Test procedure log
The following test procedure must be performed by qualified personnel during
initial MS4800 system installation, according to the employer's regular inspec-
tion program and after any maintenance, adjustment or modification to the
MS4800 system or the guarded machine. Testing ensures that the light cur-
tain, safety system, and machine control system work together to properly
stop the machine. Failure to test properly could result in serious injury to per-
sonnel. To test the MS4800 system, use the correct size test object.
Machine identification_____________________________ Date___________
Item
Disable the guarded machine. Apply power to the
MS4800 system.
Visually inspect the machine to ensure that access to
the danger point is only through the MS4800 detec-
tion zone. If not, additional guarding, including
mechanical barriers ma be required. Verify that all
additional guarding devices and barriers are installed
and operating properly.
Verify that the mounting distance of the MS4800 sys-
tem is equal to or greater than the calculated mini-
mum safety distance from the danger point. See the
chapter "Safe mounting distance" for further informa-
tion. Ensure that the operator is not able to stand
between the MS4800 detection zone and the danger
point.
Check for signs of external damage to the MS4800
system, the machine and the electrical cables and
wiring. If damage is found, lock the machine off and
report to the supervisor.
Interrupt the MS4800 system detection zone with the
proper size test object. Move the test object inside
the perimeter (along the top, sides and bottom) of the
detection zone and up and down through the center.
At least one individual beam indicator must be lit
while the test object is anywhere in the detection
zone. If in automatic start mode, verify that the red
MACHINE STOP light is lit. If in start/restart INTER-
LOCK mode, verify that the red MACHINE STOP and
yellow INTERLOCK lights are on. Press and release
start button before proceeding to next step.
Start the machine. While the machine is in motion,
interrupt the detection zone with the test object. The
machine should stop immediately. Never insert the
test object into the dangerous parts of the machine.
With the machine at rest, interrupt the detection zone
with the test object. Verify that the machine will not
start with the test object in the detection zone.
Verify that the braking system is working properly. If
the machine does not stop fast enough, adjust the
braking system or increase the distance from the
detection zone to the danger point.
If the safety devices or the machine fails any of these
tests, do not fun the machine. Immediately tag or
LOCKOUT the machine to prevent its use and notify
the supervisor.
