10 Inspection Instructions
The inspections described below serve to confirm compliance with specified safety requirements set forth in na-
tional/international regulations, in particular the safety requirements included in the machinery directive and the
directive concerning safety and health requirements for the use of work equipment (EC conformity).
The inspections also serve to detect influences which effect the device’s protective action, as well as any other un-
usual ambient influences.
10.1 Inspection Prior to Initial Start-Up
Inspection prior to initial start-up, conducted by trained personnel, is intended to assure that the electro-sensitive
protective equipment (ESPE), as well as any other safety components, have been correctly selected in accordance
with local ordinances, and that they provide the required protection when used for their intended purpose.
• Inspection of ESPE in accordance with local ordinances. Inspection for correct attachment of the safety device,
correct electrical connection to the controller and effectiveness in all of the machine’s operating modes.
• The same inspection requirements apply if the machine in question has been shut down for a lengthy period of
time and after significant modifications or repairs, if these may influence safety in any way.
• Observe regulations regarding the training of operating personnel by experts before operators begin work. The
company which operates the machine is responsible for training.
The safety function of the ESPE must be tested by penetrating the safety field with a suitable test rod with a diameter
of 30 mm prior to each time the machine is started up, and each time the machine has been retooled or set up. The
test object must be moved through the light beam. Each beam must be tested separately, and the OSSD/DIAG LED
display must switch from green to red. If restart inhibit is active, the green display must go out for each respective
obstructed channel (CH1/CH2).
The check list for initial operation (Chapter 13) helps executing the testing.
10.2 Daily Inspection and Maintenance
Regular inspections must be completed in accordance with local ordinances. They serve the purpose of detecting
changes to (e.g. over-travel time), or manipulation of the machine and the safety devices.
National regulations, e.g. ZH 1/597, ZH 1/281, and machine-specific directives apply to the execution of daily in-
spections.
Daily inspections must be conducted by a person who has been authorized and engaged to do so by the company
which operates the machine when work begins, and whenever a new shift is started.
• The effectiveness of the ESPE must be tested with supply power to the ESPE switched on, and supply power to
the hazardous motion of the machine switched off.
• Testing is conducted with the help of a suitable test rod, and never by manually reaching into the danger zone.
• The test object must be moved through the light beam. Each beam must be tested separately, and the OSSD/
DIAG LED display must switch from green to red.
10.3 Yearly Inspection and Maintenance
The effectivity of the Safety equipment has to be assured within the requested periods, minimum once a year. The
testing has to be executed by specialized personel.
• Minimum safety clearances and total response time should be checked. The inspector should also examine the
primary controls at the machine to assure that they function correctly, and that the safety output is switched in a
failsafe fashion.
• Furthermore, it must be determined whether or not it is only possible for persons and individual limbs to enter the
danger zone exclusively by passing through the safety field between the emitter and the receiver.
• The results of inspections and testing must be documented, and the user must keep a copy of such records on
file.
• The ESPE, as well as all utilized accessories (connector cables, mounting kit), must be inspected for wear, dam-
age, excessive contamination and correct mounting.
If any impairment of the device’s safety function is detected during daily testing or during operation, all work
at the respective machine must be immediately stopped.
