Check the alarm code on the teaching tool such as PC software.

(8) Check the connectors for disconnection or connection error.

Before performing a continuity check, turn off the power (to prevent electric shocks) and

disconnect the cables of measuring instruments (to prevent accidental power connection

due to sneak current path).

(10) Check the I/O signals.

Using the host controller (PLC, etc.) or a teaching tool such as PC software, check the

presence of inconsistency in I/O signal conditions.

(11) Check the noise elimination measures (grounding, installation of surge killer, etc.).
