8. PERIODICAL
CHECKS
The following is a list of recommended check and maintenance operations that should be periodically
carried out by qualified personnel.
Check that:
The ESPE stays locked (
) during beam interruption along the entire protected area, using the
suitable “Test Piece”. (*)
The ESPE is correctly aligned. Gently press onto product side in both directions. The red LED
should remain OFF
.
Enabling the TEST function, the OSSD outputs should open (the red LED
is ON and the
controlled machine stops).
The response time upon machine STOP (including response time of the ESPE and of the machine)
is within the limits defined for the calculation of the safety distance (see chapter 2 “
Installation
mode
”).
The safety distance between the dangerous areas and the ESPE are in accordance with the
instructions included in chapter 2 “
Installation mode
”.
Access of a person between ESPE and machine dangerous parts is not possible nor is it possible
for him/her to stay there.
Access to the dangerous area of the machine from any unprotected area is not possible.
The ESPE and the external electrical connections are not damaged.
The frequency of checks depends on the particular application and on the operating conditions of the
safety light curtain.
