## **Mode of O eration p** 

## **Function Op Delay on operate** 

The time period begins as soon as the trigger contact is closed. 

At the end of the set delay time the relay operates and does not release until the trigger contact is closed again or the power supply is disconnected. If the trigger contact is closed before the end of the delay time, the device resets and a new time period starts. 

## **Function In Interval** 

The relay operates and the time period begins as soon as the trigger contact is closed. The relay releases at the end of this period 

keeps ON and a new time period begins.

If **Function Id** the trigger contact is closed **Double interval** before the end of the delay The relay operates and the time, the device resets and a time period begins as soon new time period starts. as the trigger contact is closed. The relay releases **Function Io** at the end of this period or **Interval on trigger open** when the power supply is The relay operates and the disconnected.  When the time period begins as soon trigger contact is opened as the trigger contact is the relay operates again for opened. At the end of the the set delay period. If the set delay or when the power trigger contact is opened supply is disconnected the before the end of the first relay releases. The relay time period the second one operates again when the begins; if the trigger contact trigger contact is opened is closed before the end of again. If the trigger contact the second time period the is opened before the end device resets and the first of the delay time the relay time period begins again. 

## **Function Dr** 

## **Delay on release** 

The relay operates as soon as the trigger contact  is closed. The time period begins when the trigger contact is opened. The relay releases at the end of the set delay time or when the power supply is disconnected. The relay operates again when the input contact is closed again.  If it is opened before the end of the delay time the relay keeps ON, a new time period begins as soon as the contact is closed again. 

## **Function R** 

**Symmetrical recycler, ON-time period first** The relay operates and the time period begins as

## **Mode of Operation (cont.)** 

soon as the input contact is closed. The relay is OFF during the set delay period, after this time it operates for the same time period. This sequence continues with equal OFF- and ON-time periods until the power supply is interrupted.

## **Additional Load** 

It’s possible to wire an additional load (i.e. a relay) 

between pins Y1 and A2, driven by the trigger contact without damaging the device.
