Troubleshooting Flow

If the operating display does not appear after turning on the controller’s power, follow the
measures in the procedure below.

If a problem appears complicated, contact our sales representative.

Ask the vendor for repair.

Find the cause.

Totally

inoperable?

Yes

Is key

operation

faulty?

Yes

Check wiring on the
power supply
terminals.

Check the key lock
setting.

Is display

faulty?

Yes

Turn off power, and
then turn it on
again.

Is I/O

signal faulty?

Yes

Check the
instrument’s I/O
specifications.

Check the supply
voltage.

Check the specifications
of I/O counterpart for
wrong polarity.

Check the
communication-related
parameters.

Check the specifications
of communication
counterpart.

Check
communication wiring.

communication

link faulty?

Does the code

include a communication

option?

Yes

Normal?

key lock

enabled?

Check the
instrument's suffix
code.

Yes

Correct?

Correct the

error(s).

Disable

key lock.

No communication

capability.

Is the instrument

defective?

IMPORTANT

Take note of the parameter settings when asking the vendor for repair.
