9 PERIODICAL MAINTENANCE AND WARRANTY
The following is a list of recommended check and maintenance operations that should be periodically
carried-out by qualified personnel (see also paragraph 3.2.6
– “Controls after first installation”)
Check that:
•
The ESPE stays in SAFE state ( ) during beam interruption along the entire protected
area, using the specific Test Piece (TP-40, TP-50. TP-90), according to the Figure 21
scheme.
•
The ESPE is correctly aligned. Press slightly product side, in both directions and the red
LED ( ) must not turn ON.
•
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 section 3
– “INSTALLATION MODE”).
•
The safety distance between the dangerous areas and the ESPE are in accordance with
the instructions included in section 3
– “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.
