If the current rises above a pre-set value, then a jam is deemed to have occurred. The motor is braked
for 50ms then reversed for 150ms. After a further 50ms braking, the motor is started in the forward
direction again.
The current is tested after 100ms and if the jam has not been cleared the reversing cycle will be
repeated. This action will continue until the jam has cleared. This reversing action is effective in
clearing soft jams.
One further action is to test the current in the reverse direction during the final 50ms of the
reversing cycle. If during that time period an over current is detected, then the motor will be
braked for 50ms and then disabled for 1 second. This action limits the duty cycle sufficiently in
the case where a jam is solid in order to prevent motor damage.
6.7 Coins With Holes
The Evolution Hopper will work with most coins/tokens with holes depending on the size of the hole in
relation to the diameter. To make sure whether your desired coin is qualified within the specifications
of the Evolution Hopper please contact the Suzo-Happ technical department
The exit window has been designed so that more coins with holes will be counted correctly.
No adjustments are necessary to cope with standard and small coins.
6.8 High Security Exit Window
6.8.1 Description
The payout window uses optics consisting of an IR-Led transmitting a beam that is reflected by a
prism in an U-shaped form and received back on an IR-receiver.
The intensity of the IR-pulse is minimized, so that the (somewhat transparant) plastic coins as well as
highly reflective coins are detected as optimal as possible.
The intensity of the IR-pulse is adjusted dynamically to a higher level if the opto-sensor becomes dirty.
6.8.2 Security
- The IR-led transmits pulses with a random duty-cycle between 16 – 20%.
- When light is received when no IR-pulse is being transmitted, (exit window is 'blinded' by external
light), the hopper will stop immediately if it was running, the security led will go off and the security
output will go high (error state).
- If the opto-sensor is interrupted for more than 1 second, the hopper will also stop and go into error
state. If the coin exit becomes unblocked again and the hopper start conditions are still met, the
hopper will resume running.
6.8.3 Opto test
By holding the hopper in reset and toggling the IN3 line, the optics can be checked for a blockage prior
to paying out.
During Reset, a High on IN3 will cause a low on "Output 1" and "Output 2". Alternately a Low on IN3
will cause a high on "Output 1" and "Output 2".
NOTE:This is only true if the optics are NOT blocked.
6.8.4 Dirty opto
If the opto becomes dirty, the red led on the board starts flashing, indicating that it needs to be
cleaned. The opto-sensor remains operating reliably. If the opto-sensor becomes even more dirty, the
security output becomes high. The opto-sensor remains operational.
