Procedure
1. Installation has been carried out correctly (see
).
2. Alignment takes place with a free safety field while monitoring the LEDs and segment display.
3. Loosen the mounting so that the ESPE can only just be moved.
4. Align the emitter and receiver until the highest possible signal strength is shown.
5. Tighten the mounting so that the ESPE can no longer be adjusted. The tightening torques for the different
mounting components must be observed.
NOTE!
wenglor offers a suitable laser alignment tool Z98G001 to make a reliable alignment easier
even with large distances (see
10.4 Checking for Initial Start-up
• The described tests are intended to confirm compliance with national / international safety regulations.
NOTE!
• Regulations governing operator induction by specialist personnel must be observed
before work is commenced.
• The company which operates the machine is responsible for training.
• A test body with 14 or 30 mm depending on the resolution of the ESPE must be used for
initial start-up. For applications with reduced resolution, test bodies with 24 or 34 mm can
also be used for initial start-up. (see EN 61496-1, Para. 7f)
• First of all, a check must be carried out to determine whether the ESPE has been chosen correctly accord-
ing to the local regulations and whether it offers the necessary protection when used as intended.
• The effectiveness of the ESPE in all operating modes available on the machine must then be checked.
• The check takes place according to the checklist for initial start-up (see
The check must be carried out in the following cases:
• Before the initial start-up,
• After changes have been made on the machine,
• After extended machine downtimes,
• Following modifications or repairs on the machine.
DANGER!
• It is important to ensure that no one is endangered during initial start-up of the machine.
There must be no persons located in the danger zone.
• Work on the machine must be immediately stopped if any impairment of the safety func-
tion is detected. Once the situation has been resolved, the effectiveness of the ESPE must
be checked again according to the checklist (see
