## • _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 “Function” selector ➎ to the required position[1] . 

- Set the “Range” ➍ to the required position choosing seconds, minutes or hours then set the “Set %” adjustment ➌ as required. The “Set %” is a % of the selected range, so 60% of the 1 – 10 hour range will give 6 hours. 

- _Applying power._ 

- Apply power and the green LED ➊ will illuminate or start flashing depending on Function selected. If a Switch initiated function is selected, the LED will begin flashing upon closing of the external input. 

- The red relay LED ➋ will illuminate to indicate the relay is in the energised state. 

## _Note:_ 

- _1 If the “Function” selector is changed whilst the power is applied, the relay will remain in its current state and the green LED will flash at a faster rate. Power must be removed and re-applied for the new Function to operate._ 

- _2 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._ 

- _3 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._
