pump or the source generating the cleaning solution pressure must switch off
automatically.
Hint!
Please note that test procedure 2 has to be performed with great care.
There is a danger of cleaning solution mixing with product if the
control system interlocks are not working correctly. Make sure that
there is no product in the valve body, which is not part of the active
CIP circuit, for the duration of the test!
Step 1
Make sure that the valve being tested is part of an active cleaning circuit and
determine which of the two housings is part of this active cleaning program.
Step 2
Carry out the following steps:
1.
If the upper housing is part of the active CIP circuit:
Activate lifting of the lower seat by activating solenoid valve Y2 via the PLC.
2.
If the lower housing is part of the active CIP circuit:
Activate lifting of the upper seat by activating solenoid valve Y3 via the PLC.
®
Done
Step 3
If the programmed control system interlock is working correctly, the CIP supply
pump will be deactivated. If the CIP supply pump or source for generating
cleaning solution pressure is not deactivated, immediately shut down the system
and perform a programmed lockout test.
