5.2.5.5 Reduced resolution
• This function reduces the resolution of the ESPE electronically.
• This allows for the selection of an object size, as of which the safety output should be switched.
• Obstructions (chips, cables) which could interrupt the safety field therefore do not cause a switch-off or
interrupt the process unnecessarily.
NOTE!
• Objects in the safety field are not monitored for presence or quantity (no “monitored
blanking”). This means that sufficiently small objects can be removed from the safety field
and brought in again at any point without the ESPE classing this as a penetration.
• Reduced muting can not be combined with partial muting or Full Muting Enable.
• The ESPE should be tested for effective resolution using a test rod.
• Reduced resolution can be taught-in on the receiver of the ESPE or parametrized via
IO-Link.
5.2.5.5.1 Effective Resolution for Calculating the Safety Clearance
DANGER!
• The function changes the resolution of the ESPE. The effective resolution is relevant for the
safety clearance.
• The safety clearance must be re-calculated when using the reduced resolution.
• For resolutions > 40 mm, the safety clearance must be calculated with the margin CRT =
850 mm! (For details on the calculation, see
• When calculating the safety clearance for reduced resolution, the response time “special
setting” must be used (see
Section “4.2 Response times” on page 17)
