Operating instructions
Safety light barriers
EN
Operate the machine and check whether the hazardous movement
stops under the hereafter-mentioned circumstances.
1 Hazardous machine parts do not move when the protection field is
interrupted
2 The hazardous machine movement is immediately stopped, when
the protection field is interrupted with the test rod immediately before
the transmitter, immediately before the receiver and in the middle
between the transmitter and the receiver
3 No hazardous machine movement when the test rod is within the
protection field
4 The hazardous machine movement comes to standstill, when the
voltage supply of the AOPD is switched off
5.4 Half-yearly inspection
The following items must be checked every six months or when a
machine setting is changed
1 Machine stops or does not inhibit any safety function
2 No machine modification or connection change, which affects the
safety system, has taken place
3 The outputs of the AOPD are correctly connected to the machine
4 The total response time of the machine does not exceed the
response time calculated during the first putting into operation
5 The cables, the connectors, the caps and the mounting angles are in
perfect condition
5.5 Cleaning
If the optics cover of the sensors is extremely soiled, the OSSD outputs
can be disabled Clean with a clean, soft cloth with low pressure
The use of agressive, abrasive or scratching cleaning agents, which
could attack the surface, is prohibited
6. Diagnostic
Transmitters and receivers are equipped with an integrated signal lamp
in the transparent end cap The signal lamp indicates the operating
status or, in the event of a fault, a fault code
If there are no faults during operation, the status indicator
on the transmitter goes out after 10 minutes
6.1 Indication of configuration when system starts
The transmitters and receivers indicate the set beam coding once after
5 seconds when the system starts A number of short light impulses are
output in the process, which correlates with the number of the beam
coding
On the receiver, the indicator is delayed until there is no
change in the ON state or OFF state of the OSSDs for
5 seconds
Only SLB450 transmitter:
If the transmitter is configured for alternative range, an
additional light impulse is output for two seconds after the
beam coding has been indicated

6.3 Error indication
If there is a fault, red stays on and the fault number is indicated by way
of OFF impulses The number of impulses indicates the number of the
fault
Error
number
Cause
1
Wiring fault
2
Voltage fault in power supply
3
Voltage fault in safety output OSSD1 or OSSD2
4
Fault in heater regulation
(only SLB450 with integrated heater)
5
Incorrect configuration data
6
Internal fault during self-test and diagnosis
On the SLB450 with integrated heater, if the voltage is out of
range, a warning is issued by way of white light impulses at
a frequency of 1 Hz The warning goes out as soon as the
supply voltage is within the required range
7. Disassembly and disposal
7.1 Disassembly
The safety device must be disassembled in a de-energised condition
only
7.2 Disposal
The safety device must be disposed of in an appropriate manner in
accordance with the national prescriptions and legislations
