β€’ INSTALLATION AND SETTING
**----- End of picture text -----**
- Installation work must be carried out by qualified personnel. - BEFORE INSTALLATION, ISOLATE THE SUPPLY. - Connect the unit as required. - _Setting the unit._ - Set the β€œRange” ➍ to the required position (depending on whether seconds, minutes or hours are required). - Set the β€œSet %” adjustment ➌ as required. The β€œSet %” 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 β€œA1” and β€œA2” and the green LED ➊ will start flashing indicating timing in progress. - The relay will remain de-energised (contacts **15** / **16** and **25 / 26** closed, **15** / **18** and **25 / 28** open) and red LED βž‹ extinguished. - After the delay period β€œt” has elapsed, the relay will energise (contacts **15** / **16** and **25 / 26** open, **15** / **18** and **25 / 28** closed) and the red LED will illuminate. - The green LED will remain permanently lit. - The whole timing process is repeated by removing and re-applying power. ## _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._ - _2 The dip / interruption (reset) duration and levels are defined in the product standard however, the standard allows for these to be different from the levels actually specified._ **==> picture [362 x 159] intentionally omitted <==** **----- Start of picture text -----**
