Combining timing functions
Timing functions can only be combined to a limited extent. Impermissible combinations are suppressed from the subfunctions menu.
Here is an overview of the permissible combinations (•):
Operating mode ADJ - teaching the switching outputs
(CH1/CH2)
Switching outputs OUT1 and OUT2 can be taught individually. Set the selector switch for the channel
to the desired position
CH1
(switching output OUT1) or
CH2
(switching output OUT2).
Set the selector switch for the operating mode to the
ADJ
position.
Depending on the setting of the
Select teach mode
subfunction (
tch
SEL1
/
tch
SEL2
), one of the following teach modes appears:
Static 1-point teach
Static 2-point teach
Dynamic teach
Teach process
Tip!
For reliable function, the difference between the signal value while an object is present and the signal value with no object should be at
least 10 … 20%. In general: the larger the difference, the more reliable the detection.

Place object in light beam.
The red display shows the signal value, the green
display the current switching threshold.
Place object in light beam.
The red display shows the signal value, the green
display the current switching threshold.
Press the rocker push button. The green display
shows
dYn
, the red display the current signal
value.
The amplifier now scans signal values for approx. 1
minute.
Press the rocker push button; the teach value is
accepted.
Press the rocker push button,
first
teach value is
accepted.
Move several objects through the light beam; to
end the event, press the rocker push button again.
After the scanning time elapses, the teach event
ends automatically.
Following a successful teach,
PASS
appears on
the green display and the signal value is displayed
as the new switching threshold.
In the event of a faulty teach,
FAIL
appears on the
red display. In this case, the signal value may be
too small and cannot be accepted as a teach value
(
Table with minimum teach values as a func-
tion of the setting
).
Check object and/or placement and repeat event.
2nd
appears on the green display; the red display
shows the current signal value.
Place object 2 or object at distance 2 and press the
rocker push button
within one minute
. The
sec-
ond
teach value is accepted.
If the rocker push button is not pressed within one
minute, the teach event is interrupted and the pre-
vious switching threshold is retained.
Following a successful teach,
PASS
appears on
the green display. The new switching threshold
now lies approximately midway between the two
taught signal values.
In the event of a faulty teach,
FAIL
appears on the
red display. In this case, the minimum distance
between the two teach points may be too small (
Table with minimum teach values as a function
of the setting
).
Try to set a larger distance between the two signal
values and repeat the event.
Following a successful teach,
PASS
appears on
the green display. The new switching threshold
now lies between the maximum and the minimum
of the scanned signal values.
In the event of a faulty teach,
FAIL
appears on the
red display. In this case, the minimum distance
between the scanned signal values may be too
small (
Table with minimum teach values as a
function of the setting
).
Try to set a larger distance between the signal val-
ues and repeat the event.
The switching threshold can be freely increased or
decreased at a later time by rocking the rocker
push button to the left (
+
) and right (
-
).
The change is accepted if both displays flash
briefly several times.
