Timing Modes
Delay on operate – Delay period begins when input voltage is applied. At
the end of the delay period, the relay will operate and will not release until
input voltage is removed. Reset occurs when input voltage is reapplied.

Delay on release – Input voltage must be applied continuously to operate
the internal relay. When control Input is applied, the relay energizes.
When control input is removed, timing begins. When timing is complete,
the relay will de-energize. Time may be reset to zero during timing by
reapplying control input.
