Faulty coin mechs can be sent to us for service at: Coin Acceptors Attn: Workshop, Unit 1 / 2 Morton Street, Parramatta NSW 2150. I recommend a registered and/or insured service to ensure proof of delivery.
When sending in your coin mechs for service include your company name and contact details (name and phone number). Ensure a street (not postal address) is included in your details as we will return it via TNT couriers.
Also include a description of the fault, as this will help us complete your repairs sooner and allow us to service the mech in case we find no fault.
The service charge is $67+GST plus any parts used in the repair. Return freight will also be charged.
The metal coin rail sits in the acceptor gate path, where the coin first enter the acceptor. Its function is to debounce the coin so reliable readings can by taken by the coin mech's sensors.
Older Guardian 6000 coin mechs have a shallower (15 degrees) rail, identified by the circular hole in the rail.
The new rail is steeper (20 degrees) and is identified by the rounded square hole in it.
If you have any Guardian 6000 coin mechs with the older rail, please contact us and we will send you some to swap over.
The current stable software version is 2.11.
You can view the coin mech's software version during startup, it will be displayed briefly after the Guardian 6000 screen, below the model number on the next screen.
Earlier software version may have issues with coin routing, poor full tube payout and tube counts.
If your coin mech has an earlier software version it needs to be sent in for service, this is a warranty upgrade service.
10c – 78 coins
20c – 59 coins
$1 – 52 coins
$2 – 49 coins
Therefore with the default setup of 20-20-$1-10-10-$2 the Guardian coin mech can hold $189.20 in change.
The following is a list of the Australian coins, the tube used for the coin and the possible locations in the cassette for that tube.
Denomination: Tube#: Possible locations:
10c: Tube #3: ABCDEF
20c: Tube #1: AB
50c: N/A: CASHBOX
$1: Tube #2: ABC
$2: Tube #5: ABCDEF
Initially the coin mech accept gate path should be cleaned, this is the area the coin first enters the coin mech and contains the sensors that read the coin. Use a damp Cloth to clean surface dirt, any persistent grime can be cleaned off using a gentle cleaner, that will not leave a residue. (we recommend Windex). Ensure the product is dry after cleaning.
If problems continue, Guardian 6000s with poor acceptance can have their coin acceptance security level changed from the default high security to standard security, this should increase the acceptance level.
The procedure to change the coin acceptance security level from high to standard is:
Enter the Guardian menu system by pressing the menu button.
The display will show Main Menu Audit, press the down arrow (B) button to get to Setup, press Enter (C) button the display will now show Setup Float, press the down arrow (B) twice until you get to Coin Config, press Enter.
The display will show Coin Config Coin Enable, press the down arrow (B) button twice to get to Security level, press Enter (C) button.
The display will now show MDB Level, press the down arrow (B) button to get to Scale Factor, press Enter (C) button.
The display will now show two pages of instructions followed by a screen showing a list of the coins followed by a H (for high security), note a screen displaying To accept al press ENTER is shown periodically, do NOT press Enter until you have finished changing all the setting you wish to change.
Use the down arrow (B) to change the H to an S (standard security) on the AU5c coin, then use the right arrow (F) to select the next coin and once again use the down arrow (B) to change the H to an S.
Then use the right arrow (F) to select the next coin and once again use the down arrow (B) to change the H to an S. Continue this procedure until the security setting for all coins have been changed, the AU$1 and AU$2 will appear on another page after the AU50c coin.
When all settings have been changed press the Enter (C) button to accept the changes.
If this does not fix the problem the unit should be returned to a Coin Acceptors service centre for service.
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.
