Starting the CIP
For a quick key reference please open the Operator Panel folder in the back of this manual.
By pressing the pump start key K4 the CIP will start, the CIP Sequencer Screen will be displayed and
the LED L4 will light up, if neither the pumps, dasher and compressor is running and the Test Mode
function is off. If one or more of these conditions are not met the CIP will not start.
By pressing K4 once more the CIP Sequencer will stop, L4 will turn off and the main menu screen
displayed.
The CIP Sequencer will cyclically perform the following 3 steps:
Step 1: Flushing Cylinder.
Step 2: Running Dasher and Pumps
Step 3: Flipping Pump Covers
The duration of the steps can be adjusted in the Set Up Menu in the Sub Menu “CIP”.
When step 3 is finished the sequencer will do the steps again until CIP maximum time runs out or CIP
is terminated by pressing K4.
The CIP Sequencer can be controlled from an external CIP plant by using the Digital Input “CIP
Acknowledge”, see the electrical diagrams for reference. This input is normally wired to 24VDC and is
therefore “On”. If the 24VDC signal is removed the input goes “Off” and the CIP Sequencer will
pause. It will remain in the pause state until the input goes high again.
The following errors can also pause the CIP Sequencer:
Error 1: Dasher Breaker Tripped.
Error 3: Pump Breaker Tripped.
Error 5: Pump VFD Faulted.
For a closer description of the errors see the alarm section.
