Care and Maintenance
The SafeShield safety light curtain is maintenance-free. The front

screen(s) (see “Additional Front Screen (Weld Spark Guard)” on
page 45) should be cleaned at regular intervals and when dirty.
➢ Do not use aggressive cleaning agents.
➢ Do not use abrasive cleaning agents.
Note Static charges cause dust particles to be attracted to the
front screen. You can prevent this effect by using the
antistatic plastic cleaner.
How to clean the front screen and/or the additional front
screen (optional extra):
➢ Use a clean and soft brush to remove dust from the front
screen.
➢ Then wipe the front screen with a clean and damp cloth.
Note
➢ After cleaning, check the position of sender and receiver to
make sure that the protective device cannot be bypassed
(reaching above, below or behind).
➢ Verify the effectiveness of the protective device as described in
“Test Notes” on page 31.
Fault Diagnosis
This section describes how to identify and remedy errors and
malfunctions during the operation of the safety light curtain.
Recommendation
You can speed up the fault diagnostics of some frequent faults by
querying a signal on the signal output on the safety light curtain on
the occurrence of the fault. Details can be found in “Signal Output
(ADO)” on page 12.
What To Do in Case of Faults
ATTENTION: Cease operation if the
cause of the malfunction has not been
clearly identified!
Stop the machine if you cannot clearly
identify or allocate the error and if you
cannot safely remedy the malfunction.
