signal output shows status “good
target”. Switching signal can be inverted
with function no 8.

11 Q
1
= trigger input mode:
With rising edge on Q
1
, measured value is
held until the next trigger occurs.
On = Q
1
is a trigger input
Off = Q
1
is not a trigger input
Off
12 Q
1
= enable input mode:
Used to switch laser beam on and off.
Laser beam is on when Q
1
= +U
B
. If Q
1
= ­ U
B
, the laser beam is switched off.
Last measured value remains. When re­
activated, the response time is prolonged
according to the set mean value.
On = active
Off = not active Off
13 Switches off averaging:
The first measured value is taken into
account (page 35).
On = Averaging off On
14 Switches on 4 ms averaging:
the first 10 meas. values are taken into
account (page 35).
On = active
Off = not active Off
15 Switches on 40 ms averaging:
all (max. 100) meas. values are taken into
account (page 35). On = active
Off = not active Off
16
Set analogue output 0% (4 mA):
When S button is activated, the current
meas. value corresponds with 0% value of
the analogue output.
On* = Object within…
Off* = Object outside...
...measuring range
0% = 4 mA = end
of meas. range
17
Set analogue output 100% (20 mA): When
S button is activated, the current meas.
value corresponds with 100% value of the
analogue output.
On* = Object within…
Off* = Object outside...

automatic zero mode:
For characteristic curve displacement. If
Q
1
= +U
B
, the current measuring signal
is set to the analogue value 0 % = 4 mA.
The incline of the characteristic curve is
maintained. If exceeded, the characteri­
stic curve ends at the start or end of the
measuring range.
On = Automatic zero active
Off = Autommatic zero not active Not active
19 Q
1
automatic centre mode: displacement
of centre of characteristic curve. If Q
1
=
+U
B
, the current measuring signal is set to
the analogue value
50 % = 12 mA. The incline of the charac
­
teristic curve is maintained. If exceeded,
the characteristic curve ends at the start
or end of the measuring range.
On = Automatic centre active
Off = Automatic centre not
active
Not active
