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.
Setting The Vend Prices.
If the Vending machine is fitted with its own electronic control board the prices are set through its menu.
Otherwise if the coin mech is either an ALQ-F70X or ALD-F70X then it is the only price control in the vending machine, the prices are set with the series of switches that are behind the acceptor head, the beige part at the top, there is a latch at the top right corner that allows the acceptor head to folded forward to reveal the switches.
There are two types of price setting, single and four price, this is dependant on the actual switch wiring with in the vending machine, it can either be wired for a single price or wired for up to four prices. The type of price setting is indicated in the coin mech by switch 10. If it is OFF then it is set as a single price coin mech, and conversely if it is ON it is set as a four price coin mech (even if there is only a single price for all four price lines.) The use of either single or four price setting is wholly dependant on the vending machine.
To change the price on a single price coin mech, set the price you want (for example $1.20, with switches 4 & 5 ON) and press the mode button that is to the right of the LED. It will turn off momentarily, then return to a steady on.
To change the price on a four price coin mech, set the price you want (for example $1.20, with switches 4 & 5 ON) and press the mode button that is to the right of the LED. The LED will start to flash, now press the selection on the vending machine you want that price set to. Repeat this process with every selection on the vending machine (to ensure that a price is set for all selections).

The Guardian coin mech can be forced to scan and update the tube coin counts by pressing buttons A + B at the same time.
New software versions do not automatically update the tube coin counts so as to preserve the coin counts for auditing purposes.
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.
Use this procedure to change the notes that are accepted and the bezel action.
