Switch Trigger
Input voltage must be applied continuously.
When the trigger switch closes, the relay
contacts change state. When the trigger switch
opens, the time 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.
Input voltage must be applied continuously.
When the trigger switch closes, the 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.
When input voltage is applied, the time delay
T1 begins. When time delay T1 is complete, the
relay contacts change state for time delay T2.
This cycle repeats until the input voltage is
removed. The trigger switch is not used in his
function.
NOTE: Two dials are provided for
independently adjustable repeat cycle timing
ranges. For JCK70 timing relay, T1 equals T2.
When input voltage is applied, the relay
contacts change state immediately and time
delay T1 begins. When time delay T1 is
complete, the contacts return to heir shelf state
for time delay T1. This cycle repeats until the
input voltage is removed. The trigger switch is
not used in this function.

delay relay is ready to accept trigger signals.
When the trigger switch closes, a pre-set On
delay begins. At the end of the On delay, the
relay contacts change state. When the trigger
switch opens, he relay contacts remain in the
current state until the pre-set Off delay elapses.
At the end of the Off delay, the relay contacts
return to their shelf state. The cycle can be
repeated by re-closing the trigger switch after
the timing cycle ends.
If the trigger switch opens before the On delay
elapses, the relay remains in its shelf state, and
the delay imer resets. If the trigger switch recloses before the Off delay elapses, the relay
remains in its changed state, and the delay
timer resets.

delay relay is ready to accept trigger signals.
When the trigger switch closes, the relay
remains in its shelf state. When the trigger
switch opens, he relay contacts change state
and a pre-set time delay begins. At the end of
the time delay, the relay contacts return to heir
shelf state unless the trigger switch closes and
opens before the time delay elapses.
Continuous cycling of the trigger signal at a rate
faster than the time delay causes the relay to
remain in its changed state.
Upon application of input voltage, the time
delay relay is ready to accept trigger signals.
When the trigger switch closes, the relay
contacts change state and the pre-set time
delay begins. At the end of the time delay, the
relay contacts return to their shelf state unless
the trigger switch closes and opens before the
time delay elapses. Continuous cycling of the
trigger signal at a rate faster than he delay time
causes the relay to remain in its changed state.
Upon application of input voltage, the time
delay relay is ready to accept trigger signals.
When the trigger switch closes, a pre-set ime
delay begins. At the end of the pre-set time
delay, the relay contacts change state and
remain in that position as long as either the
trigger signal is maintained or he input voltage
remains. If the trigger switch opens during the
time delay, the relay contacts return to their
shelf state.
