WARNING
Risk of uncontrolled actuator movements when the pneumatics are
switched on!
There is a danger of personal injury if the system is in an undefined state.
u
Put the system in a defined state before switching it on.
Commissioning may only be carried out by qualified electrical or pneumatic per-
sonnel or an instructed person under the direction and supervision of qualified
personnel. See
.
1.
Connect the sensor to a suitable operating voltage. See
.
2.
Teach in the working stroke (two switching points) as follows:
3.
Set the first piston position for the working stroke (switching point 1).
4.
Press and hold the teach-in button for 3 seconds (
A
).
LED 1 will flash.
u
Release the teach-in button.
Switching point 1 is stored.
LED 2 will flash (for switching point 2).
u
Set the second piston position for the working stroke (switching point 2) (
B
).
Press and hold the teach-in button for 1 second (
B
).
Switching point 2 is stored.
If the switching point is outside the detection range of the sensor, the
teach-in process will be interrupted. In this case, the LED will flash in
short intervals.
If the teach-in process is not complete, it will be interrupted after
90 seconds (timeout). The last stored switching points will remain ac-
tive.
5.4 Checking the stored switching points
See
1.
Move the piston to the position of switching point 1.
The switching point 1 LED lights up: switching point recognized (
C
).
LED does not light up: switching point not recognized.
2.
If the switching point is not recognized, check the operating conditions and
readjust.
3.
Move the piston to the position of switching point 2.
The switching point 1 LED goes out and the switching point 2 LED lights up:
switching point recognized (
C
).
If the first LED does not go out or the second LED does not light up: switching
point not recognized.
4.
If the switching point is not recognized, check the operating conditions and
readjust.
6 Care and maintenance
The ST4-2P sensor is maintenance-free.
NOTICE
Damage to the surface caused by solvents and aggressive detergents!
The surfaces and seals could be damaged by solvents or aggressive cleaning
agents.
u
Never use solvents or aggressive detergents.
1.
Check the fittings and plug connections regularly.
2.
Comply with the maintenance intervals and specifications for the entire sys-
tem.
7 Disposal
Dispose of the ST4-2P sensor in accordance with the currently applicable regula-
tions in your country.
