[S4] Timer
<Off delay operation>
The output is turned off at the set timer time after the detection becomes off. Therefore, even if the detection
becomes OFF momentarily, as indicated by B, the output does not turn off. This prevents chattering.
Furthermore, setting an Off delay can lengthen the output time in cases where the objects are small and the
sensor only turns on for brief periods of time. The result is that even slow-speed controllers can capture
momentary changes.
„
Pulse output
The pulse output is held for the set timer time from the time the
detection becomes on. The chart on the right shows the pulse
output for 1 second.
„
On/off delay
The On delay and Off delay timers both are activated.
The times for the output switching from off to on and from on to off can both be delayed.
The On delay and Off delay times can be set separately.
„
On delay pulse
The On delay and Pulse output timers both operate.
The time for the output switching from off to on can be delayed, and the on status can be maintained until the
set time elapses.
The On delay and Pulse output times can be set separately.
