2.9.9 Rotating the display by 180 degrees
The orientation of the 7 segment display can be rotated by 180 degrees
via the software option This ensures that the display remains readable
in rotated mounting position of the AOPD

2.10 Self-test
The system performs a complete self-test and safety test within 2
seconds after the operating voltage has been switched on If the
protection field is free, the system switches to the ON condition
(automatic mode) In case of an error, the outputs at the receiver do not
switch to the ON state An error message is emitted in the form of an
error code For more information, refer to chapter Fault diagnosis
During operation, the system executes a cyclic self-test Safety-
relevant faults are detected within the reaction time and cause the
outputs to be switched off and an error code to be emitted
2.11 Beam coding A
The preset beam coding of the safety light curtain must be adjusted,
when systems operating in each other's vicinity and a set-up as shown
in the image below (no interference) is impossible When supplied, the
beam coding A is
not active
A receiver with activated beam coding A
can distinguish the beams of the emitter with the same beam coding,
which are destined to this particular receiver, from foreign beams
If adjacent systems are operated without beam coding A, the user is at
risk

No interference
Interference:
beam coding A required!
• The beam coding A avoids mutual interference of adjacent systems
• The beam coding A is permanently shown by the emitter and the
receiver by means of flashing LED's (refer to LED status information)
• The beam coding A must be set for
each sensor
(receiver and emitter)
individually
• The function at the receiver is activated in parameter setting mode (P 6)

The response time of the system is increased when beam
coding A is used To this end, the safety distance must be
adjusted Refer to chapter: Response time
2.12 Bluetooth
Download the Schmersal app SLC Assist from your app store to your
smartphone or tablet The app is available for both, iOS and Android
devices Activate Bluetooth and location services on your smartphone
or tablet
Parameter
P8
can be used to deactivate the Bluetooth function (see
Parameterisation chapter) In the as-delivered condition, the BLE
function is active This is signalled by a blue pulse on the receiver
during system start-up
3. Parameterisation
The parameter setting of the SLC/SLG440 enables the individual
adjustment of the desired functionality to the application
Parameter display (7-segment display)
A = parameter active
- = parameter not active
S.
= save the current configuration
C.
= delete the current configuration, new configuration = factory setting
n = unavailable (unauthorised setting, refer to Parameter setting
information)
d.
= diagnostic/setting mode
Parameter selection
Selection, change and acceptance of the parameters by means of the
command device pushbutton S1:
- Switch to parameter setting Px briefly press the button
01 … 15 sec
- Change parameter setting Px
press button 25 … 6 sec
- Save

Procedure
1) For the parameter setting, the receiver must be isolated from the
operating voltage In de-energised condition, the following jumper
connection and the pushbutton S1 must be connected
