Description
In addition to the 2-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 connected to Y22.
• 2 sensors, each with one contact (2x 1-channel)
(NC/NC). Here, the sensors are "AND"- connected
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.
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).
• 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).
