8.2.4 Diagnosing Output Malfunction
Proceed from the check of the output side to the check of the input side.
Check of output condition 1: Output indicator LEDs are on
Procedure 1
Check the wiring of the loads.
Procedure 2
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 in the output section. Please
contact your dealer.
Check of output condition 2: Output indicator LEDS are off
Procedure 1
Monitor the output condition using a programming tool.
•
If the output monitored is turned on, there is probably a duplicated output error.
Procedure 2
Forcing on the output using forcing input/output function.
•
If the output indicator LED is turned on, go to input condition check.
•
If the output indicator LED remains off, there is probably an abnormality in the output unit. Please
contact your dealer.
Check of input condition 1: Input indicator LEDs are off
Procedure 1
Check the wiring of the input devices.
Procedure 2
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 abnoramlity in the input unit.
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.
Check of input condition 2: Input indicator LEDs are on
Procedure
Monitor the input condition using a programming tool.
•
If the input monitored is off, there is probably an abnormality with the input unit. Please contact your
dealer.
•
If the input monitored is on, check the leakage current at the input devices (e.g., two-wire type sensor)
and check the program again.
Check
(1)Check for the duplicated use of output and for the output using the high-level instruction.
(2)Check the program flow when a control instruction such as MCR or JMP is used.
