- _INSTALLATION AND SETTING_ 

Installation work must be carried out by qualified personnel. 

- BEFORE INSTALLATION, ISOLATE THE SUPPLY. 

- Connect the unit as required. 

_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 start flashing indicating timing in progress. 

- The relay will remain de-energised (contacts **15** / **16** closed and **15** / **18** open) and red LED ➋ extinguished. 

- After the delay period “t” has elapsed, the relay will energise (contacts **15** / **16** open and **15** / **18** 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. The dip / interruption duration and levels are defined in the product standard._
