What to do if Alfa Laval ThinkTop V70 displays 'Setup prerequisite issue Missing peripherals'?
- J
  jesse85Aug 21, 2025
  If the Alfa Laval Control Unit displays 'Setup prerequisite issue Missing peripherals', it means the detected solenoid valves and/or seat lift sensor do not meet the Auto Setup prerequisites. Verify that the solenoid valves are correctly connected to the control board. If the solenoid valves have been intentionally rearranged, use Flex Setup to complete the setup.

What to do if Alfa Laval ThinkTop V70 displays 'Setup aborted'?
- A
  Allen BrownAug 22, 2025
  If the Alfa Laval Control Unit displays 'Setup aborted', it means that the setup was cancelled due to a timeout, pressing SELECT, or a detected fault condition. No changes are saved when setup cancels. To resolve this, rerun setup.

What to do if Alfa Laval ThinkTop V70 Control Unit shows 'Safety stop'?
- J
  Jordan TurnerAug 25, 2025
  If the Alfa Laval Control Unit displays a 'Safety stop' message, it means the sensor target has moved beyond the sensing range limit. This triggers a safe mode to prevent damage to the unit's housing. To resolve this, first, check that the actuator stroke length is compatible with the control unit. For instance, long stroke valves may not be suitable for the V50 housing. Also, ensure the yellow sensor target provided with the control unit is correctly fitted.

What to do if Alfa Laval ThinkTop V70 displays 'Position not reached'?
- A
  andrew82Aug 27, 2025
  If the Alfa Laval Control Unit displays 'Position not reached', it indicates that the sensor target or seat lift sensor didn't reach the intended position on time during operation. Check the supply air and the performance of the process valve actuator. Verify that the number of solenoid valves corresponds to the number of valve functions and that each valve function has a related sensor input available. If not, use Flex Setup. If Flex Setup cancels with the same error, it means identical position data has been detected for two or more steps. Retry Flex Setup, skipping unnecessary steps by pressing SELECT. Also, verify that the seat lift sensor functions properly, if installed.

What to do if Alfa Laval Control Unit displays 'Unexpected process valve movement'?
- D
  David OconnellAug 30, 2025
  If the Alfa Laval Control Unit displays 'Unexpected process valve movement', this may be due to a manual override of solenoid valves or pressure shock in the process valve. Reset all inputs and rerun Auto Setup to resolve the issue.

- C
  Cathy LongAug 31, 2025
  If the Alfa Laval Control Unit displays 'Voltage Low', it means that too low supply voltage has been detected. Verify that the voltage is above 21V.
