■ TIMING CHART
NOTE:
1. For sensors without built-in timer
functions, operation follows the
NORM mode shown with multifunction time delay models.
2. T1, 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 ONand OFF-delay time settings will be
the same.
4. For ON- and OFF-delay models (part
numbers ending in “D”), T1 and T2 are
independently variable.
5. O.S.D.: one shot delay
