1. Ensure that the fixing screws enter the cylinder at a depth of at least 5mm. The length of the fixing screws
depends on the thickness of the used lock case and possible accessories installed between the lock case
and the cylinder. If necessary, cut the screws. Attention: If the lock case needs a tail piece to be left in a
horizontal position, use the iLOQ AC50.1 accessory with the cylinder. See chapter 4 for details.
2. Adjust the knob to the desired distance from the cylinder body, so that, for example, high-security
escutcheons can fit in between. Cylinder versions with a long reader (C50S.X2X.SD) can be adjusted by a
maximum of 4 mm and cylinder versions with a short reader (C50S.X1X.SD) can be adjusted by a maximum
of 2 mm.
3. Test the cylinder functionality after installation to ensure that it doesn’t prevent the lock case from working
properly. iLOQ S50 lock cylinders feature an automatic reset back to a locked state. It is therefore necessary
to perform the following test:
• Open the cylinder with a valid key
• Turn the reader knob to a full right/left lock position for 15 seconds until the cylinder automatic resets.
Release the reader knob to ensure that it is not preventing lock-case functionality.
4. If the test fails (for example, the lock case gets stuck in an open position), you will need to adjust the tail
plug. See chapter 6 for instructions on how to adjust the tail plug.
