Series Sanitary Mixproof Valve Instruction Manual
Valve Seat Position Indication
Test procedure listed as follows:
1. Select a Unique PMO Plus CP HT mixproof valve for interlock testing.
2. Decide if the cleaning solution will flow through the mixproof valve upper or
lower body as part of the CIP cleaning circuit for the test.
3. Start the appropriate CIP circuit. (WARNING: be sure that there is no risk of
mixing product with cleaning solution when conducting this test!!)
4. The CIP supply pump, or source of CIP solution pressure, should now be
operating.
5. Remove the cover lid from the Think Top.
Move to step 6 or 7 below:
6. If cleaning solution is flowing through the valve upper body, push and hold
the silver manual air pilot button on solenoid number 2 (lower seat push). If
control system interlock is correct, the CIP supply pump, or source of CIP
solution pressure, will be de-activated. Release manual air pilot button to
end this test.
7. If cleaning solution is In the tank, push and hold the silver manual air pilot
button on solenoid number 3 (upper seat lift). If the control system interlock
is correct, the CIP supply pump, or source of CIP solution pressure, will be
de-activated. Release manual air pilot button to end this test.
8. If the control system does NOT de-activate the cleaning solution pressure
source as described in either 6 or 7 above, the control system should be
shut down for evaluation, and correction, to the interlock functions written
in the PLC logic.
** If solenoids are located in a remote enclosure (not inside Think Top), the
above test procedures are to be conducted in exactly the same method.
Selection of the proper solenoids for testing are to be determined using the
assistance of plant operating personnel.
