10.3 Unit Test
Run a unit test to check if there is any hardware failure in the safety remote I/O module.
1. Power off the module power supply.
2. Connect the PORT1 and PORT2 connectors of the
safety remote I/O module with an Ethernet cable.
3. Set the station number setting switch as follows.
• 10: TEST
• 1: 0
4. Power on the module power supply.
5. Unit test begins.
The MODE LED flashes while the unit test is being executed.
6. The MODE LED turns off when the unit test is
completed.
• When the test is completed successfully: The ERR. LED
does not turn on, but remains off.
• When the test is completed with an error: The ERR. LED
turns on.
If the test fails, replace the Ethernet cable and run the test
again. If the test fails again, it may be due to a hardware
failure in the safety remote I/O module. Please consult your
