9050JCK Electronic Timing Functions
Function Description Timing Diagram
On Delay When the input voltage is applied, the time delay begins. Relay contacts change
state after time delay is complete. When the input voltage is removed, contacts
return to their shelf state. The trigger switch is not used in this function.
Interval When the input voltage is applied, the relay contacts change state immediately
and the timing cycle begins. When the time delay is complete, or when the input
voltage is removed, contacts return to shelf state. The trigger switch is not used
in this function.
Off Delay Switch
and Power Trigger
Input voltage must be applied con inuously. When the trigger switch closes,
the relay contacts change state. When the trigger switch opens, the ime delay
begins. When the delay is complete, the contacts return to their shelf state. If
the trigger switch closes before the time delay is complete, then timing is reset.
When the trigger switch opens, the delay begins again, and the relay contacts
remain in their energized state. If the input voltage is removed, the relay contacts
return to their shelf state.
One Shot Switch
and Power Trigger
Input voltage must be applied con inuously. When the trigger switch closes, he
relay contacts change state and the pre-set delay begins. During time-out, the
trigger signal is ignored. If the input voltage is removed, the relay contacts return
to their shelf state.
