DIP switches located on the timer card provide the user with a choice of seven delay functions including dual
delay and motion detection. In addition, light operated or dark operated sensing can be selected by a switch
located on the photoelectric sensor head.
TIMEDELAYOPTIONS
The timer/logic cards can be set up to modify the sensor’s head output signal. For instance, in thru-scan or
reflective scan (L.O. mode), if the logic card is set for OFF delay the sensor does not immediately turn off its
output circuit after the beam goes dark or is blocked. Instead it waits until the beam has been dark for a preset
time.IfsetforONdelay,thesensorwaitsforapresettotimetorecognizethatthebeamiscomplete.

In addition, the timer/logic card offers four modes of operation: 1-shot, a delayed 1-shot, 1-shot drop, and a
delayed 1-shot drop. The cards can be adjusted for both the width of the 1-shot pulse and the length of delay
beforethe1-shotisred.
TIMINGOPTIONSETTINGS
