_Setting the unit._
- Set the “Range” ➍ to the required position (depending on whether seconds, minutes or hours are required).
- Set the “Set %” adjustment ➌ as required. The “Set %” is a % of the selected range; so for example, a 30% setting on the 1 – 10 hour range will give 3 hours.
- _Applying power._
- Apply power across terminals **A1** and **A2** and the green LED ➊ will illuminate.
- The relay will remain de-energised (contacts **15** / **16** closed and **15** / **18** open) and red LED ➋ extinguished.
- Close the contact across **A1** and **B1** and the relay will energise (contacts **15** / **16** open and **15** / **18** closed) and red LED illuminate.
- When the contact across **A1** and **B1** opens, the delay period “t” will begin and the green LED will flash to indicate timing is now in progress.
- After the delay period “t” has elapsed, the relay will de-energise (contacts **15** / **16** closed and **15**
- / **18** open) and the red LED will extinguish.
- The green LED will now remain permanently lit.
- The whole timing process is repeated by removing and re-applying power.
- If during the time period “t”, the contact across **A1** and **B1** closes, timing will stop and restart over again the next time the contact opens.
_Note:_
> _1 In accordance with IEC 61812, the green LED is permitted to extinguish during a voltage dip or momentary interruption of the power supply providing the state of the output relay does not change. The dip / interruption duration and levels are defined in the product standard._
