7.4. 3.4 Coin Jams during payout
During a payout, a coin may block the hopper (for example if the hopper is loaded too heavily, or a
wrong coin has slipped into the hopper). In this case the motor current will rise quickly. A fully blocked
hopper motor will draw peak currents up to 7 Amp. When the power supply is not able to deliver this
peak current, the voltage on the hopper will drop.
We recommend the following power supply types from Suzo:
- 42PP0520 (dual supply: 5VDC and 12VDC)
- 42PP0530 (dual supply: 5VDC and 24VDC)
When the voltage drops below the POWER_FAIL_TRESHOLD (see Table 8: Electrical specifications)
during 20ms, the hopper will reset, aborting the payout procedure. This 20ms may seem a short time,
but remember that if the power supply is 8.0V and falling, the hopper must be able to stop and save all
payout settings before the power is gone totally.
As long as the power supply on the hopper is above the POWER_FAIL_TRESHOLD level, the hopper
will start an anti-jam operation by reversing and restarting the hopper motor.
If the motor current is greater than 3.3A during 160ms, the motor will start reversing in order to un-jam
the hopper. During anti-jamming, the current my rise to levels of 6 Amp peak.
7.5. 3.5 Power failures
The hopper measures the voltage each ms.
If the voltage drops below the POWER_FAIL_TRESHOLD during 20ms, the hopper will stop
immediately if it was running, and save all counters (CoinsPaid, CoinsUnpaid) in Non-volatile memory.
A power dip of more then 20ms will stop the hopper and save all data.
If the power returns again, the host software must retrieve the hopper status and take appropriate
action if there are, for example, unpaid coins left.
If the host machine has early-power down notification, the host machine may send an 'Emergency
Stop' command to the hopper so that the hopper will stop and save all data.
The NrCoinsRemaining is transmitted back to the host. The host machine must ensure that this value
is stored in it's own non-volatile memory.
