No use of the external signal
If no e
xternal signal is used to activate the safely limited speed (SLS), the B130 SLS
request input operand at input 1 of the AND block must be deleted and static 1 con‐
nected instead.
The corresponding element at the I5 / I6 input of the K100.1 XTIO module can then be
deleted too in the hardware configuration area.
Use of an additional internal signal
If t
he safely limited speed (SLS) is supposed to be activated via an internal logic signal,
static 0 has to be deleted at input 2 of the AND block and the internal logic signal is to be
connected instead. The signal must be logic active High.
7.4.3 Configuring the override function
An override function may be required for some applications. This could be the case, for
e
xample, if safety is guaranteed by another safety function at a particular moment (e.g.,
by a safety laser scanner) or if a brief position detection fault can be knowingly
accepted (e.g., if there is a code jump or relatively large expansion joint).
The pre-configured project file for Flexi Soft Designer is prepared for an override func‐
tion, but does not feature the logic for activating the override function. The user must
develop this for the specific application in question.
NOTE
T
he override function is not part of the safety system. The user is responsible for ensur‐
ing safe implementation.
The requirements for the override function result from the risk assessment that has to
be performed by the user. Proof must be provided that the override function meets
these requirements (e.g., with SISTEMA). The user also needs to verify and validate the
override function.
1. Move the mouse cursor to the L
ogic editor button.
2. Click on Logic editor.
3. Click on the Interface logic page.

4. Replace S
tatic 0 with a signal that has a logical High value when the override func‐
tion is requested. When the override function is requested, all position errors are
ignored.
If an override function is used, the Override request jump address must be used.
