Banner SC22-3E Safety Controller with Ethernet - Manual (Page 81)

• If the Safety Input is configured for auto reset: Verify that the delayed safety output turns OFF immediately for 500 ms,
then turns back ON.
23. Enabling Device Function
a. Verify that all inputs associated with the same output as the enabling device are in the Run state to turn the output(s) ON.
The enabling device is to remain in the Stop state. Verify that the associated Safety Outputs are ON.
b. Verify that when the enabling device is in the Run state: The associated Safety Outputs remain ON and the LCD displays
ENABLE MODE.
c. Verify that when the enabling device is in the Stop state: The associated Safety Outputs turn OFF.
d. Verify that when the enabling device is in the Run state:
a. The associated Safety Outputs turn ON.
b. The associated Safety Outputs turn OFF when the enabling device timer expires.
e. Verify that when the enabling device is in the Stop state and goes back into the Run state: The associated Safety Outputs
turn ON.
f. Verify that when all E-stop and rope-pull inputs associated with the same outputs are in the Stop state, one at a time (repeat
step for each device, as needed): The associated Safety Outputs turn OFF while in Enable mode.
g. Verify that the enabling device is in the Stop state and then apply a system reset.
a. Verify that the LCD no longer displays ENABLE MODE.
b. Verify that the Safety Controller is back to normal operation.
24. System (Final) Checkout
NOTE: 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 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.
a. Verify that all wiring complies with NEC and local wiring codes.
b. Apply power to the guarded machine and verify that the machine does not start up.
c. Apply power to the Safety Controller and apply resets as needed to turn the Safety Outputs ON.
d. Generate a stop command from each of the safety devices or safeguards connected to the input terminals of the Safety
Controller and verify for each input device that:
a. The Safety Outputs and Status Outputs operate as expected (e.g., ON-delays, OFF-delays, etc.). Use the configuration
summary to verify operation.
b. It is not possible for the guarded machine to be put into motion.
e. 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.
f. 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.
g. 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. (A Banner Applications Engineer 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.
