7 System Checkout
7.1 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 may result in serious bodily 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 98 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
6
). 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: Periodic Checkouts
The commissioning, periodic and daily safety system checks must be performed by appropriate
personnel at the appropriate times (as described in this manual) 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.
Commissioning Checkout: A Qualified Person
6
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
6
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
6
must also check the effectiveness of the protective devices 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 do so may result in serious bodily injury or death.
7.2 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.
7.2.1 Verifying System Operation
The commissioning checkout procedure must be performed by a Qualified Person
7
. It must be performed only
after configuring the Controller and after properly installing and configuring the safety systems and safeguarding
devices connected to its inputs (see
on page 71 and the appropriate standards).
The commissioning checkout procedure is performed on two occasions:
1. When the Controller is first installed, to ensure proper installation
