reference point not working

[Pridefull]

Hello all

I have a problem with our lathe with Fanuc oi-TB control and that is i cant reference the machine on startup ( the reference button doesnt light up when pressed). i have tried more or less anything i could think of including keeprl and param. 1815 to set up the new reff. point but no success.
and when i try to call g28 in mdi alarm 090 pops up.

Any idea would be helpful

thanks in advance

Move X & Z into machine area...
home X before Z ... then home (index) turret.... the live spindle should orientate before indexing.

any other messages/alarms ?
