## **Mode of Operation/Settings**
before the relay releases the time is reset and the relay remains ON.
When the power supply is before the relay releases the applied the relay operates. time is reset and the relay When the power supply is remains ON. interrupted the time period starts and, at the end of the **Note:** set time period, the relay DBB51 shoud not be operreleases. ated by pulses shorter than If power supply is reapplied 200 ms.
For these puroposes the relay DMB51, operated by external contact function, should be used.
