1NC contact + 1NO contact
evaluation / 2NC contact evaluation
-channel connection of aligned
sensor contacts (NC/NC), sensors with opposing
contacts (NC/NO) often used for magnetically
-
operated switches) can also be evaluated. In this
case, please ensure that the NC contact is connected
to Y12 and the NO contact is co
nnected to Y22.
-channel / 1x 2-channel
2 sensors, each with one contact (2x 1-channel)
(NC/NC). Here, the sensors are "AND"-
with one another. Simultaneity is not monitored.
1 sensor with 2 contacts (1x 2-channel) (NC/NC).
Here, it is expected that both contacts open
simultaneously.
Delay time for sensor inputs
During the delay time, sensor signal changes are not
evaluated.
Delay time 50 ms: Changes in the switching
position of strongly bouncing contacts are hidden
(e.g. position switch on heavy protective doors).
Delay time 10 ms: The shorter delay time allows
for a quicker tripping of bounce-free sensors (e.g.
light arrays).
Sensor input automatic start /
monitored start
Automatic start:
The enabling circuits are switched to the operative
position, as soon as the starting condition on
sensor inputs Y12, Y22, Y34 and 1 have been
fulfilled. The start button connection terminal Y33
is not queried.
Monitored start:
The enabling circuits are switched to the operative
position, as soon as the starting condition on
sensor inputs Y12, Y22, Y34 and 1 have been
fulfilled and the start button on terminal Y33 has
subsequently been actuated (start with the falling
edge).
