• INSTALLATION AND SETTING<br>**----- End of picture text -----**<br>


Installation work must be carried out by qualified personnel. 

- BEFORE INSTALLATION, ISOLATE THE SUPPLY. 

- Connect the unit as shown in the diagram below. 

- If 24V AC/DC operation is required then terminals “A1” and “A3” must be linked. 

_Setting the unit._ 

- Set the “Delay (t)” adjustment ➋ as required. 

_Applying power._

- Apply power and the green LED ➊ will illuminate. 

- The relay will energise and contacts 15 and 18 close. 

- When the power is removed, the green LED will extinguish. The relay will remain energised for delay period “t” then de-energise. Contacts 15 and 18 will open. 

_Note:_ 

The supply must be maintained for a minimum period of 500mS (ts) for correct operation. For the 10 minute version, the minimum period is 1 second.
