button for teach-in configuration. Please refer to the user manual for more detailed instructions and safety information.

Installation

LED are high-quality electronic components!
Please avoid touching the light output opening of the LED directly during installation or relamping.
Pass the mains supply cable through the grommet into luminaire housing.
Fix luminaire housing with enclosed or any other suitable fixing material on to the mounting surface.
It is imperative to use the enclosed gaskets.
Dismantle the mains supply cable approx. 60 mm.
Make earth and electrical connection to the terminals.
Place glass to the luminaire housing and observe that the cam pins fit into the notches of the glass.
Screw in glass by turning it clockwise.
Thus, you reach a safe and vibrationresistant holding of the glass.
To release the glass from the luminaire housing, turn it counter-clockwise.
The built-in motion sensor operates at a frequency of 5.8 GHz.
By moving within the detection range the motion sensor switches on the LED module inside the luminaire with a defined dwell time – push-button “Dwell time”.
With a wall mounting height of 1.8 m or ceiling mounting height of 2.6 m, the maximum range is 10 meters (see sketch).
The max. wall mounting height is 2.7 m and the max. ceiling mounting height is 4.0 m, in which the range reduces significantly.
The range can be set individually – push-button “Sensitivity”.
It should be noted that metal parts which are mounted in close proximity to the luminaire can affect the range.
With the three integrated push-buttons
(Brightness, Dwell time and Sensitivity) on the motion sensor, specific settings can be made.
The first keypress activates the setting function.
Press a push-button to switch each function to the next level, the LED indicator on the motion sensor flashes to confirm.
After reaching the highest level, the level setting begins with “Level 1”.
After the 3 parameters brightness, dwell time and sensitivity have been set successfully the module will require a voltage break to save the changes.
The integrated light sensor can be set individually with the brightness levels on the ambient brightness – Press the button “Brightness”.
Further individual illumination levels can be used with the button “Brightness” and set with the “learning mode”.
Press button “brightness” (> 3 s) to enable the “learning mode”. There is a slow flashing of the LED indicator.
After about two minutes, the current brightness value is measured for one minute, the LED flashes faster.
After completion, the measured brightness value is saved and is available in stage 6 of “Brightness” as the new brightness value.
To simplify the initial operation, the settings have been made as follows:
Range = 75 % (7.5 m)
Dwell time = 10 s
Light sensor = daylight

Factory Reset

The motion sensor can be reset to factory settings (MICAS) by simultaneously pressing the buttons “Sensitivity” and “Dwell time” for about 5 s.
The factory settings are as follows:
Range = 75 % (7.5 m)
Dwell time = 900 s
Light sensor = daylight

Test mode

The test mode can be used to check the change of settings of the motion sensor. Press button “Sensitivity” (> 3 s) to enable the “test mode”.
Each further keystroke of this push-button prolongs the test mode.
The active test mode is displayed by a flashing of the LED indicator (2 s interval).
After 3 minutes the test mode is automatically disabled.

Replacement of the LED unit

The designation of the LED unit is noted on a label in the luminaire.
The light colour and light output of BEGA replacement units correspond to those of the LED units originally fitted. The LED unit can be replaced by qualified persons using standard tools.
Disconnect from main supply.
Unscrew glass from luminaire housing by turning it counter-clockwise.
Replace the LED unit.
Screw in glass by turning it clockwise. Defective glass must be replaced.
