D70 .250 (6.35) Dia 2.000 (50.8) 1 .250 (6.35) 2.000 (50.8) OPERATION 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 deenergize. Time may be reset to zero during timing by closing the control switch.
