SC22-3 Safety Controller
Instruction Manual
System Checkout Procedures
20 .
□
System (Final) Checkout
DO NOT continue checkout until all problems are corrected.
The operation of the Safety Controller with the guarded machine must now be verified before the combined system may be put into
service . To do this, a Qualified Person must perform the following checks .
Remove power from the Safety Controller .
Reinstall the Safety Output terminal strip to the SC22-3 Safety Controller to connect the machine control circuit to the safety
outputs SO1 (A and B), SO2 (A and B), and SO3 (A and B) . This is a permanent connection.
□
Verify that all wiring complies with NEC and local wiring codes .
□
Apply power to the guarded machine and verify that the machine does not start up .
□
Apply power to the Safety Controller and apply resets as needed to turn the safety outputs ON .
□
Generate a stop command from each of safety devices or safeguards connected to the input terminals of the Safety Controller
and verify for each input device that:
□
The safety outputs and status outputs operate as expected (e .g ., ON-delays, OFF-delays, etc .) . Use the configuration
summary to verify operation .
□
It is not possible for the guarded machine to be put into motion .
□
Initiate machine motion of the guarded machine and, while it is moving, generate a stop command from each of the safety
devices or safeguards . Do not attempt to insert anything into the dangerous parts of the machine . Upon issuing the stop
command, verify that the dangerous parts of the machine come to a stop .
□
Upon reset of the safety device or safeguard and/or the Controller, verify that the machine does not automatically restart, and
that the initiation devices must be engaged to restart the machine
□
Test the machine stopping response time, using an instrument designed for that purpose, to verify that it is the same or less
than the overall system response time specified by the machine manufacturer . (Banner’s Applications Engineering Department
may be able to recommend a suitable instrument .)
If any of these checks fail, do not attempt to use the system until the reason for the failure(s) is identified and
corrected.
