OPERATIONAL FEATURES
On application of continuous supply voltage, the ‘Power’ LED illuminates. The ‘Relay’ LED illuminates and the timed contacts operate when the external start contact is closed. The action of the start contact being opened initiates the timing circuits and the timed contacts release at the end of the time period. At this stage the ‘Relay’ LED is extinguished and the unit resets automatically. If, after the timing circuit has been initiated by the first opening of the start contact, the start contact is again closed (before the set time period has expired) the timing circuit returns to zero with no change in the output contacts or LED state.
