The relay operates immedia-
tely after power supply is ap-
plied.
When power supply is inter-
rupted the time period starts
and at expiration of the set
time period the relay releases.
If power supply is reapplied
before the relay has released,
the time is reset and the relay
remains on.
The built-in battery (NiCd) will
be charged while power sup-
ply is applied.
Note:
The EBB should not be ope-
rated by short pulses. For this
purpose the relays EMB C T23,
operated by means of an ex-
ternal contact function, should
be used.
Battery test is performed on
terminals + and A2.
It is recommended to connect
the EBB to the power supply
for 42 h before it is put into re-
gular service in order to com-
pensate for energy losses due
to e.g. a long storage period.

The above tables indicate the
charging time needed to keep
the built-in battery fully
charged for a certain adjusted
time period.
Example
Adjusted time period 60 s,
battery charging time will be
32 s.
At 5 operations: 5 x 60 s, bat-
tery charging time will be 5 x
32 s.
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 performed on ter-
minals + and A2.
