Mode of Operation
The relay(s) operates as
soon as the power supply is
applied.
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 reap-
plied before the relay
released the time is reset
and the relay remains ON.
The built-in battery (NiCd)
will be charged while the
power supply is applied.
Note:
DBB02 and PBB02 shoud
not be operated by pulses
shorter than 200 ms.
For these puroposes the
relays DMB01 or PMB01,
operated by external con-
tact 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.
Range/Time Setting

ting the DIP-switches 1 and

The tables indicate the
charging time needed to
keep the built-in battery fully
charged for a certain adjust-
ed 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 ter-
minals + and A2 or 7 and 10.
