Instruction Manual
Periodic Checkout Procedures
6.3 Daily Checkout
Perform this checkout procedure at every shift change, power-
up and machine set-up change. During continuous machine
run periods, this checkout must be performed at intervals not to
exceed 24 hours. A Designated Person or Qualified Person (as
defined in Section 1.18) must perform the procedure; checkout
results should be recorded and kept on or near the guarded
machine, per OSHA 1910.217(e)(1).
1. Verify that access to the guarded area is not possible from
any area not protected by the safeguards interfaced with
the safety system that includes the MMD-TA-1..B module.
Hard guarding, or supplemental presence-sensing devices
must be installed, wherever needed, to prevent any person
from reaching around the light grid or entering into the
hazard area. Verify that all supplemental guarding devices
and hard guarding are in place and operating properly.
2. Verify that the safeguards interfaced with
the safety system
that includes the MMD-TA-1..B module have been properly
installed and maintained. See relevant instruction manuals
or data sheets.
3. Verify that it is not possible for a person to access the
hazard(s), undetected by the safeguards interfaced with the
safety system that includes the MMD-TA-1..B module or by
other supplemental guarding (as described in appropriate
standards).
4. Verify that the Reset switch is mounted outside the guarded
area, out of reach of anyone inside the guarded area, and
that the key or other means of preventing inadvertent use is
in place.
5. Verify the system(s) checkout procedures for the external
safety systems connected to the MSSI and the SSI inputs
as described by the appropriate manuals.
6. Initiate machine motion of the guarded machine and, during
the cycle, generate a stop command from the safeguarding
device. Do not attempt to insert anything into the dangerous
parts of the machine. Upon issuing the stop command,
the dangerous parts of the machine should come to a stop
with no apparent delay. Upon reset of the safeguard and
the Module, verify that the machine does not automatically
restart, and that the initiation devices must be engaged to
restart the machine.
7. With the guarded machine at rest, generate a stop
command from the safeguarding device(s) and verify that
it is not possible for the guarded machine to be put into
motion.
8. Check carefully for external signs of damage or changes to
the safety system that includes the MMD-TA-1..B module,
the interfaced safeguards, the guarded machine, and their
electrical wiring. Any damage or changes found should be
immediately reported to management.
If any of these checks fail, do not attempt to use the safety
system that includes the MMD-TA-1..B module until the
reason for the failure(s) is identified and corrected.
6.4 Semi-Annual Checkout
Perform this checkout procedure every six months following
the safety system that includes the MMD-TA-1..B module
installation. A Qualified Person (as defined in Section 1.18) must
perform the procedure; checkout results should be recorded and
kept on or near the guarded machine, per OSHA 1910.217(e)(1).
1. Perform the commissioning checkout procedure (Section
6.2) If any decrease in machine braking ability has
occurred, make the necessary clutch/brake repairs, readjust
safeguard separation distance (Ds) appropriately, record
the new Ds calculation, and re-perform the Daily Checkout
procedure.
2. Examine and test the machine primary control elements
(MPCEs) and any intermediary controls (such as interface
modules) to verify that they are functioning correctly and
are not in need of maintenance or replacement.
3. Inspect the guarded machine to verify that no other
mechanical or structural problems could prevent the
machine from stopping or assuming an otherwise safe
condition when signalled to do so by the safety system that
includes the MMD-TA-1..B module.
4. Examine and inspect the machine controls and connections
to the safety system that includes the MMD-TA-1..B module
to verify that no modifications have been made which
adversely affect the System.
If any of these checks fail, do not attempt to use the safety
system that includes the MMD-TA-1..B module until the
reason for the failure(s) is identified and corrected.
