Electrical diaphragm rupture sensor
4. Reassemble the clean diaphragm rupture sensor with the clean
piston.
5. Test 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 the
cylinder engages.
3. Press the piston on the other side of the diaphragm rupture sensor
into the dosing head (approximately 4 mm) using a blunt, smooth
object until it triggers.
CAUTION!
Feed chemical may escape
Feed chemical can escape in the event of a dia‐
phragm rupture if the expandable flap of the dia‐
phragm is damaged.
Make sure that the piston is not scratched. It must
remain completely smooth so that the piston does
not damage the expandable flap of the diaphragm
during operation.
4. Press the red cylinder into the diaphragm rupture sensor again and
repeat the test.
5. If it does not trigger both times, replace the diaphragm rupture
sensor.
6. After a successful test, screw the transparent cover onto the dia‐
phragm rupture sensor and then continue at the top by assembling
the diaphragm.
1. Press the piston of the diaphragm rupture sensor into the dosing
head (approximately 4 mm) using a blunt, smooth object until the
monitor triggers an alarm.

2. Repeat the test.
3. Replace the diaphragm rupture sensor if the monitor does not
