n general
,
the relay control lamp indicates the
activated

A
dark relay control lamp means that the relay is

you can adjust the mode
(

).
W
ith switch
2

you can adjust the switch o

.
I
n the example
(
see previous illustration
),
mode
A
(
max

detection of over

)
is selected
(
switch
1
).
T
he
switch on delay is activated
(
switch
3
)
and the integration time
is set to
8
seconds
(
switch
4
,
5
and

).
W
ith switches
4
,
5
and

you can adjust the integration time
.
T

.
I
f the
switch on

delay
(

are switched on
together
,
the adjusted time applies to both delay modes
