ERROR CODE DEFINITIONS
COIN DROP STUCK
Since the coin count switch in the hopper is NORMALLY CLOSED, a coin passing under the count switch
OPENS the circuit. The Controller allows only a short time for a coin to pass under and open the switch and
for a coin to drop. If the switch remains open for too long, the Controller will shut down the changer because
it is unable to count dispensed coins accurately. This message could mean that the count switch is stuck, the
count switch is broken, or there is a broken connection elsewhere in the circuit.
HOPPER JAMMED
If this message is displayed, the Controller has not detected any count signals from the hopper or the counting
circuit has remained closed. The Controller allows a specified amount of time to recognize a payout. If the
Controller has not detected a payout, it “times-out”. This message could mean that the count switch is out of
adjustment or broken. It could also mean that the hopper is jammed or unable to “pick-up” coins.
The above two (2) errors cannot be detected until the Controller
turns on the Hopper(s), and will not be detected on powerup or in
standby mode.
INPUT STUCK
An INPUT refers to a signal coming from the validator or coin mech which notifies the controller that money
(coins or bills) has been inserted into the change machine. The INPUT STUCK message refers to each input
type as being continuous, where a normal input is of only brief duration. This message points to a malfunction
in the validator or coin mech.
UNEXPECTED HOPPER PAYOUT
This message will appear if the Controller has detected a coin payout signal when the hopper has not been
“authorized” to run. The Controller has detected an unexpected open and close of the count circuit.
STACKER BUSY TIMEOUT
The bill stacker is part of a NORMALLY CLOSED circuit. When the circuit is opened, the Controller detects
that the stacker is in mid-cycle. The Controller acknowledges this by keeping the validator disabled until the
cycle is complete. A normal stacker cycle lasts only a couple of seconds. If this cycle lasts too long (for
example, if the stacker was jammed), the computer shuts down. A broken connection in the stacker busy
circuit would also cause a shutdown.
HOPPER EMPTY
The hopper has sensor strips that detect the level of coins. When the coin level falls below the strips, the circuit
is open and the hopper is considered empty. (This will occur even if there are some coins left in the hopper.)
