SECTION 13
Checkout and test procedure
13-1 Checkout Procedure
Once the MS4800 system has been configured, mounted, aligned and prop-
erly connected to the machine control system, the initial Checkout Procedure
detailed in Appendix A must be performed by qualified personnel. A copy of
the checkout results should be kept with the machine records.
13-2 Test Procedure
!WARNING
The tests outlined in the Test Procedure in Appendix B must be performed at
installation, according to the employer's regular inspection program and after
any maintenance, tooling change set up, adjustment or modification to the
MS4800 system or the guarded machine. Where a guarded machine is used
by multiple operators or shifts, it is suggested that the test procedure be per-
formed at each shift or operator change. Testing ensures that the light curtain
and the machine control system work properly to stop the machine. Failure to
test properly could result in serious injury to personnel.
The test procedure must be performed by qualified personnel. To test the
MS4800 system with fixed blanking and floating blanking disabled, use the
OMRON STI supplied test object. For applications where fixed blanking or
floating blanking is enabled, see Table in chapter
5-3-1 The effect of Fixed or
Floating Blanking on minimum object resolution to determine the proper size
of the test object.
When using a MS4800 system set for Automatic Start Mode operation, in con-
junction with an OMRON safety relay module, it is necessary to verify that the
outputs of the safety relay unit can properly change state by causing an inten-
tional beam break at least every change of shift or 24 hours of operation.
13-3 Using the test object
When using the test object, guide it through
the detection zone as shown:
