12-4 Regular checkout and test
!WARNING
Make sure that following checkout and test routines are carried out on a regu-
lar base. Failure to test properly could result in serious injury to personnel.
All tests must be performed by qualified personnel. A copy of the checkout
results should be kept with the machine records.
!WARNING
Repeat Tests 1 and 2 on a daily base. Repeat Tests 1 to 6 at least every six
months. Failure to test properly could result in serious injury to personnel.
1. Guide the test object as shown in 12.3 through the entire protective field.
Check that
a) In automatic restart mode:
The outputs of the F3S-TGR-CL system remain in the OFF state dur-
ing the entire test.
b) In manual restart mode:
The beam blocked state is shown by the STATUS LED on the receiver
(LED off).
2. Activate the TEST/RESTART input (open the NC contact). Check that the
safety outputs of the F3S-TGR-CL system change from MACHINE RUN to
MACHINE STOP state.
3. Check that the mounting distance of the F3S-TGR-CL system is equal to
or greater than the minimum safe distance from the danger point. See the
chapter
Safe Mounting Distance
on page 17 for further information.
4. Determine that all access to the danger point not protected by the F3S-
TGR-CL system is guarded by other means, such as gates, fencing or oth-
er approved methods. Verify that all additional guarding devices are in-
stalled and operating properly.
5. Make sure the operator is not able to stand between the F3S-TGR-CL sys-
tem detection zone and the machine danger point. Verify that the light cur-
tain can only be reset from a position outside and within view of the
hazardous machine area. Otherwise please use the Pre-reset function.
6. Inspect the electrical connections between the guarded machine's control
system and the F3S-TGR-CL system. Verify that they are properly con-
nected to the machine such that a stop signal from the F3S-TGR-CL sys-
tem results in an immediate halt of the machine's cycle. See the chapter
Connection to the Machine control circuit
on page 26 for further informa-
tion.
