SC22-3 Safety Controller
Instruction Manual
System Checkout Procedures
7.1 Schedule of 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 . The checklist in section 7 .2 is generic and is
intended to assist in developing a customized (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
machine 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
manufacturers’ recommendation each day that the safeguarded
machine is in service .
*See Glossary for definitions .
7. System Checkout
Warning . . .
Periodic Checkouts
The commissioning, periodic and daily safety system
checks must be performed by appropriate personnel
at the appropriate times (as described at left) 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 SC22-3 Safety
Module and the guarded machine until the defect or problem has
been corrected (see Section 8) . 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.
