DANLERS CESR PIR Installation guide

  • Hello! I've reviewed the product details for the DANLERS CESR PIR occupancy switch. This document provides information on its features, installation, and troubleshooting. This device includes a passive infrared quad sensor, adjustable time and lux settings, and the ability to handle various load types. I am ready to answer your questions about this PIR switch.
  • What types of loads can the PIR switch?
    How can I adjust the ambient light threshold for the switch?
    What is the warranty period for this product?

Troubleshooting
The load will not switch on:
• TheLUXadjusterissettoolowandisinhibitingtheswitch.
• TheSENSadjusterissettoolow.
• ThemovingbodyisnotemittingmoreIRthanthebackground.
  (Personwearinginsulatingclothinginawarmenvironment)
• PersonistoofarfromthePIRswitch,seedetectiondiagram.
• Personismovingunusuallyslowly(perhapswhentesting).
The load switches on when nobody is present:
• Heatercausinginfra-redvariationsinasmallcoldroom.
  Reducethesensitivityadjusterorre-sitetheCESRPIR.
