Conveyor 3.6.21 Replacing the Ultrasonic Sensor PXS240 [03069863-xx]

Removal

► Use the software to move the conveyor sides into the position which allows you best access. As an

alternative, you can loosen the clamps for the relevant sides in dual conveyors.

► Switch off the machine, disconnect it from the power supply and secure it to prevent unauthorized

reactivation. Observe the instructions in section "1.2 Preparatory Work..." [ ➙ 12].

► Dismantle the cover plate on the sensor rail.

If you need to replace the ultrasonic sensor behind the conversion board, perform the steps described

below:

► Remove a different, functional ultrasonic sensor from the rail by following the instructions above.

(You can then fit the new ultrasonic sensor in its place.)

► Fit this ultrasonic sensor in the position behind the conversion board and reestablish all connections

to the ultrasonic sensor.

► Fit the conversion board and reestablish all connections to it.

Background: the ultrasonic sensor behind the conversion board is not easily accessible for any teaching

procedures which may be required. This exchange of sensors means that this ultrasonic sonar does not

need to be taught.

► If needed, the sensor rail can be removed to allow

better access. Simply loosen the two screws (1) on

the ends of both shafts.

► If you need to replace the ultrasonic sensor behind

the conversion board, dismantle it first. Unplug all

connections. You may want to mark the positions, to

make clear assignment easier later on.

► Loosen the screws (1) fastening the ultrasonic sen-

sors.

► Unscrew the press-fit connection (2) from the ultra-

sonic sensor and remove the ultrasonic sensor from

the machine.

Installation

► Follow the removal instructions in reverse order for installation of the new ultrasonic sensor. Also ob-

serve the following instructions:

Assembly at the stopper positions

► Insert the sockets into the sensor:

1. For sonar sensors on the sensor rail of the right side, you need to position the sockets on the right,

as viewed from the connection side.

2. For sonar sensors on the sensor rail of the left side, you need to position the sockets on the left, as

viewed from the connection side.

1. Sonar sensor

2. Threaded socket P+F [03096703-xx] (oval)

3. Press-in threaded insert M2 [03088352-xx] (round)

NOTICE

Recommendation: fix socket with adhesive

The sockets do not need to be fixed with adhesive for technical reasons. However, for easier

assembly it may be advisable to fix them like this. This helps to prevent them from falling out or

from the socket being turned with other parts.

► Use suitable adhesive to fix the sockets. It should be designed to bind plastics with metal

e.g. Loctite 401 [00805104-xx].

Assembly Differences on the Conversion Board

► Observe the following differences during assembly on the conversion board at the end of PA1 and

at the beginning of PA2:

Functional check

► Perform a function check. If this is not successful, you will need to reteach the sonar sensor. (see

"5.5.2 Teaching the Sonar Sensor PXS240" [ ➙ 256]).
