The ability to maintain coin levels in the coin mech's inventory tubes is called the coin float mode. The Guardian 6000 coin mech has two types of float available, the float paydown and the level float, either mode can be set via the display menu system.

Float paydown mode will allow the coin tubes to fill to full and later they can be paid down to the set coin levels, therefore maintaining a set change level after a service call.

Level Float mode will cause the coin tubes to fill to the set level after which all additional coins will be routed to the cashbox, therefore maintaining a set change level throughout operation.

Either float mode is set by filling the tubes with the desired level of coinage, then pressing E+F to Enable Float, this will then set the float to the current level of coins. If you wish to disable the float, possibly to change the float amount, press D+F to Disable Float. To payout excess coins that have accumulated in Float Paydown mode, press C+F to start the overfill coins to be dispensed from the tubes.

See the manual for full float mode details.
