# Error description Troubleshooting advice
15 Key lock active
The SELECT button is locked
It can be unlocked by holding the ENTER button for 7s until the 4 first LEDs
has come ON .
16 Sensor target missing Verify that the sensor target is installed correctly.
17
Setup prerequisite issue
Missing peripherals
The detected solenoid valves and/or seat lift sensor does not meet the Auto
Setup prerequisites.
One or more solenoid valves might be missing.
V
erify that the solenoid valves are connected correctly to the control board.
If the solenoid valves have been rearranged intentionally, then use Flex
Setup to complete the setup.
18 Pneumatic part issue
The air hoses might overlap each other.
Verify that the installed air hoses run parallel to each other.
If the air hoses are installed correctly, then use Flex Setup to complete the
setup.
19 Seat lift sensor issue
No change of state was detected from the seat lift sensor.
Verify that the seat lift sensor installation is correct:
- Test the installation by energizing and deenergizing the upper seat lift
function and verify that the LED on the seat lift sensor changes state.
- Check the wiring on the control board.
- Check that the seat lift sensor is of the type IFT216.
20 Position not reached
During operation, the sensor target or the seat lift sensor did not reach the
intended position on time.
- Check the supply air.
- Check the performance of the process valve actuator.
- Verify that the following prerequisites for Auto Setup are met:
- The number of solenoid valves corresponds to the number of valve
functions.
- Each valve function has a related sensor input available.
- Use Flex Setup if these prerequisites cannot be met.
If Flex Setup cancels with this error, it indicates that identical position data
has been detected for two or more steps.
- Retry Flex Setup. (Press SELECT to skip unnecessary steps.)
- Verify that the seat lift sensor functions properly (if installed).
21
Unexpected process valve
movement
There is a manual override of solenoid valves or pressure shock in the
process valve.
If Auto Setup cancels with this error
, a solenoid valve trigger input might be
high.
- Reset all inputs and rerun Auto Setup.
22 Seat-lift sensor missing
The seat-lift sensor is not detected.
- Check the seat-lift sensor cable and wiring.
- Rerun setup if the seat-lift sensor has been intentionally removed.
