Note: 1. HOLD: The previous output condition will be on hold when an error results.
LOAD OFF: All outputs will be OFF when an error results.

3. Information on EC Directives
Individual OMRON products that comply with EC Directives conform to the common emission standards of EMC Directives.
However, the emission characteristics of these products installed on customers’ equipment may vary depending on the configu-
ration, wiring, layout, and other conditions of the control panel used. For this reason, customers are requested to check whether
the emission characteristics of the entire machine or equipment comply with the EMC Directives.
