Need Help!- Bridgeport 560/22 swarf conveyor coollant pump not working? Help needed :)

[dws_engineering]

Turned on m/c this morning and the coolant overflow warning came up on the screen, turns out the motor isn't kicking in when the float is raised.
The motor works as flicked the contactor over on the switch and works as should. but won't do it when the float is raised.
It seems like there is a timer on the float switch that tell the n/c that the float switch has been up for too long. and flashes up 'swarf conveyor coolant overflow'
Is there a fuse or a relay gone somewhere? was working fine yesterday.
any help would be great as got so much work to do on it.

many thanks
David

The float switch relay is working as it should. so really unsure as to what the problem is

does anyone know what parameters that controll of the swarf conveyor and the float switches are?
