Mitsubishi Q series... configuring an analogue voltage input

Hi, I've got a Q68AD-G card (8 channel).
I want to configure it for 0-10v analogue input.
I've enabled the channel by using Un\G0. Then I used the 'io assignment' switch setting to set my channel to range 0-10v. However, the value read at the PLC tops out at 5v (ie 5v gives a value of 4000) - further increases in voltage input have negligible effect. The channel gives me the same values if I set the 'switch settings' to 0-5v.

Is there some other place where I still need to configure the channel for 0-10v?

Thanks for the help. The final step to make the changes take effect was to cycle the PLC power. Once I'd done this it all worked as expected. 0v=0000, 10v=4000 on PLC.
