- Apply power and the green LED ➊➊ will start flashing to indicate timing is in progress. 

- • The red relay LED ➋ will illuminate to indicate the relay is the energised state when the “tON” ➋ will illuminate to indicate the relay is the energised state when the “tON”  will illuminate to indicate the relay is the energised state when the “tON” ON” ” delay is running. 

- When the “tOFF” delay is running and relay is de-energised, the red LED will remain extinguished. 

- • If the Delayed Pulse function is selected, the green LED will stop flashing and remain illuminated when the relay de-energises after the “tON” period. 

_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._
