8 System Checkout
8.1 Schedule of Required Checkouts
Verifying the configuration and proper functioning of the Safety Controller includes the verification of each safety and non-safety input
device, along with each output device. As the inputs are individually switched from the Run state to the Stop state, the Safety Outputs
must be checked to verify that they turn ON and OFF as expected.
A comprehensive test must be used to verify the operation of the Safety Controller and the functionality of the intended configuration.
Section
8.3 Initial Setup, Commissioning and Periodic Checkout on page 76 is generic and is intended to assist in developing a custom-
ized (configuration-specific) checklist for each application. This customized checklist must be made available to maintenance personnel
for commissioning and periodic checkouts. A similar, simplified daily checkout checklist should be made for the operator (or Designated
Person). It is highly recommended to have copies of the wiring and logic diagrams and the configuration summary available to assist in
the checkout procedures.
Commissioning Checkout: A Qualified Person* must perform a safety system commissioning procedure before the safeguarded ma-
chine application is placed into service and after each Safety Controller configuration is created or modified.
Periodic (Semi-Annual) Checkout: A Qualified Person* must also perform a safety system re-commissioning semi-annually (every 6
months) or at periodic intervals based on the appropriate local or national regulations.
Daily Operational Checks: A Designated Person* must also check the effectiveness of the protective devices per the device manufac-
turers’ recommendation each day that the safeguarded machine is in service.
*See section 12 Glossary on page 128 for definitions.
WARNING: . . . Periodic Checkouts
The commissioning, periodic and daily safety system checks must be performed by appropriate personnel at the appropriate
times (as described above) in order to ensure that the safety system is operating as intended. Failure to perform these
checks may create a potentially dangerous situation which could lead to serious injury or death.
WARNING: . . . Do Not Use Machine Until System Is Working Properly
If all of these checks cannot be verified, do not attempt to use the safety system that includes the Safety Controller and
the guarded machine until the defect or problem has been corrected (see Troubleshooting). Attempts to use the guarded
machine under such conditions could result in serious bodily injury or death.
WARNING: . . . Before Applying Power to the Machine
Verify that the guarded area is clear of personnel and unwanted materials (such as tools) before applying power to
the guarded machine. Failure to do so could result in serious bodily injury or death.
8.2 Commissioning Checkout Procedure
Before proceeding, verify that:
• The Safety Output terminal strip is NOT connected to the Safety Controller; unplug the 7-pin connector so that the Safety Outputs
SO1 (A and B), SO2 (A and B) and SO3 (A and B) are not connected to the machine), and
• Power has been removed from the machine, and no power is available to the machine controls or actuators.
Permanent connections will be made at a later point in this checkout.
