## • _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), then set the “Set %” adjustment ➎ 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 start flashing to indicate timing is in progress. Contacts 15 and 18 will close as soon as power is applied (Instantaneous Relay - RLY1) and the red relay LED ➌ will illuminate. Contacts 25 and 26 (Timed Relay - RLY2) will remain closed during this period 

- At the end of the delay period “t” contacts 25 and 26 will open 25 and 28 will close. The red relay LED ➋ will illuminate. 

- Both relays will remain in the energised state until power is removed. Re-applying power will repeat the whole process again.

_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._
