How to unlock Alfa Laval Control Unit if key lock is active?
If the key lock is active on the Alfa Laval Control Unit, the SELECT button is locked. Unlock it by holding the ENTER button for 7 seconds until the first 4 LEDs turn ON.
What to do if Alfa Laval ThinkTop V50 displays 'Voltage Low'?
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.
What to do if Alfa Laval ThinkTop V50 Control Unit displays 'Unexpected process valve movement'?
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.
What to do if Alfa Laval ThinkTop V50 Control Unit displays 'Hardware fault'?
If the Alfa Laval Control Unit displays a 'Hardware fault' message, it indicates that an unrecoverable hardware fault has been detected. The suggested solution is to replace the control board.
What to do if Alfa Laval ThinkTop V50 Control Unit displays 'Position not reached'?
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 ThinkTop V50 Control Unit shows 'Safety stop'?
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 V50 displays 'Setup aborted'?
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.
