Periodic Checkout and Maintenance
WARNING: Do Not Use System Until Checkouts Are Verified
If all of the described checks cannot be verified, do not attempt to use the two-hand control safety
system until the defect or problem has been corrected. Attempts to use the guarded machine un-
der such conditions could result in serious bodily injury or death.
Daily Checkout
To be Performed at every Power-up, Shift Change, and Machine Setup Change:
Daily checkout and checkouts after tooling and machine setup changes must be performed by a Designated Person, appointed and iden-
tified in writing by the employer.
1. Verify that all point-of-operation guards are in place and operating properly.
2. Verify that the two actuating devices must be simultaneously engaged to actuate the machine.
3. For single-cycle machines: Verify that maintained engagement of the two actuating devices results in only one machine cycle.
4. For part-revolution clutch machinery: Verify that release of either actuating device results in the immediate arrest of the machine
motion.
5. Verify that the Mute indicator comes ON during the non-hazardous portion of the machine cycle and that the muting function occurs
only when exposure to the safeguarded hazard is not possible.
6. Verify that release of the hand controls is possible during the mute cycle and that the machine cycle is not stopped.
7. Verify that the machine cycle stops any time the mute cycle ends or when the SSI input opens.
8. Verify that the distance from each actuating device to the closest hazard point is not less than the calculated safety distance (see
on page 9).
Semi-Annual Checkout
To be Performed at Six-Month Intervals:
This semi-annual checkout must be performed by a Qualified Person.* A copy of test results should be kept on or near the machine.
1. Perform the daily checkout procedure (see above).
2. Perform the initial checkout procedure (see
3. Calculate the separation distance (see
on page 9), and verify that the actuating devices are far enough away
from the nearest hazard point. Relocate the actuating devices, if necessary.
4. Verify that the actuating devices are positioned to require the use of both hands for operation, and are protected from false or
inadvertent operation.
5. Inspect the machine controls and the connections to the DUO-TOUCH SG Safety Module to ensure that wiring is correct, as descri-
on page 10, and that no modifications have been made which could adversely affect the System.
* Qualified Person: A person who, by possession of a recognized degree or certificate of professional training, or who, by extensive
knowledge, training, and experience, has successfully demonstrated the ability to solve problems relating to the installation, maintenance
and use of the DUO-TOUCH SG Two-Hand Control Safety System.
