1.
Apply the test signal during back‐
ward movement.
2.
Set test signal 1 “forward” to
active (XTIO input I1).
3.
Set test signal 2 “backward” to
inactive (XTIO input I2).
The safety system switches to the safe

Thorough check of the safety functions
External signal for requesting the safely limited speed (SLS) (if external signal used)
NOTE
You must undo the manipulation on the safety system again after each individual test
sequence. Then you must reset the safety system and carry out a restart.

Check sequence
Expected result
Result OK?
1.
Check that the external signal
source activates the SLS safety
function (outputs of the signal
source = 0 V).
A safe stop 2 (SS2) is initiated at a
speed > speed ID 2.
An automated restart is not performed.

Check sequence
Expected result
Result OK?
1.
Actuate the emergency stop
pushbutton.
The emergency stop pushbutton is eas‐
ily accessible.
When actuated, a safe stop 1 (SS1) is
initiated.
If an optional brake is in use, the brake
function will be activated once a stand‐
still has been reached.
Resetting the emergency stop device
does not trigger a restart.
All emergency stop pushbuttons within
the application have to be checked.

You must undo the manipulation on the safety system again after each individual test
sequence. Then you must reset the safety system and carry out a restart.
