tubes. Changing the Par setting to Par to Value sets the default to $50. Any coins in excess
of $50 will be deposited in the cashbox.
• Par Mode: Adjust the type of Par the machine uses to manage coins
o Level – Sets the fill level for each coin. Coins above that level are sent to the
cash-box.
o Value – Sets the fill level to a total cassette value. Once the value is achieved,
coins are sent to the cash-box. Gryphon dynamically alters the individual coin
levels to minimize the need for manual refills.
o Auto – Gryphon determines the optimal par level for your machine based on
actual coin usage.
• Target Value: Sets the cassette threshold for Par to Value. Anything in excess of this
number will be routed to the cash-box.
• Target Levels: Sets the levels for Par to Level. Coins above each set level will be

GRYPHON OPERATION AND SERVICE GUIDE
CHANGE MANAGEMENT
Introduction
The Gryphon has many features that allow the product to be called a change manager
rather than a change giver. In addition to the high capacity six tube cassette, these features
enable the Gryphon to more effectively manage the operation of the unit and to optimize the
float levels of the machine and the change payout. These features provide an opportunity for
the operator to optimize vend revenue by minimizing the amount of time the unit operates in
exact change mode.
Float to Level
What is Float to Level?
Each tube can be filled to a specific level, after which the coins are routed to the cash box.
This is the traditional float style, also known as Par. To set this up, enter the total number of
coins of that type that you want to store in the changer. This level applies to all tubes holding
the same type of coin. For example, if the level was 30, and the coins were stored in three
tubes, there will be ten coins in each tube.
Float to Value
What is Float to Value?
This feature gives the customer a simple set up and improved audit process. They use this if
they want $32.25 in the tubes but want the changer to compute and dynamically alter the
ratio of coins in the tubes and give the best mix of coins ready for change.
How does it work?
The Gryphon continually computes coin levels for each tube based upon whether tubes are
naturally replenished or depleted and how often the tube is used for change. It will
dynamically adjust the mix of coins to make best use of the coins it most typically
encounters, adjusting to your consumer pool.
It will always try and have at least seven coins in any tube to ensure the exact change
indicator is kept off and will continue to add more coins to the tubes until the overall value for
the entire cassette matches the target value set by the customer.
For example, if your customer base tends to use quarters, the Gryphon will adjust the mix of
coins to compensate for quarter-heavy traffic.
Will it work immediately?
Yes. However, the initial mix of coins in the tubes may not be optimal.
14
GRYPHON OPERATION AND SERVICE GUIDE
Auto-Float
What is Auto-Float?
Auto-float operates with the optimal amount of money in the tubes needed to ensure the
exact change light is rarely lit and that change is available for vends. Generally this reduces
the float levels in day-to-day operation.
How does it work?
It tracks incoming and outgoing coins as well as bills from peripherals to determine the
optimal amount of change needed to maintain operation, averaged over a period of time,
allowing for fluctuations in customer traffic.
Will it work immediately?
Yes. However, it requires some time to gather information on how the tubes are being used.
During this time, it will run the tubes at their maximum level to ensure there is always enough
change.
• The consumer will not notice a difference.
• Auto-float will ask for a number of coins inserted to meet the auto float level. Any
coins inserted once the float level has been achieved will be routed to the cash box –
no overfill is possible.
• If a coin tube has more coins in it than is required by the auto float, the tube will
dispense coins until the correct level is reached.
• The float level will change depending on the ratio of coins accepted and coins
dispensed.
• Auto float only manages coins to cash box; it will stop routing to the cash box if they
are needed to keep the exact change light off.
• Float Up and Float Down do not operate in auto float mode.
Snapshot Float
What is Snapshot Float?
When this function is chosen, it takes a "snapshot" of the current cassette and uses that
data to set the float settings.
How Does it work?
The snapshot feature allows the operator to manually fill the coin cassette tubes to a
predetermined level or value and then save it as the operational float settings.
Will it work immediately?
Yes. The snapshot feature is only available when the unit is set to ‘Float to Level’ or ‘Float
to Value’.
