Step1. Check if any other objects can block Shutter movement and remove them perfectly
Step2. Manipulate Shutter manually if it is smoothly working or not
Check if any springs are missing or any components are bent by external force
Step3. Check if Shutter solenoid cable and ST-S1 sensor cable are firmly connected
It would be better to disconnect them and try to re-connect
Step4. Check if both ST-S1 and ST-S2 sensor are properly working by measuring sensor voltage with
blocking/unblocking conditions (unblocking : less than1.0V, blocking : over 4.5V)
Step5. Measure the coil resistance of solenoid by multi-meter and check if it will display the stable region
(15-3Ω ) If it doesn’t meet, replace with new Solenoid.
Step6. Measure the supplied voltage from CDU controller and check if it will display the stable region
(24-1.2V) If it doesn’t meet, check replace with new CDU controller board
Step7. Check if the solenoid adjustment is good (working distance = 9.0mm)
Step8. Replace Presenter Module
