UO-SCR-R module
Please see the specific module operating and assembly manuals for further
important information.
The UO-SRC-R is a safe position switch module, and contains 3 position switches. The position
switches open and close depending on the position value. The position switches are 2-channel
(2 normally open contacts, cat. 3). A position switch can be used to create a cam, e.g. a switch-
on and switch-off position, as well as the associated hysteresis switching points.
P1:
Hysteresis switching point
from P2.
P3:
Hysteresis switching point
from P4.
Inverted:
The switch works in an
inverted fashion (see switch S3).
Error switch:
Switch only opens if
there is an error (see switch S2).
Opening in case of an error:
Switch works as configured, but
opens in case of an error.
This graphic shows the switching
points in the correct positions. A
marker indicates the current position.
Conclude configuration of the module
by clicking “Write to device”.
Note
The following condition applies to the position switch points: P1 < P2 < P3 < P4
The entered position values must be
within the working area limits. Each
position switch can be assigned an
application-specific designation (max.
12 characters). The configuration values
are entered into the table as shown
here.
