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 4700 system or the guarded machine. Where a guarded machine is used by
multiple operators or shifts, it is suggested that the test procedure be performed at each shift or operation
change. For any and all installations, OSTI recommends the Test Procedure in Appendix B be performed at
least once a year. 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 4700 system without Exact
Channel Select and Floating Blanking disabled, use the STI-supplied test object. For applications
where Exact Channel Select or Floating Blanking are enabled, see
and
to determine the proper size test object.
When using a 4700 system for Automatic Start Mode operation, in conjunction with an RM-1 relay
module, it is necessary to verify that the RM-1 outputs can properly change state by causing an
intentional beam break at least every change of shift or 24 hours of operation.
