When the power supply is interrupted the time period starts and, at the expiration of the set time period, the relay releases. If the power supply is reapplied before the relay released the time is reset and the relay remains ON. The built-in non-replace- able battery (Ni-MH) will be charged while the power supply is applied. Note: DBB02 and PBB02 should not be operated by pulses shorter than 200 ms. For these purposes the relays DMB01 or PMB01, operated by external contact function, should be used. The battery test is per- formed on terminals + and A2 or 7 and 10. It is recommended to con- nect DBB02 and PBB02 to the power supply for 42 h before it is put into regular service in order to compen- sate for energy losses due to, for example, a long stor- age period.

Specifications are subject to change without notice (14.04.20) 3 DBB02, PBB02 Wiring Diagrams Curves DBB02 PBB02 The tables indicate the charging time needed to keep the built-in battery fully charged for a certain adjusted time period. Example Adjusted time period 10h, battery charging time will be about 2.2 h. At 5 operations: 5 x 10 h, bat- tery charging will be 5 x 2,2 h. If the calculated charging time cannot be obtained, then the battery voltage has to be checked, as it must not drop below 4.2 VDC (min. battery voltage). Test can be perfomed on terminals + and A2 or 7 and 10.
