shows that the ON/
OFF is changed at
a point that "1U" is
added to this value.
The direct and reverse action settings are disabled for the timer event.
When using the timer event, it is necessary to set the operation type of the DI allocation to "Timer Start/Stop".
Additionally, when setting the event channel designation of the DI allocation, multiple timer events are
controlled from individual internal contacts (DI).

• ON delay time: A period of time necessary to change the event from OFF to ON after DI has been
• OFF delay time: A period of time necessary to change the event from ON to OFF after DI has been
• The event is turned ON when DI ON continues for ON delay time or longer.
• The event is turned OFF when DI OFF continues for OFF delay time or longer.
• In other cases, the current status is continued.
When setting the ON delay and OFF delay, it is necessary to put in "Multi-function setup".
The default settings of the ON delay and OFF delay before shipment are 0.0s.
The default setting of the event channel designation of the DI allocation before shipment is "0". In this
case, the timer event start/stop can be set for all internal events from one internal contact (DI).
Additionally, as one or more event channel designation is set, the timer event start/stop can be set for one
internal event specified by one internal contact (DI).
However, when setting the event channel of the DI allocation, it is necessary to put in "Multi-function setup".
