7 System Checkout7.1 Schedule of Required CheckoutsVerifying the configuration and proper functioning of the Safety Controller includes checking each safety and non-safetyinput 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 ProperlyIf all of these checks cannot be verified, do not attempt to use the safety system that includesthe Banner device and the guarded machine until the defect or problem has been corrected. Attemptsto use the guarded machine under such conditions may result in serious bodily injury ordeath.A comprehensive test must be used to verify the operation of the Safety Controller and the functionality of the intendedconfiguration. Initial Setup, Commissioning and Periodic Checkout Procedures on page 98 is intended to assist indeveloping a customized (configuration-specific) checklist for each application. This customized checklist must be madeavailable to maintenance personnel for commissioning and periodic checkouts. A similar, simplified daily checkout checklistshould be made for the operator (or Designated Person6). It is highly recommended to have copies of the wiring and logicdiagrams and the configuration summary available to assist in the checkout procedures.WARNING: Periodic CheckoutsThe commissioning, periodic and daily safety system checks must be performed by appropriatepersonnel at the appropriate times (as described in this manual) in order to ensure that the safetysystem is operating as intended. Failure to perform these checks may create a potentiallydangerous situation which could lead to serious injury or death.Commissioning Checkout: A Qualified Person6 must perform a safety system commissioning procedure before thesafeguarded machine application is placed into service and after each Safety Controller configuration is created ormodified.Periodic (Semi-Annual) Checkout: A Qualified Person6 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 Person6 must also check the effectiveness of the protective devices per thedevice manufacturers’ recommendation each day that the safeguarded machine is in service.WARNING: Before Applying Power to the MachineVerify that the guarded area is clear of personnel and unwanted materials (such as tools) beforeapplying power to the guarded machine. Failure to do so may result in serious bodily injury or death.7.2 Commissioning Checkout ProcedureBefore proceeding, verify that:• All solid state and relay output terminals of the complete Safety Controller system are not connected to themachine. 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 actuatorsPermanent connections are made at a later point.7.2.1 Verifying System OperationThe commissioning checkout procedure must be performed by a Qualified Person7. It must be performed onlyafter configuring the Controller and after properly installing and configuring the safety systems and safeguardingdevices connected to its inputs (see Safety Input Device Function 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 installation6 See Glossary on page 115 for definitions.7 See Glossary on page 115 for definitions.XS/SC26-2 Safety Controller97
