Function/Range/Level/Time Setting
Select the desired func-
tion setting the DIP-switch-
es 1 to 4 as shown on the
right. Adjust the input range
setting the DIP-switch-
es 5 and 6. To access the
DIP-switches open the plas-
tic cover using a screwdriver
as shown below.
If DIP switch 3 is set to ON
(start/stop) the position
of DIP switch 4 does not
affect the products’ working
mode.

Notes
1.
DIP-switch 3 set ON enables the start/stop function
that is managed by the closing-opening of the con-
tact input.
2.
DIP-switch 3 set OFF enables the input contact for
the latch/inhibit functions: the selection between
these is allowed by DIP switch 4.
The following table shows as the input contact man-
ages the mode of operation:
Mode of Operation (cont.)
the output relay releas-
es and the red LED turns
on after the set time has
expired. When the start/stop
contact is opened the relay
is immediately de-energized.
To restart the system just
connect the start/stop con-
tact.
Note 1:
to use the start/stop
function the output relay has
to command a contactor in
series to the load (see last
two wiring diagrams).
Note 2
(3-phase voltage):
connect the 3-phase power
supply to the terminals L1,
L2 and L3 (DWB03) - 5, 6
and 7 (PWB03) taking care
of the sequence.
