11 System Checkout
11.1 Schedule of Required Checkouts
Verifying the configuration and proper functioning of the Safety Controller includes checking 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 validated that they turn On and Off as expected.
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 Banner
device and the guarded machine until the defect or problem has been corrected. Attempts to use the
guarded machine under such conditions could result in serious injury or death.
A comprehensive test must be used to verify the operation of the Safety Controller and the functionality of the intended
configuration.
Initial Setup, Commissioning, and Periodic Checkout Procedures
on page 126 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
9
). It is highly recommended to have copies of the wiring and logic
diagrams and the configuration summary available to assist in the checkout procedures.
WARNING:
• Perform Periodic Checkouts
• Failure to perform these checks could create a dangerous situation that could result in serious
injury or death.
• The appropriate personnel must perform the commissioning, periodic, and daily safety system
checks at the suggested times to ensure that the safety system is operating as intended.
Commissioning Checkout: A Qualified Person
9
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
9
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
9
must also check the effectiveness of the risk reduction measures, per the
device manufacturers' recommendation, each day that the safeguarded machine is in service.
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 follow these instructions could result in serious injury or death.
11.2 Commissioning Checkout Procedure
Before proceeding, verify that:
• All solid state and relay output terminals of the complete Safety Controller system are not connected to the
machine. Disconnecting all of the Safety Controller's safety output plug-on terminals is recommended.
• Power has been removed from the machine, and no power is available to the machine controls or actuators
Permanent connections are made at a later point.
11.2.1 Verifying System Operation
The commissioning checkout procedure must be performed by a Qualified Person
10
. It must be performed only after
configuring the Safety Controller and after properly installing and configuring the safety systems and safeguarding devices
connected to its inputs (see
on page 29 and the appropriate standards).
The commissioning checkout procedure is performed on two occasions:
