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 the control switch is closed, the relay energizes.
When the control switch is opened, timing begins. When timing is
complete, the relay will de-energize. Time may be reset to zero during
timing by closing the control switch.
Interval on – The relay energizes and timing begins when input voltage is
applied. At the end of the time delay period the relay will de-energize.
Reset is accomplished by removing, then reapplying, the input voltage.
