Handling Precautions
• Be sure that the event output does not exceed the specified output rating
of this controller. When driving a relay, use the relay with a built-in diode
for coil surge absorption. Doing so might cause faulty operation.

Handling Precautions
• When using a relay for external switch input, always use a relay designed
for micro-current use (with gold contacts).
Failure to do so cold cause faulty contact, resulting tn malfunction.
