6   TROUBLESHOOTING

6.2 Using the LED Indications to Check Errors

This section explains how to check errors using the LED indications of the AJ65SBT-

62DA.

Refer to the PLC CPU and master module user's manual for issues regarding the PLC

CPU and master module.

(1)   When the AJ65SBT-62DA "PW" LED is off

Check Item

Corrective Action

Is 24VDC power on?

Check the external power supply.

Is the voltage of the 24VDC power supply within the

specified value?

Set the voltage value to within the range 20.4 to

26.4V.

(2)   When the AJ65SBT-62DA "RUN" LED flickers

Check item

Corrective action

Is the LED flickering at 0.1s intervals in the normal

mode?

1. Using the error code (RWrn+2), check the

channel at which the output range setting error

has occurred.

2. Make correction to the sequence program or GX

Developer setting.

Is the LED flickering at 0.5s intervals in the normal

mode?

1. Using the error code (RWrn+2), check the

channel at which the digital value setting error

has occurred.

2. Check the check code (RWrn, RWrn+1) of the

channel at which the error has occurred.

3. Make correction to the sequence program.

Is the LED flickering at 0.1s intervals in the test

mode?

Set all channels to any of "user range settings 1 to

3" in output range setting.

Is the LED flickering at 0.5s intervals in the test

mode?

Change the offset/gain adjustment to within the

available setting range.

(3)   When the AJ65SBT-62DA "RUN" LED is off

Check item

Corrective action

Has the watchdog timer error occurred?

Using the link special registers (SW0084 to

SW0087) of the master module, check the

watchdog timer error and power on the AJ65SBT-

62DA again.

If the "RUN" LED is not lit after power is switched

on again, the possible cause is a hardware fault.

Contact your nearest Mitsubishi representative.

Has the TEST terminals (across 8-9) been shorted

to enter the test mode?

After making offset/gain adjustment, open the TEST

terminals (across 8-9).

(4)   When the AJ65SBT-62DA "L RUN" LED is off

Communications are broken.

For details, refer to troubleshooting in the user's manual of the master module

used.
