530 Changegiver Product Maintenance Handbook
The keypad can be in either of two possible modes at any time -
normal or shifted. The keypad in normal mode allows you to
dispense coins while in shifted mode it allows you to change some
of the settings of the product.
The yellow LED is used to indicate what status the keypad is in. If
the LED is off then the keypad is in normal mode.
To change any of the functions using the keypad the changegiver
must be in an idle state, i.e. not vending or accepting coins, and the
keypad must be enabled It is possible that the keypad has been
disabled. To enable the keypad, use the MEI

terminal to alter address 244 value from a 1 to a 0.
When the mode key is pressed, the yellow LED starts to flash. This
indicates that the keypad is in shifted mode and you can change the
settings of the available functions using the keypad keys. If, after
pressing the mode key no other key is pressed within 10 seconds,
or if the mode key is pressed a second time, the keypad will return
to its normal mode and the yellow LED will go off.
The red LED is used to indicate the status of the system. Under
normal conditions the LED remains permanently on. If an error is
detected on the changegiver then the LED will flash. If a fault is
detected on the machine, i.e blocker, then the LED will be
permanently off.

Dispensing Coins
The tube positions in the coin storage cassette are labelled A,B,C,D
on the front of the plastic. When the same letter key on the keypad
is pressed a coin will be dispensed from the equivalent coin tube.
For instance if letter key A is pressed then a coin is dispensed from
the tube held in position A in the coin store.
On a single press-and-release of a key the changegiver will pay a
single coin from the tube. To get more than 1 coin from the tube hold
the key down and the changegiver will start dispensing coins
continually. If you release the key within 3 seconds of the initial
press, then dispensing will stop after the current coin is dispensed.
If the key is held for more than 3 seconds, dispensing will latch, and
releasing the key will have no effect. The dispenser will continue to
dispense coins until the tube reaches its safe coin level (minimum
number of 2 coins left in a tube), or any key is pressed. If 2 or more
keys are pressed at the same time, then the changegiver will pay
