8. PERIODICAL CHECKS

The following is a list of recommended check and maintenance

operations that should be periodically carried-out by qualified

personnel (Paragraph 2.2.6 Controls after first installation”)

Check that:

The AOPD stays locked (

) during beam interruption along the

entire protected area, using the suitable “Test Piece” (*)

The AOPD 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 TEST

function is optional for the safety light curtains Type 4.

The response time upon machine STOP (including response time

of the AOPD and of the machine) is within the limits defined for the

calculation of the safety distance (see section 2 “Installation

mode”).

The safety distance between the dangerous areas and the AOPD

are in accordance with the instructions included in section 2

“Installation mode”.

Access of a person between AOPD 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 AOPD 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.

(*) according to the Fig.12 scheme

Verify that:
AOPD remains blocked (

) intercepting the beams along the

protected area using the specific test piece, following the Fig.12

scheme.
