Not until proper function of the optoelectronic safety device is ascertained may it be
integrated in the control circuit of the system.
Notice!
As a safety inspection, Leuze electronic offers testing by a competent person prior to the
initial start-up .
8.1.1
Checklist - before the initial start-up
Tester: competent person
This checklist serves as a reference for the machine manufacturer or supplier. It replaces
neither testing of the complete machine or system prior to the initial start-up nor their
periodic testing by a competent person. This checklist contains minimum testing
requirements. Depending on the application, other tests may be necessary.
• Store this checklist with the machine documents.
Check:
Yes
No
Were all safety directives and standards relevant to this machine
type observed?
Does the Declaration of Conformity of the machine include a listing
of these documents?
Does the safety sensor satisfy the safety-related capability (PL, SIL,
category) as required by the risk assessment?
Circuit diagram: Are both safety-related switching outputs (OSSDs)
integrated in the downstream machine control acc. To the required
safety category?
Circuit diagram: Are the switching elements (e.g. contactors) with
positive-guided contacts that are controlled by the safety sensor
monitored by a feedback circuit (EDM)?
Does the electrical wiring match the circuit diagrams?
Have the required protective measures against electrical shock
been effectively implemented?
Has the maximum stopping time of the machine been remeasured
and recorded in the machine documents?
Is the required safety distance (protective field of the safety sensor
to the next point of operation) maintained?
Are all points of operation of the machine accessible only through
the protective field of the safety sensor? Are all additional protective
devices (e.g. safety guards) correctly mounted and protected
against tampering?
Is the command device for triggering the start/restart interlock of the
safety sensor or the machine mounted in accordance with specifi-
cations?
Is the safety sensor correctly aligned and are all fastening screws
and plugs secure?
