8 Commissioning
Warning
• Keep hands away from moving parts (see section 6).
During commissioning, you need to define the positions of the actuator and/or
process valve in which the sensor box is to return the desired signals (end
position 1, end position 2, and mid-position if applicable). This is done by moving
the rotating reed switch holders on the shaft (Fig. 1 6 ) into the desired position.
When the fixing screw is loosened, all reed switch holders can be moved manually
with e.g. a pin. The reed switch holders for the end positions can also position
themselves automatically with the aid of the driver.

Manually adjusting the reed switch holders
1. Loosen the fixing screw (Fig. 12 2 or Fig. 13 1 ) by unscrewing it ¼ to ½ turn –
do not unscrew it all the way out!
2. Carefully move the reed switch holders (Fig. 12 1 , 3 , 6 ) into the desired
position using e.g. a pin.
3. Now, check the signalling response of the sensor box in a test run. When a reed
switch is actuated, the corresponding LED lights up (see Fig. 1 7 ). If an error
was made, repeat point 2.
4. Finally, re-tighten the fixing screw till finger-tight.
Automatically positioning the reed switch holders for the end positions
In clockwise operation, the reed switch holder for end position 1 is usually brought
into the desired position first; in anti-clockwise operation, the reed switch holder
for end position 2 is brought into position first. Fig. 13 shows an example of how
the driver in hole a moves the reed switch holder for end position 1during a clock-
wise rotation: 3 1 is the starting position and 3 2 is the final position.

Reed switch holder,

1. Loosen the fixing screw (Fig. 13 1 ) by unscrewing it ¼ to ½ turn – do not un-
screw it all the way out!
2. With SRBP-...-A-: move the reed switch holder for mid-position outside of the
angle of rotation (see Fig. 13 6 ). The driver (see Fig. 13 5 ) is only used for
moving the reed switch holders for end positions.
3. Align the reed switch holders for the end positions so that they can be picked up
by the driver during rotation when the driver is in the corresponding hole (see
Fig. 12 4 a or b).
4. To set end position 1 (clockwise rotation):
a) Insert the driver into hole a (see Fig. 12 4 ).
b) Move the actuator into end position 1.
5. To set end position 2 (anti-clockwise rotation):
a) Insert the driver into hole b (see Fig. 12 4 ).
b) Move the actuator into end position 2.
6. Pull the driver back out of the hole.
7. With SRBP-...-A-: carefully move the reed switch holder for mid-position into the
desired position by hand – using e.g. a pin.
8. Now, check the signalling response of the sensor box in a test run. When a reed
switch is actuated, the corresponding LED lights up (see Fig. 1 7 ). If an error
was made, repeat points 2. to 8.
9. Finally, re-tighten the fixing screw till finger-tight.

9 Operation
• Compare the maximum values specified in these operating instructions with
your actual application (e.g. pressures, forces, torques, masses, speeds, tem-
peratures). The product can only be used in accordance with the relevant safety
guidelines if the maximum load limits are observed.
10 Service and maintenance
If used as designated in the operating instructions, the device will be free of
maintenance.
• Clean the outside of the product with a soft cloth. The permitted cleaning agent
is soap suds.
11 Removal and repairs
Make sure that the following energy sources are switched off:
– Electrical power supply
– Compressed air supply
• Remove the sensor box in the reverse order of installation
( section 7.1).
