19. The fan can be switched on and off on the display of the
PLC. The correct direction of rotation of the fan is shown by
the arrow on the fan.
Perform the following steps if the booster pump and/or the
fan are rotating in the wrong direction:
n
Use the main switch to switch off the system
n
Swap phases 2 and 3 of the main power supply
n
Use the main switch to switch on the system once you
have swapped the phases.
20. Use the screwdriver supplied with the scope of delivery to
turn the screw in the sensor air flow. With the fan running,
turn the screw until the LED just turns green. The LED should
turn red within 2 minutes when the fan is no longer running.
21. On the PLC display, press
[Start-up] and check whether the
caustic tank fills up with process water.
22. On the display of the PLC, check in the relevant sub-menu
whether the flow is being measured.

WARNING!
Chlorine gas
Possible consequence: fatal or very serious
injuries.
Before commencing production, make sure
that lye is filling into the caustic tank.
Chlorine gas can be released if production is
started without lye.
CAUTION!
Danger due to lye
Possible consequence: Danger to health
from lye
Make sure that all blanking plates are
removed on the membrane cell and the
vacuum transmitter, otherwise lye can
escape and cause serious health problems.
Make sure that all ball valves, apart from the
sample valve, are open, otherwise lye could
leak out and cause serious health problems.
Check that there is sufficient lye in the caustic tank. The
quantity of lye needed for each capacity is listed on page 1 of
the test protocol.
24. Check that there is sufficient brine in the membrane cell.
Check that there is salt in the brine tank.
Check that brine is being pumped into the membrane cell,
after several manual updates.
25. Check that the booster pump is running and that the caustic
tank stops filling. The caustic tank stops filling when the min‐
imum level in the production tank has been reached.
26. Check that all customer-specific components are operating
correctly. The customer-specific components in question are
listed on page 1 of the test protocol.
