Range/Time Setting
Adjust the time range set-
ting the DIP-switches 1 and

To access the DIP-switches
open the plastic cover using
a screwdriver as shown
below.

Mode of Operation
When the power supply is
applied the relay operates.
When the power supply is
interrupted the time period
starts and, at the end of the
set time period, the relay
releases.
If power supply is reapplied
before the realy releases the
time is reset and the relay
remains ON.
Note:
DBB01, PBB01 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.
