9 PERIODICAL CHECKS
The following is a list of recommended check and maintenance operations that should be periodically carried-out
by qualified personnel (cfr.
Controls after first installation page 24
Check that:
The ESPE stays in SAFE state during beam interruption along the entire protected area, using the specific Test
Piece (TP-14 or TP-30)
The ESPE is correctly aligned. Press slightly product side, in both directions and the red LED (named OSSD
on RX side) must not turn ON.
Enabling the TEST function (on TX side), the OSSD outputs should open (the red LED, OSSD on RX side, 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
INSTALLATION page 17
The safety distance between the dangerous areas and the ESPE are in accordance with the instructions
included in chapter
INSTALLATION page 17
Access of a person between ESPE and machine dangerous parts is not possible nor it is 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.
