CHAPTER 8

PERIODICAL CHECKS

The following is a list of recommended check and maintenance operations that should

be periodically carried-out by qualified personnel (see "

Controls after first installation" on

page 20

).

Check that:

• The ESPE remains in Safe State (Red OSSD LED ON) during beam interruption along 

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 dis

-

tance (see "

Installation" on page 6

).

• The safety distance between the dangerous areas and the ESPE are in accordance 

with the instructions included in "

Installation" on page 6

.

• 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.
