11.6 Diagnosing Output Malfunction
If the outputs do not function correctly, check the output side first and then the input side.
If the output indicator LEDs are ON:
•
Check the wiring of the loads.
•
Check if the power is properly supplied to the loads.
-
If the power is properly supplied to the load, there is probably an abnormality in
the load. Check the load again.
-
If the power is not supplied to the load, there is probably an abnormality with the
outputs. Please contact your dealer.
If the output indicator LEDs are OFF:
•
Monitor the output condition using FPWIN Pro.
-
If the output monitored is TRUE, there is probably a duplicate output error.
•
Set the output to TRUE by force using FPWIN Pro.
-
If the output indicator LED is turned ON, you must check the input side.
-
If the output indicator LED remains OFF, there is probably an abnormality with the
outputs. Please contact your dealer.
If the input indicator LEDs are OFF:
•
Check the wiring of the input devices.
•
Check that the power is properly supplied to the input terminals.
-
If the power is properly supplied to the input terminal, there is probably an
abnormality with the inputs. Please contact your dealer.
-
If the power is not supplied to the input terminal, there is probably an abnormality
in the input device or input power supply. Check the input device and input power
supply.
If the input indicator LEDs are ON:
Monitor the input condition using FPWIN Pro.
•
If the input monitored is FALSE, there is probably an abnormality with the inputs.
Please contact your dealer.
•
If the input monitored is TRUE, check the leakage current at the input devices (e.g.
two-wire type sensor) and check the program again, referring to the following:
-
Check for duplicate output errors and for outputs having been rewritten by high-
level instructions.
-
Check the program flow when instructions such as MC or JP are used.
