NOTE: 1. For sensors without built-in timer functions, operation follows the NORM mode shown with multi- function time delay models. 2. T 1, T2 and T denote set time, variable within 0.1 to 5 second range. 3. For multifunction time delay models (part numbers ending in “T”), the ON- and OFF-delay time settings will be the same. 4. For ON- and OFF-delay models (part numbers ending in “D”), T 1 and T2 are independently variable. 5. O.S.D.: one shot delay
