GSR Hinge Switch Safety Function Verification and Validation Checklist (continued)
Abnormal Operation Validation
The safety relay system properly responds to all foreseeable faults with corresponding
diagnostics.
Hinge Switch Input Tests
Test Step Validation Pass/Fail Changes/Modification
While the system is running, remove the channel 1 wire
from the safety relay. Both contactors de-energize. Verify
proper machine-status indication and safety-relay status
indication. Repeat for channel 2.
While the system is running, short channel 1 of the safety
relay to 24V DC. Both contactors de-energize. Verify proper
machine-status indication and safety-relay status indication.
Repeat for channel 2.
While the system is running, short channel 1 of the safety
relay to 0V DC. Both contactors de-energize. Verify proper
machine-status indication and safety-relay status indication.
Repeat for channel 2.
While the system is running, short channels 1 and 2 of the
safety relay. Both contactors de-energize. Verify proper
machine-status indication and safety-relay status indication.
GSR Logic Solver Tests
Test Step Verification and Validation Pass/Fail Changes/Modification
While the system is running, remove the single wire safety
connection between two adjoining safety relays in the
system. All contactors de-energize. Verify proper
machine-status indication and safety-relay status indication.
Repeat for all safety connections.
While the system is running, turn the logic rotary switch on
the safety relay. All contactors remain energized. Verify
proper machine-status indication and safety-relay status
indication. Repeat for all safety relays in the system.
Safety Contactor Output Tests
Test Step Verification and Validation Pass/Fail Changes/Modification
While the system is running, remove the contactor feedback
from the safety relay. All contactors remain energized.
Initiate a Stop command followed by a Reset command.
The relay does not restart or reset. Verify proper
machine-status indication and safety-relay status indication.
