9.1 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.
9.2 Daily Inspection and Maintenance of the Effectiveness of the Safety Device
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 for occupational health and safety and machine-specific directives apply to the perfor-
mance of daily tests.
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 diameter of the test rod must not be larger than the resolu-
tion selected for the equipment. Resolution must be determined in accordance with section 5.4.2.2 for the floating
blanking / auto floating blanking mode, and in accordance with section 5.4.4.3 for the reduced resolution mode.
The test rods for the full resolution and fix blanking modes must have a diameter of 14 mm (finger protection) and
30 mm (hand protection).
The safety field’s upper and lower limits are identified on the devices.
Each light beam between the emitter and the receiver must be inspected by obstruct-
ing each beam with the test rod. The test rod must be moved slowly through the safety
field in accordance with the adjacent diagram.
The red “OSSD OFF” indicator on the receiver must be continuously lit as long as the
safety field is penetrated.
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 ESPE, as well as all utilized accesso-
ries (connector cables, mounting kit), must be inspected for wear, damage, 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.
