Safety Instructions—Maintenance
For safety reasons, all inspection results are recorded.
Only persons, who clearly understand the functioning of the
GuardShield light curtain and of the machine, can conduct an
inspection.
If the installer, planning engineer, and operator are different people,
make sure that they have sufficient information available to conduct the
inspection.
Daily Inspection
Operate the machine and check, if the hazardous movement stops under
the following circumstances.
Figure 44 - Proper Testing of Protective Field Using Test Rod
Six-month Inspection
Check the following items every six months or whenever a machine
setting was changed.
Cleaning
If the optic front cover of the GuardShield light curtain is dirty, the
outputs of the GuardShield light curtain turn off. Take a clean, soft
cloth and rub without pressure. Do not apply aggressive, abrasive, or
gritty cleaning agents, which can attack the surface.
Date Code
Figure 45 - Product Label for Units Produced before 2017
• Serial number

don’t have the date printed on the label.
5.
The OSSD outputs are not connected to +24V DC.
6.
The connected switching elements (load) are not connected to 24V DC.
7.
No connection to a conventional power supply.
8.
If two or more GuardShield light curtain are to be used, make sure that each system is
properly installed, to avoid optical interference.
9.
Two seconds after switching on, the system starts to work properly, if the protective field is
free of obstructions.
ATTENTION:
Never operate the GuardShield light curtain before
conducting the following inspection. Improper inspection can lead
to serious or even deadly injury.
1.
Approach to hazardous machine parts must only be possible through passage through the
protective field of GuardShield light curtain.
2.
Operators cannot step through the sensing area while working on dangerous machine
parts.
3.
The safety distance of the application is bigger than the calculated value.
4.
The optic front cover is not scratched or dirty.
5.
The protective field is interrupted.
6.
The hazardous movement stops immediately if you interrupt the protective field by placing
the test rod directly:
• In front of the transmitter
• In front of the receiver
• In between the transmitter and receiver
7.
No hazardous machine movement while the test rod is anywhere within the protective
field.
8.
The power supply of the GuardShield light curtain is turned off.
9.
If the blanking function is activated, check all sections of the protective field with the
appropriate test rod (see
).
IMPORTANT
If any of the conditions previously described do not result in
the hazardous motion of the machine stopping, do not allow
the protected machine to be placed in operation.
1.
Machine stops or does not obstruct any safety function.
2.
The latest machine or connection modifications have no effect on the control system.
3.
The outputs of the GuardShield light curtain are properly connected to the machine.
4.
The total response time of the machine is shorter than the calculated value.
5.
Cables and plugs of the GuardShield light curtain are in flawless condition.
6.
Mounting brackets, caps and cables are tightly secured.
