H Troubleshooting
The following table can be used for troubleshooting when Relay
operation is not normal. Refer to this table when checking the circuit
and other items. If checking the circuit reveals no abnormality, and it
appears that the fault is caused by a Relay, contact your OMRON
representative. (Do not disassemble the Relay. Doing so will make it
impossible to identify the cause of the problem.)
A Relay is composed of various mechanical parts, including a coil,
contacts, and iron core. Among these, problems occur most often
with the contacts, and next often with the coil.

Probable cause
These problems, however, mostly occur as a result of external factors
such as methods and conditions of operation, and can generally be
prevented by means of careful consideration before operation and by
selecting the correct Relays.
The following table shows the main faults that may occur, their
probable causes, and suggested countermeasures to correct them.
