Testing the optical diaphragm rupture sensor

Checking the condition of the diaphragm rupture sensor
Make sure that all surfaces, especially any surfaces that come into
contact with food products, are not scratched by tools, cleaning
agents, auxiliary agents etc., and that these surfaces are not
changed in any other way.
Carry out a commissioning process after all work or longer periods

2. If the piston of the diaphragm rupture sensor, see , item 4,
should have become dirty or damp, clean both the piston and
the hole in which it runs.
3. Check whether the piston can move freely in the hole.
4. Reassemble the clean diaphragm rupture sensor with the
clean piston.
5. Testing the diaphragm rupture sensor:
1. Unscrew the transparent cover from the diaphragm rupture
sensor.
2. Press the red cylinder into the diaphragm rupture sensor until
