Combination Light Sensor LSR-BW-FUE-01A

Attention! Discontinued type - no longer in production!

Universal digital light sensor for daylight-dependent control and regulation in indoor and outdoor applications.

Quick Facts

  • light control sensor
  • motion detector
  • can distinguish between large/fast and fine movements
  • radio receiver

The LSR-BW-FUE-01A Combination Light Sensor has been specially developed for workplaces and rooms in which the brightness is controlled according to the amount of daylight, activated according to the presence in the room and should also be controllable by remote control. The LSR-BW-FUE-01A is a light sensor with up to 8 programmable setpoints, 8 programmable fixed values, brightness correction and automatic acceptance of the correction as a setpoint. In addition, a motion detector is integrated, which can distinguish between large/fast and fine movements. For remote control, a radio receiver has been integrated to which up to 20 remote controls with up to 4 sub-addresses can be taught. The LSR-BW-FUE-01A works on the ISYGLT subnet. All functions can be evaluated and individually linked by free programming.

Light control sensor
The sensor is designed for indoor light measurement (artificial light measurement) and has a resolution of 10Bit (1024 steps). This makes constant light control simple and convenient. 8 brightness setpoints can be individually stored, which the controller automatically adjusts. If a setpoint is corrected manually and not changed for 10 seconds, this value is temporarily accepted as the current setpoint. The brightness remains constant in this case. This will compensate the ageing of lamps. The individual light levels can be called up both by remote control and by the building automation system (ISYGLT).

Remote receiver
Defined functions are available via radio remote control. Furthermore, it is possible to evaluate all the codes of the FS-10T hand-held remote control listed below in the Master.

Log on FS-10T to LSR-BW-FUE-01A

Preparation of the FS-10T:

  • Set the turn switch on the remote control to position 3.
  • Press FUE button for 2 seconds - LED remains on
  • Press the green button on the remote control (previously set to sub-address 3) - receiver blinks for 2 sec. to confirm

To delete all remote controls, proceed as follows:

  • Press FUE button for 10 seconds - LED on receiver blinks 3x >> all deleted. The required remote controls can now be programmed.

We recommend deleting the remote control entries in the receiver when it is first used.

The button codes of the remote control can be found in the instructions for use.
